15.39 Ct. Purple Amethyst from Ceylon (Sri Lanka)

This specimen is a transparent purple amethyst weighing 15.39 carats, presented in an elegant oval shape with precise dimensions of 17.84 x 15.59 x 9.46 mm, supplied by The Natural Gemstone Company. The gem is faceted using a mixed brilliant cut that balances a scintillating crown with a well proportioned pavilion, yielding both depth and surface brilliance. Color assessment registers an intense saturation that remains evenly distributed across the table and facets, and clarity is graded eye clean when examined at normal viewing distance. The surface finish is described as excellent polish, and the piece has received no enhancement, preserving its natural character and original material integrity. The stated origin is Ceylon, Sri Lanka, a locale known for producing amethyst with strong color and good crystalline quality. These objective specifications position the stone as a notable example of high quality amethyst suitable for connoisseurs seeking natural, untreated gems.

The mixed brilliant faceting on this oval amethyst has been executed to emphasize both color and light performance. The combination of pavilion facets and crown facets typical of a mixed brilliant encourages internal reflections that animate the intense purple body color without compromising transparency. The cut presents a broad table that allows a clear view into the interior, facilitating observation of its eye clean clarity and even color zoning. The polish quality enhances facet junctions, enabling crisp flashes of violet and ultramarine tones as the stone is rotated under directional light. With a height of 9.46 mm and an overall silhouette close to proportional balance, the gem exhibits a commanding face up presence that reads larger than many stones of similar weight due to thoughtful facet layout and optimized depth. These characteristics make it especially desirable for collectors who prioritize optical performance alongside color saturation.

Provenance from Ceylon provides context that collectors and curators value, as Sri Lanka has a long history of supplying gem material with stable, identifiable color characteristics. The absence of enhancement is an important attribute for a high end collection, because it preserves natural state and documentation of origin. At 15.39 carats the piece crosses a threshold where both rarity and display impact increase, particularly for eye clean amethyst with intense color. For presentation in a private cabinet or museum style display, the oval format adapts well to standard settings or bespoke mounts that maintain visibility of the table and pavilion. For collectors considering wearable presentations, the gem can be set as a centerpiece in a ring or pendant design where secure bezel or prong settings will protect the girdle while allowing the table to present its full color range. The combination of size, color intensity, and natural origin meets criteria commonly used by advanced collectors to identify pieces that enhance a curated collection.

Care and documentation recommendations for this amethyst reflect its role as a high value natural specimen. Routine cleaning with warm soapy water and a soft brush will preserve surface polish, and sudden thermal shocks should be avoided to maintain structural stability. For long term storage, a padded compartment that prevents contact with harder stones is advisable. The Natural Gemstone Company can provide high resolution images, independent evaluation notes, and provenance information to support cataloguing and insurance appraisal. For mounting, experienced lapidary or jewelry artisans should confirm setting dimensions to accommodate the precise measurements of 17.84 x 15.59 x 9.46 mm and to protect the girdle. With its transparent body, intense purple color, eye clean clarity, mixed brilliant faceting, and natural Ceylon origin, this 15.39 carat oval amethyst represents a refined and enduring addition to a high end gemstone collection, suitable for both display and careful wearable commissions.
