Cut by some of the world's foremost diamond cutters, this exclusive collection is demonstrably among the finest of diamonds available with distinctive faceting, a high degree of dispersion, incredible scintillation and remarkable brilliance. Ben Bridge Jeweler believes the Ben Bridge Signature Diamond™ to be the "most beautiful" we've ever offered in our over 100 year history.
All Ben Bridge Signature Diamonds™ one-half carat and larger have laboratory reports from the Gemological Institute of America (GIA) and the diamond is laser inscribed on the girdle edge with the GIA laboratory report number for your assurance and verification.
ASET® (Angular Spectrum Evaluation Tool)
The ASET® is a tool (created by the American Gem Society) that we use in judging the light performance of the diamond. Light performance is determined by the cut of the diamond (see our section on the 4 C’s of diamonds for more information). The return of light is represented by four different colors; red, green, blue and black.
Red is the most desirable. Red represents light that travels through the diamond unobstructed and with full intensity. This is the light that makes the diamond bright and brilliant.
Green represents the less efficient light. It can reflect off objects or it might enter the diamond at indirect angles. This light may contribute slightly to contrast, but for the most part is undesirable.
Blue represents “contrast”. It is the “texture” or pattern of light and dark areas that our eye finds pleasing. It is caused by light that could have entered the diamond, but is blocked by the viewer’s head. It should be distributed in a symmetrical pattern.
Black (and occasionally white) represents “leakage” which is an area from which light literally leaks out of the diamond and is lost. Leakage is less desirable and in all cases should be minimal.
These are images of a Ben Bridge Signature Diamond™ when viewed under with ASET® device. The Ben Bridge Signature Diamond™ exhibits extraordinary intense return of light as shown in these images.
“It was a treat looking at your Ben Bridge Signature cut. I knew before I viewed the diamond in the ASET® that it would show lots of red because of how bright it was…I was right! Red is significant because it reveals areas of the diamond that gather light directly from the source where it is most intense.” –Jim Caudill, Creator of the ASET
