By far the most common color of gold used in jewelry, yellow gold is gold in its natural shade. Yellow gold is usually alloyed with copper and silver to increase the strength of the metal. How yellow the metal is depends upon the content of gold. A 14-karat piece of jewelry will have a brighter yellow hue than a 10-karat piece. Likewise, an 18-karat piece of jewelry will have a deeper yellow than 14-karat gold, and so on.
Gold's softness and malleability make it a wonderful metal to work with when creating virtually any design in jewelry. But this softness can be a drawback as well. To make it stronger and more durable, gold is usually alloyed, or mixed, with other metals such as copper or silver. The higher a metal's percentage of gold content, the softer and more yellow the jewelry piece. The karat weight system used to measure gold in a piece is the same for all hues, including white and yellow gold.
The word “carat” is Arabic, meaning “bean seed.” This is because historically seeds were used to measure weights of gold and precious stones. In the United States, “karat” with a “k” is used to measure gold's purity, while “carat” with a “c” is used in measuring a gemstone's size. The karat mark of gold represents the percentage of pure gold to alloy.
In order to determine the karat weight of a specific item, simply look for the quality mark. Jewelry items will bear the stamp of their karatage based upon the United States or European system of marking. The United States system designates pieces by their karats—24K, 18K, 14K, 10K, etc. The European system designates pieces by their percentage of gold content. For instance, 10K gold is marked “417,” denoting 41.7% gold; 14K is marked “585,” denoting 58.5% gold; and 18K is marked “750,” denoting 75% gold; etc.
Because tourmaline is found in a wide range of colors, the gemstone trade generally does not use separate names for the gem’s individual varieties. Rather, the color is added to the beginning of the name, such as green tourmaline or pink tourmaline. However, there is a very special exception to this rule when it comes to the select tourmaline called rubellite.
Famous for its exquisite reddish-pinkish-purple color, rubellite is a tourmaline that is well-known for representing the joy of life and the passion of seduction. With a name derived from the Latin term “rubellus,” which means “reddish,” this exceptionally beautiful gemstone features a unique characteristic. Its color remains consistent in daylight and artificial light. While many gemstones change their color depending on the source of light, rubellite never changes. In contrast, the color of most other pink and red tourmalines shows a noticeable brownish hue in artificial light. But rubellite’s perfect reddish-pink color stays brilliant, making it a gorgeous anomaly in the gemstone world.
The majority of the stones are found in Brazil, Madagascar, Mozambique, Nigeria and Pakistan, but some beautiful pink rubellites have recently been discovered in the United States.
