Welcome to London Diamond Traders

Diamond

We buy certified diamonds from GIA, HRD, and IGI. We only require the certificate number from you, and we can utilise that to offer you a quote no matter where you are.

Additionally, we purchase uncertified diamonds, with an emphasis on old-cut gems. While information about the diamond's carat weight, colour, clarity, and cut can be used to estimate value in these circumstances, visiting offices will result in an accurate price.

The four Cs, as they are known in the trade, play a significant role in determining the value of your diamond.

CARAT: The diamond's weight

COLOR: A diamond's worth increases since it is rarer and more valuable the whiter it is.

CLARITY: The higher any valuation will be, the cleaner the diamond is.

CUT: The way a stone reflects light to give it the distinctive sparkle of a diamond.

You have two options for payment:

  1. While you wait, as a BACS transfer to your bank account, or as a same-day payment if your diamond was turned in via postal service.
  2. If you come to the valuation in person, as a straight cash payment.

Because we are diamond wholesalers, we acquire diamonds for stock as opposed to many other dealers who buy with the intention of reselling them to further wholesalers. By doing so, we cut out the "middle man" and can consequently provide the greatest price for your diamonds or jewellery.
