Overall Rating -> 10 star ratings

The website design looks dated and not particularly up to date with what you would expect from a site selling gemstones - however the product information is clearly laid out and well marked, with details for each product sold.

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc

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.

I searched for the size, dimensions and quality of the stones I was looking for and then compared and ordered.
