I found what I was looking for...had to look up millimeters to inches. It would be nice to see something, like a quarter, in the pix to show relative size. I plan on buy loose gemstones for every month in the calendar

I trust this company to deliver exactly what is offered. I have never had to return a selection of Gems. I appreciate the company's detailed description of their product. It helps this customer find mounts before the gems arrive. Any day of the year one can find a wide selection of gems, be it by price, color, cut, lot or single. Pricing does not jump all over the place and stays reasonable. Be assured your items will arrive in perfect condition as the company's shipping department does a great job.

I love Gem Select! When you order what you see is what you get. As soon as you make payment that particular gem is taken off the photo album. That way the one you select is a one of that kind.
