From the frozen tundra of Canada’s Northwest Territories, we proudly present The Ikuma™ Diamond Collection by Ben Bridge Jeweler.

Through a fascinating story of discovery, perseverance and environmental sensitivity, the Ikuma™ diamond is now available exclusively at Ben Bridge Jeweler.

Formed deep in the underground more than a billion years ago by the mysterious forces of nature, the Ikuma™ diamond was thrust closer to the earth’s surface by powerful volcanic eruptions. In 1991, after years of exploration, traces of these diamonds were discovered in the remote barren land of Canada’s Northwest Territories.

Following discovery and excavation, the diamonds are cut and polished in a state-of-the-art facility in Canada to the exacting standards of Ben Bridge.

The Ikuma™ Princess by Ben Bridge

Master artisans have created this unique 85 facet, princess cut diamond to maximize fire, scintillation and brilliance.

As light enters the diamond, the precisely positioned facets act as mirrors to reflect light in a spectacular blaze of color and beauty.

All Ikuma™ diamonds one-third carat and larger are independently graded by the American Gem Society and laser inscribed on the girdle edge with the individual laboratory report number for your assurance of quality and verification of origin.

The Ikuma™ Ideal by Ben Bridge

The pinnacle of The Ikuma™ Diamond Collection- The Ikuma™ Ideal Diamond is cut to exacting proportions based on the mathematical calculations of Marcel Tolkowsky in 1919.

This ideal cut was created with ideal polish, symmetry and proportions to produce maximum brilliance with a high degree of dispersion or “fire”, and is documented as such by the American Gem Society.

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 Ikuma™ diamond when viewed under with ASET® device. The Ben Bridge Ikuma™ diamond exhibits extraordinary intense return of light as shown in these images.
