Great collection of nine bright and really sparkling Purple Spinels. Assorted rounds and ovals. Average length 6-7mm. Range from 1.00-1.50 carat size. No treatment or heat. You can always sell what you don't want later on EBay! Some have almost clear inclusions mainly on side or underside of stone. These came from a large older parcel, so some do not have perfect edges or cuts, and may have minor surface abrasions (under loupe), but none are dull looking at all! For this price- it's a deal!
