Turquoise Gemstone Information

About Turquoise - History and Introduction

Turquoise, one of the oldest known gemstones, has captivated cultures and civilizations for thousands of years with its striking blue and green hues. The name "turquoise" comes from the French "turqueise", meaning "Turkish stone", because it was first transported to Europe via a Turkish nation. The color that we recognize as turquoise was named after this gemstone. We have a diverse selection of turquoise for sale.

Turquoise stone was used by the ancient Egyptians and Aztecs as a jewelry gemstone and decorative stone. King Tutankhamun's burial mask and tomb was inlaid with turquoise. The ancient Egyptians believed that the color blue was a symbol of regeneration, so turquoise was treasured for both decorative and superstitious purposes. The Mesoamericans created turquoise mosaics and the Chinese carved turquoise into ornaments. Turquoise gemstone was also used by Native Americans in works of art and jewelry, some of whom believed that it possessed protective properties. The Tibetans believe in the healing properties of turquoise and have valued turquoise jewelry for centuries.

Turquoise occurs as botyroidal (grape-like) masses or nodules in fissures. The best quality turquoise stone is located in Northeast Iran. Turquoise deposits are also found in Afghanistan, Argentina, Australia, Brazil, China, Israel, Mexico, Tanzania and the USA.

Turquoise Color

Turquoise is the only gemstone that has a color named after it. Turquoise is sometimes mixed with malachite or chrysocolla, which causes a blue and green mottled appearance. The turquoise that is found in the USA contains iron rather than aluminum, so it is actually a mixture of turquoise and chalcosiderite. Since it contains iron, it is a green color. Pure blue turquoise is rare and turquoise is mostly interspersed by brown, dark-grey or black veins, which can be sparse or dense. These veins are either the host rock or other minerals and turquoise that contains veins is referred to as "turquoise matrix". The most popular color of turquoise is sky-blue (also called "robin's egg blue" or "Persian blue"), followed by blue-green or apple-green.

Turquoise Clarity and Luster

Turquoise gemstones are translucent to opaque, though translucent materials are rare. It exhibits a waxy to matt luster. Most turquoise has dark-grey, brown or black veiny inclusions of matrix or other minerals. These inclusions can be sparse or dense. The most desirable turquoise is translucent, pure and free from veins. However, sometimes veined turquoise has attractive patterns that make it desirable, such as "spider web turquoise" (also called "cobweb turquoise matrix") which has beautiful web-like patterns.

Turquoise Cut and Shape

Turquoise is mostly cut en cabochon for earrings, brooches, necklace pendants, bracelets, belts and rings. It may be cut into oval or fancy cabochons. Due to turquoise being one of the softer gemstones, it is also carved into ornamental objects and used for inlay. Spherical turquoise beads are also popular for bracelets, earrings and necklaces, as are tumbled pieces of turquoise and turquoise chips.

Turquoise Treatment

Turquoise is a porous material, so it is sometimes impregnated with polymers, wax or plastic to enhance the color and harden its surface. Turquoise color is also enhanced with the use of oil or paraffin, colors or copper salt. Imitation turquoise is made from dyeing chalcedony or howlite. Powdered turquoise is glued and glass, porcelain and plastic are used to make imitation turquoise gemstones. "Neolite" is a turquoise imitation with a dark matrix, also known as "Reese turquoise". "Neo turquoise" is another imitation turquoise with a dark matrix. "Viennese turquoise" is another imitation turquoise. All reputable gem traders declare any enhancement or treatment of turquoise gemstones, and should inform buyers of synthetic or imitation material.

Variscite

Turquoise is sometimes referred to as a cousin of lapis lazuli due to its similar appearance. It sometimes mixed with malachite or chrysocolla, which causes a blue and green mottled appearance. Turquoise found in the USA contains iron rather than aluminum, so it is actually a mixture of turquoise and chalcosiderite.

Turquoise is sometimes mistaken for variscite. However, variscite is typically greener. Chrysocolla can be confused for turquoise, but turquoise is harder and has a waxy or matt luster, whereas chrysocolla tends to exhibit a vitreous luster.

Turquoise has a long history of use as a talisman or amulet. The ancient Egyptians, Mesoamericans, Native Americans and Tibetans have believed in the special powers of turquoise for centuries. Some believed that turquoise can protect its wearer from harm, whilst others thought that it brought good luck or longevity. Moreover, some cultures accredited turquoise with the ability to reflect the health of the wearer; its color fading when worn by those in ill health and becoming deeper and more vivid when worn by a healthy person.

