Quartz is one of the most common minerals found on the surface of the Earth.
Quartz has the chemical formula SiO2 and a hardness of 7 on the Mohs´scale (mineral hardness). This natural form of silicon dioxide is found in an impressive range of varieties and colours, which occurs in nearly all types of igneous, metamorphic and sedimentary rocks.
Rock crystal, rose quartz, smoky quartz, milky quartz, citrine and amethyst all belong to the quartz family.
Rock crystal is the purest of these; its name derives from Krustallos, the Greek word for ice, as the stone was originally thought to be a type of ice created by gods.
Rose quartz is a pink to reddish pink variety. It tends to be cloudy, and certain varieties produce a star effect when cut as a cabochon.
Smoky quartz is the brown to gray variety
Milky Quartz is the cloudy white variety.
Citrine is a yellow to orange gemstone variety that is rare in nature but is often created by heating Amethyst. At higher temperatures, the yellow becomes darker.
Amethyst is the purple, lilac, and mauve gemstone variety. Amethysts were thought to induce a sober mind. The name is derived from the Greek word amethystos, which means “against drunkenness”.
Crystal healing is an ancient art. It works on the principle that certain crystals give off powerful, much-needed energy for the body.
One way to connect with the healing energy of quartz is to wear a crystal next to your skin.
Some people use crystals as a charm and place them at an entrance, living room, bathroom, or bedroom according to the Feng shui. Feng shui is the ancient Chinese practice of placement and arrangement of space to achieve harmony with the environment.
