Amethyst

Posted by Joel Low on

Amethyst is by far and away one of the most popular crystals that people have today, many people around the world have a piece of Amethyst as a specimen, jewellery, thumb-stone, tumbled stone etc.

Amethyst is a Silicon Dioxide with traces of Iron. In other words and rather prosaically amethyst is a purple quartz. Amethyst belongs to the Quartz Group of Minerals. Amethyst was used in jewellery in Ancient Egypt but it is believed that the greek phrase "a-methystos", meaning not drunk was given to this crystal, because the colour of the wine at the time was purple.

Amethyst occurs in as many colours of purple that you can imagine, from a very pale lilac to a deep dark purple with red lights within. Amethyst is generally abundant. When exposed to sunlight for extended periods amethyst may fade in colour. 
Amethyst crystals do not get very large, crystals longer than 30cm are very rare. 
It is found in various forms and shapes, the most common growth forms are: 
  • Druzy, crystal aggregates that outline cavities; the crystals are usually short-prismatic and often lack prism faces.
  • Scepters are found on other colour varieties of quartz.
  • Split-growth crystals.
  • Individual well-formed crystals in small cavities and fissures. 
  • Vein filling, often with several growth phases with variable color that cause a banding pattern. ​

NOTABLE AMETHYST LOCATIONS

  • Vera Cruz, Mexico - very pale, clear, prismatic crystals that are sometimes double terminated. Crystals are typically phantomed, having a clear quartz interior and an amethyst exterior. Some are sceptered and phantomed. 
  • Guerrero, Mexico - dark, deep purple, prismatic crystals that radiate outward from a common attachment point. Often the crystals are phantomed having a purple interior with a clear or white quartz exterior. These are some of the most valuable amethysts in the world. 
  • Minas Gerais and Rio Grande do Sul, Bahaia, Brazil - crystals form in druzy crusts that line the inside of sometimes large volcanic rock pockets called geodes. The crystals that form are usually light to medium in colour and only coloured at the tops of the crystals.
  • Thunder Bay, Canada - a distinct red hematite inclusion just below the surface of the crystals is unique to this locality. Clusters are druzy crusts that line the fissures formed in ancient metamorphic rocks. 
  • Uruguay - crystals are dark to medium and form in druzy crusts that line the inside of geodes. The crystals are usually colored throughout.
  • North Carolina, USA - Druzy clusters that have a bluish-violet tint. 
  • Pennsylvania, USA - druzy clusters that filled fractures in metamorphic rocks. They are generally a brownish purple and patchy in color. 
  • Colorado, USA -- druzy clusters form crusts inside of fissures in sandstone, often on top of a crust of green fluorite. Crystals are dark but rather small. 
  • Ural Mountains, Russia - a very clear and dark variety that is cut for fine expensive gemstones, natural uncut clusters are rarely on the market. 

CHAKRA ENERGY AND AMETHYST

​Amethyst is particularly stimulating to the Third Eye and Crown Chakras.
  • The Third Eye Chakra, also called the Brow Chakra, is the center of your perception and command. It directs your sight and everyday awareness of the world. You relate to yourself through the third eye chakra. When the third eye chakra is in balance your thoughts and internal communications are healthy and vibrant. An open and balanced third eye chakra opens you to new ideas, dreams, and visions, and can control the flow of energy within all the chakras.
  • The Crown Chakra is your gateway to the expanded universe beyond the physical body. It controls how you think, and how you respond to the world around you. It connects you to the higher planes of existence and is the source of universal energy and truth. When the crown chakra is in balance then all your energies are in balance.
