Lapidary Journal Jewelry Artist's 2013 Gemstone Price Index
If gemstones (transparent , translucent, and opaque; faceted, cabochons, and gem rough) are on your Tucson (or any) shopping list, Lapidary Journal Jewelry Artist's annual Gemstone Price Index is a handy tool you won't want to miss. Download it, save it, print it, and take it with you to all the gem shows this year–and you'll be better informed when it comes time to buy.
"The Gemstone Price Index is limited to gem rough available to amateurs and semi-professional cutters at shows, on the Internet, and from wholesalers," writes Sharon Elaine Thompson, GG, FGA, who compiled the list. "For this reason it does not include rough such as emerald, ruby, exceptional quality blue sapphire, or Imperial topaz, materials that are not readily available except to professionals." it does include dozens of transparent faceted gems and faceting rough from almandine garnet to tsavorite and many in between, as well as gems from aventurine to variscite in translucent to opaque cabochons and cabbing/carving rough (all in commercial and gem grades).
