Reconstituted turquoise is enhanced through a process in which genuine gemstone fragments are powdered and bonded with resin to reinforce the stone.
All weights pertaining to gemstones, including diamonds, are minimum weights. Additionally, please note that many gemstones are treated to enhance their beauty. View Gemstone Enhancements and Special Care Requirements for important information.
By far the most common color of gold used in jewelry, yellow gold is gold in its natural shade. Yellow gold is usually alloyed with copper and silver to increase the strength of the metal. How yellow the metal is depends upon the content of gold. A 14-karat piece of jewelry will have a brighter yellow hue than a 10-karat piece. Likewise, an 18-karat piece of jewelry will have a deeper yellow than 14-karat gold, and so on.
Gold's softness and malleability make it a wonderful metal to work with when creating virtually any design in jewelry. But this softness can be a drawback as well. To make it stronger and more durable, gold is usually alloyed, or mixed, with other metals such as copper or silver. The higher a metal's percentage of gold content, the softer and more yellow the jewelry piece. The karat weight system used to measure gold in a piece is the same for all hues, including white and yellow gold.
The word “carat” is Arabic, meaning “bean seed.” This is because historically seeds were used to measure weights of gold and precious stones. In the United States, “karat” with a “k” is used to measure gold's purity, while “carat” with a “c” is used in measuring a gemstone's size. The karat mark of gold represents the percentage of pure gold to alloy.
In order to determine the karat weight of a specific item, simply look for the quality mark. Jewelry items will bear the stamp of their karatage based upon the United States or European system of marking. The United States system designates pieces by their karats—24K, 18K, 14K, 10K, etc. The European system designates pieces by their percentage of gold content. For instance, 10K gold is marked “417,” denoting 41.7% gold; 14K is marked “585,” denoting 58.5% gold; and 18K is marked “750,” denoting 75% gold; etc.Necklace Clasp Types
Barrel Clasp: Used on most rope chains to make the chain more secure. The barrel clasp looks like part of the chain and twists to get a pendant on and off.
Lobster Claw Clasp: As a traditional clasp style found in bracelets and necklaces, the lobster claw is generally reserved for heavier styles that may need added strength. The closure's shape is more oblong, similar to a teardrop shape, and is controlled by a tip that opens and closes the spring in the clasp. This type is also considered a more expensive finding that can add to the overall value of the jewelry piece.
Magnetic Clasp: The popularity of the magnetic clasp has greatly increased in recent years. It is a quick and easy way to secure jewelry while not having to fuss with a tiny clasp, which can be difficult if you have long fingernails, arthritic hands or other mobility challenges. A magnetic clasp relies on a strong internal magnet that works to pull both ends of the clasp together. In most cases, a magnetic clasp is used for light to medium weight jewelry pieces that do not put excessive stress on the magnet.
S-Clasp: An S-shaped piece of metal that connects a chain by hooking metal rings on each end of the S-shape.
Slide Insert Clasp: This type of clasp is exactly as it sounds. With a box-like shape that is hollow on the inside, the wearer will slide the nearly-flat tab into the box until it clicks, indicating a secure closure. On some jewelry, a slide insert clasp will be accompanied by a side safety catch, which adds strength and security to the clasp. Although this type of clasp is found on both bracelets and necklaces, it is particularly popular on bracelet styles. These types of clasps are often reserved for more expensive jewelry.
Spring Ring Clasp: One of the most common closure types, the spring ring clasp is typically used for light to medium weight bracelets or necklaces. It is round in its design and features a small tip which controls the opening and closing of the spring. The circle then closes around another smaller loop or link at the other end of the strand.
Toggle Clasp: A toggle clasp is a narrow piece of metal, usually designed in the shape of a bar, which is then pushed through a circular ring to act as a fastener. Unlike the lobster claw or spring ring clasps, a toggle clasp is not controlled by a spring. The pretty design is less secure than other closure types, but is usually meant to be a big part of the design and is meant to "show". The clasp is an attractive way to secure a chunkier link bracelet or necklace.
The length of a necklace or chain you buy depends upon a number of factors, including what you will be wearing with it and your neck size.
To measure your neck, wrap a soft, flexible tape measure around the base of your neck. This is the same measurement used for collar sizes in men's shirts. A good rule of thumb is to buy a necklace or chain a minimum of two sizes up from your neck measurement. Thus, a man with a 17" neck would want to skip the 18" size and get a 20" size to ensure a comfortable fit.
