India’s Place Among Lab Grown Diamond Makers

India stands among the leading makers of lab grown diamonds. It grows rough diamonds, cuts them, and sets them in jewellery. Most steps of the chain can happen at home, from growing to selling. The sections below show how that chain works.

India Grows, Cuts, and Polishes

India is widely recognised as one of the world’s leading lab grown diamond producers, generally ranking behind China. Its estimated global production share varies by year and source. Many Indian growers use the CVD method. Lab grown diamonds India grows often get cut and polished in the same country.

  • Volume: India exported 18.8 million carats of polished ones in 2025-26.
  • Comparison: Polished natural exports stood at 16.0 million carats.
  • Value: Lab grown export value fell 10.6 percent to about US$1.1 billion.
  • Jewellery: Exports of studded jewellery with lab grown diamonds grew 31.3 percent.
  • Recent trend: April to September 2026 polished exports rose 17 percent in dollars.

How India’s Lab Grown Diamond Supply Chain Works 

A diamond passes through many hands before it sits in a ring. Each hand adds skill and cost. Knowing the path helps you read a price tag. Here is the usual route in India.

  • Growers: Factories produce rough diamonds of many sizes.
  • Cutters: Skilled workers plan, cut, and polish each rough diamond.
  • Graders: Laboratories test each polished diamond and issue a report.
  • Jewellers: Craftspeople set diamonds in gold or platinum.
  • Retailers: Stores and websites sell the finished piece.

Why Surat Leads Lab Grown Diamond Cutting and Polishing 

Surat is a major centre for diamond cutting and polishing in India. The city handles a large share of the country's diamond processing work. Surat's lab grown diamonds reach jewellery markets across India and overseas. Mumbai also plays a significant role in the diamond trade. 

Why Surat Works So Well

  • Skills: Many workers there learned diamond cutting over many years.
  • Closeness: Dealers, factories, and testing labs sit near one another.
  • Contacts: Old trade links connect the city to buyers overseas.

HPHT and CVD: What Buyers Should Know

Both processes give real diamonds. One is not better than the other. Many reports state which method was used. Judge a diamond by its grades and cut.

Government Support for Indian Growers

Policy has backed Indian growers. Budget 2023-24 cut the customs duty on lab diamond seeds from 5 percent to nil, under set conditions. It also gave IIT Madras approximately ₹242 crore over five years for local seed and machine research. India aims to depend less on imports.

What the Export Boom Means for Buyers

Big export numbers affect what you pay and what you can find. Large volumes mean many sellers compete for your order. A 31 percent rise in carats, paired with lower value, points to cheaper diamonds. Rising diamond jewellery exports show that finished pieces are in demand too.

  • Choice: Many growers and cutters mean more sizes and shapes to compare.
  • Pricing: Lower rough costs can reach shoppers as sharper quotes.
  • Caution: Cheap does not mean good, so still read the report.

Other Countries in the Lab Grown Diamond Trade

India is not the only maker. China, the United States, Singapore, and parts of Europe and the Middle East also grow lab grown diamonds. Each plays its own role in global trade. The table shows where they stand next to India.

Country Main strength Common method
India Growing, cutting, and polishing CVD
China Largest growing volume HPHT
United States Research and strong buyer demand Varies
Singapore and others Newer growing hubs Varies

The Biggest Growers by Volume

China grows the biggest share of the world’s lab grown diamond. Estimates range from about half to well above half, so no single figure is final. Most Chinese factories use the HPHT method, and Henan province is a major centre. Cheap, plentiful supply from China helped push global prices down.

  • Output: Estimates run to millions of carats a year.
  • Method: Many factories use HPHT technology to grow diamonds.
  • Effect: Bigger supply has lowered prices for buyers everywhere.

Early Pioneers and Newer Hubs

General Electric researchers produced the first widely recognised lab grown diamonds in 1954. American producers still grow diamonds, and US shoppers anchor global demand. Singapore and the Middle East have newer growers. A few European firms also grow diamonds.
