Zircon
Gemstone : Birthstone Month : Zodiac : Chemical Symbol : Chemical Make-up : History & Lore : An interesting fact about Zircon is that geologists can determine how long a certain stone has existed by using modern analytical techniques. This is possible because Zircon crystals accumulate atoms of Uranium which decay to lead at a known rate. Zircon is so far the oldest mineral known to man, with the oldest specimens to date being found in Western Australia (4.404 billion years old), and Chile (4.6 billion years old). Colorless Zircon specimens have long been a popular substitute for diamonds. This is because of Zircon's high refractive index, luster, and light dispersion. Today Zircon is often overlooked, probably due to its name being similar to the synthetic, man-made Cubic Zirconia, also a diamond substitute. In the middle ages, Zircon was believed to aid sleep, promote honor, and to bring prosperity and wisdom to its wearer. |
| Availability : Sources : Evaluation : For many years, colorless Zircon was the most popular variety. This was due to it's striking resemblance to the Diamond. Today however blue Zircon is the most popular color. Blue Zircon is found in pastel blue and occasionally bright blue. Zircon is also available in green, dark red, yellow, golden-yellow, brown, and orange colors. Zircon has a very high refractive index meaning it has the ability to strongly bend light, in fact, it is strikingly similar to that of the diamond, explaining why it has been a popular substitute. Zircon also has a beautiful luster and a high light dispersion that accounts for the stone's beautiful “fire”. Zircon is found in both a low and a high variety. The two varieties are separated by their difference in refractive index and specific gravity. The “high type” naturally has a higher refractive index and specific gravity than the “low type”. The differencea are a result of the decay of Uranium and Thorium, elements that are naturally present in Zircon. The radioactive decay from the Uranium and Thorium causes the crystal structure of the low type to break down over millions of years. Fortunately, heat-treatment can reverse much of this deterioration and to convert low type into high type stones. Common Cuts : Routine Enhancements : Care & Cleaning : Zircon jewelry should always be stored in a fabric-lined box away from other jewelry items to avoid chipping and scratching. |
Yellow Tourmaline
Gemstone: Yellow Tourmaline Birthstone Month: Zodiac: Chemical Symbol: Chemical Make-up: History & Lore: Tourmaline is often referred to as the rainbow gemstone, due to the huge amount of colors that it is available in. This was certainly believed by the ancient Egyptians who believed that when Tourmaline traveled from its home in the earth's core to the surface, it did so along a rainbow, which subsequently gifted the gemstone with all of the colors of the rainbow. Tourmalines exhibit piezoelectricity and when these stones become warm they become electrically charged – positively at one end and negatively at the other, acting like a magnet and strong enough to attract small particles of dust or ash. It is for this reason that the Dutch of old used Tourmalines to clean their pipes! |
| As with most gemstones, ancient civilizations credited Tourmaline gems with magical and mystical powers, including having the power to guard against danger and misfortune. Tourmalines are said to have an especially strong influence over friendship and love, lending permanence and stability to both. Tourmaline gems help to amplify psychic ability / energy and are an excellent aid to increasing self-confidence and understanding. Tourmaline is believed to help assist with tranquil sleep, calm nerves, improve concentration and creative processes and to be an aid to curing cancer. Yellow Tourmalines are believed to activate the solar plexus chakra which can in turn enhance personal power and intellectual pursuits. In addition to this, Yellow Tourmalines are said to bring heightened intelligence, creativity, initiative, and spiritual awareness. Availability: Sources: Evaluation: Found in an amazing variety, the sheer number of available Tourmaline colors is second to none and unmatched by any other gemstone. Tourmalines can be found in shades of blue, black, brown, colorless, green, orange, pink, red, yellow and other colors in varying shades and hues, varying from completely transparent to opaque. In addition to this there are also known occurrences of bi-color, tri-color, mulit-color and “Cat's Eye” Tourmalines, ensuring that the Tourmaline truly is a gemstone that is available in a color to suit all styles and tastes. A Tourmaline gemstone viewed from different angles will result in differing color intensities being visible. The only one thing that you can be sure of is that the deepest coloration will always be shown along the stone's main axis. When selecting a Tourmaline, go with the color that you like but generally try to steer clear of any stone that is cut too dark. Yellow was formerly the missing color that was needed to complete Tourmaline, the “Rainbow Gemstone”. Although yellow Tourmalines were being mined, most displayed a brownish tinge that greatly decreased their overall value and desirability. Then in the autumn of 2000, rumors surfaced that beautiful yellow Tourmalines had been discovered in Malawi, a country located south of East Africa. The rumors were in fact true, and bright yellow colored Tourmalines soon became offered in the market. Yellow Tourmalines offer a pleasant lemon yellow color with an occasional fine greenish hue. The Malawi deposits will also occasionally have a brown undertone but will most often be removed through both the heat-treatment process and by the cutter. Another unique and interesting characteristic about Yellow Tourmalines is their fine scent. This scent is of course not natural and can't be enjoyed by the wearer but instead by the cutter who fashions the stone. This is because when Tourmalines are mined they are often found embedded in black material which will need to be removed before the stone can be cut. An owner of one Malawi mine discovered that the black material can be removed quite effortlessly by boiling the stones with a little lemon juice. Because of this interesting experiment, cutters can enjoy the fresh scent of these stones well fashioning them. Common Cuts: Routine Enhancements: Care & Cleaning: |
