Apatite from Merelani Hills, Arusha, Tanzania [db_pics/pics/mk681b.jpg]

Apatite from Merelani Hills, Arusha, Tanzania [db_pics/pics/mk681c.jpg]

Single blue Apatite crystal of exceptional size and quality from the Merelani Tanzanite mines. This is a complete, gem quality crystal with a steep, multi-faceted termination. There are a couple edge chips, but it is in overall excellent condition and one of the better I've seen from the locality. This is likely from the Karo Mine where the best Apatite were found years ago. This is an excellent crystal and the pictures don't do it justice. (click on a page number to go to that page:)
