I am a bench jeweler, is part of may business to find company to supply the best quality that I am looking for. I think you are the one for this kind of product. May be a discount to be a retailer will be better but I belive that the merchandise I order came fast and will be covering all my expectation's.

Easiest website to find what I'm looking for as a starter gem collector. Many years in precious metals I decided to expand my interest. This website makes it easy to search exactly what I'm looking for with great description of what I'm purchasing.

I have recently been updating some old jewelry and wanted to add gemstones to some of the pieces. I am amazed at the selection available at GemSelect and found exactly what I was looking for. The prices were very reasonable as well. I would definitely purchase from you again if I am in the market for gemstones again in the future.

The website is very easy to use, easy to find by color, calibrated size, etc. Easy checkout with PayPal (many gem merchants do not accept this payment form). Uses standardized clarity scale, etc.

Gemselect has good prices and many different varieties. I like to collect untreated natural loose gemstones and this is the only website I purchase from. All gemstones are highly detailed about information, state whether they are treated or not, county of origin. I highly recommend them.
