The Glitter in Your Eyeshadow Was Almost Certainly Mined by Hand in Jharkhand

India controls 60% of the world's mica. Mica makes your eyeshadow shimmer and your car paint shine. Here's who pays the price for it.

Here is a fun fact nobody puts on a makeup label: the shimmer in your eyeshadow, the pearlescent finish on your lipstick, the metallic fleck in your foundation — it almost certainly began its life in a shallow pit dug by hand in a remote corner of eastern India, likely in the state of Jharkhand, more than 1,200 kilometres from Mumbai and a world away from the glossy aisles of Sephora.

The mineral responsible for that shimmer is mica. You may never have heard of it by name, but you have almost certainly held it, worn it, driven it, and stared at it through a screen. It is on your face every time you wear makeup. It is on your car every time someone admires the metallic sheen of the paint. It is inside the capacitors and insulators of the laptop or phone you are reading this on. Mica is everywhere — and yet the story of how it gets from a crumbling hillside in Jharkhand to a high-end cosmetics counter in Paris or New York is one of the most uncomfortable intersections of global supply chains, rural poverty, ESG theatre, and industrial dependence that modern commerce has produced.

What Exactly Is Mica?

Mica is a group of 37 naturally occurring silicate minerals that form in flat, layered sheets, a structure that gives them a set of properties almost nothing else in nature replicates. They split into impossibly thin, transparent flakes. They are chemically stable, thermally resistant, non-conductive, and — crucially for anyone who has ever admired a sunset-toned eyeshadow palette — they refract and reflect light with a natural iridescence that no synthetic material has entirely replicated at scale.

Mica is light and flexible, possesses a glittery sheen, and is a good electric insulator and thermal conductor, making it an important input product in a variety of downstream products, including cosmetics, electronics, and paint. The most commercially important types are muscovite (the pale, glassy variant that dominates the cosmetics world) and phlogopite (a darker, heat-resistant variant critical for industrial insulation). Both are found in abundance inside granite and pegmatite rocks, the kind that underpin much of peninsular and eastern India's ancient geology.

On a cosmetics ingredient list, you will find mica listed as "mica," "potassium aluminium silicate," or "CI 77019." It is what gives body lotion a soft luminosity, makes BB creams look like they contain light, and provides the kind of shimmer that no amount of synthetic pigment has convincingly reproduced — at least not at the price point the global beauty industry has come to expect.

A Mineral That Powers Industries You Wouldn't Expect

Mica's story is not only a cosmetics story. The beauty industry gets most of the attention in mica debates precisely because it is visible to consumers. But mica's industrial footprint is far wider and arguably more structurally critical.

Nearly 45% of total demand arises from electronics, where mica ensures enhanced efficiency and durability. Around 40% of automotive formulations now incorporate mica to improve mechanical strength and thermal resistance. 35% of cosmetic products integrate mica-based pigments to provide shine and smoothness.

In electronics, mica's dielectric strength — its resistance to electrical breakdown — makes it essential for capacitors, resistors, and insulators used in everything from power transformers to radar circuits to the microelectronics inside electric vehicles. In the automotive sector, beyond its use in metallic car paint (that deep, flecked finish you see in premium automotive advertising), mica is used in gaskets, firewall insulation, and the thermal barriers that protect EV battery packs. In construction, it is added to cement, plaster, asphalt, and roofing materials. It is even used in toothpaste, where it acts as a mild abrasive and gives a whitening shimmer.

The global mica market was valued at USD 654.92 million in 2024 and is expected to grow to nearly USD 890.12 million by 2032. That is not an enormous number by commodity standards, but the leverage effect is enormous: a small amount of high-quality mica contributes outsized value to the final products it enters — products worth, collectively, hundreds of billions of dollars per year.

Why India? The Geology of Dominance

India produces 60% of the world's mica. In India, mica mines are found mainly in three states: Jharkhand, Rajasthan, and Andhra Pradesh. 95% of the country's mica is extracted solely from these three states.