Appropriate women's necklace lengths are more dependent upon the style than neck measurement. Knowing your basic neck measurement, though, will help you decide what length will work best with your outfit and create the look you are after.
With its uniquely mystical appearance, quartz was the “rock crystal” used in ancient times to make crystal balls. It was believed to attract energy and is still considered to be spiritual today. The gemstone was once believed to be a compact form of ice. In fact, the Greeks originally named quartz “krystallos,” meaning ice, but this terminology soon applied to any type of crystal.
Often identified by its six-sided prism shape, quartz is the most common mineral on Earth, found in nearly every environment throughout the globe. With a ranking of 7.0 on the Mohs Scale, it is a component of almost every rock type and occurs in virtually every color imaginable. Quartz has a great amount varieties that are well-known by other names, including amethyst, citrine, ametrine, rock crystal, agate, druzy, chalcedony, tigers eye and many more. There are also several varieties that hold the name “quartz,” including rose quartz, smokey quartz and rutilated quartz.
The pale pink color of quartz is known as rose quartz, the traditional gift for couples celebrating their 2 nd anniversary. It is a delicate powder pink color that ranges from transparent to translucent. Transparent rose quartz is quite rare and is usually so pale that it does not show much color, except in large sizes. The translucent quality of rose quartz is much more common and is used for jewelry and carvings.
Rose quartz is probably one of the most prized stones for its mystical properties. Known as the “Heart Stone,” it is believed to have incredible powers to balance emotions and open the heart. Folklore says rose quartz can comfort brokenhearted people, bringing healing and clarity to the heart and allowing the wearer to learn to trust again. The stone is also said to foster happiness and the joy of life by bringing about contentment in love and filling one with optimism, tenderness and gentleness.
In addition to helping with romantic love, rose quartz is believed to enhance all other forms of love as well, including self-love, platonic and maternal. Its loving, nurturing energy is said to take away fears, resentment and anger and replace them with feelings of higher self-esteem and confidence. This soothing stone is also thought to balance emotions and heal emotional wounds. It is said to be especially powerful in times of stress or loss, bringing peace and calm to the wearer.
Ranging in color from nearly black to smoky brown, smoky quartz is transparent and owes its warm earthen hue to exposure to natural radioactivity. Care must be taken since its rich color will fade in the sun. Spelled either “smoky” or “smokey,” this variety of quartz is often incorrectly called “smoky topaz.”
Smoky quartz is believed to help dissolve negative energy and release stress. It is said to be a mild sedative with a relaxing effect that calms, soothes and restores balance and harmony. Folklore says the gem can embrace dark areas with light and love and therefore clear and cleanse the body both physically and emotionally. Smoky quartz is thought to be a warm, friendly and down-to-earth gem.
Rutilated quartz is a type of transparent rock crystal that contains long, fine needles of rutile crystals (titanium dioxide). These highly valued inclusions form a landscape of shining gold needles in an array of patterns that is breathtakingly beautiful. These golden inclusions are also known as Venus hair, Cupid’s darts and fleches d’amour (“arrows of love”). There is a less well-known variety called tourmalinated quartz that, instead of golden rutile, forms black or dark green tourmaline crystals.
Although rutilated quartz is usually cut as a cabochon, it can be a difficult stone to attain a smooth surface without pits. This is because rutile ranks a 6.0 on the Mohs Scale , while quartz ranks 7.0. The difference in hardness between the two materials, and because of the way rutile forms inside, causes problems when cutting. Each final cut piece is unique, with no two being exactly alike. Modern folklore says rutilated quartz brings forth each person's strengths, originality and ability to relate to others.
Tourmalinated quartz is a clear form of quartz with silver-tone filaments and threads of black tourmaline running through it. Because tourmalinated quartz is a combination of quartz and tourmaline, it has influences and characteristics of both these gems.
All quartz rock that is absent of color is deemed rock crystal. This category of quartz has the clarity of pure water, without as much as a hint of pigment. While this colorless quartz is too common to be considered a precious gemstone, it is still beautiful, as well as affordable. Rock crystal is commonly used in decorative carvings, figurines and chandeliers. It is also easy to cut, making it well suited in the creation of eye-catching jewelry.
