Great site for finding specific stones and sizes for individual pieces of jewelry

This is the first time I have used this site. I was dissatisfied with the quality of gems and supplies elsewhere and decided to try GemSelect. They are awesome! I was thrilled to see the variety and the great web performance. There was the ability to search for information as well as gems. Things like the clarity rating system and caret weight of the gems. I have always loved making things and I have just started to make jewelry as a business. However I have never made a ring before and have always wanted to. On GemSelect I was able to find good quality gems to use in my creations. I am so glad the website is so easy to use. Thank you GemSelect.

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!
