Brilliant beyond compare, Schwarzschild's Signature Diamond is the result of a 15-year study conducted by the Gemological Institute of America (GIA). The GIA project was the first scientific study ever to focus on the cut of a diamond, combining state-of-the-art computer modeling and observational testing by diamond and gem experts.

Cut precisely to a very narrow set of standards chosen specifically to achieve a bigger, brighter, whiter appearance, every Schwarzschild's Signature Diamond achieves the highest GIA grade for proportions, symmetry and polish. Other diamonds receiving cut grade of GIA Excellent, or AGS 000 Ideal, may be cut to a much looser set of standards. To ensure quality, value and peace of mind, each diamond is laser inscribed with the GIA certificate number and Schwarzschild's Signature Diamond logo. Your Schwarzschild's Signature Diamond may also be personalized upon your request with your own unique inscription.
