Personal Note From Natural Gems Belgium:
this 1.86 ct natural unheated ruy is a purplish red gemstone with cut grade good, symmetry fair to good, polish good, and good to very good vitreous luster. It has a tiny chip only visible to the very careful observer, that is of no influence for quality in setting.
