loose amethyst available to purchase

Amethyst is the birthstone for February and the gem for zodiac sign Aquarius, the gemstone for the 6th and 17th wedding anniversaries.

Amethyst has been a treasured gem since antiquity and is included in royal collections all over the world.  For centuries amethyst was valued even higher than rubies and sapphires and only worn by royalty or by the clergy as a symbol for the deity of Christ.  Amethyst exclusivity changed when vast deposits of amethyst were found throughout the Americas, particularly in Brazil in South America.  Now the beauty of amethyst is available to all.

Ancient Greeks and Romans believed that the stone protected the wearer from the intoxicating powers of Bacchus,  keeping the wearer clear-headed and quick-witted.  Believed to block angry or uneasy emotions amethyst is associated with qualities such as peace, stability, courage,  strength and holiness.

The semi-precious gemstone Amethyst is a purple variety of quartz.  Like many other quartz its attractive colour, durability and the affordability make it very popular.  Amethyst has a hardness of 7 on Moh’s scale.

Amethyst crystals occur in a wide range of sizes and large carat gems are readily available.  As a result price per carat does not rise dramatically for larger sizes.

Much of the faceted amethyst in the market is eye-clean, meaning it lacks eye-visible inclusions and any inclusions will decrease its value.   Amethyst can be carved, custom-cut, or calibrated for jewelry use.  Amethysts with eye-visible inclusions but attractive color are usually cut as cabochons or beads.

Amethyst ranges from a very light pinkish violet to a deep purple and occurs from transparent to translucent.  It can fade in tone if overexposed to light sources.  The value of amethyst is primarily defined by depth of colour.  The finest amethyst color is a strong reddish purple or purple with no visible colour zoning.  The paler the colour or the more visible the zoning of lighter and darker purple colour, the lower the value.

In Bolivia, amethyst and citrine occur in the same crystal. Called ametrine, these crystals are half purple and half yellow.

Quartz is the chemical compound, silicon dioxide or silica.  It is the second most abundant mineral in Earth’s continental crust, a component in granite, sandstone, schist and shale to name a few.

Pure quartz, traditionally called rock crystal is colourless and transparent or translucent.  The coloured varieties of quartz occur due to built-in trace elements or inclusions of other minerals.

With a hardness of 7 on the Mohs scale, many forms of quartz are used as gemstones, and they are all affordable. They are cut into various gemstone cuts and cabochons, and used in all forms of jewelry.  The wide range of colour, lack of cleavage and good durability and wide availability combine to make quartz is a very popular semi-precious gemstone option.

Gemstone varieties are divided into two main groups:
  • Varieties that develop visible crystals or are made of large inter-grown crystals. They tend to be transparent to translucent and include Amethyst, Citrine, Smoky quartz, Rose quartz, Green quartz, Rutilated quartz and Adventurine.

  • Any form of Quartz composed of tiny crystals that cannot be seen with an unaided eye. Known as Chalecedony they tend to be translucent to opaque and include multi-coloured Agate, Carnelian, Tiger’s Eye, Chrysoprase, Onyx and Jasper.
