Amethyst
Introduction to Amethyst
Amethyst is one of the world's most prized and renowned gemstones, celebrated for its magnificent violet color that ranges from pale lilac to deep purple. Belonging to the macrocrystalline quartz family, it has fascinated humankind since antiquity with its captivating beauty and relative accessibility, making it the most sought-after variety of quartz among collectors and mineral enthusiasts.
Etymological origin and discovery
The name "Amethyst" comes from the Ancient Greek word "amethystos" (ἀμέθυστος), which literally means "not intoxicated" or "protective of drunkenness." This name originates from the ancient belief that this stone protected its wearer from the effects of alcohol. Greek legend recounts that Dionysus, the god of wine, transformed the nymph Amethyst into crystal to protect her, then poured wine over the stone, giving it its characteristic purple color.
Amethyst has been known and used for over 25,000 years. The Egyptians used it to create amulets and seals, while the Romans made wine cups from it, believing it would protect them from drunkenness. In the Middle Ages, it adorned royal and ecclesiastical jewelry, symbolizing piety and celibacy. The German mineralogist Abraham Gottlob Werner (1749–1817) contributed to its modern scientific classification in the 18th century.
Mineralogical properties
Composition and chemical formula
Amethyst belongs to the macrocrystalline quartz group, in the silicate family. Its chemical formula is SiO₂ (silicon dioxide).
Its characteristic purple color is due to the presence of iron impurities (Fe³⁺ and Fe⁴⁺) in its crystalline structure, combined with natural irradiation. The intensity of the color depends on the iron concentration and the degree of irradiation it received during its geological formation.
Physical characteristics
- Hardness : 7/10 on the Mohs scale (10 for diamond), making it a hard and resistant but brittle stone.
- Density : 2.65 (1 for water)
- Crystal system : Rhombohedral (trigonal), macrocrystalline structure
- Fracture : Conchoidal
- Transparency : Transparent to translucent
- Luster : Vitreous
- Line : White
Color palette and varieties
Amethyst displays a remarkable range of purple hues:
- Lavender amethyst : Very pale violet, almost lilac-pink
- Siberian amethyst : Deep purple with red highlights, considered the most precious
- Uruguayan amethyst : Intense and deep purple, very saturated
- Brazilian amethyst : Medium to light purple, often in large geodes
- Chevron amethyst : Alternating bands of white quartz and purple amethyst in a V shape
- Ametrine : A natural combination of purple amethyst and yellow citrine in the same crystal
- Green amethyst : Prasiolite, obtained by heating amethyst (rare in its natural state)
- French pink amethyst : Delicate pink-violet hue
Caution : Prolonged exposure to sunlight can discolor amethyst. Some amethysts are also artificially heated to obtain yellow citrine or green prasiolite.
Deposits and origins
Main producing countries
The most important amethyst deposits are located in:
- Brazil : The world's leading producer, particularly in the states of Rio Grande do Sul, Minas Gerais, and Bahia (giant geodes), amethysts have large crystals
- Uruguay : Renowned for its superior quality amethysts, deep purple but with smaller crystals than those from Brazil
- Zambia : Intensely colored amethysts
- Madagascar : Wide variety of qualities and shades
- Russia : Ural Mountains, historically famous for Siberian Amethyst
- United States : Arizona, North Carolina, Montana, Colorado
- Mexico : High-quality amethysts

Amethyst in France
France has a few sites where amethyst can be found, although the deposits are modest:
- Auvergne : In the hydrothermal veins of Puy-de-Dôme and Haute-Loire
- The Vosges Mountains : Amethysts in the fissures of granite and metamorphic rocks
- Brittany : A few occurrences in Morbihan and Côtes-d'Armor
- The Massif Central : Various sites with small but very dark colored amethyst crystals
- The Alps : Alpine amethysts in the crevices of crystalline rocks
French amethysts, although generally small in size, are sought after by local mineral collectors for their authenticity and provenance.
Historical and cultural anecdotes
Historical anecdote: The British crown
One of the most famous amethysts in history adorns the British Imperial State Crown, housed in the Tower of London. This remarkable amethyst, set atop the cross that crowns the crown, measures several centimeters and displays an exceptionally deep purple color. The crown, created in 1937 for the coronation of King George VI, also contains the famous Black Prince's Ruby and the Cullinan II diamond. Until the 19th century, before the discovery of the great Brazilian deposits, amethyst was considered as precious as diamond, ruby, sapphire, and emerald, and reserved exclusively for royalty and the clergy.
Cultural anecdote: The Bishop's Ring
In the Roman Catholic tradition, amethyst has held a special place since the Middle Ages. Bishops traditionally wear a ring adorned with an amethyst, a symbol of their ecclesiastical dignity and their commitment to celibacy. This purple stone, a liturgical color associated with penance and spirituality, represents sobriety, piety, and renunciation of earthly pleasures. This tradition continues today in many dioceses around the world. Amethyst was also used to adorn chalices, pectoral crosses, and other liturgical objects, reinforcing its association with Christian spirituality.
