What Are Loose Diamonds & Why Buy Them?
A loose diamond is a diamond that has been cut and polished but not yet set into any jewellery. When you purchase a loose diamond, you are buying the stone on its own — giving you complete freedom to choose your own setting, metal, and design.
Whether you are a jeweler sourcing stones for custom pieces, an investor building a diamond portfolio, or a buyer looking for the perfect center stone, loose diamonds offer unmatched flexibility and value.

Talk to Juned DirectlyFrequently Asked Questions
Everything you need to know about buying loose diamonds from Zahra Diamonds.
A loose diamond is a cut and polished stone that has not yet been mounted into any jewellery setting. Buying loose gives you the freedom to choose your own setting, metal type and design, and typically represents better value since you are paying for the stone’s quality alone — not a pre-made piece.
Yes. Every loose diamond we supply comes with a GIA (Gemological Institute of America) or IGI (International Gemological Institute) certificate. These certificates confirm the diamond’s 4 C’s (cut, colour, clarity, carat), shape, measurements, and any treatments. We never sell uncertified stones.
Absolutely. Wholesale supply is our primary focus. We supply single stones as well as large parcels of melee diamonds and matched lots. Whether you need 10 pieces or 10,000 pieces, we can accommodate with consistent grading and competitive Rapaport-linked pricing. Contact us on WhatsApp with your parcel requirements.
Natural diamonds are formed deep in the earth over billions of years and are mined. Lab-grown diamonds are created in a controlled environment using HPHT or CVD technology and are chemically, physically, and optically identical to natural diamonds. Lab-grown are typically 50–70% less expensive, making them popular for jewellery manufacturing. Natural diamonds tend to hold more value as rare collectibles and investments.
Yes, we export loose diamonds worldwide. Shipments are fully insured, securely packaged, and sent via trusted international couriers including Malca-Amit and Brinks. We provide all required export documentation, including Kimberley Process (KP) certificates for conflict-free certification and commercial invoices for customs.
We cater to both single-stone buyers and large-parcel wholesale orders. There is no strict minimum for individual certified diamonds. For melee and bulk parcels, minimums may apply. Contact our team on WhatsApp to discuss your specific requirement and we will advise accordingly.

Natural Loose Diamonds vs Lab-Grown Loose Diamonds
Buyers today have two primary options when purchasing loose diamonds. Natural loose diamonds are earth-mined and carry inherent rarity and investment value. Lab-grown loose diamonds are physically identical but produced in weeks using CVD or HPHT processes, carrying a significantly lower price point. Zahra Diamonds supplies both categories with full certification.
How Loose Diamonds Are Graded
All loose diamonds are graded using the internationally recognised 4 C’s framework — Cut, Colour, Clarity and Carat weight — standardised by the Gemological Institute of America (GIA). The IGI also issues widely accepted grading reports, especially for lab-grown diamonds. Zahra Diamonds only deals in diamonds bearing reports from these two world-leading laboratories.
Buying Loose Diamonds for Investment
Certified loose diamonds — particularly high-colour, high-clarity natural diamonds of 1 carat and above — have historically served as a portable store of value and alternative investment asset. Zahra Diamonds works with individual investors and family offices to source investment-grade loose diamonds at competitive prices with proper documentation for insurance and resale purposes.
