GOLD MAGNETITE SPECIMEN 3
A stunning ore specimen of Rich Gold Bearing Gold Magnetite Specimen 3. Hefty in weight with the two exceptional metals with exceptional properties. This Gold in Magnetite would make a stunning specimen. This material as a specimen is not common. One of the richest high grade Gold ores found in Australia was The Pinter Lode. The Pinter Lode 70,000 Ounces 1989 – 1991. Includes Gold, Magnetite, Copper and Chlorite. A printed label sticker comes with this specimen.
3.2cm x 3cm x 1.5cm, 25g.
Pinter Lode, White Devil Mine, Tennant Creek, Northern Territory, Australia.
Gold is a pleasure to own and possess, as many people have discovered throughout the ages and around the world. Au 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.
Gold is almost indestructible naturally occurring material. Used and reused for centuries. 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.
Gold has an affinity for tellurium and this is one of the elements that it can bond with easily. Some tellurides are nagyagite, calaverite, sylvanite and krennerite. These are all minor ores of gold. Their contributions to the supply of gold pales next to native gold’s own contribution.
It is easy for people who see shiny golden coloured flakes sparkling 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 then Chalcopyrite, Marcasite and any golden coloured sulfides. Gold specimens are sometimes artistically 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. Good gold crystals are scarce.
Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow Obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen. Magnetite is a natural magnet, hence the name, giving it a very nice distinguishing characteristic. Lodestone was another name for Magnetite. The first compass used Magnetite in a wooden bowl floating on water.
