Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

Always find more niche sizes/shapes as my unconventional designs require from this website. Recommending to fellow designers in the creative atmosphere on the usual, specially due to the quality and certification of gems.
