Gem select has a great selection of Gems, very defined pictures of item and easy process to filter down selection including, gem, color, type, size and weight.
I had a limited budget and wanted a star ruby. GemSelect offered small, but pretty stones at a very reasonable price. I've always been satisfied with my GemSelect purchases, although there are also eBay vendors I use for less expensive gems. Their selection of more expensive stones, like rubies, is very limited, however.
I decided recently to start a gemstone collection! I searched online for a reputable gem merchant and found gem select! Their selection is gorgeous and I’m excited to receive my first package! Checkout was a breeze!
