We Buy Diamonds

Diamonds have been celebrated as among the world’s most beautiful gemstones for centuries. Diamonds are often passed down through the family in the form of loose gemstones, rings, necklaces, and other jewelry. When settling an estate that includes loose diamonds and jewelry, it’s important to consult a trusted name with experience. Mark Lawson Antiques buys diamonds and has the expertise to help you get the best price.

Our Training

Many people today are familiar with the four basic guidelines of determining diamond quality, The 4Cs: Color, Clarity, Cut, and Carat weight. Standardized by the the Gemological Institute of America (GIA), the world’s leading authority on diamonds, the 4Cs provide the basic framework for evaluating any diamond. Mark Lawson Antiques has professional GIA training and can help you determine the value of your diamonds in today’s ever-changing market, with expertise in:

  • How the 4 C’s combine and interact with each other to determine your diamond’s unique value
  • Accurately assessing antique cuts including the Old European cut, Old Mine cut, Rose cut, Table cut, and Asscher cut
  • Finding the best market for selling your diamond

Buy & Sell Diamonds Saratoga Springs & Albany NY At Mark Lawson Antiques we regularly buy diamonds from clients in every area of the Albany, Schenectady, Troy, Saratoga and Glens Falls regions, the Berkshires and western Massachusetts, and southern Vermont.

We buy diamonds in both modern and older cuts, as well as fancy colored diamonds. Because we maintain a well-established international clientele, we can pay the fairest price available for your diamond. We are interested in buying loose or mounted diamonds in any shape or color, as well as chipped or broken examples. Appraisal papers or certificates are not required, but are useful if you have them because they can save time. Typically, values are higher for diamonds in their original settings and for stones 1 carat and larger. (Do you have an old empty ring setting that used to hold a diamond? We can help with that as well.)
