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.”
Minimize scratches on sterling silver by storing it in its own compartment in your jewelry box or in a cloth pouch. Sterling silver may also be stored in sealed polyethylene bags.
Peridot features a lively yellow-green color that is transparent with an oily luster. The iron that creates peridot’s color is an integral part of its structure, so the gem is only found in various shades of green. It is most prized in lime hues, but Italian peridot is a rich olive color and popular American peridot is a beautiful light yellow-green. The Romans called peridot “evening emerald” because its exquisite green color was said to glow at night. This is perhaps because the stone exhibits double refraction, meaning that when looking through the stone, objects appear double. So when looking into a faceted peridot, the number of bottom facets appears to be double the actual number, creating a glittering sensation.
Pronounced PEAR-A-DOE, the word “peridot” comes from the French word meaning “gem.” It is the gem variety of the mineral olivine and ranks a 6.5-7.0 on the Mohs Scale.
Born in cauldrons of fire, peridot is considered the “volcanic gem,” since small crystals of it are often found in the rocks created by volcanoes. In fact, Hawaiian legend called peridot the divine tears wept by Pele, goddess of the volcano. The island of Oahu even has beaches made out of olivine grains, but they are much too small to cut into peridot. Samples of the gem also have been discovered in meteorites that have fallen to Earth, many of which are more than a billion years old.
Peridot traces its jewelry roots to 3,500 years ago. The stone was first mined by the ancient Egyptians on the volcanic island of Zebargad in the Red Sea. Known as the “serpent isle,” it was infested with poisonous snakes that interfered with mining activity until one Pharaoh had them all driven into the sea. Today, Native Americans mine most peridot on the San Carlos Reservation in Arizona. Interestingly, almost all peridot sold in Hawaii is from Arizona, despite the fact that peridot is produced by Hawaii's volcanoes. The gemstone is also found in Norway, Brazil, China, Egypt, Italy, Myanmar and Sri Lanka. An exciting new deposit was discovered in Pakistan in 1994, yielding some of the finest peridot ever seen, including one stone that weighed more than 300.00ct.
Peridot is among the oldest known stones and has been mined as a gem for thousands of years. As early as 1575 to 1350 B.C., the ancient Egyptians used peridot beads in their ceremonial jewelry. In fact, it is believed the stone was one of the favorite gems of Cleopatra and that some of the “emeralds” she wore were actually peridot.
Ancient Egyptians also carved small drinking vessels out of large chunks of peridot. Priests would drink soma from them in rituals, believing the soma would put them in touch with the nature goddess, Isis. Legend has it that King Soloman traded cedar trees from Lebanon for 12 soma drinking cups and 144 liters of soma. The Egyptians made this trade for ramp logs to build their pyramids at Gisa, while King Soloman was said to have been enlightened by drinking soma from the peridot cups. Today, Mexican hill tribes still drink soma from green glazed cups to put them in touch with nature and their ancestors’ spirits. Additionally, some Native American Indians in Arizona use tea made from peyote ground with peridot crystals in their rituals.
Peridot has also been important to other cultures throughout history. Late in the Ottoman Empire (1300 to 1900), peridot was a highly prized gem and Turkish Sultans amassed some of the world’s largest collections of the gemstone. It is mentioned in the Bible under the name of “chrysolite,” and was used to decorate medieval churches with samples that were most likely carried back to Europe by the Crusaders. Large stones weighing more than 200.00ct adorn the Shrine of the Three Magi at the Cologne Cathedral in Germany.
Throughout the ages, peridot has been believed to hold mystical powers of protection and healing. The ancients regarded the stone as a symbol of the sun and wore it in amulets to prevent nightmares and drive away evil spirits. It was even favored by pirates to protect them against evil. Peridot was said to be useful for calming raging angers, curing nervous afflictions and promoting quiet sleep. It was also used as a medical remedy to treat asthma and ward off fevers. Peridot was also believed to strengthen any medicine drunk from goblets carved from the stone. South American Shamans use peridot to ward off snakebites and the evil spirits who have taken the form of mosquitoes who bring the sleeping sickness. They also say the heating of magic mushroom tea by peridot takes them on trips to the ancestor heavens.
Today, peridot is believed to bring the wearer success, peace and good luck. To be most powerful, it is said that the stone should be mounted in gold and surrounded with small diamonds. With powers that are thought to bring protection and health, modern folklore also says it can be used to attract love and calm anger while soothing nerves and dispelling negative emotions. The gem is believed to protect the wearer from bad dreams when set in gold.
Peridot is considered the birthstone of August. Given as a symbol of fame, dignity and protection, this gem is also traditionally given to couples celebrating their 16th wedding anniversaries.
An ancient Persian legend states the Earth rests on a gigantic sapphire that gives its blue reflection to the sky. The most popular colors for sapphires range from light blue to a blue that appears black. Hence, the name was derived from the Latin form of the Greek word for blue, “sapphirus.” Bright daylight makes most sapphires shine more vividly than the somewhat muted artificial light. So the most highly cherished color for blue sapphires is not the darkest blue, but a deep and satiated blue, which even in dim, artificial light remains to appear blue.
