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.

Site is easy to navigate and the variety is great and how often new products are added is also great.

My experience has always been fantastic. Today I saved 6 gems to email a customer looking for a particular color blend to fit into an east west setting, so her options were limited, but we found one she wanted, deleted all the others in the cart and order the gem she selected. It was helpful to be able to put them in the cart so I could save them until she selected the one she wanted without having to research all of them again.

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

I've purchased from here many times over the last decade+. I find the information easy to understand, helpful, and interesting. I have always been satisfied that I got exactly what I ordered. Pictures and descriptions are clear and unique to each stone.
