How Gemstones are Formed

HOW GEMSTONES ARE FORMED

The majority of gemstones are formed by metamorphism. This is when minerals are forced together under great pressure and heat usually by tectonic plates moving underneath each other. The minerals are forced together and they metamorphose into different minerals, sometimes without melting. The difference between Precious stones and semi-precious. Precious stones distinquished by their quality, their rarity and the beautiy of their colors. There are only four precious stones: diamonds, spphire, ruby and emerald. All other stones are therefore called semi-precious stone.

Some of the Semi-Precious Stones we use to make the bracelets:

AGATE

Agate is a common rock formations, consisting of chalcedony and quartz as its primarly components, consisting of a wide variety of colors. Agates are primarily formed within volcanic and metamorphic rocks. The ornamentsl use of Agate dtes back to Ancient Greece in assorted jewelry and in the seal stones.

AMAZONITE

A green to bluish green to greenish blue gem material that is made into cabochons, beads and tumbled. Also known as amazonstone. Is cut and used as a gemstone. Named after the Amazon River of South America. Named to its resemblance in color to the green of the tropical rain forest.

AMETHYST

Is a purple variety of quartz and owes its violet color to irradiation.

Impurities of iron and some ases other transition metals and the presence of other trace elements, which result in complex crystal lattice substitutions.

AQUAMARINE

Named after the color of sea water. Aquamarine is the blue-green member of the beryl family. It is a hardy stone. Cleaning your Aquamarine often can keep it beautiful and shining. To clean, wash it with warm soapy water and avoid doing anything that will damage the stone. Rinse in warm water and dry immediately.

BLOODSTONE

A dark green variety of chalcedony adorned with a splatter of bright red. Has been a popular gem for at least 2,000 years. It is a Cryptocrystalline Quartz. The inclusions of Chlorite, Amphibole and Pyroxone are thought to contribute to the green base colors of bloodstone. The splashes of red are concentrations of iron oxide minerals – most likely hematite. This is mined and cut in India. Bloodstone forms at shallow depths and low temperatured by precipitation from sillica rich groundwaters in fractures and cavities

CORAL

Coral is not a mined stone or mineral but an organic gemstone. It is the hardened skeleton shaped result of scretions continuelly deposited by marine polyps. It looks like a colourful underwater plant, but it is actually a priceless gift from the sea.

CHINESE CRYSTAL

Chinese Crystal is of lower quality than brand name Swarovski Crystal or Czeck Preciosa Crystal. It is well priced and beautiful in adding to jewelry pieces. In the Chinese culture crystals are used in yoga, feng shui, healings and more

FRESH WATER PEARL

Cultured Salt Water Pearls are more expensive than cultured Fresh Water Pearls because the salt water oyster typically only produces one pearl at a time. Frcan produce up to 30 pearls at a time. Chinese Fresh Water Pearls are more affordable, longer lasting and come in a wider variety of colors than its cousin, the salt water pearl. Fresh water pearls have a thick nacre layer which gives the a beautiful lustre and shine.

HOWLITE

Howlite is a borate mineral found in sedimentary rock. It was first discovered in Canada in 1868 by Henry How, a Canadian Chemist, Mineralogist and Geologist.

Howlite, a calcium borosilicate hydroxide, is a borate mineral found in evaporite deposits. White, colorless.

JASPER

Jasper is an opaque chalcedony that comes in wide variety of colors. The term “jasper” itself comes from the Greek work Jaspi meaning “spotted stone”

Jasper is a variety quartz that may contain up to 20 percent foreighn materials or inclusions, including organic material and mineral oxides which determin the color, pattern and appearance of the stone

LAPIS LAZULI

Lapis for short, is a deep-blue meta morphic rock used as a semi-precious stone that has been prized since antiquity for its intense color . It is not a mineral like other gems.. It is a rock composed of multiple minerals. The blue color of Lapis Lazuli is mainly derived from the presence of lazurite, a blue silicate mineral of the sodalite group.

LAVA

Is a molten rock. It is created deep beneath the earth’s surface where temperatures get hot enough to melt rock. Scientists call this rock magma when it is underground. Eventually some magma makes its way to the earth’s surface and escapes via a volcanic eruption. Once this happens the magma begins to flow. This is called lava. Rocks are formed from the magma that cools and solidifies within the earths crust. When the magma solidifies this way, it cools slowly forming coarse textured rocks

Care of lava jewelry, as all gemstone. Lava jewelry can be a diffuser/aromatherapy by placing a few drops of your favorite essential oil and let it dry

MALACHITE

Is a copper carbonate hydroxide mineral. This opaque, green-banded mineral crystallizes in the monoclinic crystal system.

MOONSTONE

Is a sodium potassium aluminium silicate of the feldspar group that displays a pearly and opalescent schiller. An alternative name is Checotalite. Comes grey, white, orange, pink, green, blue, purple, yellow, brown. Pearly lustre, translucent, transparent

OBSIDIAN

Is a naturally occurring volcanicglass formed as an extrusive igneous rock. Obsidian is produced when felsic lava extruded from a volcano, cools rapidly with minimal crystal growth. It is commonly found within margins of rhyolitic lava flows known as Obsidian flows. Deep blackish green, smooth glassy

RHODOCHROSITE

Is a manganese carbonate mineral with chemical composition of MnCO2. In its pure form, it is typically rose=red color but impure specimens can be shades of pink to pale brown.

RHODONITE

Is an inexpensive pink gemstone. It often has impurities of black manganese oxide dendrite veins, creating interesting formations and providing a nice contrast. The name Rhodonite derived from the term rhodos which is Greek for “rose colored”

ROSE QUARTZ

Rose Quartz is a quartz that gets its name from it delicate pink color, ranging from light pink (almost white) to meium dark pink. It is generally cut into beads and cabochon. The pink color attributed micrscopic inclusions of pink variety of the mineral dumatrienite. It is abundant, commom and found large quantities at numerous locationsall around the world.

SUNSTONE

Oregon sunstone is a variety of labradorite that frequently displays a stunning aventurescence, or “glowing” or “glittery” schiller effect, caused by copper inclusions.

TIGER’S EYE

Tiger’s eye (also called tiger eye) is a chatoyant gemstone that is usually a metamorphic rock with a golden to red-brown colour and a silky lustre. As members of the quartz group, tiger’s eye and the related blue-coloured mineral hawk’s eye gain their silky, lustrous appearance from the parallel intergrowth of quartz crystals and altered amphibole fibres that have mostly turned into limonite.

Gems are usually given a cabochon cut to best display their chatoyance. Red stones are developed by gentle heat treatments. Dark stones are artificially lightened to improve colour using a nitric acid treatment.

Honey-coloured stones have been used to imitate the more valued cat’s eye chrysoberyl, cymophane, but the overall effect is often unconvincing. Artificial fibre optic glass is a common imitation of tiger’s eye, and is produced in a wide range of colours.

TOURMALINE

Is a crystalline silicate mineral with a chemical compounded with elements such as aluminium, iron, magnesiu, sodiumlithium or potassum. This precious gemstone can be found in a wide variety of colors. Transparent

TURQUOISE

Turquoise is a blue to gray-green mineral consisting of copper aluminum phosphate. … The mineral turquoise is formed by a chemical reaction which occurs when water containing specific minerals such as copper and aluminum leak through a rock. It forms in veins, which later then turn into a clump of turquoise.
