Special Cut Diamond Shapes


Radiant Star Cushion

Traditional round brilliant and cushion cut diamonds have always been cut with 58 and 57 facets. At Helzberg Diamonds, a bold new approach to diamond cutting created rounds and cushions with 145 facets. The additional surface area of those extra facets means the diamond has more potential for sparkle, but that's not enough. The facets must be carefully arranged in order to capture and play with the light as much as possible, resulting in an exceptionally brilliant and scintillating diamond. Certified by the International Gemological Institute, the certificate of authenticity provides an accurate statement of the diamond's weight, color and clarity, based on an internationally recognized system. GemEx (the expert in light-performance analysis) objectively and scientifically evaluates the light performance of the diamond by measuring the rates of the diamond's white light (brilliance), color light (fire) and scintillation (sparkle). In order for a diamond to earn the name Helzberg Radiant Star, it must have ratings in the "very high" end of the scale on two of the three GemEx measurements, with none of the measurements lower than "high".

Rand Diamond

RCDC Original Radiant Cut Diamond

RCDC sets the standard for evaluating and measuring radiant cut diamonds. The Radiant Cut Diamond combines the classic elegance of the traditional emerald cut shape with the sparkle of the "brilliant" cut. Until the Radiant Cut was developed and patented in 1977 by Henry Grossbard, RCDC's founder, people attracted to the elegance of the emerald cut shape had to compromise on brilliance. The Radiant Cut allows people to choose an exquisitely shaped rectangular diamond without any compromise. The Original Radiant Cut Diamond Certificate provides the hard data that ensures that each Original Radiant Cut Diamond is cut to the highest standards in the industry.

The Regent Cut diamond shape was born at the Atlass Group in Antwerp, Belgium. A joint venture with Horowitz & Atlass, New York City brings the Regent Cut™ to the U.S. market. The 66-facet Regent Cut™ is based in part on the Regent Diamond, part of the French Crown Jewels that history texts have long declared the world's most perfectly cut diamond. There are 41 facets on the crown and 25 facets on the pavilion of the Regent Cut™. The Regent has been superceded by the "Queen of Hearts" and now The Jubilee Diamond as being the best of all modified square diamond shapes (all produced by Horowitz & Atlass).

Rising Star Cut

The Rising Star was granted a design patent with the U.S. Patent Office in 1992 based on the new technique of achieving its cut; subsequent patents were registered in all diamond polishing countries.. It was the first patented special cut to fully resemble a 5 pointed star. This is a full-depth stone with 56 brilliant facets (a round diamond has 57). The patented cut is sold by millimeter size rather than by carat weight. The diameter is identical to that of a round diamond but weighs less owing to loss in the polishing process. The diamond is usually cut from octahedral rough which is used for cutting round stones.
