6.71 Ct. Bi Color Ametrine from Ceylon (Sri Lanka)

From the hidden folds of Ceylon, Sri Lanka, where ancient geology and tropical light conspire to color the earth, this bi color ametrine began its long, patient journey. Miners working rich alluvial deposits found a piece of rough that showed a promise of two worlds in one, a single crystal that hosts both amethyst and citrine zones in harmonious balance. At The Natural Gemstone Company we trace that story with respect, bringing the rough to master cutters who read the stone like a map. The cutter saw the potential for a long, elegant form and shaped it to an emerald cut, faceted to honor both the calm depth of the purple and the warm sparkle of the yellow. The result is a transparent 6.71 carat gem, measuring 19.00 by 8.28 by 5.05 millimeters, with intense color, eye clean clarity when examined at eye level, and an excellent polish, all enhanced by careful heat treatment that deepened and stabilized its tones without compromising the gem's natural character.

The emerald cut amplifies the ametrine’s story by creating broad, open facets that let its bi color nature breathe. Step cuts emphasize the plane where color shifts from violet to golden honey, and the long table invites contemplation, the kind you feel rather than merely see. This stone’s clarity allows light to travel with calm, drawing attention to the interplay of color rather than hiding it behind internal features. The excellent polish adds a silky mirror on each facet, so when the gem is viewed from different angles it reveals seams of color that seem to move like sunlight filtered through tea. Originating in Ceylon, Sri Lanka, this ametrine carries with it the island’s legacy of gem cutting and trade, a history that reaches through centuries into the hands of today’s artisan. Heat treatment has been applied to enhance color stability and depth, a common, well understood process that allows the stone to wear its two tones with confidence.

This ametrine lends itself beautifully to customization in many jewelry settings, and at The Natural Gemstone Company we enjoy helping clients translate its narrative into wearable art. For a ring, an emerald cut is perfectly suited to a classic solitaire set high in prongs to maximize light, or to a protective bezel for daily wear. A halo of fine white diamonds can emphasize the color division, while a double halo with mixed metals can create contrast that highlights the bi color nature. For a modern feel, an east west mounting places the stone horizontally across the finger, offering a contemporary silhouette. As a pendant the long form becomes a pendant drop that travels with motion, capable of being framed by a delicate pavé bail or set in a minimalist bar that shows the full length of the gem. In earrings, a pair of similarly cut stones could make dramatic drops, while this single gem can anchor an asymmetrical design with a complementary accent stone. It is also an exceptional choice for bespoke pieces such as a signet style cufflink top, a centerpiece for a custom bracelet, or an artful brooch, where the two tones can be balanced with filigree or geometric metalwork.

When you choose this ametrine from The Natural Gemstone Company you are choosing a stone with a narrative that moves from the alluvial beds of Ceylon to the skilled hands of a cutter, and finally into a custom design that reflects your taste and life. Our design consultation process guides you through metal choices including warm yellow gold that complements the citrine tones, romantic rose gold that deepens the purple, or cool platinum and white gold that contrast and brighten both colors. We can discuss settings that protect the gem for everyday wear, or designs that allow it to shine for special occasions, alongside suggestions for side stones and metal finishes.
