Personal Note From Natural Gems Belgium:
Natural chatoyance phenomenal chrysoberyl is extremely rare, seldom seen in jewelry stores, and most jewelry shoppers have never heard of it. If you are interested in chrysoberyl jewelry, you might find it at a store owned by a jewelry designer who specializes in rare and seldom-seen gems. prices per carat can go higher the diamonds per ct.
Where standard cat eye chrysoberyls display two colors in direct line next to the chaoyance laser, this gemstone is differently displaying colors, making it more unique and more rare, the Perfect Laser Cat's Eye is very distinct and visible under flashlight.
Color grade is unique, polish is good, and symmetry is good.
