The Finer Points

Ritani Reserve diamonds are unique in that they have passed stringent grading criteria for cut, and for sparkle. Each Ritani Reserve diamond comes with two diamond certificates: one documenting that the diamond embodies the proportions that produce the most sparkle, and a second, documenting that the diamond produces the most intense sparkle, shown in patterns of flash and fire.

These diamonds have been graded by either the American Gem Society Laboratories (AGSL) or the Gemological Institute of America (GIA), the most widely-respected labs in diamond grading worldwide, and have received the finest cut-grade available. This guarantees they are cut to maximize beauty, not carat weight, and will look gorgeous when viewed in a ring.

Each diamond has also received an AGSL Scintillation Report which uses proprietary AGSL technology to analyze the science behind the artistry of each diamond. The Scintillation Report shows the amount of sparkle — measured by the intensity of the flash (white light) and fire (colored light) each diamond produces — revealing that these diamonds produce the most sparkle of any diamond available.

Reference Diagrams

This diamond diagram shows the diamond's inclusions. They have been marked by the GIA gemologist as they appear from the top (looking through the table) and from the bottom (looking through the pavilion). Note that because the gemologists use pens to mark where the inclusions appear, the actual inclusions may be smaller than the marks.

The light areas in the pattern indicate where you will see large facets reflecting flash or fire. The dark areas indicate areas where you will see many small facets reflecting flash or fire. You’ll see the beautiful effect of this patterning when you gently rotate the diamond or ring in your hand.
