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.

The process was pleasant, I chose to purchase the stone traditional to the month of March as it is the month in which I was born.

I do enjoy this website and the wide selection. I would like to see more untreated stones. I also wasn't able to see my past order when I logged in.