Today, turquoise is regarded as a protective stone, believed to enhance careers and support safe travels. It is thought to promote effective leadership and facilitate clear communication. On a physical level, turquoise is believed to help alleviate migraines and support the health of the brain, eyes, ears, neck, lungs, and throat. It is also associated with feelings of peace and balance, particularly the harmony between masculine and feminine energies. In traditional Hindu belief systems, turquoise is linked to the Ajna (third eye) and Vishuddha (throat) chakras. Ajna is associated with the pineal and pituitary glands, intuition, and intellect, while Vishuddha relates to purification, wisdom, and verbal expression. Turquoise serves as the traditional birthstone for December and is a zodiac stone for those born under Sagittarius. Additionally, in feng shui, turquoise embodies the energy of water.

Turquoise is popular in tribal and ethnic jewelry, especially in native American and Tibetan styles using silver. However, it looks equally stunning when set in yellow precious metal, such as in Egyptian inspired jewelry. Large turquoise gemstones make bold designs whilst turquoise chips and small beads lend themselves well to more delicate designs. The cool color of turquoise makes it a perfect summer gemstone and turquoise jewelry can be made to suit any preference, from simple wire-wrapping or beaded pieces to intricate antique designs. Cartier accent a turquoise cabochon cocktail ring with diamonds set in yellow gold. Bulgari use turquoise inlay with clashing colored gemstones and diamond accents, also in yellow gold. Turquoise can also be seen in men's jewelry such as rings and cufflinks, and as embellishments to men's accessories, such as leather belts.

Note: Buy colored gemstones by size and not by carat weight. colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamonds by weight in comparison.

Probably the most famous turquoise of all can be seen in the inlay of Egyptian King Tutankhamen's funeral mask.

Displayed in the British Museum are a number of ancient Mesoamerican works of art covered with turquoise mosaic work, including a wooden ceremonial shield, a rain god mask and a double-headed serpent.

The Smithsonian Institution also has a collection of interesting turquoise artefacts; a Chinese snuff bottle, a Navajo bracelet and Empress Marie-Louise's Diadem. The diadem was given to Empress Marie-Louise by Napoleon when they were married. It was originally set with emeralds, which were changed for turquoise gemstones in the 1950s by Van Cleef & Arpels, who acquired the diadem in 1953 and later sold the emeralds as individual pieces of jewelry.

Maria Magdalena Philomena Juliana Johanna de Tornos y Steinhart, Duchess of Vendome, wore a turquoise diadem for her wedding to Prince Jean of Orleans, Dauphin of France, Duke of Vendome, on 2nd May 2009 at Notre-Dame Cathedral in Senlis.

Turquoise jewelry has been seen adorning stars such as Salma Hayek, Heidi Klum, Scarlet Johansson, Megan Fox, Blake Lively, Sarah Jessica Parker and Eva Mendes.

At a gala dinner in Los Angeles celebrating the launch of Tiffany & Co.'s Blue Book 2024 Céleste collection, Emily Blunt adorned herself with a Jean Schlumberger by Tiffany Floret Necklace that showcased 105 carats of turquoise, complemented by diamonds.

Since it is a porous material, turquoise must be properly cared for in order to maintain its color and luster. Turquoise is sensitive to heat and if exposed to 250 degree Celsius heat, the color will turn a dull green. If exposed to prolonged direct sunlight, perspiration, oil, perfume, detergent or other chemicals, turquoise can suffer color deterioration. It would be prudent to remove turquoise rings before washing hands or engaging in household chores. Additionally, when dressing it is advisable to put on turquoise jewelry last and remove it first when undressing, to avoid exposure to hairspray, perfume or similar cosmetic products. Turquoise is considered to be fairy tough, but it is also fairly soft at 5-6 on the Mohs scale. It's softer than many gemstones, but with care, jewelry and ornaments can last for many generations. Turquoise gemstones should be stored separately to other gemstones to avoid scratches. Turquoise can be quite sensitive to strong pressure, high temperatures and harsh household chemicals and cleaners. Avoid exposing turquoise to bleach or sulphuric acid. Most turquoise can be cleaned using warm, soapy water, but some dyed materials may not be stable. For dyed or impregnated stones, it's best to test a small area first to ensure stability. Wipe down stones using only a soft cloth and be sure to rinse well to remove any soapy residue.
