All items were delivered on time with all items meeting or exceeding my expectations. Cut, clarity and color were very close to the photos and description.

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!
