Gold Characteristics and Terms
Gold content is measured in karats, which should not be mistaken with the term carat, used to measure diamond weight. The higher the karat, the greater its gold content and price. The K number is representative of how many parts, by weight, pure gold is contained in 24 parts of the alloy. Therefore, the content of pure gold in the various karats are as follows:
10k = 10/24 = 41.7% pure

India and Gold in the Marketplace
Lately, white gold has become very
fashionable. Because of his, a lot of consumers have opted for the
cool, contemporary white look over the classic yellow look. White
gold has the same properties as yellow gold, but is mixed with
different alloys to give it its white color. Generally, white gold
is created by using a nickel or white gold can be 14k, 18k, or any
karat. Because 14k white gold is 58.3% gold, and 18k white gold is
75% gold, white gold will naturally have a light yellowish tint. In
the final process of manufacturing white gold is rhodium plated to
give it its brilliant white luster. Rhodium is a shiny, white metal,
which is extremely hard and durable. Over time however, the rhodium
plating may wear away, shedding light on the slightly yellowish tint
of the underlying metal. To keep white gold looking its best, it is
recommended that rhodium re-plating occur every 12 to 18 months,
depending on wear.
Yellow gold is gold in its natural shade. By leaps and bounds, yellow gold is the most common type of gold used in jewelry. Yellow gold used for jewelry is usually alloyed with copper and silver to strengthen it. The warm glow of yellow gold works with well with any outfit, any skin or body type and any gemstone. The more yellow a piece is depends on its gold content. Generally, 14 karat gold has a brighter yellow than 10 karat gold; 18 karat gold has a deeper yellow than 14 karat gold, and so on and so forth.
Metal smiths can create gold with a pink, blush like tint by alloying just copper with yellow gold. Experts say mixture lends a soft, flattering effect to the skin.
This alloy is created by mixing silver, copper and zinc to yellow gold. The other types of gold jewelry include gold-filled, gold-plated and vermeil. Gold-filled refers to a layer of gold mechanically bonded to a base (non-precious) metal; the gold content must be at least 1/20th of the total weight of the piece. Gold-plated merchandise has a coating of 10 karat gold or higher applied to a base metal by electrolysis. Vermeil is jewelry that is made by applying a layer of karat gold to a sterling silver base.
The Golden Rules of Care for Your Gold
Proper care for your gold jewelry
is important to maintain its lifelong beauty and value. It is wise
to remove your jewelry during rugged activities. To keep your gold
jewelry clean, soak it in a mild solution of soap and water and
gently scrub it with a soft-bristled brush. Always store your
jewelry separately in a fabric-lined case or in a box with dividers
or separate compartments to avoid scratches or other damage. Be sure
to check any diamond settings periodically for possible damage. If
you see a loose prong, or if the setting looks out of line, bring it
to a professional for inspection right away. The factors that have
increased gold's eternal, universal appeal are numerous: Gold is
extremely rare - It is approximated that all the gold ever mined
would fit underneath the Eiffel Tower in Paris. It takes quite a few
tons of ore to produce just one ounce of gold.
