4.36 Ct. Ametrine from Ceylon (Sri Lanka)

One exceptional gemstone from the heart of our collection at The Natural Gemstone Company is a transparent 4.36 carat asscher octagon shape bi color ametrine, with precise dimensions of 9.71 x 9.52 x 7.99 mm, a cut that marries geometric clarity with a soft, living color story. This stone has been masterfully faceted in the asscher style to reveal step facets and a luminous table, it carries a clarity graded as very very slightly included when evaluated at eye level, and it displays a medium light color intensity that lets both warm citrine tones and cool amethyst violet speak without one overpowering the other. The polish is excellent, producing crisp light return and a mirror like finish across the facet planes. The gem has been heat treated, a disclosed enhancement used to refine and stabilize the bi color zoning, and its origin is identified as Ceylon, Sri Lanka, a name that evokes centuries of gem lore and maritime trade. This combination of weight, cut and provenance makes the stone immediately distinctive, suitable for a headline ring or a pendant that will be admired for generations.

To truly appreciate how this ametrine can become an heirloom, it helps to consider the lineage of the asscher cut and the long standing reputation of Ceylon as a source of fine gems. The asscher cut rose to prominence in the early twentieth century, celebrated for its bold symmetry, deep pavilion, and hall of mirrors effect that rewards careful viewing. An asscher cut lends itself to jewelry that reads both modern and timeless, evoking Art Deco refinement while remaining perfectly at home in the most classic of settings. Ceylon, historically known as a nexus of gem trading across the Indian Ocean, contributes its own narrative to the gem, a story of skilled miners, careful cutters, and centuries of treasure seekers. When a gem carries such a resonance of place and craft, it moves beyond immediate fashion into the territory of legacy, an object that links the owner to a far reaching history each time it is worn.

The ametrine itself is a rare and poetic union of two identities in a single crystal. Where amethyst offers violet depth and introspective coolness, citrine brings sunlit warmth and buoyant gold, and in this particular 4.36 carat gem the transition between tones is both harmonious and arresting. The asscher cut has been chosen to emphasize this duality, its concentric step facets creating planes that catch the two colors in changing proportions as light and angle shift. Because the stone is transparent with very very slight inclusions at eye level, the visual effect is clean and clear, allowing the bi color zoning to be read at a glance while also yielding subtle surprises as the gem turns. The disclosed heat treatment is a common and accepted practice, applied thoughtfully to enhance and stabilize the natural color zoning so that the gem will endure as a jewel to be loved rather than one to be altered repeatedly. The Natural Gemstone Company curates each ametrine with this philosophy in mind, favoring cuts and finishes that honor the stone rather than obscure its natural beauty.

Turning a remarkable gem into a generational heirloom requires both thoughtful design and practical care, and this ametrine is well suited to both. Quartz family gems, which include ametrine, rate seven on the Mohs scale, giving them a dependable resistance to daily wear while still calling for sensible protection in active situations. For a lasting legacy piece consider settings that protect the girdle and pavilion, such as a low profile bezel for everyday elegance, or a vintage inspired prong setting with a protective gallery for a ring that speaks of ceremony and style. For those who wish to craft an heirloom with narrative depth consider pairing the ametrine with side stones that echo its duality, such as warm champagne diamonds or cool lavender sapphires, or commission an Art Deco inspired mounting that will align the gem with the historical language of the asscher cut. Personal touches such as an engraved date or family initials, a custom leather lined presentation box, and a documented certificate of origin and treatment from The Natural Gemstone Company will provide provenance and sentimental weight. Routine care is straightforward, gentle cleaning with warm soapy water and a soft brush, avoidance of strong chemicals or prolonged high heat, and professional inspection of the mounting from time to time to ensure that settings remain secure.

A gemstone that arrives from Ceylon with a story already attached becomes, when set with intention, a vessel for family stories to accumulate. Imagine the ametrine worn at milestone ceremonies, photographed across decades, and then passed to a child who learns the names and meanings behind the stone and the family who first chose it. The asscher faceting will continue to reward inspection, revealing new planes of light to a new generation just as it revealed them to the first wearer. At The Natural Gemstone Company we believe that true heirlooms are crafted from more than raw beauty, they require provenance, skilled finishing, and guidance so that the piece will be both cherished and preserved.
