One of the most valuable metals on earth is gold. Jewelry represents 50% of the world consumption of gold. Of the remaining, 40% is investments, and 10% is consumed by other industries.
Because of its softness, 24k or “pure” gold, is usually alloyed with base metals for use in jewelry. This alters its hardness and ductility, melting point, color and other properties. Alloys will lower its carat rating, respectively 22k, 18k, 14k or 10k. The lower karats will contain higher percentages of copper or other base metals or silver or palladium in the alloy. Copper is the most commonly used base metal.
Most of gold jewelry product marketed today is manufactured from 18K and 14K gold alloys. With 18K yellow being a little warmer of a color than 14K yellow which tends to be a little lighter and have a brighter finish.
SWISSBACKS earring systems are currently available in 18K and 14K gold. Since gold is the most malleable and ductile of all metals a single gram can be rolled into a one square meter sheet. Our patented mechanism uses a medical grade stainless steel to ensure durability and safety for as long as you own your gold earrings.
