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. 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. 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. 10 K White Gold Created Emerald 5 Stone Journey Pendant Singapore Chain 18 Inches Included Additional Details ------------------------------ Department: womens
