Brian Kosnar offers collector quality mineral specimens and gemstones from world wide localities
The goal of this site is to present a comprehensive list of links to mineral dealer websites, and sites for businesses that offer related services. That includes some gem, beads, crafts and related businesses, particularly if they offer specimens for sale.
The listings on this site are checked regularly for broken links, insecure sites or sites with illegal or objectionable content, irrelevant content, slow-loading sites or sites that time out.

Update May 16, 2025: several dozen broken links were removed. The site has zero broken links, as of today.