Phantom quartz is a variety of quartz which, over the course of millions of years, forms over existing rock crystals. It takes its name from the particular structure of the trigonal crystals that form within its shape, known as the phantom. Found mostly in Austria, Brazil, Madagascar, Switzerland and the United States, phantom quartz can also be found in smoky quartz, citrines and amethysts. These phantoms, or the inner crystals, are usually composed of other minerals such as chlorite, goethite, hematite or even other kinds of quartz like the smoky and milky quartz.
Mention of phantom quartz is found in 2000-year-old texts where it was believed to have formed on ice hidden in dark caverns for millions of years. This ice, when exposed to extreme cold, got encased with the quartz, thus trapping the phantom within. Perhaps because of their elusive beginnings, phantom quartz are sometimes referred to as ghost crystals, specter crystals or even shadow crystals.
One of the oldest known gems, turquoise has been prized for thousands of years. The Egyptians believed it had powerful mystical properties, and turquoise jewelry has been found interred with 7,500-year-old mummies. Ancient manuscripts from Persia, India, Afghanistan and Arabia say that the health of a person wearing turquoise could be assessed by variations in the color of the stone. Montezuma's treasure, now displayed in the British Museum, includes a carved serpent covered by a mosaic of turquoise.
Turquoise was especially revered by the Native American culture, an association that dates back to the Aztec empire more than 700 years ago. For the Aztecs, turquoise was reserved for the gods and mere mortals were forbidden to wear it. They believed it to be a gem of good fortune and a commodity more valuable than gold. Native Americans believed turquoise protected people from demons and they even placed turquoise in tombs to guard the dead. The stone's colors were thought to be symbolically blue for the heavens and green for the earth. Often warriors tied turquoise to their bows to ensure accurate shots.
Today, turquoise is still believed to provide protection and bring luck. It is said to also promote prosperity, love, healing, courage and friendship. The stone is thought to relax the mind and ease mental tension.
The gem's opaque turquoise color varies from shades of greenish blue to deep cobalt to sky blue. Some varieties display white or brown matrixes, which are streaks of the mother stone from which they came, while others have veins of black matrix running through them. Generally, the bluer the blue, the more highly valued the stone. A clear, even texture without mottling or veins is also preferred. The most rare and valuable color is an intense azure, but the most common is the mild to medium sky blue. Sometimes imitated by minerals such as chrysocolla, turquoise stones are often dyed or colored with coatings of various resins.
In the 13th century, turquoise was mistakenly believed to have come from the country of Turkey. Hence, its name came from the French word for Turkey, "Turquie". The stone was actually brought to Europe from Persia (now Iran), via Turkey. It is a mineral usually found in association with copper deposits and is sometimes mined as a by-product of copper mining.
Although turquoise is found in desert regions worldwide, especially in the southwestern United States, perhaps the finest and most valuable comes from the Sleeping Beauty mine in Globe, Arizona. It is named after the Sleeping Beauty Mountain which resembles a reclined woman in a slumbering state. Its turquoise is world renowned for its beauty that ranges from pure robin's egg blue to a darker royal blue.
While only ranking between 5.0 and 6.0 on the Mohs Scale of hardness, turquoise remains quite popular for jewelry. In Europe, turquoise rings are given as forget-me-not gifts, while in the United States, the stone is given as traditional 5th and 11th wedding anniversary gifts. It has even become a modern consideration for the December birthstone. When wearing turquoise over the years, the stone will absorb oil from a person's skin, causing a slight change to the color of turquoise.
Turquoise is commonly treated in various fashions to ensure its durability and visual appeal, especially when set in jewelry. If a stone has been treated, the type of process will be noted.
Turquoise is one of the oldest gemstones known in history going back 6,000 years BC and has been revered by almost every ancient culture. It is the alternate birthstone for December and has a Mohs rating of 5.0-6.0. Turquoise is a Hydrous Phosphate of Aluminum and Copper and may form as a chalky coating on rocks or finely disseminated crystals formed within small rock cavities. Rough such as this is not commercially viable, which has led to the development of reconstituted turquoise. Turquoise-bearing rock is pulverized and the turquoise is separated from the rock using a float process. The pulverized turquoise is then mixed with a colored resin, which is then injected into a mold to form a solid block. This is then cubed, preformed and fashioned into various shapes and sizes. It is an excellent method of using rough that would otherwise not be usable.
