Amethyst Tip Madagascar | Model 2

Size: 8.5 * 5.5 * 5 cm

Amethyst is the purple variety of quartz and one of the best known minerals in the silicate family. It is appreciated for its wide palette of shades, from lilac and delicate purple to deep purple with purple or slightly reddish tones.

From a mineralogical point of view, amethyst is made up of silicon dioxide (SiO₂) and crystallizes in the trigonal system. The characteristic purple color is related to traces of iron present in the crystal structure and natural irradiation processes which occur in the geological environment in which the crystal is formed.

Amethyst can form in cavities of volcanic rocks, where silicon-rich solutions allow crystals to grow on the inner walls. Over time, they can create spectacular geodes and amethyst druses, composed of numerous crystals oriented towards the interior of the cavity. The mineral can also appear in hydrothermal veins and in other geological contexts favorable for quartz formation.

Well-developed crystals usually exhibit prismatic shapes with natural terminations, a glassy luster, and varying degrees of transparency. A common feature is color zoning: purple may be distributed unevenly throughout the crystal, with lighter and more intense areas, sometimes concentrated toward the crystal terminations.

Inside, veils, mineral inclusions, healed fractures, and various growth patternscan be observed. These elements formed along with the mineral and represent part of its geological history.

Mineral: Amethyst
Variety: Quartz
Composition: SiO₂ – silicon dioxide
Crystal system: Trigonal
Hardness: 7 on the Mohs scale
Luster: Glassy
Transparency: Transparent to translucent
Color: Lilac, purple, purple-purple to deep purple

The color, transparency, zoning, inclusions, and shape of the crystals naturally differ from one specimen to another. In the case of geodes and druzes, the shape of the cavity and the distribution of the crystals are also unique.

Each amethyst specimen is a unique mineral formation, with its own particularities of color, structure, and crystallization.
