My Favorite Links

1. gemselect.com

They have lots of valuable information, and disclose all relevant data about their stones.  It's how it should be done if one sells over the internet.  Prices are in the wholesale range, but on the high end.  That's expected for an online dealer - photographing and listing stones is a lot of work.

2. wildfishgems.com

Love their gems!  Cool stories.  High prices but justified in my view.
