- The Complete Guide

1. Introduction


A royal gemstone with an aura of luxury and tradition, amethyst has been a popular choice among emperors and monarchs since ancient times. Regarded as the most popular purple color gemstone in the world, the word Amethyst is derived from a Greek word “amethustos”, which translates to being sober. Anciently, amethysts were known to be used to protect against drunkenness and other sicknesses.


Known as the chief member of the quartz family, Amethyst is the aubergine cousin to varieties like Citrine, Prasiolite and Rose Quartz.

2. Meaning


Gathering information from writings, books and folklore, it is believed that Amethyst not only promotes serenity, peace & relaxation but also adds a sense of personality and charisma that lures people towards its charm.

It is also believed that ancient Egyptians, Greeks and Romans valued purple amethyst to guard them against negative influences.

3. Mythology


It was believed that if a person drank from a cup or goblet made entirely of amethyst, it could prevent them from becoming drunk.

In Greek mythology, amethyst was rock crystal dyed purple by the tears of Dionysus, the god of wine and revelry.

In Renaissance magic, an amethyst engraved with the image of a bear was worn as a protective amulet and in Graeco-Roman times, rings of amethyst set in bronze were worn as charms against evil.


It was also believed that if an Amethyst is placed beneath a pillow or worn to bed, then it would produce peaceful sleep with pleasant, healing, and often prophetic dreams.

Colored by the element Iron, in combination with Silicon Oxide, the elements that make up quartz, amethyst has been a popular gemstone for generations. Mined historically in Russia, fine colored amethyst was a rare gem, until the discovery of the mines in South America and Africa.

Brazil is a popular source that produces over 70% of the amethyst today. However, most of the amethyst from Brazil is usually in lighter and pale color. A few exceptional pieces from the Uruguay region do come bursting with the intense colors as seen in an orchid.

On the other hand, mines in the region of Africa produces the most vividly colored amethysts. Zambia, a rich geological hub unearths amethysts that are immersed with deep hues to the likes of velvet. Coupled with immense saturation these amethysts evolve into some of the most spectacular purple gems known, demanding high values.

7. Buying an Amethyst Engagement Ring


Proposing with a purple amethyst engagement ring can be a perfect choice for couples seeking a birthstone engagement ring or among couples who love the deep rich color denoting luxury, glamour & tradition.


Choosing a vivid colored amethyst wisely will complement the custom setting and make the ring stand out and shine in brilliance.



Fine quality amethyst comes in a deep violetish purple to a reddish purple and can fall in any color in-between.

Amethyst is popularly cut in various shapes such as round, oval, cushion, emerald and pear. Irrespective of shape, it is important to choose an amethyst with symmetrical cuts in order to bring out it’s shine and brilliance.

Cut plays an important role for an amethyst because of the gems innate transparency. A cutter must facet it with precision in terms of height and number of facets to add the perfect blend of brilliance. This helps to keep away from a window, which would let light and color escape.
