Pure Black Spinel from Bo Phloi, Kanchanaburi Province, Thailand⁠
⁠
We recently stumbled upon this hoard that was overstock from a product line for a major European jewelry house ⁠
⁠
Buying in bulk is a great way to try this material out without committing to a larger parcel 
⁠
Black Spinel has incredible luster and durability . We're including a couple photos of gemstones we had faceted for Gem Dragon Auctions. They're quite popular 

Sizes average around a gram. Some slightly less, some slightly more than a gram

Only $2 per gram!
⁠5 gram minimum purchase
