Known for its gleaming luster and durability, gold is a very timeless and desired metal used in jewelry. In its purest form, gold is extremely soft and malleable; however, it is mixed with other metals to form a durable alloy to use for jewelry. Not only do these alloys increase the strength of gold, it also produces different shades of gold including: yellow, white, and rose (pink) gold. Gold does not corrode, tarnish or rust, providing lasting beauty.  

24 Karat Gold
This is gold its purest form. The metal is comprised of 100% gold, containing no other metals. It is extremely soft and pliable, which is why it's often mixed with other metals, such as copper and silver for everyday wear and tear.

18 Karat Gold
18k gold means the metal is 18 out of 24 parts pure gold, or in other words, 75% gold and 25% alloy metals. 18 karat gold has been found to be the perfect balance between gold purity and strength.

14 Karat Gold
14k gold is the standard for American jewelry. It is 58.3% pure gold and the remainder is composed of alloy metals. Any gold purity less than 14 karat gold is not recommended for high quality jewelry.

10 Karat Gold
10k gold is the minimum level of purity for an item to be classified as real gold in the United States. It consists of 41.7% pure gold and the alloys consist of 58.3%.
Gold Purity Table

Authentic gold jewelry bears a “karat mark,” which is a "k" stamp. It typically appears as the karat weight (for example, 18 or 14) followed by ‘K,’ ‘KT,’ or ‘Karat’ somewhere on the jewelry. It is also common to encounter the numbers 750 and 585 stamped on your jewelry. These three digit numerals are referring to the approximate percentage of pure gold. For example, 750 equals 18k because 18k gold is 75% pure while 585 is the standard value for 14k because this karat mix is 58.5% pure gold.

Colors of Gold
Yellow gold is the most classic shade of all precious metals and is often used to create fine jewelry. It is alloyed with copper, zinc and silver. There can be a difference in shading depending on how pure the gold is. For instance, 18k gold will be richer and more brilliant in color than 10k gold.

White gold is another popular choice for engagement and wedding rings. It’s alloyed with palladium, zinc, copper, tin, and manganese. The highest quality of white gold jewelry is generally 18 karats, consisting of a mixture of pure yellow gold and palladium. White gold is highly reflective and not subject to tarnish.

Rose gold, also known as pink gold receives its romantic hue from the addition of copper and in some cases, silver. The more copper added into the compound, the darker the rose coloration will be. The most precious rose gold has a 22 karat weight. The more common 18 karat rose gold is comprised of 25% copper and 75% gold.

Known as one of the most pure and precious metals, platinum is a very popular metal used for engagement rings and wedding bands, as well as in fine jewelry. Platinum jewelry is at least 90-95% pure. By comparison, 18k gold is 75% pure, and 14k is 58% pure gold. It is 35 times more rare than gold and has a brilliant white luster that enhances the diamond’s sparkle and appearance. It is also the strongest precious metal used in jewelry. Its density and weight makes it more durable than other metals and for that reason it is highly sought after. Platinum jewelry is a perfect choice for everyday wear. Platinum does not wear down unlike other metals, so even when it is scratched, it will remain virtually the same weight and size. Platinum will last forever, making it the ultimate pick for your jewelry.
