How We Buy Diamonds

We buy statistical samples of all diamonds from established vendors, for a regulated commodity using an audited price discovery process.

  • For next day delivery to your IGI Lab ONLY.
  • Round, 0.21 to 0.75 (soon 1.99) carats, D-L, FL-SI2, EX-VG Cut.
  • Diamonds above $750/ct must already be GIA Graded.

We instantly buy or bid on some, or all, of your diamonds.

  • We may accept your asking price, or make an instant cash bid.
  • The commodity is not jewelry, we need all types of diamonds.
  • Inclusions welcome, printed GIA paperwork not required.
  • Bids change frequently as we fill our commodity orders


Accept or Reject our Offer.

  • Our system generates an instant purchase order.
  • Deliver to your local IGI Lab – they verify that the diamonds match the certs, or grade ungraded diamonds for us.
  • We pay COD, and never return a matching diamond.

We Buy or Bid Automatically

Upload diamonds, with a price for immediate, COD delivery. Some diamonds we buy at your price, and for others, we make a bid. We buy statistical samples of all diamonds, and our system automatically adjusts our bids. If you accept our bid, we instantly send you a purchase order. We always pay COD after GIA confirmation.

You Deliver Locally

You deliver the diamonds to your IGI Lab by the end of the next business day. They inspect diamonds for us, to confirm that they match the GIA Report. At prices under $750/ct, we buy ungraded diamonds, based on your assertion of quality, and the IGI grades them for us. We pay more for graded diamonds, and ones already in the USA.

COD, No Returns

Once the IGI confirms your diamonds, we pay in full by bank wire. For uncertified diamonds, we pay after grading. Your diamonds must match the quality you asserted.

We buy diamonds based on the GIA grading report and the price, and never reject a diamond that matches the cert.

Millions of Diamond Types

The Range

We buy natural diamonds, round shape, 0.21 to 0.75 carats (1.99 ct soon), D to L Color, Flawless to SI2 Clarity, Excellent to VG Cut, Excellent to Very Good Polish, Excellent to Very Good Symmetry, None to Light Milky, None to Strong Blue Fluorescence.

GIA Grading: Diamonds above $750/ct must be GIA certified (any location, any year). We do not need the printed GIA paperwork. For diamonds below $750/ct, we buy ungraded diamonds based on a quality you assert, and have those diamonds graded by the IGI. We pay more for diamonds already GIA graded.

No Negotiating

We buy thousands of diamonds from hundreds of vendors daily, based strictly on their GIA grades and price. We automatically adjust our prices, and don’t negotiate individual purchases. Throughout the day, as we need a smaller number of specific diamonds, we are more likely to accept your asking price. Our market making system automatically raises our bids to fulfill our statistical sampling requirements. If you hold out, we will likely pay more, but then again, another vendor might offer similar stones and we won’t need yours.
