GemSelect is always my first choice for purchasing gemstones. The fact that the gems are always exactly as described and pictured on the website has earned my trust many times over. Even when I don't buy, I still love browsing all the beautiful stones. My new favorites are the bright green Tsavorites!

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
