What it Means: Why does gold come in different colors?

What it Means: Why does gold come in different colors?

In its natural state pure gold is a bright yellow orangish color but is too soft to make jewelry so it is mixed with metal alloys to increase the durability. This alloy to gold ratio affects the karat and the type of alloy affects the color. 24k yellow Gold is the only sort of gold that can be pure. All others are an an amalgamation of gold, and other metals such as copper, and silver. Heres the breakdown on which metals make what colors:

Yellow Gold

Yellow gold's warm hue is usually a creation of pure gold combined with a zinc and copper alloy. The ratio of alloy to gold will affect the brightness of the yellow and the karat. The more alloy the slightly less yellow the gold,  this is why 10k gold (more affordable) is sometimes dipped in a higher karat.
Yellow gold is a personal favorite and our best seller. The color has long been viewed as a sign of wealth and status. For centuries people have decorated themselves with yellow gold jewelry. It's a timeless hue that looks amazing on any skin tone.

White Gold

White gold is an alloy combining pure gold with metals like palladium, nickel, or manganese. These create strength and durability and alter the color but do not completely remove the vibrant yellow from the pure gold. As a result, even a 10k white gold piece, which has the least amount of gold, will still have a slight yellow hue. For this reason, white gold jewelry is typically coated in rhodium to create the slivery hue you commonly see. Once plated there is no visible difference in 10k, 14k or 18k white gold. Over time, the plating will wear off and the jewelry can be re-plated or worn as is, whichever is your preference. If you prefer to re-plate CaWren Concierge can assist you.  

Rose Gold

Rose gold's noticeable pink hue comes from combining a copper alloy with gold. The more copper used, the redder the gold appears. Unlike yellow gold which loses its yellow color as the karat decreases, a 10k rose gold ring would appear slightly brighter than a 18k rose gold due to the higher copper contents. Rose gold regained popularity recently and we're not mad at it.

Black Gold

Not really a new trend, but certainly less common, black gold is made from real gold just like rose and white. Typically, yellow gold is plated with black rhodium mixed with other metals like cobalt to create a rich, dark finish. While we don't get many request for black gold it is available for custom orders.
