We advocate a clear, rational approach to buying diamonds.  Whether you are spending $1,000 or $1 million, we encourage all customers to:

  • Learn  by spending time reading about diamonds and diamond performance. There are helpful resources online, and we have also compiled a library of educational materials for our customers' benefit.
     
  • Compare  by shopping at several jewelers to ensure that you are making the best possible choice under the least pressure.
     
  • Plan  by starting to shop as early as possible (we strongly recommend 3 months or more)  to ensure that you have time to build a confident decision and can wait for the right diamond to be cut if necessary. 
     
  • Prove  that you are getting the best value for your budget.  Your jeweler should allow you to examine and test the brilliance of the diamond, and provide at least 2 different certified results from GIA, GemEx, or other leading rating agencies.

Selecting a diamond

Once you are ready to begin selecting a diamond, we have assembled a clear, fact-driven approach to finding a diamond with the best possible performance for value. This is the same approach David S uses to select our own renowned diamonds.

 

Prove its worth

A jeweler should provide at least two 3rd-party certifications which prove the quality of your diamond.
David S. Diamonds stands behind our diamonds by providing four proof points for each diamond.  Our customers love us for the certainty we provide to prove the peerless brilliance of our diamonds.
