All About Amethyst


Amethyst is the widely known and very popular purple form of macrocrystalline Quartz and is, in fact, one of the most valuable forms of the common mineral. Amethyst is famous for its purple color, which is caused by iron impurities within the structure of the Quartz crystal. Beyond the traditional big four ‘precious stones,’ which are Diamond, Ruby, Sapphire, and Emerald, Amethyst is probably the most recognizable and well-known type of gemstone to the general public. Amethyst is also the birthstone for February.

Etymology & Sources

The name ‘Amethyst’ is derived from the Greek word ‘Amethystos,’ which translates to ‘not drunken,’ and ancient Greeks believed that Amethysts had the ability to protect against or prevent inebriation (in our experience, it doesn’t work). Because of this, it is not uncommon to see historical wine vessels and goblets encrusted with the purple gemstone. Purple was also historically considered the color of royalty, and as such, the Amethyst was particularly popular among the nobility. Historically speaking, Amethysts were considered very rare until large supplies of them were found in deposits in Brazil around the turn of the 19th century. Nowadays, Amethysts are much more common than they were, and deposits exist in Brazil, Bolivia, Canada, Russia, and many other places.


Amethyst is purple and can range from a light, lilac color to a deep and intense purple. Amethyst can range from transparent to translucent and has a vitreous luster. The most valuable forms of the gemstone are generally the darker deep purple variety, and higher clarity is typically heavily favored. Since Amethyst is a form of Quartz, it has decent hardness suitable for many different decorative applications.

Other Properties

Amethyst has a Moh scale hardness of around 7, similar to other Quartz, and has a specific gravity of about 2.65 and a refractive index value of roughly 1.55.


Higher quality Amethyst is usually faceted into traditional gemstone shapes, but sometimes lower quality, lighter, or more translucent Amethyst is cut en cabochon or into beads – these are particularly popular with jewelry-making enthusiasts. Due to the availability of large Amethyst crystals, carvings and other ornaments can also be carved. Amethyst can also be found sold in geode form, either for decorative purposes or for those that believe in crystal healing for health reasons.


  • Amethyst Quartz – Usually a mixture of Amethyst and Clear Quartz, it is typically a mixture of a white milky color and purple. It is rarely faceted and most often formed into beads or cabochons.
  • Green Amethyst – Light green form of Quartz, where the colors are artificially created by subjecting Amethyst to heat treatment. It is also known as Prasiolite.
  • Ametrine – Natural mixture of Amethyst and Citrine that often has a clear and abrupt split between the purple Amethyst part and the yellow Citrine part. Only comes naturally from one source in Bolivia, but can also be synthetically created.


Amethyst is occasionally heat-treated to improve the intensity of the purple color. Heat treatment can also be used to turn Amethyst into Citrine, or the artificial green Quartz variety Prasiolite (mentioned above). Amethyst can also be created synthetically.

Advice to Help You Shop for Amethyst Jewelry

Amethyst is a lilac to a purple variety of quartz, its color formed from iron impurities within the stones. Royal families have identified with the deep purple gemstone for centuries, and many who love amethyst believe it possesses mystical and healing properties.

Amethyst’s color can be altered with heat treatments — the gem can be transformed into darker hues and even turned yellow to resemble citrine, another member of the quartz family. Another gemstone, called ametrine is a naturally occurring mixture of amethyst and citrine and displays the colors of both. So far, the majority of ametrine used in jewelry has been found in Bolivia.

Most of today’s amethyst jewelry is made with either heat-treated gemstones of amethyst that’s been grown in a laboratory, rather than found in nature.

What Is the Cursed Amethyst?

London’s Natural History Museum is the home of the Cursed Amethyst, sometimes called the Blasted Amethyst. The large amethyst was stolen from a temple in India in the mid-1800s and taken to England. It is the central stone in the photo to the left — click for a larger image.

Legend says that the cavalry officer who removed the gem from India became ill and lost all of his money shortly after returning to England. His son inherited the amethyst, and shortly afterwards his life changed for the worse, too. The next owner was Edward Heron-Allen, whose luck also took a downward turn after taking possession of the amethyst.

Heron-Allen decided the amethyst was cursed, and he locked it in a bank vault, out of anyone’s reach, leaving instructions that the package holding the stone not be opened until 3 years after his death. In 1943, Heron-Allen’s daughter donated the stone to the Natural History Museum, along with a note written by her father that said ‘this stone is trebly accursed and is stained with the blood and the dishonor of everyone who has ever owned it.’

The Cursed Amethyst remains in the museum’s Vault, a special display area that houses a collection of unique gems, crystals, and meteorites, including meteorites from Mars. Another special gem on display is called the Medusa emerald. Its long crystals were embedded in a ‘brick’ of quartz, and it took several months for experts to remove a portion of the covering.
