The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.

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!
