I have found what I think is the best kept secret for buying stones, and I have to tell you about this gem stone site I found! There is a large selection of stones and crystals, and the best prices I have found for nuummite! They make it incredibly easy to find exactly what you are looking for by shape, size, cost, and clarity. I have already purchased two stones and I will be checking the site frequently from now on for everything and anything that I am hoping to find. They have individual pictures of every stone with different views so you absolutely know what you are buying.Honestly, I was hesitant to purchase something the first time BECAUSE the prices were so competitive and below anything I found elsewhere and because the stone was both being purchased online and from another country. I received the stone ahead of shipping schedule and when I received the package, it was in not one but two separate zip lock bags. One had the certificate of authenticity and details about the stone. The second had information about the stone itself. I was so impressed with the quality of the stone and that it was definitely the stone I picked out on their site, that I ordered another stone without hesitation. I will be using this site to purchase gifts for everyone I can think of! lol

The selection is great, but the quality pictures does the selling. I know what I've ordered before I get the product in the mail.
