| Quartz refers to a family of crystalline gemstones of various colors and sizes. Among the well-known types of quartz are rose quartz, and smoky quartz. A number of other gemstones, such as Amethyst and Citrine, are also part of the quartz family. Rusticated quartz is a popular type of quartz containing jewelry cards. Turquoise is found in only a few places on earth, and the world’s largest turquoise producing region is the southwest United States. Turquoise is prized for its attractive color, most often an intense medium blue or a greenish blue, and its ancient heritage. Turquoise is used in a great variety of jeweler styles. It is perhaps most closely associated with southwest and Native American jeweler, but it is also used in many sleek, modern styles. Some turquoise contains a matrix of dark brown markings, which provides an interesting contrast to the gemstone’s jewelry cards. Some gemstones are classified as organic, meaning that they are produced by living organisms. Others are inorganic, meaning that they are generally composed of and arise from minerals. Some gems, for example, amethyst, have become less valued as methods of extracting and importing them have progressed. Some man-made gems can serve in place of natural gems, such as cubic zircon, which can be used in place of diamond. For platinum, gold, and silver jeweler, there are many techniques to create finishes. The most common are high-polish, satin/matte, brushed, and hammered. High-polished jeweler is by far the most common and gives the metal a highly reflective, shiny look. Satin or matte finish reduces the shine and reflection of jewelry cards and is commonly used to accentuate gemstones such as diamonds. Hammered finishes are typically created by using a rounded steel hammer and hammering the jeweler to give it a wavy texture. Some jeweler is plated to give it a shiny, reflective look or to achieve a desired color. |
