Hello all. Someone is selling a supposed purple diamond. I was curious and went to see it. The person said it has been in the family for generations. Person was positive it is a diamond, as this is the info their family members were told. Loose stone, said I can perform any test on it. The color in photos look like color of amethyst. The stone was an emerald cut. But I researched and the emerald cut has not changed mostly through time. This one from what I remember, had less facets than today's emerald cuts. Under loupe, very clean stone. No doubling of facets. Does not scratch with tungsten scriber. But weight seems s bit off. Measures 7.98 x 6.14 x 3.92 mm. Weighs 2ct.
