8.01 Ct. Ametrine from Ceylon (Sri Lanka)

I want to take you to the quiet highlands where this stone began its life, to the mineral rich veins of Ceylon, Sri Lanka, a place where heat and pressure have written geological stories over millions of years. In those depths a crystal grew that would later reveal two distinct colors within a single crystal, the amethyst purple and the citrine yellow that together make ametrine. Every band of color is a map of changing conditions during formation, a natural record of temperature and trace elements that no laboratory can truly duplicate. At The Natural Gemstone Company we seek out these rare, naturally bicolored crystals, working with small scale miners and local cutters who respect the stone and its story. When you hold this ametrine you are holding a fragment of the earths history, a gem that first formed long before any modern process, and that carries the whisper of the place where it was born.

From rough to refined this 8.01 carat oval ametrine has been shaped with intention to celebrate its dual personality. The dimensions 13.50 x 10.58 x 9.03 mm reflect a significant size that makes it both commanding and wearable. The cutter chose a mixed brilliant cut to maximize light performance while honoring the natural color zoning, balancing faceting to catch brilliance in the yellow zones and depth in the purple areas. Clarity is very very slightly included evaluated at eye level, which means the stone reads clean to the eye while keeping natural inclusions that act like fingerprints confirming its origin. Color intensity is described as medium, allowing a gentle and elegant contrast between the two hues that shifts with movement and light. The gem has received careful heat treatment to enhance and stabilize its color, a standard practice that is openly disclosed and performed to bring out the best in a natural stone. An excellent polish finishes the work, giving the surface a mirror like sheen that plays with the internal color separation, creating flashes that are alive as you turn it in your hand.

When customers ask how this natural ametrine compares to lab grown alternatives I like to speak plainly about what each offers and why many collectors keep returning to natural stones. Lab grown gems excel in consistency, and in some cases they can be produced with very high clarity and saturated color at a predictable price. They are marvels of modern science and have their place in contemporary designs. Natural ametrine however carries a provenance, an individuality, and a narrative that is inseparable from its value. The color zoning in this Ceylon stone is irregular and complex, a pattern that developed under conditions unique to its crystal. Those subtle transitions, the way purple fades into yellow in a manner that changes with lighting and angle, are extremely difficult to recreate in a lab. Natural inclusions serve as a record of growth and environment, tiny signatures that tell a gemologists trained eye about origin and journey. There is also a cultural and emotional layer, the idea that a gem has spent geological epochs forming beneath the earth in a particular place, and that it has been responsibly sourced and shaped into a wearable jewel rather than manufactured.

Imagine this ametrine set as a ring, resting on the hand as shown in our photos, or mounted as the center of a pendant where light can dance through both colors. At 8.01 carat and with an oval outline that measures 13.50 x 10.58 x 9.03 mm the stone is versatile enough for a dramatic solitaire or for a refined halo setting that complements rather than competes with its natural zoning. The mixed brilliant cut and excellent polish make it sparkle in both warm and cool light, while the disclosed heat treatment ensures color stability for years of wear.
