Amethyst

Amethyst

Amethyst is a captivating gemstone renowned for its enchanting purple hues and historical significance. As a variety of quartz, its name derives from the Greek word “amethystos,” meaning “not intoxicated,” reflecting ancient beliefs in its sobering properties.

Variety and Category

• Mineral Family: Quartz (Tectosilicate)
• Chemical Formula: SiO₂ (Silicon Dioxide)
• Crystal System: Trigonal
• Mohs Hardness: 7

Amethyst’s durability makes it suitable for various types of jewelry, and its trigonal crystal structure contributes to its distinct appearance.

Color and Value

Amethyst exhibits a spectrum of colors from light lavender to deep violet. The most prized specimens display a strong reddish-purple to purple hue with no visible color zoning. The coloration results from trace amounts of iron and natural irradiation within the quartz structure.

The value of amethyst is influenced by several factors:

• Color: Deep, saturated hues are more valuable.
• Clarity: Stones with higher transparency and fewer inclusions command higher prices.
• Cut: Precision in cutting enhances the stone’s brilliance and color display.
• Carat Weight: Larger stones are rarer and thus more valuable.

Notably, the “Deep Siberian” variety is renowned for its intense purple color with blue and red flashes.

Optical Properties

• Luster: Vitreous
• Refractive Index: 1.544–1.553
• Birefringence: 0.009
• Pleochroism: Weak to moderate; varies with color

Amethyst’s brilliance and transparency make it a favorite among gem enthusiasts. Its relatively high refractive index contributes to its sparkling appearance when properly cut.

Common Cuts and Applications of Amethyst

Jewelers typically facet amethyst into shapes such as oval, pear, cushion, and emerald cuts to maximize its brilliance. They commonly use it in various types of jewelry, including rings, earrings, pendants, and bracelets. Due to its good hardness, it is suitable for daily wear.