This is not an accident of industrial policy. It is a function of geology that goes back hundreds of millions of years. The eastern and central Indian plateau sits on some of the world's oldest and most mica-rich igneous and metamorphic formations. The "mica belt" is a geological feature stretching from Gaya district in Bihar westward through Nawada, Koderma, Hazaribagh, and Giridih in Jharkhand — a crescent of subsurface wealth some 40 kilometres wide at its widest point, first systematically exploited by British colonisers in the late 19th century, who quickly recognised it as one of the empire's most valuable mineral assets.

Locals have mined mica in this part of India for millennia, using it both for decoration and Ayurvedic medicine. But everything changed in the late 19th century, when British colonisers discovered the valuable mineral and nicknamed the area "the mica belt." By the time India won independence from British rule in 1947, the country was approaching a count of 700 mines filled with 20,000 workers.

Rajasthan, the other major producing state, contributes a different character of mica — particularly valued for its superior electrical insulation properties, with production concentrated around Bhilwara, Ajmer, and Jaipur. Andhra Pradesh, particularly the Nellore district, is the state where mica mining is actually legal at scale, and where the formal, regulated industry largely operates. This legal geography will matter enormously when we follow the supply chain.

How It's Actually Mined

Here is where the story diverges sharply from the kind of clean, photogenic mineral-sourcing narratives that appear in sustainability reports.

The dominant method of mica extraction in Jharkhand — the state that produces the largest share of India's mica — is artisanal and small-scale mining, much of it conducted in shallow open pits and narrow underground shafts dug by hand. The geology requires it: mica veins in this region are thin and irregular, running through hard rock in a way that makes large-scale mechanised extraction uneconomical for the grade of stone being extracted. What it takes, instead, is people — small bodies, often, able to work in shafts sometimes no wider than a metre.

The mica that comes out of Jharkhand is technically classified as "scrap mica" — pieces and flakes that were either abandoned in dump piles from older closed mines or freshly extracted through artisanal digging. Once extracted, this scrap mica is processed into mica powder and flakes, which are the forms in which it enters global supply chains.

There is an additional legal dimension that makes Jharkhand's mica particularly fraught. The Forest Conservation Act of 1980 banned mining in Bihar and then Jharkhand (which was formed out of Bihar in 2000) to protect the forests in the state. Since then, all large-scale mining operations for mica in Jharkhand have closed. Families living in Jharkhand visit the dumping yards of these closed sites as well as active open-pit sites to pick, mine, and sort scrap mica. In other words, a significant proportion of the mica that leaves Jharkhand is extracted illegally — not by a clandestine criminal operation, but by entire villages of people with no other economic option, operating outside any formal regulatory framework, with no labour protections and no occupational safety standards.

Who Pays the Price

The communities around Jharkhand's mica belt are among the poorest in India. Jharkhand itself consistently ranks at or near the bottom of India's human development indices. When the formal mines closed after the Forest Conservation Act, the local economy — which had been built around mica for over a century — did not diversify. It simply went underground, literally and figuratively.

In Jharkhand and Bihar alone, it is estimated that around 30,000 children work as mica pickers, collecting mica off the ground adjacent to mines. They are among the some 300,000 members of mica-dependent community villages.

The 2023 study commissioned by the US Department of Labor — one of the most rigorous recent examinations of the issue — found that 80% of the focal children who engaged in mica-related activities in the past year met the definition of child labour. Children as young as four and five collect mica flakes from open pits and dump heaps. Older children sort the fragments by hand. The hazards include collapsing mine shafts, silica dust inhalation (which causes tuberculosis and progressive lung disease), and the physical toll of carrying heavy loads over uneven terrain without protective equipment.

The wages paid at the base of this supply chain are strikingly low even by rural Indian standards. Mica pickers in Bihar and Jharkhand currently earn 10 and 8 INR per kg on average, respectively. Household incomes in mica-dependent communities range from approximately 3,800 to 5,600 INR per month — significantly lower than the estimated living income of 15,000 INR per month. To achieve a living income for a typical mica picker family, the average price paid per kilogram would need to increase roughly five-fold, from 9 INR to 41 INR per kilogram.

That gap — between 9 rupees and 41 rupees per kilogram — is the gap between extractive poverty and subsistence. And it costs, at the cosmetics end of the supply chain, approximately the equivalent of a fraction of one cent per eyeshadow palette. The numbers are not technically difficult to resolve. The supply chain architecture, however, is another matter.

