Absolutely love the website, selection and products. Can you guys add a gemstones with inclusions tab. I like those it'd be nice to have them all in one place but i do understand it would be alot of work to go through and categorize them. Thank you anyways

Overall the site is good to use and simple to navigate for what i needed and i liked that they are clear and detailed on the size shape and cut of the stones only input id like is for stones that have a specific refractive quality like moonstone in my case if theyd showcase the cut stones refraction so you know how it looks when buying

I needed a very specific color of tourmaline and Gem Select had it. I had to get the client to agree and then ordered the stone. It arrived better than pictured and we all were very happy.
