3.56 Ct. Ametrine from Ceylon (Sri Lanka)

This 3.56 carat cushion shape bi color ametrine from The Natural Gemstone Company is executed with technical precision, exhibiting dimensions of 11.80 x 9.03 x 5.60 mm that yield an elegant presence on the finger. The cutter employed a mixed brilliant cut protocol, combining a brilliant facet arrangement on the crown with more controlled pavilion facet geometry to optimize both scintillation and light return. Facet junctions are crisply defined and symmetry is carefully managed, producing strong contrast between flash and contrast facets that enhances perceived depth and liveliness. The excellent polish results in mirror smooth facet surfaces, allowing internal light pathways to remain undisturbed and maximizing the gemstone response to directional light sources.

Color is presented as a true bi color field, with medium light color intensity transitioning between amethyst purple and citrine yellow tones, the zoning exhibiting clean demarcation without harsh banding. The heat treated enhancement has been applied to stabilize and subtly intensify the color split, while preserving transparency and the natural pleochroic tendencies of the material. Clarity is graded as very very slightly included evaluated at eye level, which in practical terms yields an eye clean appearance under typical viewing conditions, allowing the mixed cut to perform with minimal distraction from inclusions. The cushion outline and proportions maintain an attractive spread for weight, and the relatively shallow pavilion depth produces generous table reflection that emphasizes the bi color contrast when viewed face up, while edge and crown facets refract secondary flashes that animate the color transition when rotated.

From every angle the piece demonstrates how meticulous craftsmanship enhances inherent material beauty, the precise facet geometry delivering controlled light leakage and targeted brilliance that showcases both the purple and yellow zones. The flawless finish and attention to facet alignment translate into consistent sparkle, and the combined effect of the mixed brilliant cut and excellent polish produces a lively stone that remains elegant and wearable. Origin recorded as Ceylon Sri Lanka, this heat treated ametrine is a technically refined example for connoisseurs who value measured cutting decisions, clean clarity at eye level, and a balanced color split presented by The Natural Gemstone Company.
