3.48 Ct. Ametrine from Ceylon (Sri Lanka)

This listing describes a transparent 3.48 carat cushion shape bi color ametrine from Ceylon, Sri Lanka, presenting dimensions of 11.46 x 9.22 x 5.58 mm, a mixed brilliant cut, eye clean clarity as evaluated at eye level, medium color intensity, and an excellent polish. The stone exhibits the characteristic duality of ametrine with a clear purple amethyst zone and a warm golden citrine zone, the transition between hues being discernible yet elegant rather than abrupt. The mixed brilliant faceting enhances light return across both color zones, preserving transparency and minimizing windowing, while the excellent polish contributes to strong surface luster. The piece has undergone heat treatment, a common and accepted enhancement that stabilizes and refines tone and hue, and it is offered by The Natural Gemstone Company with full provenance stated as Ceylon.

In direct comparison to ametrines from Bolivia, notably material from the Anahí region which is the classical commercial source, this Sri Lankan example displays a more restrained medium intensity, with softer saturation and a gentler gradation between purple and yellow fields. Bolivian ametrine often shows a more vivid and high contrast pairing of deep violet and saturated golden yellow, occasionally with sharper separation lines. Compared to Brazilian amethyst and citrine, which can present deeper, cooler violet tones or warmer, more orange leaning yellow respectively, the Ceylon ametrine here sits between those profiles, favoring a balanced purple that does not trend to blue undertones, and a citrine field that remains bright without veering into brownish orange. Relative to gemstones from other famed localities such as Sri Lankan sapphires, which are celebrated for their lively cornflower to medium blue tones and exceptional clarity, this ametrine shares the high clarity expectation and refined cut, while its hue family and optical behavior remain distinct.

This specimen will suit a collector or jewelry designer seeking a moderately saturated bi chromatic stone with refined cutting and eye clean clarity, appreciating a subtler palette than the bolder Bolivian examples, and a provenance that combines Sri Lankan gemological tradition with careful treatment and finishing.
