I am never let down by GemSelect. I love that you get the exact stone you want. Shipping is always in a few days. I have spread the word about GemSelect on social media jewelry creating groups that I attend. This sapphire is going to make one gorgeous ring

I was looking for a site with every type of gem I could want for setting in luxury blades and assumed I would need to look outside the US, but GemSelect made it easy to get everything I wanted without leaving the house! Wide enough selection that I do not feel the need to look elsewhere and pricing the same.
