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.

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.
