This natural rough Amethyst specimen displays a striking combination of deep purple colour, translucent crystalline zones and irregular natural surfaces that give the piece strong visual depth and mineralogical character.

The specimen shows pronounced variation between darker violet sections and clearer lavender-to-transparent areas, creating a layered appearance that changes considerably with viewing angle and lighting. Natural fractures, internal veils, inclusions and uneven crystalline textures remain clearly visible throughout the stone, preserving the authentic structure of the untreated material.

Under ultraviolet illumination, the specimen shows a visible reactive response, adding an additional point of interest for collectors and gemstone enthusiasts. The exact appearance and intensity of this reaction may vary depending on the wavelength and strength of the UV light source used.

With a weight of approximately 63 g, equivalent to 315 ct, and dimensions of approximately 64.3 × 31.5 × 26.1 mm, the specimen has an elongated form that makes it particularly suitable for display in a mineral collection, on a shelf or desk, or within a curated decorative arrangement.

Its deep purple colour and natural translucency also make it attractive for those who appreciate Amethyst within meditation or crystal traditions, while its rough unpolished appearance keeps the focus firmly on the natural geological character of the stone.

Every fracture, colour zone and surface irregularity forms part of the individuality of this natural specimen, making the exact piece shown in the photographs completely unique.
