Personal Note From Natural Gems Belgium:
This Ametrine features a stunning combination of light purple and yellow hues, with 80% of the stone being purple and 20% yellow. Its larger size and good to very good cut grade make it a truly eye-catching piece. The symmetry is fair to good, and its luster is vitreous. The polishing is of good quality a well.
