IGI Certified Loose Lab-Grown Diamonds — Wholesale Prices From Surat, India

Bluequeen Jewels supplies IGI certified loose lab-grown diamonds at wholesale prices from Surat, India — the diamond capital of the world. Our loose diamonds are available in multiple shapes, carat weights, color grades, and clarity grades for jewelry manufacturers, diamond dealers, jewelers, and online sellers worldwide.

What Are Loose Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds created in a laboratory using CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) technology. They have the same physical, chemical, and optical properties as mined diamonds — at a significantly lower cost and with full IGI certification.

Available Diamond Shapes

We supply loose lab-grown diamonds in round brilliant, oval, cushion, heart, pear, marquise, emerald, princess, and radiant cuts. Custom shapes and specialty cuts are available on request for wholesale buyers.

Carat Weights Available

Loose lab-grown diamonds are available from 0.30 CT to 10+ CT. Popular sizes include 1 CT, 2 CT, 3 CT, and 5 CT. Melee diamonds (under 0.20 CT) are available for jewelry manufacturers and ring setters.

Color & Clarity Grades

All our loose lab-grown diamonds are graded by IGI (International Gemological Institute). Available color grades: D, E, F (colorless) and G, H (near colorless). Available clarity grades: IF, VVS1, VVS2, VS1, VS2. D-F VVS is our most popular grade for high-end jewelry.

IGI Certification Details

Every loose lab-grown diamond we supply comes with an IGI (International Gemological Institute) grading certificate. The IGI certificate confirms the diamond’s cut, color, clarity, carat weight, and lab-grown origin. IGI is the world’s most trusted certification body for lab-grown diamonds.

CVD vs HPHT Lab-Grown Diamonds

CVD (Chemical Vapor Deposition) diamonds are grown using a gas process and are the most common type of lab-grown diamond available today. HPHT (High Pressure High Temperature) diamonds are grown using the same process that forms natural diamonds. Both are chemically identical to mined diamonds. We supply both CVD and HPHT certified diamonds.
