NATIVE GOLD QUARTZ SPECIMEN from the MOTHER LODE. R uler is 1/4 wide (6 mm). 10 cent coin is 17 mm in diameter. S pecimen weight: 1.3 G ram - 20.3 G rains (Troy).
S ize: 15.1X8.3X7.3 mm. I f you've an eye for gold straight from the earth, check out this Au-filled chunk from the Sierra Nevada Mtns.
Welcome to the two thousand teens, the digital world, and age of'cheap' specimens. Half of this rock really beams with the yellowest gold you could imagine.
Two other mineral types can be seen associated. One is a dark green chloritized mineral and the other appears in the form of cubic pyrite. Very cool and interesting specimen from an unknown location. It takes a lot of effort to find gold whether it's placer or a pocket, so there's really no such thing as an'ugly nugget'. Each one is beautiful in it's own way.I guarantee the gold growths here are a natural occurrence. All my specimens show visible gold and are authentic gold quartz specimens. I don't paste'pounded gold' or spray gold-colored paint on barren rock.
Refractory ores, which need to be heated and run through special processes to release the minute amount of gold locked up inside, aren't usually my thing. When I do sell sulphides, you'll be able to see gold associated with the pyrites. You won't need to crush and treat my rocks with cyanide solution to get at the gold. We're not dealing in micron gold. I deal in genuine high-grade, naturally-occurring gold quartz with visible gold, both as specimen and as jewelry-grade slab.Such rich rocks and lapidary rough are hard to find and expensive to obtain. I poured through old mining dumps for years looking at orange-yellow-rusty rock through a loupe, but I never found a piece with visible gold. Hydrothermal solutions carrying gold and silica crystallized into veins of gold quartz. This specimen comes from one of the many vein systems sourcing the immense placer deposits of the Sierra Nevada Mtns, the famed Mother Lode.
15.43 GRAINS = 1 GRAM. 31.103 GRAMS = 1 TROY OUNCE. 24 GRAINS = 1 PENNYWEIGHT (DWT).
20 DWT = 1 TROY OUNCE. 480 GRAINS = 1 TROY OUNCE. We leave no stones unturned insuring our customers get what they bargained for. If you're not satisfied with this item, contact me.
One method used for mining'free gold' in the desert is a device (some think of it as an instrument of torture) better known as a drywasher. Some refer to it as an'air jig'. A bellows-type machine might be called a'puffer belly'. The other main type of drywasher doesn't'puff', however, it blows.There was a time when my preferred method of mining was dry-washing. Each method has it's own fans and differing applications.
While metal detecting allows a person to cover much larger areas during the course of a day's prospecting, dry-washing allows users to more-completely test alluvium for gold since it conceivably facilitates the recovery of both fines and nuggets. There are instances where gold found at a site may pay handsomely, but the particles themselves aren't large enough to register on a metal detector. Those detractors of the methodology don't fully understand it's many applications in the nuanced world of dry-washing. To use a drywasher, first, you determine if the material you wish to run is dry and loose enough to be processed with any degree of efficiency.
Even when it's completely dry, you wouldn't think hard-packed clay or caliche could be run through a drywasher, but surprisingly, once these consolidated sediments are broken up out of beds or packs, most of the bigger gold pieces can actually be separated from the dirt. Extremely wet ground poses a problem.It needs to be spread out in the sun for drying. The acts of screening or running material through your drywasher will also help to accomplish the same purpose. Ideally, the rule is: the dryer, the better. It's not always a lost cause, however, when the ground seems too hard-packed or wet to run. If a spot looks favorable, set your drywasher up and stabilize it. Then, start conveying the dirt, clay, sand, or gravel (by shovel or bucket) onto the screening section of your machine (the grizzly).
Sediments classified by the grizzly drop into another section of the apparatus known as the'hopper'. Ideally, o nce the machine is activated, the down-sized material feeds over a series of "riffles" in a concentrator tray. This process varies slightly from machine to machine.
Principally gold (if there is any) and fine-grained black sands (assorted iron minerals) are separated from the paydirt in this manner and become concentrate. Panning, or the use of some other final cleanup method, comes afterwards. Thanks for checking out our digs. G old of E ldorado 1-14-13.
