12.98 Ct. Purple Amethyst from Ceylon (Sri Lanka)

This listing describes a single transparent purple amethyst weighing 12.98 carats, cut in a classic emerald shape and presented in a faceted cutting style. The stone measures 15.35 x 12.58 x 10.58 mm, and it displays an intense purple color with strong saturation and even tone across the table and pavilion. Clarity is graded as very slightly included when evaluated at eye level, providing a clean appearance to the naked eye while retaining natural characteristics when viewed under magnification. The polish is excellent, producing crisp facet junctions and a refined surface that contributes to bright reflections and defined internal light play. This specimen is natural and untreated, with no enhancement, and it originates from Ceylon, Sri Lanka, a source renowned for producing high quality amethyst material.

The emerald cut proportions and faceting of this amethyst emphasize color and clarity in a way that suits both classic and contemporary jewelry designs. The long step facets and trimmed corners create broad flashes of even color, while the pavilion faceting supports depth and a controlled return of light rather than a highly scintillating effect. This geometry is particularly well suited to settings that feature the stone as the primary visual element, including solitaire rings, elegant pendants, and bespoke cocktail pieces. At 12.98 carats and with its measured dimensions, the gem occupies a notable visual presence without overwhelming most mounting designs. The faceting and excellent polish together produce a surface that accepts precise metal work and secure prong or bezel settings, and that retains visual integrity under close inspection.

Sourcing for this amethyst is aligned with responsible practices that matter to conscious consumers. The piece was procured from Sri Lanka, known locally as Ceylon, through established relationships with miners and cutters who operate at a small scale. The Natural Gemstone Company works with partners who emphasize traceability, fair remuneration for local workers, and minimal environmental disturbance in extraction and processing. Because this gem is natural and free of enhancement, there is no heat treatment or irradiation applied, and its origin and natural state are part of its provenance story. We document origin claims and the supply chain to the extent possible, and we encourage dialogue with clients who require additional verification or desire greater detail about sourcing practices and chain of custody. This measured approach supports collectors who prioritize ethical considerations alongside aesthetic and gemological quality.

For the collector who balances aesthetics with conscious purchasing, this amethyst offers both a strong visual statement and an ethical provenance. Its size, cut, and intense color make it an excellent focal stone for a signature piece, while its untreated natural state appeals to those who value minimal intervention. The gem performs well in everyday wearable settings when set securely, and standard care will preserve its appearance. Clean the stone gently with warm water, mild soap, and a soft brush, avoiding abrasive chemicals and prolonged exposure to strong sunlight which can affect color over long periods. The gem exhibits a Mohs hardness of 7, and while it resists everyday scratches, reasonable care is recommended to avoid impact and abrasive contact. For any repair or resizing of the mounting, consult a jeweler familiar with colored gemstones to ensure the setting retains security and aesthetic alignment. The Natural Gemstone Company is available to provide additional images, measured documentation, and guidance on setting design to help integrate this amethyst into a considered, ethically minded collection.
