What is Turquoise?Turquoise is an opaque mineral that occurs in beautiful shades of blue, bluish green, green, and yellowish green. It has been treasured as a gemstone for thousands of years. Isolated from one another, the ancient people of Africa, Asia, South America and North America independently made turquoise one of their preferred materials for producing gemstones, inlay, and small sculptures. |
Turquoise ColorsAfter blue, bluish green stones are preferred, with green and yellowish green material being less desirable. Departure from a nice blue color is caused by small amounts of iron substituting for aluminum in the turquoise structure. The iron imparts a green tint to the turquoise in proportion to its abundance. The color of turquoise might also be altered by small amounts of iron or zinc substituting for copper in the turquoise structure |
Turquoise Jewelry CareSmart jewelry design will surround the gem with a durable bezel that protects the sides of the gem from abrasion and impact. The bezel should be high enough to also protect the face of the gem. Even if the gem is protected by a bezel, turquoise jewelry should be worn with care and respect. Avoid wearing it during activities that put the gem at risk, and store it where it will not be scratched by other items of jewelry. Turquoise is often porous, with the ability to absorb liquids. These liquids can include perspiration, body oil, cleaning products, or any liquid that accidentally comes in contact. Once absorbed, these liquids can damage the turquoise or alter its color. If contact with cosmetics or potentially damaging liquid occurs, the turquoise should be washed with a soft cloth that is dampened with a very mild soap solution, followed by cleaning with a soft cloth that has been dampened with plain water. Then, after the turquoise is dry, |
Turquoise OccurrenceTurquoise is rarely found in well-formed crystals. Instead it is usually an aggregate of microcrystals. When the microcrystals are packed closely together, the turquoise has a lower porosity, greater durability, and polishes to a higher luster. This luster falls short of being "vitreous" or "glassy." Instead many people describe it as "waxy" or "subvitreous." Turquoise forms best in an arid climate, and that determines the geography of turquoise sources. Most of the world's turquoise rough is currently produced in the southwestern United States, China, Chile, Egypt, Iran, and Mexico. In these areas, rainfall infiltrates downward through soil and rock, dissolving small amounts of copper. When this water is later evaporated, the copper combines with aluminum and phosphorus to deposit tiny amounts of turquoise on the walls of subsurface fractures. |
Natural Untreated Turquoise
Natural Untreated Turquoise is the name for turquoise that is fashioned into cabochons, beads or other items and used to manufacture jewelry without any type of treatment. It is the most highly desirable type of turquoise, especially when it has an attractive color. You are most likely to find it for sale in stores that specialize in fine turquoise jewelry, those that sell high-quality one-of-a-kind items, or those that specialize in natural, untreated gems. Sellers of natural untreated turquoise frequently use the fact that no treatment has been done as a selling point.
Stabilized Turquoise
Stabilized Turquoise is the name used for turquoise that has been impregnated with a polymer or other binding material to make it durable enough for cutting and use in jewelry. Straight from the mine this turquoise is too soft, too porous, too fractured or too fragile for manufacturing. Stabilized turquoise can be cut into beautiful beads and cabochons. It is the most common type of turquoise in today's gem and jewelry market. It is widely accepted because the supply of natural turquoise is much smaller than the demand from people who want it. The fact that an item is made from stabilized turquoise should always be disclosed to the buyer prior to sale, and the value should be lower than untreated turquoise of similar quality.
Composite or Reconstituted Turquoise
Composite or Reconstituted Turquoise is made from small pieces of turquoise that are mixed with a polymer and cast into block-shaped pieces. Finely crushed turquoise and some non-turquoise materials are sometimes included. The blocks are then sawn into small pieces that are used to cut cabochons, beads and other items. This material is often called “block turquoise” because of this manufacturing method. Sellers who pride themselves on selling only natural gems frequently decline to sell reconstituted turquoise. Some gem identification labs decline to call this material "turquoise" and instead label it as a "man-made product." At the same time, some vendors are glad to sell these materials and jewelry made from them because they often have an attractive appearance and a low value
Dyed Turquoise
Dyed Turquoise is exactly that. Turquoise is a porous material and easily accepts dye. The dye is used to modify the turquoise to a more marketable color. Dye can also be used to produce an outrageous color. Composite and reconstituted turquoise are the most commonly dyed materials. Dye can be used to color the turquoise or to color the polymer binding material. Sometimes black or brown dye is used to alter the color of matrix material to make it more obvious and uniform. Dyed turquoise is always worth less than untreated material of a similar color and quality.
