10 Myths About Lab Grown Diamonds: Separating Fact from Fiction

Lab grown diamonds have revolutionized the jewelry industry, yet misconceptions persist across India and globally. Despite being chemically, physically, and optically identical to mined diamonds, synthetic diamonds face skepticism rooted in outdated information and marketing campaigns from traditional diamond miners. This comprehensive guide debunks the 10 most persistent myths about lab grown diamonds with scientific evidence, industry facts, and real consumer experiences from Indian buyers.

The Indian lab grown diamond market has experienced unprecedented growth, with production increasing by 300% between 2019-2024. Major Indian manufacturers like New Diamond Technology, Greenlab Diamonds, and Renaissance Diamonds now supply over 60% of global lab grown diamond production. Understanding the facts helps Indian consumers make informed decisions when purchasing engagement rings, wedding jewelry, or investment pieces.

Understanding Lab Grown Diamond Science

Before addressing specific myths, it's crucial to understand how lab grown diamonds are created. Two primary methods dominate production: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both processes replicate natural diamond formation conditions, creating genuine diamonds in weeks rather than millions of years.

HPHT Process: Seeds of natural diamonds are placed in carbon-rich material and subjected to temperatures of 1,500°C and pressures 1.5 million times atmospheric pressure. This mimics conditions 100 miles below Earth's surface where natural diamonds form. Leading Indian companies like KK Diamonds and Laxmi Diamond use advanced HPHT technology producing Type IIa diamonds - the purest diamond type.

CVD Process: Diamond seeds are placed in a sealed chamber filled with carbon-rich gases. Temperatures reach 800°C while microwaves break down gases, depositing carbon atoms layer by layer onto the seed. Indian manufacturers like Surat Diamond Works and Brilliant Earth India have perfected CVD technology, producing diamonds with exceptional clarity and minimal inclusions.
