I love looking at gems. Your site is very easy to navigate and to find what I'm looking for. It is also very easy to explore lesser-known gems that are not always easily found. I spend way too much time exploring! LOL

It's important to understand what you are buying. Gem stones all vary significantly and you need to adjust your selection based on purpose, cost, expected out come.In my case I was selecting and very attractive heart shaped stone which once set in a pendent would fall in a specific cost range yet present an attractive picture of luxury without extreme risk e.g loss.

I have purchased several times from GemSelect and am always pleased with the stones. The information on the site about each stone is thorough. I don't have to worry about fake stones from them and the prices are quite reasonable. I love the new cards provided for each stone. I would highly recommend them.
