1.76 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

From the ancient gem gravels of Ceylon Sri Lanka to your hands, this 1.76 carat oval color change sapphire tells a story written by time and geography. Deep beneath tropical soils, trace elements and heat and pressure coaxed aluminum oxide into the crystalline lattice that becomes sapphire, and generations of miners and lapidaries carried that story forward by gently coaxing the rough from its riverbeds and ridgelines. This stone measures 7.14 x 5.75 x 5.13 mm, a compact form that concentrates the gemmaker of the island into an intimate parcel of color and fire. It arrives to you as a transparent oval, vivid in color intensity, with an identity shaped by both nature and careful human hands. You will notice its color changing personality at once, a living memory of the light of its origin, shifting from cooler blue tones in fluorescent light to warmer violet and blue violet notes under incandescent illumination. The stone is heat treated to stabilize and enrich that innate color, an enhancement that respects the sapphire's natural heritage while bringing its face forward for modern jewelry applications. The clarity is very slightly included evaluated at eye level, a grade that reads as honest and close to eye clean, with minute markers of its geological voyage adding character rather than distraction, and the finish is an excellent polish that prepares it for a life on the finger or in a pendant.

The choice of a mixed brilliant cut for this oval sapphire is a conversation between brilliance and color, a thoughtful decision by our cutters to maximize the gem's light performance and its unique color change effect. The mixed brilliant combines the scintillating pavilion arrangement of brilliant cutting with a table and crown specially tuned to the oval outline, allowing light to enter through the elongated face, scatter across a symmetrical array of facets, and return in brilliant flashes that emphasize both sparkle and depth of hue. The pavilion facets act as mirrors, guiding light into the heart of the sapphire where pleochroic color zones and trace chromophores live, and then reflecting those tones back through the crown facets so that each movement reveals a new balance between blue and violet. The oval shape lengthens the visual field of color, so the mixed brilliant faceting becomes a tool to show off both intense saturation and changeable personality, concentrating flashes of white light and colored brilliance across the table, while smaller crown facets create a lively scintillation that brightens the gem against the skin. Excellent polish ensures that every facet edge is crisp, minimizing diffusion so the paths of light are clear and lively, and the result is a gem that feels animated in hand and alive on the jewelry it adorns.

When you choose this sapphire from The Natural Sapphire Company you are selecting more than a gemstone, you are adopting a small archive of place and craft that will participate in your personal story. Set in a classic bezel to emphasize the oval silhouette or in a four prong open setting to allow maximum light to enter and display the color change, this 1.76 carat gem will sit comfortably on the finger, pendant, or in bespoke designs, its dimensions making it versatile for daily wear or for a statement piece. The stone responds to light in ways that reward movement and changing environments, so imagine the cool blue flashes under daylight when commuting, then the warmer violet glow during evening hours, a living jewel that adapts to your moments. Caring for it is gentle and straightforward, a warm soapy water bath and a soft brush will restore the polish and let the mixed brilliant cut sing, and avoid sudden temperature shocks and strong acids to protect the integrity of the heat treated enhancement.
