At Variation, our Lab Grown Diamonds collection is curated for those who seek impressive sparkle, IGI-certified assurance, and refined craftsmanship in every stone.

Understanding Lab Grown Diamonds — A Buyer’s Overview
What Makes Lab Grown Diamonds Identical to Mined Diamonds?
Lab grown diamonds share the same pure carbon composition and crystalline structure as natural diamonds. They are real diamonds formed under controlled conditions that recreate the pressure and temperature found deep within the earth.
Variation’s lab grown diamonds are produced using:
- CVD (Chemical Vapor Deposition)
- HPHT (High Pressure High Temperature)
Both processes result in diamonds with identical hardness, refractive index, and optical performance to mined diamonds, ensuring enduring brilliance in every setting.
Customers choosing Variation enjoy:
- Exceptional brilliance and fire
- Strong structural integrity
- Reliable light performance
- Verified quality through IGI certification

Do lab grown diamonds look different from mined diamonds? +
