9.90 Ct. Ametrine from Ceylon (Sri Lanka)

This exceptional, one of a kind 9.90 carat, fancy shape bi color ametrine by The Natural Gemstone Company measures 18.33 x 16.30 x 7.67 mm, and is a rare statement gem for the collector who seeks distinction and exclusivity. Cut in a refined step cut, this transparent gem displays an eye clean clarity when evaluated at eye level, intense color saturation and an excellent polish that together create a hall of mirrors effect unique to stepped faceting. Originating from Ceylon, Sri Lanka, and gently heat treated to optimize its tonal balance, this ametrine presents a dramatic, naturally divided palette of golden citrine and regal amethyst that is as deliberate as a bespoke work of art. There is only one of this exact weight, cut and color split available through The Natural Gemstone Company, making it an invitation to join an elite circle of owners who appreciate the nuance of rarity and the assurance of a singular possession.

How this stone performs under light reveals its true personality, and for a connoisseur the experience changes with every environment. In bright daylight and direct sunlight the step cut throws bold, crisp flashes and the intense color intensity reads with maximum contrast, the golden zone singing like warm honey while the purple tip deepens to a vibrant royal hue. Under cool LED or gallery lighting the purple tones tighten and the gem’s facets deliver a precise, almost architectural reflection, ideal for a modern, minimalist setting. In incandescent or warm ambient light the citrine side blooms into a softer, richer gold, and the amethyst takes on a velvety, deeper tone, lending the gem an elegant, vintage appeal. In low light and candlelight the stone becomes intimate, the step facets creating subdued flashes and a glowing internal warmth, while backlighting or diffused light emphasizes its transparency and accentuates the color zoning as a soft gradient. Because of the excellent polish and the thoughtful step faceting, this ametrine maintains a commanding presence in any mounting, whether showcased as a bespoke ring, a bespoke pendant, or held as a collector’s treasure, and owning it from The Natural Gemstone Company is to claim an object of proven rarity and timeless allure.