The Supply Chain: From Pit to Palette

The way mica moves from a pit in Jharkhand to a cosmetics factory in Germany or South Korea is through a chain of intermediaries — local collectors, regional aggregators, processing units, and exporters — that is deliberately or incidentally opaque.

At the base sit two parallel realities. In Jharkhand and Bihar, artisanal miners — paid ₹8–10 per kilogram — feed mica into a network of village-level collectors with no paper trail. Simultaneously, licensed mine operators in Andhra Pradesh and Rajasthan extract mica legally, with formal employment records and export documentation. Both streams converge at the regional aggregator level, where mica is ground, sorted, and flaked at processing hubs — principally in and around Kolkata — before reaching Indian exporters. From there it travels to international pigment manufacturers in Europe and China, who transform it into the coated, colour-graded powders that cosmetics and automotive paint companies actually buy.

The majority of mica mining takes place in Jharkhand and Bihar, but there are hardly any legal mines in these states, so the mica from these states is exported using the licenses of legal mines in Andhra Pradesh and Rajasthan. Traders simply misrepresent the origin of the mica. At each stage of that chain, the paper trail says something that may or may not correspond to what actually happened at the mine.

Who Operates in This Industry

Understanding who actually operates in India's mica sector requires distinguishing between the formal, export-facing layer of the industry and the informal extraction economy underneath it.

On the public sector side, the Indian Bureau of Mines (IBM) in Nagpur is the statutory body that publishes official production data, sets quality standards (the IS:9299 series), and monitors mine safety — though its data systematically undercounts Jharkhand's informal output. Rajasthan State Mines and Minerals Ltd (RSMML) oversees mining leases in Rajasthan, providing the only formal governance layer over that state's mica operations. The National Mineral Development Corporation (NMDC) is India's largest state-owned mining company, setting the regulatory benchmark for extraction practices even though mica is not its primary focus.

Among Indian private players, Gunpatroy Pvt. Ltd (GR Mica), founded in the colonial era and based in Kolkata, is one of the most widely cited in supply chain research — a major processor and exporter serving both electronics and cosmetics sectors globally. MP Mica Enterprises, established in 1910 in Giridih at the historic heart of the Jharkhand belt, now operates leased mines in Rajasthan's Bhilwara district alongside its Jharkhand-era trading operations. The Premier Mica Company, founded in 1945 at Gudur in Andhra Pradesh, operates from the one state where large-scale mining remains fully legal. Vasundhara Micron (part of the Nalwaya Group, est. 1955) is among the few Indian processors with publicly verifiable ISO 9001:2015 certification — a rarity in a sector where certification is often nominal. Sudarshan Chemical Industries, India's largest pigment manufacturer, is the key domestic link between raw mica and formulated pigment products ready for international cosmetics brands.

At the international processing level, Merck KGaA of Germany is the world's largest producer of mica-based effect pigments under the brand Iriodin, sourcing the majority of its mica from Jharkhand and Bihar. It is the founding president of the Responsible Mica Initiative and has funded three schools, five vocational training centres, and a health centre serving 20,000 residents in Bihar since 2012 — among the most substantive corporate interventions in the region. France's Imerys processes and distributes mica across construction, paints, plastics, and cosmetics markets. Belgium's COGEBI Group, founded in 1929, specialises in high-grade mica-based insulation for electronics, energy, and aerospace applications.

The Responsible Mica Initiative, founded in 2017, now has over 80 member organisations representing more than 50% of Jharkhand and Bihar's mica exports by volume. Its original 2022 deadline to eradicate child labour was missed. Its current target is a living wage for all mica workers by 2030.

The Certification Theatre

All of Beautycounter's mica suppliers were able to produce third-party certification attesting to ethical labour practices, but it was unclear what, if anything, was behind those certificates. "If a supplier didn't even know where their product was coming from, how can they hand us a certificate that says, 'We feel confident'?" explained Beautycounter's supply chain director.

The reality is, the supply chains around mica simply are not developed enough for anyone to ensure that children are not working, let alone make claims about the safety or wages for adults. Third-party certification companies suffer from corruption, and there are issues throughout the current verification processes. Every cosmetics company approached by investigative journalists on the subject of mica origin has declined to comment on how they guarantee where in India their mica comes from.

