All items were delivered on time with all items meeting or exceeding my expectations. Cut, clarity and color were very close to the photos and description.

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.
