5.03 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 5.03 carat cushion shape blue sapphire from Ceylon is a quiet celebration of centuries of gem cutting and royal taste, offered by The Natural Sapphire Company. Measuring 9.61 by 8.84 by 6.55 mm, the stone is cut in a mixed brilliant pavilion and crown that balances classic proportions with modern faceting, and it is transparent with a clarity grade of very slightly included when evaluated at eye level. The medium intense blue color is true to the storied Sri Lankan palette, and because this sapphire is completely unenhanced it carries the authentic character and natural depth prized by collectors and connoisseurs. The excellent polish and the cushion outline recall historical cuts once set in heirloom jewels, and the gem wears its legacy with a refined presence whether set in a solitaire ring or a more elaborate period style mounting. Photographs show the sapphire seated on a finger for scale, and the way it catches light gives a sense of both its physical size and its living color.

In reflection and brilliance this Ceylon sapphire performs in a manner distinct from many other gemstones in its category. The mixed brilliant cut maximizes return of light and scintillation, producing flashes that are more lively and dispersed than the flatter, velvety look of some step cut sapphires, while retaining the depth and saturation that historical Sri Lankan stones are known for. Compared to spinel and tanzanite, this sapphire displays stronger light return and a firmer, more crystalline luster because corundum has a higher refractive index, and unlike aquamarine and topaz it maintains color intensity without looking washed out under strong light. Against heated or heavily treated stones the unenhanced Ceylon gem shows a more natural, layered reflection with subtle internal movement rather than uniform saturation. When placed beside diamonds it will not mimic diamond fire, but its blue flashes and scintillation convey a noble, timeless glow that has been admired across generations. For someone seeking a historic sensibility combined with excellent optical performance, this sapphire presents a rare balance of provenance, untouched color, and lively reflection that still feels at home in both antique inspired and contemporary jewelry designs.
