Sterling silver, also called fine silver, is a beautifully lustrous cool-toned precious metal favored in fine jewelry among other products. The most reflective of all metals (excluding mercury), sterling silver looks stunning by itself and brings out the best hues in an array of colorful gemstones.
Sterling silver can be polished to a higher sheen than platinum. In fact, Ag, the chemical symbol for silver, comes from a word that means “white and shining.” The surface of silver can boast that shiny, polished appearance, or can be brushed, satin, matte, sandblasted, antiqued or oxidized (chemically blackened).
In order to be called sterling silver, a metal must be made up of a minimum of 92.5% pure silver and 7.5% alloy (meaning other metals), including but not limited to copper and nickel. The alloy is added to pure silver to make the metal more durable, tougher and harder. Sterling silver is designated a fineness of “925.” Pieces with sterling silver may be marked “sterling.”
Finishes on Sterling Silver
Finishing, or plating, is a common treatment with sterling silver. Popular types of plating are rhodium plating, gold plating and anti-tarnish plating. Plating is used to extend the life and sheen of the jewelry. After sizing or buffing a piece of jewelry with a machine, it must be re-plated to restore the finish.
Caring for Sterling Silver
Sterling silver becomes tarnished as the result of a natural chemical process that occurs when sterling silver is exposed to chemicals in the air, rubber, wool and latex. Humidity also plays a role in accelerating tarnishing. It's easy to keep your sterling silver sparkling, though, by taking a few steps to prevent tarnish and other wear and tear.
Known for its fiery combination of colors, opal is called the "Cupid stone" because it was said to reflect the complexion of the Greek god of love. The ancient Romans believed the gem was the symbol of hope, good luck and purity. Today, it remains a symbol of hope and inspiration. With a name stemming from the Latin word for "precious stone," opal is considered October's birthstone and is traditionally given as a 14th anniversary gift.
Opals are luminous and iridescent stones with inclusions of many colors called "fire." It is sometimes called the "queen of gems" because it can flash patterns of color representing every hue of the rainbow. In fact, most stones are usually cut into domed cabochons to enhance the color play. The brilliance and pattern of an opal's fire determines its value. Opals with strong flashes of red fire are generally the most prized, while stones with blue or green flashes are more common and subsequently less valuable. Stone size also helps determine price, since the gem is very rare in larger sizes.
In order to produce a stone that is less expensive than a solid opal, an opal doublet can be manufactured. It is composed of a thin layer of opal glued on top of another mineral (usually a black onyx or ironstone, which enhances the opal's color). An opal triplet can be made with a thin layer of opal sandwiched between a layer of clear quartz on top and a layer of obsidian or ironstone on the bottom. The clear quartz top layer makes the gem harder and less susceptible to scratches. Since top-quality natural opals are extremely rare and expensive, many are treated with colorless oil, wax or resin to enhance their appearance. Ranking a hardness of 5.5-6.5 on the Mohs Scale, these treatments also fill cracks in the stone to improve durability.
A species of quartz, opal is one of the few gemstones that are sedimentary in origin. Millions of years ago, after ancient seas receded, silica-laden sediment was deposited around shorelines. Erosion made much of this silica into a solution that filled cracks in rocks, clay and fossils. Layers upon layers of silica jell were added to each other over millions of years and became precious opals. The stones still contain 6 to 10 percent water, a remnant of ancient seas. Because they have high water content, opals should be protected from heat and strong light in order to prevent them from drying out and cracking.
Opal is found in a range of hues, including white opal (the most common), black opal (the most valuable), boulder opal (black opal with iron oxide), crystal or water opal (which is transparent), and fire opal (which features a bright solid color). The body color determines the variety of opal and has a large impact on the value.
White opals tend to have more diffused fire due to their light background color. Rare black opals have a black to dark gray body color that allows for the fire to be the most noticeable, making them the most valuable type of opal. Boulder opals are cut with the natural host rock left on the back. They are found with interesting hills and valleys on the surface and inclusions in the foreground, forming odd shapes that make them a designer's delight. Crystal opal is transparent with flashes of rainbow colors, while fire opal only occasionally has this play of color. Fire opal's backdrop color is the main attraction. With bold yellows, oranges or reds, it is usually faceted to add sparkle and enhance the fabulous color.
The vast majority of the world's opal supply comes from Australia, first discovered there by gold panners in 1863. In addition to a small quantity of opal produced in Kenya and Canada, white opal is mined in Brazil, black opal is found only at Lightning Ridge in Australia, crystal and fire opal can be found in the United States and Mexico, and a blue-green opal is found in the Andes Mountains of Peru.
Opals have been treasured for thousands of years throughout the world. The gem was loved and highly valued by the Romans, who called it "opalus." In fact, a beautiful opal called the "orphanus" was featured in the crown of the Holy Roman Emperor and was said to guard the regal honor. The Aztecs mined opal in South and Central America and archaeologist Louis Leakey found 6,000-year-old opal artifacts in a cave in Kenya. Napoleon gave Josephine a beautiful opal with brilliant red flashes called "The Burning of Troy," making her his Helen. To this day, opals are still set in the crown jewels of France. Queen Victoria loved opals and often gave them as wedding gifts. She was one of the first to appreciate opals from Australia and, along with her daughters, created a fashion for wearing the gemstone.
There are also several literary references to the fascinating stone throughout history. Shakespeare regarded opal as a symbol of shifting inconstancy, comparing its play of color to play of mind. In "Twelfth Night" he wrote, "Now the melancholy God protect thee, and the tailor make thy garments of changeable taffeta, for thy mind is opal." In the 19th century, Sir Walter Scott caused a reputation that opals were unlucky. The heroine of his popular novel had her life force caught in the opal she wore in her hair and died when its fire was extinguished.
For thousands of years, opals have been revered for their supposed mystical powers. Romans thought the stone kept the wearer safe from disease and wore it near the heart on necklaces to ward off evil and protect travelers. Ancient Arabs believed that opals fell from heaven in flashes of lightning, which explained their fiery colors. During the Middle Ages, opal was called "ophthalmios," meaning "eye stone," due to a widespread belief that it was beneficial to eyesight. Some thought its effect on sight could render the wearer invisible, and the stone was even recommended for thieves. In medieval Scandinavia, blonde women wore opals in their hair to prevent it from going grey.
Today, opals are still believed to hold magical powers. White opals, when used in rituals on a full moon night, are said to bring the moon goddess' powers into full effect within the practitioner. Specially shaped black opals are often worn on gold jewelry to further enhance their magical properties and powers. A fire opal surrounded with 10 or 12 diamonds and worn on a gold necklace is said to have excellent money-drawing power.
Opals have been said to bring good luck, grant vigor and ideally protect travelers. The stones have long been believed to develop and increase mental capacities and open the unused powers of the mind. The colorful fire in opals is said to develop a more creative imagination and help recall past lives. It is believed that the most magically powerful opals come from Lightning Ridge in Australia and that the gem loses its power once its owner dies.
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.
