The Light of Principle
We've earned the loyalty of generations of customers by our principled approach to selling diamonds. We encourage customers to do extensive research and to compare our diamonds with competitors to gain complete confidence in the performance of our gems. And we stand by the quality of our diamonds with a 30-day money back guarantee.
We do not believe in using subjective salesmanship to sell diamonds, but instead rely on rigorous certification and clear optical measurements to describe the quality of our diamonds. Each David S diamond is backed by both GIA and GemEx Light Performance Analysis reports, as well as optical measurements of light quality and return.
Optical Marvels
The World's Most Coveted Diamonds
David S diamonds burst with light and fire like no other. Our diamonds are coveted by collectors and by serious buyers around the world for their brilliant performance.
Our diamonds are crafted with a single purpose: peerless optical brilliance. Each David S diamond is cut using a mastery of optical science that sets us apart from other jewelers.
Our diamonds are not just brilliant to the eye. We are favored by collectors because we provide clear, objective proof of performance. Each David S diamond comes with multiple standard certifications documenting the exceptional workmanship and brilliance of the gemstone.
Certified Diamond Assurance
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.
GIA REPORT
The GIA report is the best and most widely used rating for diamond performance. Each report contains the dimensions of the diamond as well as a rating of performance.
GEMEX REPORT
The GemEx Light Performance Report measures and certifies the optical brilliance, fire and sparkle of a diamond using a patented optical spectrophotometer.
LIGHT RETURN
A Light Path Scope is used to analyze the total light return for the diamond. This provides a valuable indicator for the overall brilliance of the diamond.
OPTICAL SYMMETRY
An optical scope is used to analyze the "hearts and arrows" symmetry of the diamond. This provides an indicator of the quality of the light distribution emitted by the diamond.
Buying with value and certainty
Diamond Buying Guide
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.
