White gold

White gold is a popular alloy used in jewelry that has a silvery-white appearance, resembling the look of platinum. It is typically made by combining gold with one or more white metals, such as nickel, palladium, or silver. The addition of these white metals gives gold a whiter color compared to its natural yellow state.

.

The most common alloy used for white gold is a combination of gold with nickel or palladium. Additionally, rhodium, a shiny, reflective metal, is often plated onto white gold jewelry to enhance its appearance and provide extra durability. Rhodium plating gives white gold a bright, reflective surface and helps protect the underlying metal from scratches and tarnish.

.

White gold and rhodium plating are not friends

.

It’s important to note that the natural color of gold is yellow, and the term “white gold” refers to the color achieved through alloying rather than the existence of a naturally occurring white gold. The specific alloy composition can vary, and the choice of metals depends on factors such as desired color, durability, and any potential allergies or sensitivities.

.

Consumers should be aware that rhodium plating on white gold jewelry may wear off over time, revealing the underlying metal’s true color. Periodic re-plating may be necessary to maintain the bright white appearance. Additionally, some people may be allergic to nickel, so nickel-free white gold alloys are available to address this concern.

.

Hardness of white gold

.

The hardness of white gold can be higher than regular gold due to the alloying metals. It often is ranging from about 150 to 250 HV, depending on the specific composition while 18k or 14k gold does 120 to 200 HV.

.

Compare case materials on the Hardness Vickers scale (from hard to hardest):

.

Carbon 20-50 HV
Platinum 40 HV (950 platinum: 80-135 HV)
Silver 70-90 HV
Bronze 60-150 HV (100-200 HV treated)
Aluminium 120-200 HV
Gold 120-200 HV (18k or 14k)
Palladium 150-200 HV
White gold 150-250 HV
Stainless steel 150-250 HV (special 1200 HV)
Titanium 150-200 HV (grade 2) / 300-400 HV (grade 5)
Ceramic 1200-1400 HV (1500-2000 for alumina)
Sapphire 2000-2300 HV
