White gold is an alloy of gold and nickel, sliver, or palladium. The inclusion of white metals in the alloy give white gold its silvery color. White gold has a slightly yellowish tint that may be more noticeable depending on the percentage of gold in the metal.
Tungsten (when alloyed with carbide) is also lightweight and is often marketed as being hard to scratch. However, if you are coming in contact with metal or dense, hard surfaces on a regular basis, even Tungsten will eventually show wear and scratches.
Today, it is often alloyed with copper and titanium. It's the only precious metal used in fine jewelry that is 90% to 95% pure, largely hypoallergenic, and tarnish-resistant. Look for platinum jewelry marked 900Pt, 950 Plat, or Plat.
Rose Gold is an alloy that combines gold with copper to create a golden metal with a reddish hue. While it normally uses a gold to copper ratio of 3:1, rose gold can be found with varying percentages of each.
WHITE GOLD - An alloy of yellow gold that contains copper, with nickel, silver, or zinc as a whitening agent.
WISP - A curvy, hair-like feature on a diamond or colored gemstone that can appear as an isolated element or in a cloud-like form.
AlloyCombination of 2 or more metals. AlmandineA type of violet-tinged variety of garnet that ranges in color from deep red to reddish-brown. AlpacaAlpaca (also spelled alpacca) is an alloy consisting of copper, and nickel, zinc, and tin. This metal is a a silver substitute.
A yellowish alloy of copper and zinc, sometimes including small amounts of other metals, but usually made up of 67 percent copper and 33 percent zinc. Brass is generally harder to work with than gold fill or silver, but provides an inexpensive alternative to gold in the yellow metals.
Such minerals either contain the atoms of only one element or else are metal alloys. The native elements are divided into metallic, semimetallic, and nonmetallic subgroups. Metals tend to be dense and malleable substances which possess a characteristic metallic luster and conduct electricity well.
Gold itself does not corrode, but its primary alloys of silver or copper do so - forming very dark chemical compounds - under moist or wet conditions. When a person perspires, fats and fatty acids released can cause corrosion of 14-karat gold, especially when exposed to warmth and air.
The measure for the fineness of gold and gold alloy, expressed as a number, Out of 24 parts by weight, of parts of gold in the alloy, e.g. '24 carat' means pure gold, '14 carat' means 14/24ths gold in the alloy.
Rutile is a major ore of titanium, which is a metal used for high tech alloys. It often forms needle-like crystal inclusions inside quartz. This form of quartz is known as Rutilated Quartz and it looks like small bars of imbedded gold.
To form rolled gold, a silver plate containing gold alloy was placed against copper or copper alloy. The two pieces were heated, typically by rolling, until the silver "sweated" off and the gold bonded chemically to the copper backing.
However, creating gold alloys has another benefit, in that, by choosing the alloying metals carefully, the gold can be imparted with another desirable color. For example, yellow gold is alloyed with an equal mixture of silver and copper, which maintains the yellow color of the gold.
Gold is typically melted down, alloyed with other metals for form jewelry, or bullion. Gold purity is expressed in terms of karat (kt) value, and is a fraction of 24ths. 24 karat gold is 24/24 gold and is pure gold. Gold having a hardness of 2.
