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.

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