Silver Jewellery with Gemstones , Gemstones O-Z
ONYX - In jewellery design as in fashion, colours look crisper against a background of black, and black and white always looks right. In fine jewellery, the black backdrop is often supplied by onyx, a black chalcedony quartz with a fine texture . Read more at http://www.gemstone.org/gem-by-gem/english/onyx.html
OPALS - All of Nature’s splendor seems to be reflected in the manifold opulence of fine Opals: fire and lightenings, all the colours of the rainbow and the soft shine of far seas. Australia is the classical country of origin. Almost ninety-five per cent of all fine opals come from the dry and remote outback desserts .

PIETERSITE was discovered by Sid Pieters in 1962 while he was prospecting some farmland in Namibia, Africa. After his discovery, he registered the find in the mineral records of Britain. His discovery was published in 1964, and the material was named pietersite. Currently there are only two known sources of pietersite; China and Africa.

RHODOCHROSITE - is a manganese carbonate mineral with chemical composition MnCO3. In its (rare) pure form, it is typically a rose-red color, but impure specimens can be shades of pink to pale brown. The streak is white. Read more at http://en.wikipedia.org/wiki/Rhodochrosite
ROSE QUARTZ is a type of quartz which exhibits a pale pink to rose red hue. The color is usually considered as due to trace amounts of titanium, iron, or manganese, in the massive material. Read more at http://en.wikipedia.org/wiki/Rose_quartz
RUBIES are precious stones and a member of the corundum family (Al2O3). Rubies range in color from the classic deep red to pink to purple to brown. Rubies are extremely hard; only diamonds are harder. During the renaissance, people thought that rubies could counteract poison. Laboratory-produced rubies were created in the 1890's; they are difficult to distinguish from natural rubies. The biggest ruby in the word is the Raviratna, which weighs 3,600 carats. Rubies have a hardness of 9 and a specific gravity of 3.9 - 4.1. Rubies are found in Afghanistan, Australia, Brazil, Cambodia, India, Myanmar (Burma), Malagasy Republic, Malawi, Pakistan, Sri Lanka (Ceylon), Tanzania, Thailand, United States, and Zimbabwe (Rhodesia).
SAPPHIRES - Blue is the main colour of the sapphire. Blue is also said to be the favorite colour of some 50 per cent of all people, men and women alike. We associate this colour, strongly linked to the sapphire as it is, with feelings of sympathy and harmony, friendship and loyalty.

SERAPHINITE (or Serefina), also known by the name Clinochlore, is a common member of the Chlorite Group of minerals. Clinochlore derives its name from the Greek "klino" meaning "oblique" or "inclined" and "chloros" meaning "green" as it is commonly colored deep forest green to green-black with inclusions of silvery Mica. Seraphinite, is derived from the Latin word "seraphin" referring to the first order of angels. The allusion to angels is due to the feathery wing patterns made by the silvery Mica contained within the stone. The Mica inclusions exhibit a chatoyancy, giving Seraphinite a wavery sheen, much like Charoite. Seraphinite forms through the metamorphic and hydrothermal alterations of other iron and magnesium silicate minerals. It crystallizes in the form of foliated or granular masses and also as tabular crystals.
A Chromium-rich variety of Seraphinite, called Kaemmererite, has a beautiful bright lavender to crimson color. The mineral Chamosite is an Iron-rich variety of Seraphinite. Seraphinite is mainly found near the Bratsk and Lake Baikal region of eastern Siberia, Russia, and has become a much sought after stone in the world of metaphysics and mineral collecting.
SMOKY QUARTZ is another macrocrystalline variety of Quartz. . The transparent brown, gray or black color makes Smoky Quartz easily recognizable. The range of "smoky" colors found in this crystal come from clear Rock Crystal Quartz which contains traces of aluminum and where the crystal has been subjected to natural radiation over long periods of time. Sometimes specimens are artificially irradiated and collectors who prefer natural occurrence should be wary of this when purchasing. Faceted specimens placed in jewelry have been misleadingly called Smoky Topaz.
Smoky Quartz most often occurs in Quartz veins where it forms inside rock cavities called "vugs". It is also commonly found in the cores of pregmatites, and more rarely as a secondary crystal within geodes. It is not unusual to find small cavities inside a Smoky Quartz crystal which contain carbon dioxide or water and sometimes both. These are called enhydros. When movement of the gas and liquid inclusions within a cavity can be seen with the naked eye, they are called elestial enhydros. When a substantial number of fluid inclusions occur in abundance, the Quartz becomes opaque and is called Milky Quartz. You will find that most Smoky Quartz crystals will form on a bed of Milky Quartz, one grading into the other. Other common mineral inclusions that may be found in Smoky Quartz are Hematite, Chlorite or Goethite.
Smoky Quartz has also been called "Champagne on Ice". It is the national gem of Scotland, and their national scepter contains a large Smoky Quartz crystal on top. Hardness: 7 , Specific Gravity: 2.65
SNOW FLAKE OBSIDIAN/ GOLD SHEEN OBSIDIAN. Obsidian is a very shiny natural volcanic glass. When obsidian breaks it fractures with a distinct conchoidal fracture. s. Obsidian is produced when lava cools very quickly. The lava cools so quickly that no crystals can form. Read more at
SODALITE is a rich royal blue mineral widely enjoyed as an ornamental stone. Although massive sodalite samples are opaque, crystals are usually transparent to translucent. Read more at : http://en.wikipedia.org/wiki/Sodalite
TANZANITE is an extraordinary gemstone. It occurs in only one place worldwide. Its blue, surrounded by a fine hint of purple, is a wonderful colour. Thanks to its unusual aura and the help of the New York jeweller's Tiffany, it has rapidly become one of the most coveted gemstones in the world.

TURQUOISE is an opaque, blue-to-green mineral that is a hydrous phosphate of copper and aluminum, with the chemical formula CuAl6(PO4)4(OH)8•4H2O. It is rare and valuable in finer grades and has been prized as a gem and ornamental stone for thousands of years owing to its unique hue. In recent times turquoise, like most other opaque gems, has been devalued by the introduction of treatments, imitations, and synthetics onto the market, some difficult to detect even by experts .

UNAKITE was first discovered in the United States in the Unakas mountains of North Carolina, unakite is an altered granite composed of pink orthoclase feldspar, green epidote, and generally clear quartz. It exists in various shades of green and pink and is usually mottled in appearance. Read more at : http://en.wikipedia.org/wiki/Unakite
