Quartz Gemstone

Quartz is the godfather of the gemstones world that has been used since prehistoric times. Quartz is the second most abundant mineral in Earth’s crust. It has got the largest family and can be found in an amazing variety of colours and varieties.

Introduction

You will find quartz stone is abundance in igneous, metamorphic, and sedimentary rocks. It is extremely resistant to mechanical and chemical weathering. Pure quartz creates colourless and transparent crystals with glass-like lustre. Quartz is famous for excellent crystals it forms in all kinds of cavities and fissures. There are two main types of gem-quality quartz. One is Macrocrystalline Quartz that is coarsely crystalline so its formations can be seen by the naked eye. The stones range from translucent to transparent and come in a wide variety of colours, like purple-violet of the amethyst and the golden yellow of citrine. Other is Microcrystalline Quartz that is smaller in size and is also known as grainy quartz or chalcedony quartz. The gems are usually opaque or translucent, and they’re formed from microscopic crystals that are invisible to the naked eye. Know more about this spectacular stone with these interesting details.

Origin and Supply of Quartz

Most prominent varieties of different shapes and colours of quartz crystals are found in hydrothermal ore veins and deposits. Large crystals originate from hot brines in huge fissures, silica-rich fluids in cavities in pegmatites, silica in Alpine-type fissures, and cavities of volcanic rocks. Well-formed quartz crystals are found in septarian nodules and also in dismissal pockets in limestones. China, Japan, and Russia are the world’s main producers of quartz. Belgium, Brazil, Bulgaria, France, Germany, South Africa, and the United Kingdom also mine significant quantities of the quartz stone.

How is Quartz Mined?

Best place to mine extract Quartz crystals in Arkansas mines. Quartz is mined from open-pit mines. Miners use bulldozers and backhoes to separate soil and clay and reveal the quartz crystal veins in the rock. Miners use explosives on rare events when they need to expose a deep joint of quartz. Mines in the Mt. Ida area, and around the city of Hot Springs allow anyone interested in finding quartz to find quartz stones.

Properties of Quartz

Quartz has a combination of certain electrical or optical properties with great physical strength and chemical resistance. Quartz crystals have piezoelectric properties that allow it to develop an electric potential upon the application of mechanical stress. The vibration frequency of the crystal is used to generate an electrical signal of very precise frequency. Quartz is a technically important material that is valued for the combination of certain electrical or optical properties with a great physical strength and chemical resistance.

1. Colour

Quartz can be found in many different colours. In its purest form, it is of transparent or white colour, but various impurities within the atomic lattice cause the colour to change to purple, pink, brown, black, grey, green, orange, yellow, blue, or red. The main crystalline Quartz varieties used as gemstones are:

Amethyst

Amethyst, the purple variety, is the most famous and valuable variety of Quartz stone. Amethyst ranges from light to dark purple.

Citrine

This variety of quartz comes in a yellow, orange, or reddish-brown colour. Light yellow or lemon yellow citrine is often called Lemon Quartz in the gem trade.

Quartz

Smoky Quartz is the brown "smoky" version of Quartz. It varies in colour from light brown to black. This stone is more of a lustrous kind then being opaque.

Rose Quartz

This type of quartz has got the beauty of rosy pink colour and known as Rose Quartz. Its colour is normally soft, varying from very light pink to medium pink in depth. Rose Quartz is often milky or opaque.

Rock Crystal

This variety of quartz is colourless, transparent and free of any impurities. Flawless and very large cuts are usually cut from Rock Crystal.

Milky Quartz

Milky Quartz is the white, translucent to opaque variety of Quartz. Though very common in nature, it is not used as a gemstone.

Rutilated Quartz

This colourless Quartz with golden yellow Rutile inclusions within the gemstone.

Ametrine

This beautiful variety of quartz is an interesting, colour-zoned combination of purple Amethyst and brownish-yellow Citrine.

Prasiolite / Green Quartz

This variety of quartz is artificially coloured by heat treatment of certain types of Amethyst.

Blue Quartz

Blue Quartz is clear rock crystal is illuminated with gold to form a deep sky blue colour. Blue Quartz can also refer to a dull greyish-blue Quartz.

Tourmalinated Quartz

This colourless variety of quartz with Tourmaline inclusions comes as thin long black crystals.

Cat's Eye Quartz

This variety if Quartz with dense and tiny Rutile inclusions cause a cat's eye effect. Cat's Eye Quartz is usually greyish in colour and translucent.

2. Lustre

Quartz has a glassy lustre, which means that it combines with light in the same way that glass does. Transparent quartz stones tend to be macrocrystalline and the different crystals can be seen with the human eye. However, translucent and opaque stones are cryptocrystalline, and the crystals are only through a microscope.

Uses of Quartz

Quartz crystals are used in electronics to transfer mechanical energy into an electrical sign or digital electrical signal into mechanical movement. They have a piezoelectric property that is widely used in electronics. Radios, Microphones, robotics, timers, clocks, buzzers, watches, and many more electronic components and devices use quartz crystals.

Healing Properties of Quartz

Clear Quartz is the most popular healing stone of all the crystals.

It is the most powerful healing stone that is known as the stone of power and said to amplify any energy or intention. It is said to protect against negativity, connecting you to your higher self.

  • Check the surface temperature of the quartz is before handling it. Good-quality quartz is cool to the touch, like glass, while a piece of plastic that resembles quartz will feel warm or room temperature to the touch.
  • Examine the colour of quartz is very important. Natural quartz has irregular striations and colour distribution.
  • Check the quartz for cracks and fissures as it is more valuable when it is completely intact. The interior body of the stone shows a glossy and colourful surface
  • Use a magnifying glass to get a close-up look at the quartz stone. The surface should be streaked with white and show naturally occurring irregularities.
