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.
Iolite gets its name from its sensational color, using the Greek words ios (violet) and lithos (stone). The stone, often referred to as water sapphire, cordierite or dichroite, was used by the Vikings as a navigational tool and came to be knows as “Vikings’ Compass.” When Viking explorers ventured far into the Atlantic Ocean, away from any coastline that could help them determine position, they were able to navigate safely by looking through iolite lenses that allowed them to find the exact position of the sun.
The property that made iolite so valuable to the Vikings was the gem’s pleochroic property, which is the display of different colors when viewed from different directions (like a modern-day polarized filter used in sunglasses). A cube cut from iolite will look violet-blue from one side, clear as water from the other and honey yellow from the top.
Pleochroism may have been helpful in navigation, but it makes a gem cutter’s job quite difficult. If iolite is not cut from exactly the right direction, its color will not show to its best advantage. When cut properly, the stone is usually a violet blue and can be obtained in sizes up to 5.00 carats relatively easily. Iolite ranks a 7.0-7.5 on the Mohs Scale and is readily available and affordable. Today, it is mined in Brazil, India, Mozambique, Sri Lanka and Zimbabwe. The Vikings probably mined iolite from deposits in Norway and Greenland.
Traditionally given as a 21st anniversary gift, iolite is thought to bring harmony to relationships. It is also said to balance the masculine and feminine aspects of one’s own character, bringing harmony and enabling that person to enjoy each moment. Iolite is believed to heighten psychic abilities by aiding and encouraging people along their spiritual paths. It is said to enhance curiosity and achievement, and aid in money management. Iolite is also believed to possess the power to guide lost sailors to the brilliance of the sun, so that they may find their way home.
Often referred to as the “Queen of Garnets,” rhodolite is the violet-red variety of the garnet family. Its most prized color is a beautiful raspberry, but the gem can also be found in shades of pink, red and wine. The name is derived from the Greek words “rhodon” and “lithos,” meaning rose-stone, which connects the gemstone today with the raspberry-pink flower known as the rhododendron.
Rhodolite is a combination of almandine and pyrope garnets. Although it is occasionally found in volcanic rock, the stone is most often found in alluvial deposits in the form of water-worn pebbles. For this reason, large solitaires weighing 5.00ct or more are seldom seen at retail. Most rhodolite is mined in Sri Lanka, Tanzania and Zimbabwe. It ranks a 7.5 on the Mohs Scale and is ideal for jewelry.
The ancients wore rhodolites as amulets for protection from injury or death in battles. Modern folklore says rhodolite can help one understand dreams, as well as bring about love and devotion when given as a gift.
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.
