I just thought I would share these beauties with you, All natural and verified by my self and another Gemologist. BTW the Black Prince Ruby in the crown Jewels is in fact a red spinel.
The The Swiss Gemmological Institute has a nice article on them http://www.ssef.ch/fileadmin/Documen...rch_Spinel.pdf

Technically they are for sale but i will be very sad to see them go.