While sapphires are best known for being velvety blue, it was decided long ago to consider all gemstones of the mineral family corundum to be sapphires. Non-blue sapphires are termed “fancy” and can be nearly any color, including yellow, green, white/colorless, pink, orange, brown, purple, golden and even black. Red corundum is the exception, however, and was given the special name of “ruby.” Since pink is really just a light red, the International Colored Gemstone Association has resolved to consider light shades of the red hue to be included in the category ruby, as it is too difficult to legislate where red ends and pink begins. In practice, however, pink shades of corundum are known as either pink ruby or pink sapphire. All sapphires rank a 9.0 on the Mohs Scale, second only to diamonds in hardness.
There are a great number of varieties of sapphire, many of which are quite rare and highly sought-after in the gemstone market. A rare orange-pink variety, known as padparadscha, can be even more valuable than blue sapphire. Pronounced PAD-PA-RAD-SHAH, the name comes from the Sinhalese word for lotus blossom. Endowed with both pink and orange color components, its hues range from pastels to fiery shades. Padparadscha sapphires are usually heat treated to improve and intensify their color, while the color of untreated stones will fade over time. An untreated padparadscha sapphire that has faded will return to its original pinkish-orange color, however, if exposed to sunlight for about an hour.
Another rare variety of sapphire is known as the color-changing sapphire. This stone exhibits different colors in different light. In natural light, color-changing sapphire is blue, but in artificial light, it is violet.
For experts and connoisseurs, the Kashmir-color is considered the most beautiful and valuable shade. It features a pure and intensive blue, which is enhanced by a fine, silky gloss. Its color does not change in artificial light, but remains intense with a deep, velvety sheen. Setting the standard for the color of top-quality sapphires, Kashmir sapphires were found in 1880 after an avalanche. They were intensely mined for only eight years until the source was depleted. The Burma-color is also considered especially valuable, ranging from rich royal blue to deep cornflower blue. Ceylon sapphires are prized as well for the luminosity and brilliance of their light to medium blue color.
There is a translucent variety of sapphire, called star sapphire, which displays a six-point star when cut into a smooth domed cabochon. The mineral rutile is embedded in an asterisk-shape within the stone, causing light to reflect in a phenomenon called “asterism.” Six- or twelve-ray stars appear to magically glide across the surface of the stones as they are moved. Star sapphires and rubies are expensive rarities and should always display the stars exactly in the center of the gem. Value is influenced by the intensity of the body color and the strength and sharpness of the star. The star stone is said to be the home of each person’s angel, who lives there in contentment with the sapphire’s spirit.
The stone is mined in many parts of the world. The oldest sapphire mines are situated in Ceylon, today called Sri Lanka, where gemstones were mined in ancient times. Most blue sapphires today come from Thailand or Australia, but sapphires from Kashmir and Myanmar (formerly Burma) are considered the most rare and highly prized. Sapphires are readily available in sizes of up to 2.00ct, but gems weighing 5.00-10.00ct are not unusual. The cushion-cut Logan Sapphire from Sri Lanka weighs an astounding 423.00ct and can be seen at the Smithsonian Institution in Washington, D.C. There is also a 258.00ct stone set in the Russian crown, which is kept in the Diamond Fund in Moscow.
Because the gem has long symbolized sincere love and enduring faithfulness, blue sapphires are often given in engagement rings to express commitment and loyalty. Many women throughout the world decide on the blue stone for their engagement rings, as the gem also represents truth, friendship, harmony and consistency. Sapphire blue has become a color related to anything permanent and reliable, making it an ideal stone to symbolize the promise of marriage.
Often referred to as “Gem of the Heavens,” sapphire also symbolizes a noble soul. It is September’s birthstone and is traditionally given as 5th and 45th wedding anniversary gifts. Star sapphires are given for the 65th anniversary. The color sapphire-blue is known for representing clarity and competence. In fact, the first computer to ever declare victory over a chess grandmaster and world champion was named “Deep Blue.”
Sapphires have been associated with magical powers throughout the ages. The Greeks identified white sapphires with Apollo and the oracles at Delphi used them to tap into the subconscious and super conscious. During the Middle Ages, sapphires symbolized the tranquility of the heavens and wearing them was thought to bring peace, happiness and purity of the soul. The color blue became the symbol of the union between a priest and the heavens, so sapphires came to be adorned on the rings of bishops. Soldiers wore them to prevent capture by enemies and kings wore the gemstone to defend against harm and put themselves in divine favor. This supposed “divine favor” is why sapphires were often the gemstone of choice for high priests and royalty throughout history. In fact, the British Crown Jewels contain a number of notable sapphires.
Today, sapphires are still believed to hold special powers. The stone is said to provide healing properties for mental illness and depression. It can be considered an aid to psycho kinesis, telepathy and clairvoyance, while providing spiritual enlightenment and inner peace. White sapphires, like diamonds, are considered the guardians of love, enhancing it and ensuring fidelity in marriage. The most powerful type of the gem is said to be the star sapphire. They are believed to protect against negative energy and have a calming effect that allows the mind to experience tranquility, joy and clear thinking.
Chrome diopside, also called Russian diopside, offers an intense forest green color. Because it is the most affordable gemstone with a pure, rich green color, many jewelry designers predict chrome diopside will be the world’s leading emerald substitute by the end of the decade. It is mostly available in smaller sizes, with the rare larger sizes becoming much more expensive and too dark. A 26.17ct oval cut chrome diopside may be the largest known example of the faceted stone, but there is also a 25.33ct stone that is brighter and more intense in color.
Chrome diopside is relatively soft, with a hardness of 5.5 on the Mohs Scale. Mostly mined in Yakutia and Siberia, the liberalization of the economy of the former Soviet Union has made chrome diopside more available, and more popular, than ever before.
