AUSTRALIA GOLD QUARTZ CABOCHON 11.2 CARATS NATURAL GOLD QUARTZ

Description: GOLD QUARTZ CABOCHON from AUSTRALIA Ruler is 1/4" wide (6 mm). U.S. 10 cent coin is 17 mm in diameter. Gemstone weight: 34.9 Grains (Troy) - 11.2 Carats Size: 15X4.5 mm A U.S. ten cent piece (pictured) measures 17 mm in diameter. Having been a placer miner for eighteen years, I had no clue what gold ores were supposed to look like. Here's just one more example - an exotic, collector stone from Down Under. This is most likely the last cab I will ever fashion from such quartz as this. It veritebly bristles with particles of high-purity gold throughout. Until someone finds more, it's unlikely you'll be seeing rock like this again. It's certainly priced to sell. Two faces are pictured, both the 'show' face and the flat back. Gems like this aren't created in a factory, they're cut from natural gold ore. Such gemstone as this is beyond rare. U.S. S&H $8.00 via priority box. Combined shipping offered. If you plan on buying more than one item from Gold of Eldorado, please request an invoice from me at checkout time. Check any and all Gold of Eldorado feedback for disputes arising from non-authenticity of the specimens I sell. All of my advertised specimens, slabs, cabochons, gold ores et al are comprised of naturally-occurring minerals (not man-made). These will contain visible native gold and/or are composed almost entirely of gold (i.e. gold nuggets, gold flakes, wire gold specimens). This is the real deal...natural gold in quartz as God and nature worked it out over the millennium.

For those of you unfamiliar with this product, GQ is, essentially, gold ore, very high-grade gold ore found in the outer crust of the earth. When geological conditions are just right, metallic gold-crystals lithify (harden), along with quartz, in fissure-type veins, in altered faults (contact zones) and various other rock formations. This occurs as boiling hot, hydrothermal solutions full of silica and metal cool. It was once thought that most precious metal deposits formed beneath the ocean, but in more recent times, it was discovered that geothermal hot springs well-above sea level have been producing ore bodies of tremendous size. Since most of the gold recovered from these types of deposits is micron in size, placer deposits are not typically associated with such lodes. Where prominent, gold-bearing, fissure-type veins exist, however, erosion weathers richer portions of these ore bodies to form gold nuggets, gold flakes, flour gold, and even finer 'free gold'. Vein filling which retains the host matrix rock (gangue) and harbors metalliferous gold can become one of the earth's more highly-prized gemstones. The ideal criteria for this gemstone type are hardness, color, and richness. The best grades of gem rock are very hard, unbrecciated, and contain minimal cracks or fissures. Cryptocrystalline quartz/gold, where it exists, is highly-prized by gemologists/lapidaries/jewelers/and collectors. Overall mineral compositions and characteristics of gold-bearing stone found in fissure veins (and larger ore bodies) vary from one deposit to the next. This results in the formation of differently-colored matrix (host rock). The gemstone offered here is just one more example. The metallic mineral, gold, occurs in a variety of geological formations. In modern-day mining enterprises, entire mountains are blasted down, transported and piled into heaps, then soaked with cyanide to leach the precious metal from the ore. A century ago, it was much more likely that prospectors would sink a vertical shaft on top of an ore outcropping or attempt to follow a horizontal or diagonal lead/ledge/lens/vein into a mountainside. Once extracted from the mine-shaft, recovering the gold locked inside the ore was very labor intensive. Arrastras were one of the earlier crushing devices used for pulverizing and removing gold from such ore. Stamp mills, even more labor-intensive albeit more productive, soon followed. An old time prospector's first inkling of a lode occurrence would more than likely have been the discovery of a quartz vein. A rich placer deposit holding coarse, gnarly, even crystalline gold along with gangue would have been a very strong indicator for the presence of a vein system close by. Quartz veins, at one time, were notoriously famous producers of gold, but many of these prominent, fissure-type, lode deposits such as the Homestake Mine in South Dakota and California's Sixteen to One were mined to great depth. Since ore grades rarely remain consistently uniform throughout the life of a mine and veins shift displaced as they are by the continual movement of the earth's crust, deep deposits, at some point, may be lost or simply become unprofitable to mine. Water seepage was often a major problem in many of the historic old mines of the western U.S. Sometimes, a productive vein decides to relocate. It doesn't do this overnight, but, as a result of ancient geological shifting in the earth's crust, the vein may have slipped sideways to another location and, in that manner, is lost. Prices for metals fluctuate dramatically. A great many factors influence the availability, production, and profitability of gold quartz gemstone. GQ appears to be extremely scare at this time since only a scant handful of mines around the world are producing this rare gemstone material. Even when a new high-grade ore deposit is discovered, collectors and dealers are tasked with procuring something not being publicly offered or made available. I am making this available.
