Gemselect is the only seller I trust to buy star gemstones. I bought a star sapphire from them before and was pleased with the purchase. I was disappointed in a star gemstone bought from another site. So, I recommend gemselect.

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.
