Always find more niche sizes/shapes as my unconventional designs require from this website. Recommending to fellow designers in the creative atmosphere on the usual, specially due to the quality and certification of gems.

I always enjoy the selection and the unique cuts I can find here. I would love to see more hex cuts tho! Maybe some rose cuts too!
