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.
