Diamond Quality Standards
Every diamond supplied natural or lab grown is evaluated against the 4Cs:
- Cut determines how well the diamond reflects light, directly affecting brilliance and sparkle.
- Color graded from colorless to light yellow; less color generally means higher value.
- Clarity refers to internal and external inclusions; fewer inclusions mean a cleaner, more valuable stone.
- Carat the weight of the diamond, with rarity increasing at higher carat weights.
Beyond the 4Cs, our grading process reviews finish, symmetry, and overall appearance to ensure every stone meets consistent quality before it is offered to Iranian buyers.

As a certified diamond supplier, we supply both natural and lab grown diamonds each independently graded and certified to jewellery manufacturers, wholesalers, and importers across Iran. Here’s what’s available:
Natural Diamonds: Earth Mined Brilliance, Sourced at the Bourse
We supply natural diamonds, formed over billions of years and graded on the 4Cs Cut, Color, Clarity, and Carat with certification from a recognised grading laboratory.
Natural diamonds remain the preferred choice for Iranian jewellery manufacturers producing bridal, investment, and heirloom-grade jewellery, where provenance and long-term value retention matter most to end customers.
Lab Grown Diamond Supplier in Iran
Lab grown diamonds are chemically, physically, and optically identical to natural diamonds, created using HPHT or CVD technology instead of natural formation. They’re graded on the same 4Cs and certified by GIA and IGI.
Demand for certified, competitively priced lab grown diamonds is growing among Iranian jewellery manufacturers looking to offer affordable, certified stock without compromising on grading transparency. We supply:

Iranian buyers with specific manufacturing requirements can request:
- Custom carat and size ranges matched to production runs
- Specific shape mixes (round, fancy, or a blended assortment)
