Gold Mineral Data

What is the transparency of gold?

Experiments have resulted in gold films with a theoretically expected transparency of over 80% in the visible range. Gold films, made suitably thin, can exhibit high transparency and high conductivity at the same time.

What is the average crystal size of gold?

The size of gold crystals varies from colloidal (< 0.1 microns) up to several cm, usually around a fraction of mm.

What happens to a crystal when it cleavages?

Two separate pressures pushed toward the center of a crystal after its formation, causing the crystal interior to evenly dislodge on a flat, smooth plane. Twinned crystals that separated from one another, leaving a flat, smooth plane. With enough perception, a distinction can be made between parting and cleavage.

What happens to the specific gravity of gold?

Specific gravity decreases as gold naturally alloys with silver, copper or other metals. Color, hardness, streak, specific gravity, ductility, malleability. Many uses in jewelry, coinage, and bullion.

What kind of metals are in a gold nugget?

Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is.

What are the properties of alluvial gold particles?

They have the uniform color and rounded edges common of alluvial gold particles. What is Gold? Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties – some of which are unique to gold. No other element has more uses than gold.
