Abstract
During 2005, the estimated value of natural gemstones produced from US deposits was $13.9 million. Production included agates, amber, beryl, coral, garnet, jade, jasper, opal, pearl, quartz, sapphire, shell, topaz, tourmaline, and torquoise among others. For the year, the US gemstone trade with all countries and territories exceeded $26 billion. There are indication that there may be continued growth in the US diamond and jewelry markets in 2006.
