Turquoise Necklace

The turquoise is ancient, yet again and again it finds itself back in fashion. Its shining sky blue is one of the most popular trend colors in the world of jewelry and fashion

In many cultures of the Old and New Worlds, this gemstone has been esteemed for thousands of years as a holy stone, a bringer of good fortune or a talisman. It really does have the right to be called a 'gemstone of the peoples'. The oldest evidence for this claim was found in Egypt, where grave furnishings with turquoise inlay were discovered, dating from approximately 3000 B.C.. In the ancient Persian kingdom, the sky-blue gemstones were earlier worn round the neck or wrist as protection against unnatural death. If they changed color, the wearer was thought to have reason to fear the approach of doom. Meanwhile, it has been discovered that the turquoise certainly can change color, but that this is not necessarily a sign of impending danger. The change can be caused by the light, or by a chemical reaction brought about by cosmetics, dust or the acidity of the skin. A good reason to buy only stabilized Turquoise, which doesn't change for any reason.

Turquoise is a copper aluminium phosphate with a hardness of 6, i.e. considerably softer than quartz. In Nature, it occurs in the whole range of hues from sky blue to grey-green, and it is mostly found in places where there is a high concentration of copper in the soil. However, turquoise is only really turquoise in the very best quality; mostly, the color is paler, or bluish-green or greenish. The blue color is created by copper, the green by bivalent iron and a certain amount of chrome. Often, the material has veins or blotches running through it, which are brown, light grey or black depending on where it was found. These lively, more or less regular patterns are known as 'turquoise matrix'. The crystals are microscopically small and can hardly ever be recognized with the naked eye. As a rule, turquoise occurs as a fillung in veins or crevices, or in the form of nuggets. The most well known deposits are in the USA, Mexico, Israel, Iran, Afghanistan and China. The most beautiful turquoises, in a splendid light blue, come from deposits in the north of Iran.
Turquoise is rarely faceted. Usually, it is cut into cabochons or beads, or into some more imaginative shape.

Wax makes turquoise more resistant Being relatively soft, turquoises are sensitive. As the color may pale when the stone has been worn for a long time, even high-quality recognized stones today are treated with wax and subsequently hardened. This treatment makes the sensitive gemstone more resistant. In the trade, there are a large number of reasonably priced turquoises sealed with synthetic resin. They have a fresh color and good durability. And there is also such a thing as a 'reconstructed turquoise', which is made from pulverized turquoise.

Because of their sensitivity, turquoises are almost always subjected to treatment of one kind or another, though this may take any of a number of different forms. For this reason, turquoises which have a good natural color and are simply hardened with colorless wax or synthetic resin have a much higher value than stones whose color has been 'improved'.

  Amethyst Nugget Pendant



Amethyst is the purple variety of quartz and the most valued member of the quartz family. It must be purple to be amethyst, but it can display a range of shades including deep purple, light lilac, lavender and mauve. Top quality amethyst is a deep medium purple with rose-colored flashes. Its purple color made it a stone of royalty for many thousands of years.

Amethyst can occur as crystals that are six sided on either end. It also forms as drusy which are crystalline crusts covering the host rock. It is found inside geodes and in alluvial deposits all around the world and occurs in both crystalline or massive forms. When manganese is present in clear quartz amethyst is produced, while the amount of iron contained in the specimen accounts for the depth of purple.

Mohs scale of hardness is 7.

Hardness is measured using the Mohs Scale of Hardness. A substance's hardness value indicates the materials resistance to scratching and grades minerals on a comparative scale from 1 (very soft) to 10 (very hard).. In the Mohs scale, a mineral of a given hardness rating will scratch other minerals of the same rating, as well as any minerals of a lower rating. For example, sapphires and rubies have a Mohs rating of 9 and will scratch each other, as well as any mineral with a rating lower than 9. However, they will not scratch diamonds, which are rated 10. The Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs (1773-1839) in 1812.
Most amethyst gemstones on the market today are heat-treated to produce a deeper color. Heat treating is permanent and these stones will not fade over time and is not only common but accepted worldwide.

Unless otherwise stated, assume that any amethyst you purchase today has been heat treated to increase the depth of color.

Throughout history amethyst has been used and is thought to be helpful in overcoming addiction. It has been used for hearing disorders, insomnia, headaches and other pain. Some sources suggest it is used to stabilize mental disorders.

Worn to make the wearer gentle and amiable. Amethyst powers include: dreams, healing, peace, love, spiritual uplift, courage, psychism, protection against thieves, and happiness.

 Lapis Lazuli is listed as the traditional birthstone for December. (Note that the official birthstone list adopted by the American National Association of Jewelers in 1912 denotes Turquoise and blue Topaz as the official birthstones.) It is also the Planetary stone for Capricorn and the birthstone for Libra. See the birthstone tables for additional references to lapis. Lapis may be given as a gem on the 7th and 9th wedding anniversary.

Lapis is considered a rock, not a mineral. It combines various minerals, mostly lazurite, but also contains calcite (white), sodalite (blue) and pyrite (fools' gold, a metallic yellow) and to be considered a mineral it would have only one component.

Top quality lapis lazuli comes from Afghanistan where is has been mined for more than 6000 years, but is also found in Siberia, Chile, the U.S., Pakistan, and Canada. A strong blue, sometimes with a hint of violet, lapis lazuli's value decreases with the presence of white patches (calcite), while small veins of pyrite are often prized.

The Egyptians used Lapis for seals, ground it for an eyelid cosmetic and often carved it into vases and figurines. A soft stone, 5 -5.5 on the Mohs scale of hardness, lapis lazuli is one of the most valuable semi opaque stones.

Strengthens total awareness, creativity, ESP, skeleton, thyroid, helps to expand viewpoint. It is believed to improve sleep and cure insomnia. The Romans used lapis as an aphrodisiac.

During ancient times lapis was ground up and used for medicinal purposes as well as a cosmetic. The ground powder was mixed with milk and used as a compress to relieve ulcers and boils and, during the Middle Ages, lapis lazuli was believed to maintain the skeleton in healthy condition while keeping the spirit free from the negative emotions of fear and jealousy.

Lapis is used to energize the throat chakra and when placed over the brow chakra it induces a heightened state of awareness.
