Gold’s inherent beauty imprints upon our lives in a myriad of quiet ways - the tear-smudged cheek of a Klimt; the fragile whisper of spun sugar threads; the brash stripes of a fat-bellied bee.

 

However, when we find ourselves enchanted by an amazing piece of antique jewelry, gold assails our senses with all the boldness of a sassy midcentury cocktail ring, the brilliance of a Victorian locket, or the blush of warm-hued Edwardian bracelet.
 

So, why does some gold jewelry sizzle brightly, while other pieces reflect a rosy, pink hue? Why is some gold more resilient, and some gold softer?

 

Let’s look further….

 

The Karat Weights

Gold is weighed in karats. 24 karats constitutes pure gold, and anything less than that is an alloy of gold and other metals.

 

24 Karat 

100% gold.

Soft and delicate, pure gold must be handled with care.

Every time you wear your 24KT jewelry, particles are lost.

 

22 Karat

91.6% gold.

Still soft, 22 karat gold will wear thin from everyday use. 22 karat gold tends toward a yellow shine, but the degree of brightness depends on whether the other two karats are silver or copper.

 

As you can imagine, adding copper, makes for a rosier glow.

 

18 Karat

75% gold.

18 karat gold’s strength makes it more popular for creating jewelry.

 

Most rose gold is 18 karat (75% gold, 21% copper, 4% silver), deriving its warm hue from the large percentage of copper.

 

14 Karat

53.8% gold. Also popular for creating jewelry.

 

9 Karat

37.5% gold.

9 karat gold will flush rose or dull bronze if the remaining alloy is copper; on the other hand, the color is considered white if the alloy is silver or nickel.

 

European 9 karat white gold was (and is) made with silver as nickel was determined to cause skin problems.

 

 The Colors

Yellow Gold

An alloy of pure gold and a small percentage of silver, copper or zinc.

 

White Gold

An alloy of pure gold and either silver or palladium.

 

Rose Gold

An alloy of pure gold and copper.
 

The Alternatives

Gold Plate

A very thin layer of precious metal electroplated to an inexpensive base metal. Gold plate wears off quickly to expose the base metal; no measurable proportion of gold is required.

 

Gold Fill

A layer of gold bonded to both sides of a metal, typically brass. Gold fill is required to contain 5% gold by weight.
