Velvety Appearance:
This gemstone exhibits an appearance that is classified as "velvety". Such an appearance results from very fine microscopic particles that scatter light, causing the coveted visual effect without negatively affecting the gem's transparency. Gemstones with a velvety appearance have little to no extinction, display a warm glow, and look very pleasing to the eye. Therefore, velvety appearance is considered a highly sought-after trait in gemstones. The most prominent examples of gemstones coveted for their velvety appearance are the legendary Kashmir sapphires.
|
|
Superior Cutting:
The cut grade of this gemstone is classified as "superior". It has been masterfully cut by our highly skilled gem cutters (lapidaries) to bring out its best qualities and diminish any perceived imperfections. This gemstone is symmetrical, well-proportioned, and has an excellent surface polish. Therefore, it displays the maximum dispersion, scintillation, and fire.
|
|
Vibrant Brilliancy:
This gemstone exhibits a brilliancy that is classified as "vibrant." Vibrant brilliancy results from a combination of factors such as skillful cutting, excellent clarity, even color distribution, and a very low degree of extinction.
