Here is a fantastic and historic NATIVE GOLD CRYSTAL from the IBEX MINE, in LEADVILLE, COLORADO. This is a showy, elegant specimen of exceptionally well crystallized gold. Imagine the excitement the miner must have experienced when he found this in the mine... crystallized gold is considered one of the rarest forms of gold in the world, and SHARP CRYSTALS like this one are ESPECIALLY TREASURED BY COLLECTORS.
We are occasionally asked why the prices for our crystallized gold are higher than the spot price of gold. There are several reasons. First is that the market price is for bullion in dust or bars, so gold crystals always trade for a much higher price. Next, knowing the specific locality where a specimen is found increases the value compared to a gold specimen with no provenance. Finally, some gold localities are more desirable than others, depending on whether the locality is still producing or not and/or the age of the specimen (if known).
Gold is a pleasure to own and possess, as many people have discovered throughout the ages and around the world. Gold is a very stubborn element when it comes to reacting to or combining with other elements. Keeping this in mind, helps to explain many things about gold. There are very few true gold ores, besides native gold, because it forms a major part of only a few rare minerals, it is found as little more than a trace in a few others or it is alloyed to a small extent with other metals such as silver. Gold is almost indestructible and has been used and then reused for centuries to the extent that all gold of known existence is almost equal to all the gold that has ever been mined. Gold is a great medium metal for jewelry, as it never tarnishes. Native gold wires emerging from massive white quartz can make for a visually stunning specimen.
A few of the minerals that bear gold in their respective formulas are in a subclass of sulfides called the tellurides. The element gold seems to have an affinity for tellurium and this is one of the only elements that gold can bond with easily. In fact only a few rare tellurides are found with out gold. A few of the tellurides are nagyagite, calaverite, sylvanite and krennerite. These are all minor ores of gold but their contributions to the supply of gold pales next to native gold's own contribution. Occassionally these minerals are associated with native gold.
There are a number of minerals that are aptly named "Fool's Gold" because only a fool could believe they are gold! Actually it is easy for people who see shiny golden colored flakes sparkling at them from some rock they just picked up to believe that they have struck pay-dirt. Gold's ductility, sectility, density and softness are usually sufficient to distinguish it from the much cheaper imposters. The most famous "fool's gold" is the very common sulfide, pyrite. Chalcopyrite, marcasite and just about any golden colored sulfide has been also proven to be worthy the "fool's gold" monicure. Weathered flakes of biotite which can sport a bright yellow color and a nice flash of light when viewed just right, have also been mistaken for gold.
Gold specimens are sometimes artisticly stunning and a good investment as well. After all, it is gold, which never seems to lose its value. Good natural specimens though are more expensive than their actual weight value. This is to be expected as good gold crystals are somewhat scarce (most are melted down for quick profits) and you really don't want a natural specimen to be worth what a lump of previously smelted and refined gold is worth, do you? |
