The Firemark Diamond
A revolutionary new cut for maximum brilliance.
For the first time, a princess cut and a cushion cut
with brilliance that rivals an Ideal Round diamond.

Perfect Cut. Perfect Brilliance.
FireMark: The Most Perfectly Cut Princess Diamond in All the World. The FireMark® Princess has been put to the test by the Gemological Institute of America (GIA), the world’s foremost diamond authority, and the Gem Certification & Assurance Lab (GCAL), a leader in grading the light performance of diamonds. And the results are unprecedented!
All FireMark® diamonds have a superior finish and light return that rivals an Ideal Cut Round, and they all come with two certs (one from GIA that is for grading only, and one from GCAL that verifies the light performance). A FireMark® diamond has an average 98% light return, compared to a standard princess cut's 80% average light return. In addition to their spectacular brilliance, FireMark® diamonds have a shallower depth than typical princess cuts, making them appear about 10% larger than a standard princess cut of the same size.
What distinguishes the FireMark®:
- "Excellent” grades for Light Performance from GCAL.
- "Excellent" ratings from the GIA in both Polish and Symmetry.
- "A FireMark diamond will appear about 10% larger than a typical Princess Cut of the same carat weight.”
- Patent pending "Double Crown” – additional facets and distinctive angles capture the diamond’s qualities, like no other Princess diamond.
- Shallower depths – assuring you don’t pay for weight you can't see.
- Smaller tables, exacting angles, and even perfectly aligned girdles and facets maximize the diamond’s fire, brilliance, and scintillation.
