Although many of the varietal names historically arose from the color of the mineral, current scientific naming schemes refer primarily to the microstructure of the mineral. Color is a secondary identifier for the cryptocrystalline minerals, although it is a primary identifier for the macrocrystalline varieties. [48] Major varieties of quartz The ancient Greeks believed amethyst gems could prevent intoxication, [23] while medieval European soldiers wore amethyst amulets as protection in battle in the belief that amethysts heal people and keep them cool-headed. [24] Beads of amethyst were found in Anglo-Saxon graves in England. [25] Anglican bishops wear an episcopal ring often set with an amethyst, an allusion to the description of the Apostles as "not drunk" at Pentecost in Acts 2:15. [26] The "myth" of Amethyste and Bacchus was invented by the French poet Remy Belleau (1528–1577). See "L'Amethyste, ou les Amours de Bacchus et d'Amethyste" from Belleau's collection of poems "Les Amours et Nouveaux Eschanges des Pierres Precieuses: Vertus & Proprietez d'icelles" (The loves and new transformations of the precious stones: their virtues and properties), which was published in Remy Belleau, Les Amours et Nouveaux Eschanges des Pierres Precieuses...

The relaxing vibes are anything but temporary. Unlike other methods of finding solace, Blue Quartz has an impact that goes much deeper than face value.

Amethyst is relatively common in the Canadian provinces of Ontario and Nova Scotia. The largest amethyst mine in North America is located in Thunder Bay, Ontario. [14] Until the 18th century, amethyst was included in the cardinal, or most valuable, gemstones (along with diamond, sapphire, ruby, and emerald), but since the discovery of extensive deposits in locations such as Brazil, it has lost most of its value. [37] It is now considered a semiprecious stone. [38]

Synthetic (laboratory-grown) amethyst is produced by a synthesis method called hydrothermal growth, which grows the crystals inside a high-pressure autoclave.

Major development was done during World War II, to supply crystals for radios. Today, our computer industry is based on synthetic quartz. Not that there is a shortage of natural crystals, but the synthetics are always clean and are less time consuming to trim into the necessary pieces.Most crystal practitioners seek out Blue Quartz for its rejuvenating energy that influences the mind and spirit. However, that doesn’t mean it’s devoid of physical perks. Amethyst was used as a gemstone by the ancient Egyptians and was largely employed in antiquity for intaglio engraved gems.
