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

Site worked well and helped me find a rock that matched what I was looking for. Well within budget and I trust it will show up, so that's definitely positive. Not much else to it. Satisfied.
