Gold has an extraordinary heritage with unique qualities. As an enduring element found naturally in a distinct yellow color, gold 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.
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.
The color of gold is determined by two factors: the type of metal alloys used in making it and the percentage of these metal alloys used.
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. Replating is a simple process that Blue Nile offers to restore your jewelry\\\'s black finish.
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.
Gold jewelry prices are dependent upon the purity of the gold used or karat weight, the market value of gold, and the level of craftsmanship and design of each jewelry piece.
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.
