Description
Faceted Amethyst Crystal from Madagascar
This Faceted Amethyst Crystal from Madagascar is a polished natural mineral specimen carved from amethyst, the purple variety of quartz. The stone has been cut with multiple polished facets to highlight the natural colour, clarity, and internal structure typical of this quartz variety. The faceted finish allows light to reflect across the surfaces of the crystal, enhancing its natural colour and giving the piece a striking display appearance.
Amethyst is recognised for its distinctive purple tones, which can range from pale lavender to deeper violet shades depending on the concentration of trace elements and the geological conditions present during formation. The polished facets accentuate these colour variations and help reveal the natural internal textures formed during crystal growth.
The photograph in this listing shows the exact specimen you will receive, allowing buyers and collectors to clearly view the colour, polish, and natural features of the stone prior to purchase.
This crystal is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card.

Mineral Identification – Amethyst Quartz
Amethyst is a variety of quartz, one of the most abundant minerals in the Earth’s crust. Quartz belongs to the silicate mineral class and is composed primarily of silicon dioxide.
Key mineralogical characteristics include:
-
Mineral Name: Quartz
-
Variety: Amethyst
-
Chemical Formula: SiO₂ (Silicon Dioxide)
-
Mineral Class: Silicate
-
Crystal System: Trigonal
-
Mohs Hardness: 7
-
Lustre: Vitreous
-
Transparency: Transparent to translucent
The purple colour of amethyst results primarily from trace amounts of iron within the crystal lattice combined with natural irradiation during geological processes.
Geological Formation of Amethyst
Amethyst commonly forms within volcanic rock cavities and hydrothermal mineral veins. As silica-rich fluids circulate through fractures and cavities in the host rock, quartz crystals gradually grow over time. In certain conditions where iron impurities are present and natural radiation affects the crystal lattice, the quartz develops the purple coloration characteristic of amethyst.
Typical geological environments where amethyst forms include:
-
Basaltic lava cavities and geodes
-
Hydrothermal quartz veins
-
Silica-rich volcanic deposits
-
Sedimentary formations containing quartz minerals
Over long geological timescales, these crystals can grow into well-formed quartz structures that are later extracted and shaped for mineral collections or decorative display.
Colour Characteristics and Natural Features
Amethyst displays a wide spectrum of purple shades, including:
-
Pale lavender tones
-
Soft lilac hues
-
Medium violet colours
-
Deep royal purple shades
Natural colour zoning may also occur, where lighter and darker purple areas form within the same crystal during growth. When polished or faceted, these variations can become more visible as light passes through the stone.
Natural inclusions, internal veils, or faint growth lines may be present within the crystal. These are typical features of natural quartz and reflect the geological environment in which the crystal developed.
Madagascar Amethyst Locality
Madagascar is recognised as an important source of quartz minerals, including amethyst. The island’s geological landscape includes volcanic and metamorphic formations that provide suitable conditions for quartz crystal development.
Amethyst specimens from Madagascar are often appreciated by collectors for their attractive colour and clarity, making them suitable for both mineral displays and polished decorative forms.
Faceted Lapidary Finish
This specimen has been shaped using lapidary techniques into a faceted form, where multiple polished faces are cut across the surface of the stone. The faceting process enhances the natural appearance of the mineral by reflecting light across the polished surfaces.
The process typically involves:
-
Cutting rough quartz material from larger mineral deposits
-
Shaping the stone into the desired form
-
Creating multiple flat facets across the surface
-
Polishing the facets to a smooth reflective finish
This style of finish highlights the crystal’s internal colour and gives the stone a refined decorative appearance while preserving its natural mineral character.
Mineral Collecting and Decorative Display
Faceted amethyst stones are popular among mineral collectors due to their combination of natural colour and polished presentation. The reflective surfaces created by faceting allow the mineral to display its colour and clarity when placed under natural or display lighting.
This specimen may be appreciated as:
-
A quartz mineral collector specimen
-
A decorative crystal display piece
-
A geological example of coloured quartz
-
A mineral-themed gift item
-
A display piece for cabinets, desks, or shelves
In some traditions, amethyst crystals are traditionally associated with symbolic or spiritual interpretations, though these interpretations are cultural beliefs rather than scientific explanations.
Authentic Natural Mineral Specimen
