The gemstone location dataset contains information on gemstone deposits and mining throughout the world. It includes following gemstones: ruby, sapphire, emerald, aquamarine, heliodor, moganite, goshenite, nephrite, jadeite, lapis lazuli, opal, tourmaline, periodit, topaz, pearl, garnet, zircon, spinel, amber, and quartz. It excludes diamonds, which are included in the diamond deposit dataset, DIADATA.
The GEMDATA dataset consists of 1022 gemstone sites in 61 countries. The individual gemstone sites are represented as points in the dataset (and on a map). Each site is accompanied by latitude and longitude coordinates and information on the type of gemstone found on the site, discovery date, and when relevant, information on the first production date.
