GOLD QUARTZ CAB Ruler is 1/4″ wide (6 mm). U.S. 10 cent coin is 17 mm in diameter. Gemstone weight: 7.78 Grains (Troy) – 2.5 Carats Size: 9.6X3 mm A U.S. ten cent piece (pictured) measures 17 mm in diameter. Having been a placer miner for eighteen years, I had no idea back then what gold ores were supposed to look like. Here’s an all-white quartz containing some of the finest gold available. High-purity gold inside a silicate matrix creates an other-worldly effect. Cab is slightly-rounded across the top, convex on the bottom. Both faces are polished. It’s made from Gympie ore, a highly-sought after variety from Down Under. Two point five carat, round cab measures 9.6 mm by 3 mm wide by 3 mm thick. In the hands of a lapidist, the mineral collaboration between gold and quartz is sometimes transformed into exquisite cabochon. Polished to a luster, it awaits it’s station inside some treasured piece of jewelry. If, perchance, you’ve a special project longing for a new cab, give me a shout. I may be able to fix you up with a custom-made creation shaped and sized to your spec. Like diamonds, gold is precious. In many jewelry settings, gold is the metal of choice used to accompany precious gemstones. Gold is extremely versatile. Relative to other gems, it’s every bit as beautiful, if not more so, than the hard, clear carbon we know as diamonds. ‘Beauty is in the eye of the beholder’. With natural gold quartz, you have silicon dioxide (SiO2) and precious metal occurring together. Add to those superlatives the fact that supply is limited and you’ll understand why I enjoy working with it so much. I suspect if Debeers were in charge of marketing, grade A GQ would cost around $500 per carat. U.S. S&H $4.00 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 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, faults (contact zones), and various other rock formations. This occurs as super-heated, hydrothermal solutions full of silica and metallic elements cool. It was once thought that most precious metal deposits formed beneath the ocean, but in more recent times, it’s been discovered that geothermal hot springs high-above sea level were producing ore bodies of tremendous size all along. Since most gold recovered from these types of lode deposits is micron in size, placer gold is not typically associated with them. Where prominent, fissure-type, auriferous veins exist, however, weathering breaks off richer portions to form gold nuggets, flakes, flour gold, and even finer colloidial ‘free gold’. Vein filling which retains the host 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, California’s Sixteen to One, and yes, even the Gympie Eldorado Gold Mine in Queensland, Australia were mined to great depth. Ore grades rarely remain consistent through the life of a mine. Continual movement within the earth’s crust causes veins to become displaced. This doesn’t happen overnight but over countless millenia. Deep deposits are not only lost but, because of the high cost of mining at great depths, may become unprofitable to mine. In many historic quartz mines, water seepage caused insurmountable problems as well. Within the earth’s crust, considerable geological shifting can occur in ten million years. Veins become discontinuous, disconnected. Many factors influence the availability, production, and profitability of gold quartz. Since only a scant handful of mines around the world produce this rare gemstone, gem-grade GQ remains scare. Even when new high-grade ore deposits are found, collectors and dealers are tasked with procuring something not publicly offered or made available. Oftimes, the best mine run is sent to the mills, so only miners and mine owners ever know anything about the tenor of these ores. Thanks for checking out our digs. Gold of Eldorado 8-19-10
