Purple gold (also called amethyst gold and violet gold) is an alloy of gold and aluminium rich in gold-aluminium intermetallic (AuAl2). Gold content in AuAl2 is around 79% and can therefore be referred to as 18 karat gold. Purple gold is more brittle than other gold alloys, (a serious fault when it forms in electronics), as it is an intermetallic compound instead of a malleable alloy, and a sharp blow may cause it to shatter. It is therefore usually machined and faceted to be used as a “gem” in conventional jewelry rather than by itself. At a lower content of gold, the material is composed of the intermetallic and an aluminium-rich solid solution phase. At a higher content of gold, the gold-richer intermetallic AuAl forms; the purple color is preserved to about 15% of aluminium. At 88% of gold the material is composed of AuAl and changes color. The actual composition of AuAl2 is closer to Al11Au6 as the sublattice is incompletely occupied.

Purity 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. We craft our jewelry using both 18k and 14k gold. 18k gold is composed of 75% gold, which is alloyed with other metals to make it strong enough for everyday wear. 14k gold is composed of 58.3% gold and 41.7% of other metals.

White gold’s properties vary depending on the metals and proportions used. As a result, white gold alloys can be used for many different purposes; while a nickel alloy is hard and strong and therefore good for rings and pins, gold-palladium alloys are soft, pliable and good for white gold gemstone settings, sometimes with other metals like copper, silver, and platinum for weight and durability, although this often requires specialized goldsmiths. The term white gold is used very loosely in the industry to describe karat gold alloys with a whitish hue. It is a common misconception that the color of the rhodium plating, which is seen on many commercial pieces, is actually the color of white gold. The term “white” covers a large spectrum of colors that borders or overlaps pale yellow, tinted brown, and even very pale rose. The jewelry industry often conceals these off-white colors by rhodium plating.

Care Since gold is a natural element, it is affected by harsh chemicals such as chlorine or other cleaning products. We recommend that you remove your jewelry when using chemicals to reduce daily abrasions and prolong the luster. To clean gold jewelry, use a solution of warm water and detergent-free soap with a soft-bristled brush. When not worn, store your gold pieces in soft cloth bags or the original box to protect them from the elements of daily exposure. Shop our yellow, white, and rose gold jewelry collections.

Cobalt-containing alloys, e.g. 75% gold with 25% cobalt, form a black oxide layer with heat treatment at 700–950 °C. Copper, iron and titanium can be also used for such effect. Gold-cobalt-chromium alloy (75% gold, 15% cobalt, 10% chromium) yields a surface oxide that’s olive-tinted because of the chromium(III) oxide content, is about five times thinner than Au-Co and has significantly better wear resistance. The gold-cobalt alloy consists of gold-rich (about 94% Au) and cobalt-rich (about 90% Co) phases; the cobalt-rich phase grains are capable of oxide-layer formation on their surface.

White Gold 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.
