Vargas Gem & Mineral CollectionA searchable database of photographs and information about the minerals, gems and gemstones of the collection, over 6300 in all, and information about the collection and the Vargases are accessible here. Gem and mineral specimens, comprising over 3700 single crystals, twinned crystals, crystal clusters and crystal intergrowths, are searchable by mineral and varietal name, color, and crystal shape/habit. The 2600+ Gemstones of the collection, both faceted and in cabachon, can also be searched by mineral/variety name and color, as well as by the type and pattern of cut. Specimens are also grouped into searchable sub-collections. These include mineral psuedomorphs, quartz with inclusions, twinned crystals, synthetic gems, a “thumbnail” collection, and quartz gemstones cut to demonstrate the patterns in three Vargas books on faceting diagrams.
