Turquoise History The word “turquoise” was derived from the French term “pierre turquoise,” meaning “stone of Turkey.” This was after a 16th century European misconception that the stones originated in Turkey, when in fact they were first discovered in Persia. Turquoise is formed over millions of years with a chemical reaction when water leaks into rocks containing copper and aluminum minerals. Experts believe turquoise was first mined in 6000 B.C., by ancient Egyptians. Today, it is mined in countries all around the world, including, China, Iran, the United States, and Tibet. Turquoise jewelry was first discovered within Egyptian tombs that date back to 3500 B.C. Cultures around the world have embraced the tradition of turquoise jewelry in the belief that it possesses healing and protective powers. While turquoise jewelry continues to be worn by many who believe it will attract money, luck, and love, today, it is also a prevalent fashion accessory and serves as a December birthstone, as well as the stone for the fifth and eleventh wedding anniversaries. Types of Turquoise Turquoise may range in color from light blue to green. It may contain a variety of natural definitions, from white to black, which adds a one-of-a-kind look to each stone. While the variances in color and matrix do not affect the value of the stone, there are properties that make some turquoise more expensive than others, most likely color uniformity and vividness. Turquoise jewelry is often treated in order to bring out the vibrant color and radiance of each stone. Caring for Your Turquoise Jewelry Like all natural gemstones, turquoise can be damaged if not cared for properly. Clean with warm, soapy water and a soft cloth, drying after washing. Avoid scratches by storing separately from other jewelry. Avoid exposure to oils, perfumes, and chemicals that may affect the stone’s vivid color.

Contemporary designs have a strong Balinese artisan influence, and are characterized by ornate flourishes and the innovative use of semi-precious stones. Gemstones Color Jewelers describe the color of a gemstone in terms of three characteristics: hue, saturation, and tone. A gemstone's basic color is its hue, and those with purer hues (for emeralds, green; for sapphires, blue; and for rubies, red) are generally considered more valuable. Often, however, a hint of another color can be detected. Saturation is a measure of the intensity or purity of a gem's hue and is determined by the degree to which gray or brown hues mute its defining color. Value tends to increase with saturation, so a fully saturated purplish blue sapphire may well be more expensive than a muted pure blue one. The tone of a gemstone, a measurement of its lightness or darkness, is usually given as light, medium-light, medium, medium-dark, or dark. Clarity A flawless gemstone is rare and expensive. As with diamonds, most gemstones have inclusions, or tiny mineral flaws, that can be seen under magnification or by the careful eye. Make sure that any inclusions in the stone do not penetrate deeply into the gem, as this may cause it to break or crack. Clarity grades range from VVS (very, very slightly included) to I3, in which inclusions are prominent and severely affect the gemstone's beauty. Cut A gemstone's cut refers to its proportions and symmetry. In making a gemstone look appealing--the stone should be symmetrical in all dimensions so that it will appear balanced, and that its facets will reflect light evenly. Color should also be taken into account when cutting for optical efficiency. If a stone's color is highly saturated, a shallow cut will allow it to pass more light, while a deeper cut may increase the vividness of a less saturated gem. There is no generally accepted grading system for gemstone cut. Size Though a gemstone's weight is usually given in carats, this may not give an accurate idea of its size, because different types of stone have different densities. Therefore, a one-carat sapphire or ruby will be smaller than a one-carat emerald, though they have the same weight, because sapphires and rubies (both a form of the mineral corundum) are more dense than emeralds. Gemstones can also be measured in dimensions (diameter, length, and width). It is important to know the dimensions to ensure that the gemstone weight will be visible and well-proportioned in the setting. Gemstone Treatment Gemstones are often treated to enhance color and fill cracks. Please note: if a gemstone has been treated, this information will be provided in the specifications on the stone's product detail page. There are various accepted techniques, depending on the type of stone: Oils and resins are frequently used to fill surface-reaching fissures in emeralds and rubies. This process is not permanent; however, if a treated ruby or emerald is subjected to high heat, the filler may leak out of the stone. Sapphires and rubies are often heated in a kiln or furnace to enhance their color. Such heat treatment, which is considered permanent, has been used for centuries. Lightly colored sapphires may also undergo diffusion treatment. This is done by heating a stone in the presence of coloring elements such as titanium or iron, which causes a thin layer of color to be diffused into the stone's surface. Because this color layer is so thin, a diffusion-treated sapphire should not be re-polished. Gemstone Care To clean gemstone jewelry, first wipe it with a soft cloth to remove any dirt. Emeralds require only the use of a soft cloth, as cleaners may damage these soft gems. Sapphires and rubies can be cleaned with either an ultrasonic cleaner or a solution of one part ammonia to six parts water, with a soft brush. Store your gemstone jewelry in a soft cloth pouch or jewelry case so it does not touch other pieces in your collection. As with all jewelry, normal wear and tear can loosen prongs and settings, so it is a good idea to have it checked by a professional jeweler who can make repairs as needed.
