5.13 Ct. Amethyst from Ceylon (Sri Lanka)

From the heart of Ceylon, known to many by its modern name Sri Lanka, this amethyst began its life deep within ancient metamorphic rock, shaped by time and the slow chemistry of the earth. Local miners, working with generations of knowledge, carefully extracted rough crystals from pockets where silica rich fluids cooled under pressure, allowing vibrant purple tones to crystallize. In the villages where these stones are found, amethyst has long been woven into stories of protection and clarity, and this particular crystal carried with it that quiet legacy when it traveled from the mine to our cutters. The Natural Gemstone Company values those hands and histories, and we document provenance because a gem is more than color and carat, it is a moment captured from the earth, refined by human care.

At our cutting studio the rough gained new life as a precise asscher octagon, a cut chosen to honor the crystal symmetry and to create a play of step facets that leads the eye inward. The finished gem weighs 5.13 carats, and measures 10.06 by 10.02 by 7.76 millimeters, a size that sits beautifully as a statement ring center or as a focal solitaire pendant. Its clarity was evaluated at eye level as very slightly included, which means it reads as clean to the unaided eye while retaining the character that tells of natural formation. The color presents at medium intensity, a true purple that balances depth with brightness, and the stone is transparent, allowing an elegant dance of light through its asscher facets. The polish is excellent, each facet smoothed to reveal crisp reflections and a satiny glow from the pavilion to the table. To enhance its natural beauty, the stone has undergone stable heat treatment, a commonly accepted enhancement that deepens tone and evens color without compromising integrity. When held to daylight, the gem shows lively internal flashes, with step facets and signature asscher corners creating a geometric brilliance that changes with every turn of the wrist.

For the discerning collector seeking a jewel that joins provenance with precision, this amethyst is an exceptional addition to a high end collection. Its origin in Sri Lanka offers an appealing story for connoisseurs who value geographic character, and its asscher octagon form gives it a heritage of Art Deco elegance that translates effortlessly into modern settings. Whether set in platinum for a cool, contemporary contrast, or framed in warm 18 karat gold to deepen the purple, the proportions lend themselves to bespoke craftsmanship, and the 5.13 carat weight provides presence without overwhelming delicate settings. At The Natural Gemstone Company we curate gems with an eye for rarity and wearability, and this stone sits at the intersection of both. We recommend certification for collectors who archive provenance, and we are happy to assist with independent grading upon request, to document the clarity, dimensions, and the fact of heat enhancement for complete transparency. This amethyst is not merely an object of beauty, it is a conversation piece, a link between Sri Lankan geology and the atelier that fashioned it, a refined touch that will elevate any serious gemstone collection. If you seek a gem that marries natural origin, careful cutting, and elegant potential for setting, this transparent 5.13 carat asscher octagon amethyst will become a defining element in your collection, and The Natural Gemstone Company stands ready to guide you through selection, certification, and bespoke mounting to ensure the gem wears for generations with both story and splendor.
