Electrum is a naturally occurring alloy of gold and silver, with trace amounts of copper and other metals. Colour ranges from pale to bright yellow, depending on the proportions of gold and silver.

Electrum
In antiquarian times, a pale yellow alloy of gold containing about 15-45% of silver but also used in the mid 19th century to cover a copper-26% nickel-23% zinc (high nickel-silver type) alloy. Electum is from the Greek word for amber.

The percentage of gold naturally varies, according to the amount of other metal used. White gold is highly reflective and not subject to tarnish. The ancient term for it was Electrum. Its use predates that of Palladium and Platinum.

It occurs as a pure free metal (native silver) and alloyed with gold (electrum), as well as in various minerals, such as argentite and chlorargyrite. Most silver is produced as a by-product of copper, gold, lead, and zinc mining.

Amber was the most favored stone, set in silver, gold or moonlight tinted gold called "electrum". Their granular gold work was as fine as the Phoenicians, but lost its popularity with the influx of Greek filigree.

Native gold contains usually eight to ten percent silver, but often much more - alloys with a silver content over 20% are called electrum. As the amount of silver increases, the color becomes whiter and the specific gravity becomes lower.
