Sell Your Diamond

We'll Pay More For Your GIA or AGS Certified Diamond Than Other Places.

We are seeking high quality certified diamonds only. Your diamond must be certified by the Gemological Institute of America (GIA) or the American Gem Society Laboratory (AGS).

Due to overwhelming demand for our service and the requirements of our discriminating customer base, we require that your diamond meets this criteria:

  • GIA or AGS Lab Certified
  • 3/4 Carat or Bigger
  • D, E, F, G, H, or I in Color
    We DO NOT BUY fancy color diamonds.
  • Flawless, VVS1, VVS2, VS1, VS2, or SI1 in Clarity
  • Ideal, Excellent or Very Good Cut Grade

We buy GIA & AGS certified diamonds only!

We DO NOT BUY or CONSIGN color enhanced or clarity enhanced diamonds.

We’ll give you the highest amount of cash for your precious diamond fast and with no hassles.

If you'd like to convert the value of your GIA or AGS certified diamond into the highest amount of cash possible, then let our friendly diamond buying team at Washington Diamond help you. We will quickly and confidentially evaluate your diamond and make you an offer.
