Gems en Vogue Sleeping Beauty Turquoise & Pink Tourmaline Ring

Tourmaline:
Tourmaline occurs in virtually every color of the spectrum, with an unlimited range of solid and mixed colors in all imaginable shades. According to an ancient Egyptian legend, this is the result of the gemstone traveling along a rainbow from the Earth's heart, up to the sun. On its journey, the legend says that tourmaline collected all the colors of the rainbow, which is why it is called the "Rainbow Gemstone."

The gem is found in hues of red, pink, green, blue, yellow, black, brown and colorless. It also can be bi-colored or multi-colored. Some tourmalines are very faint in color, while others are so dark that the color is only discernible when light is shone through the stone. There are even tourmalines that change their color from daylight to artificial light.

Tourmalines displaying just one color are quite rare since one crystal usually shows two or more shades or colors. In fact, the name "tourmaline" has been derived from the Singhalese expression "tura mali," which translates to "stone of mixed colors." Even two stones cut from the same rough mother crystal will often show different colors, a characteristic that makes tourmalines so attractive and sought-after.

Tourmaline also shows a remarkable dichroism. This means that when viewed from different directions, the stone will display different colors, or at least show different intensities. The deepest color always appears along the main axis, a fact that is important for the gem cutter to focus upon when cutting the stone. Tourmalines rank a hardness of 7.0-7.5 on the Mohs Scale and may be as small as a knitting needle or as thick as a thigh. They are easily available in sizes of up to 5.00ct.

Different shades of colored tourmalines have been assigned specific names in the gemstone world. Bi-colored and multi-colored tourmalines have several names for the common combinations of colors. Crystals with red or pink cores and green borders are called watermelon-tourmalines. Stones with colorless crystals and black tips are called Maur's Head or Moor's Head, while colorless crystals with red tips are called Turk's Head. If the color zones are arranged one on top of the other, the stone is considered a rainbow tourmaline.

The red variety of tourmaline changes its name based on the coloring in different types of lighting. Deep red tourmaline named rubellite shows the same fine ruby-red shade in daylight and in artificial light. Should the color change when the source of light changes, the stone is simply called a pink tourmaline. With its exquisitely intense coloring, rubellite was once the victim of misidentification for rubies in the Russian crown jewels.

Green tourmalines come in a variety of shades, including leek-green, intense yellow-green, olive-green and brownish-green. Chromium-tourmaline is the trade name for the emerald-green variety. Its beautiful color is strikingly similar to the fine color of emeralds. Blue-green and dark bottle-green are the most rare and highly coveted green hues.

Perhaps the most beautiful variety is the Paraiba tourmaline. It ranges in color from electric blue to neon blue-green to sizzling turquoise. Discovered in the Brazilian state of Paraiba, its vivid color has not been consistently seen in any other gemstone variety. Its spectacular color is due to the presence of a small amount of copper. A study by the German Foundation for Gemstone Research also discovered a surprisingly high content of gold in the stones.

Until recently, there was one striking gap in the range of colors displayed by tourmaline. Pure yellow shades were missing and most of the yellow tourmalines that were found showed a slightly brownish tinge. In the year 2000, however, electric yellow tourmalines were found in Malawi in East Africa. With a clear and pure color, they were deemed "canary tourmalines" and the formerly missing color of yellow was added in excellent quality to the unlimited range of tourmaline colors.

Larger yellow tourmalines rarely occur. Only 10 percent of all the mined yellow stones are gem-quality and when cut, more than 95 percent of the harvest will weigh less than 1.00ct. Regardless of their smaller size, experienced cutters love working with the stones. Not only do they have brilliant color, yellow tourmalines are considered to be the only gemstones that have a fine scent. This is because in the place of their occurrence, tourmaline crystals are often embedded into black material that must be removed before the stones are cut. An owner of a Malawi gemstone mine discovered the black matter was easily removed when the rough crystals were boiled in water and lemon juice. Ever since then, yellow tourmalines from Malawi not only resemble fresh lemons in color, but also in their scent before they are cut.

Other tourmalines are called "indigolith" if they are blue and "dravite" if they are golden to dark brown. Black tourmalines are known as "schorls" and are mainly used for engraving. Although they were used as mourning jewelry, ancients believed black tourmalines to be stones that protected against negativity and strengthened the heart.

Tourmalines are piezoelectric, meaning they can generate electrical charges when heated, compressed or vibrated. They then become polarized crystalline magnets and can attract light objects. The Dutch knew about this effect and used heated tourmalines to extract ashes from their pipes. The stones were even favorite toys of Dutch children before their gem quality was established. Because the gem's electrical charges attract dust and small materials, some believe that wearing pink tourmalines will attract love and green ones will attract success.

Tourmaline has often been called the "muses' stone" because it is believed that its imaginative colors contain inspirational powers that grant enlightenment, enable creativity and express an artist's mood. Due to the stones' energetic conductivity and vast array of elements, they are thought to have powerful healing abilities and protect against many dangers. Tourmaline is supposed to be an especially powerful influence on love and friendship, fostering compassion and cool headedness. It is considered the traditional gift to give couples celebrating their 8th wedding anniversary.

Ever since the ancient days, the gem has been attributed with magical powers. Today, specific colors of tourmaline are thought to hold individualized powers. Black is believed to bring luck and happiness when rubbed. Green is said to encourage communication and bring success, while blue is a balancer that stimulates other tourmalines' effectiveness. Watermelon tourmaline is believed to increase perception and creativity, while balancing passivity and aggressiveness. Pink is thought to promote peace, increase spiritual understanding and bring forth love and friendship.

Turquoise:
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.
