Sentences with phrase «optical symmetry»

By analyzing the precision and consistency of the hearts within the «hearts and arrows» pattern, we're able to assess the optical symmetry of the diamond as a whole.

This superior level of optical symmetry results in a higher volume of light return, brighter looking diamonds, and a higher degree of brilliance, dispersion, and scintillation than provided by standard ideal cut diamonds.

Hearts images are used to judge the optical symmetry of a diamond.

Bringing the world a diamond that features the highest degree of optical symmetry, master diamond cutter Brian Gavin has once again delivered a truly distinctive diamond design — one that features the exacting balance required to produce a perfect hearts and arrows pattern.

Brian Gavin Blue Diamonds: The diamonds featured in the Brian Gavin Blue collection of diamonds with blue fluorescence, exhibit a high degree of optical symmetry, and have been graded as AGS Ideal for Light Performance by the American Gem Society Laboratory.

When a diamond is called super ideal, it must have two things: 1) perfect proportions for maximum fire and brilliance, and 2) precise optical symmetry.

This means that the diamond has precise optical symmetry.

Brian Gavin's brand is built upon the concept of ideal cut diamonds, with maximum light performance and optical symmetry.

When you see a diamond with well - defined and completely symmetrical hearts and arrows, it means that each facet is perfectly aligned and the diamond has perfect optical symmetry.
