A revolutionary new cut for maximum brilliance 

For the first time, a Princess with brilliance that rivals an Ideal Round diamond. 

   In 2011, Heinrichs partnered with New York diamond cutters to offer a princess cut with an unprecedented light return, the FireMark® Princess. This diamond 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! 

An astounding average light return of 98%

“Excellent” rating from GIA for Polish

"Excellent" rating from GIA for Symmetry

“Excellent” rating from GCAL for Light Performance

What distinguishes the FireMark® Princess:

1. “A FireMark diamond will appear about 10% larger than a typical Princess Cut of the same carat weight”.

2. Patent pending “Double Crown” – additional facets and distinctive angles capture the diamond’s life like no other Princess diamond in the world.

3. Shallower depths – assuring you don’t pay for weight you can't see.

4. Smaller tables, exacting angles, even girdles and facets that are perfectly aligned maximize the diamond’s fire, brilliance and scintillation.

5. Every FireMark® Princess is laser inscribed on the girdle with its own individual serial number and comes with both a GIA & GCAL certificate.
