Gold has an extraordinary heritage with unique qualities. It is resistant to rust, tarnish, and corrosion. Although gold is very strong, it’s also the most malleable of all precious metals.
Pure gold is too soft for everyday wear, so it is alloyed with a mixture of metals like silver, copper, nickel, and zinc to give it strength and durability. Karatage, denoted by a number followed by “k” indicates purity, or how much of the metal in a piece of jewelry is gold. Karatage is expressed in 24ths, making 24k gold, 100% gold.
The color of gold is determined by two factors:
- The type of metal alloys included
- The percentage of each metal alloy
Natural gold and color-saturated alloys are what give yellow gold jewelry its rich shine. The alloys most commonly used, are copper with a red hue, and silver featuring a green hue. An expert mixture of copper, silver and pure gold gives this precious metal its signature warmth.
A silvery white character is what makes white gold jewelry so appealing. In order to make the gold white, it is combined with metal alloys that are white in nature and plated with an extremely hard element called rhodium. Although strong, rhodium may wear away over time. Replating is a simple process that can be done to restore whiteness to your jewelry.
White Gold With Black Rhodium:
Black rhodium is plated to white gold creating a rich black appearance that is extremely hard and strong. As with traditional white rhodium, black rhodium may wear away over time.
The beautiful pink hue of rose gold jewelry is created by using a copper alloy. Again, the overall percentages of metal alloys is the same for rose gold as it is for yellow or white, there is just a different mixture in what alloys are used.
Rich in golden color, many of our fine jewelry pieces are crafted with vermeil. The industry standard definition of vermeil is sterling silver that is plated with 10k gold with a minimum of 2.5 microns in thickness for long wearing durability.
