Although the stones are smaller than I thought, I really don't think in millimeters, they are perfect. I plan to put one into a ring and the other into a necklace. Ordering was easy, contact kept me aware of how shipping was going, and delivery was sooner than expected. The quality of stones I have ordered in the past and this recent order is outstanding and stones I will be proud to wear.

I visited several online loose stone shops trying to find rare stones. I finally found one that I've been looking for here, and very satisfied. Looking forward to receive the item in 3 weeks.