The 2022 deadline passed. In 2023, the RMI set a new goal for its members to implement a living wage for all mica workers in the states of Jharkhand and Bihar by 2030. The goalposts moved. The mining itself has not changed significantly.

The Synthetic Option and the Exit Dilemma

One response to this complexity is to swap out natural mica for synthetic alternatives. Fluorophlogopite — lab-grown synthetic mica — can replicate many of mica's optical properties and is produced entirely outside any problematic supply chain. Lush Cosmetics has only used synthetic mica since 2018 because "natural mica is a no-no" due to ethical reasons. Other brands have followed.

But the synthetic exit is not without its own complications, and not only technical ones. The more fundamental problem is what happens to the communities left behind when global demand disappears. Abandoning the existing sources leaves communities like these worse off, but staying in is rife with problems too. If the 300,000 people who depend on mica income in Jharkhand and Bihar lose that income stream without any replacement, they do not transition to other sectors overnight. They fall deeper into poverty. This is the dilemma that has paralysed well-intentioned brands for a decade: the least harmful short-term option for children in mica mines is not necessarily for the supply chain to be abandoned.

Cosmetic-grade mica powder commands $1,000 to $3,000 per ton on international markets. The families who harvest the raw mineral receive, at 9 rupees per kilogram, roughly $109 per ton. The gap between what is paid at the bottom of the chain and what mica is worth by the time it crosses a border is not simply a margin — it is the operating logic of a supply chain structured to extract maximum value at minimum cost from people with no alternatives and no legal protections.

Why Nothing Has Fundamentally Changed

The mica industry's reform discourse tends to recycle the same vocabulary — certification, traceability, due diligence, living wage — on a roughly five-year cycle. Each round of investigative journalism, each NGO report, each corporate sustainability commitment generates a flurry of pledges. The structural conditions that produce child labour in Jharkhand's mines persist.

Those conditions are not primarily a failure of corporate ethics. They are a function of illegal mining operating in a governance vacuum (mica extraction in Jharkhand has no legal pathway, since the Forest Conservation Act remains in force), a supply chain architecture that is designed for opacity rather than transparency, and a global commodities market that prices mica as if the labour at the bottom of the chain is costless.

The European Union approved new regulations in July 2024 aimed at ensuring ethical sourcing of natural minerals, including mica, in cosmetics — adding regulatory weight to what had previously been voluntary commitments. Whether this translates into material change at mine level depends entirely on enforcement mechanisms that reach back through five or six layers of an Indian supply chain that begins in a forest that, legally speaking, should not contain a mine at all.

The Glitter in the Machine

Mica is not a conflict mineral in the formal international classification — it is not diamonds or coltan, it does not fund armed groups, it is not subject to Dodd-Frank reporting requirements. This has given the industry a technical out that it has, at various points, used gratefully. It is also a mineral that no one has successfully found a complete substitute for across all its applications simultaneously. Synthetic mica works well in cosmetics. It does not yet replace mica in high-voltage industrial insulators or in the thermal management systems of EV batteries.

The demand for mica will grow. The electronics industry's appetite for it will accelerate as electric vehicles, renewable energy infrastructure, and advanced electronics manufacture expand. Electronics applications requiring consistent material behaviour currently dominate end-use demand. India will remain the world's largest supplier for the foreseeable future, because no other country has the combination of geological resources, processing infrastructure, and — most critically — the kind of labour costs that have made Indian mica globally price-competitive for over a century.

The fun fact with which this piece opened is worth sitting with: the shimmer on your cheekbone almost certainly passed through a place where families with no other income source sent their children to dig in the dark. The global mica market is worth roughly $655 million a year. The margin between what those families are paid and what a living income would require is measured in cents per kilogram. The gap between what is technically solvable and what has actually been solved is, a decade into the industry's most concentrated reform effort, still very wide.

There is mica in your phone, in your car, in the socket on your wall. It is an invisible mineral running through the visible world. The question of who bears the cost of that invisibility is one the industry has not yet answered — not because the answer is unknown, but because the answer is inconvenient.
