1.14 Ct. Greenish Blue Sapphire from Australia

From a remote Australian deposit where sunlight and ancient geology conspired to create color, this greenish blue sapphire began its journey deep in the earth, forming over millions of years as aluminum and trace elements aligned within corundum crystals. Our miners, guided by local knowledge and careful stewardship, recovered a transparent crystal that revealed promise from first sight, a promise we honored at every stage. At The Natural Sapphire Company we inspected and selected this piece for its purity and its vivid color intensity, and after a careful heat treatment to enhance its innate tone, master cutters shaped it into a 1.14 carat cushion, measuring 6.97 by 5.42 by 3.30 millimeters, with a step cut that preserves weight while delivering a sophisticated table of light. The sapphire carries a clarity grade of very slightly included evaluated at eye level, and it has been given an excellent polish, qualities that translate into a gem that feels both ancient and freshly alive when set into a design.

It is the sapphires internal structure that gives its sparkle an uncommon character, the corundum crystal lattice produces a high refractive index and strong dispersion, and when light meets those precise planes the result is a brilliance and fire that feels both deep and vibrant. The step cut plays with that structure differently than a brilliant cut, creating broad, luminous flashes and a hall of reflective planes that emphasize the stones saturated greenish blue, while subtle pleochroic behavior reveals different facets of blue and green as the gem moves, a private performance of color. The excellent polish allows each facet to act like a mirror, and the very slightly included clarity means the eye reads uninterrupted color and light, with inclusions that serve as proof of natural origin rather than distraction. From the Australian pit to the artisan bench and finally to a cherished setting, this cushion step cut sapphire is a conversation between geology and craft, and a piece The Natural Sapphire Company is proud to present for those who seek a gem with a story, an exceptional structure, and a sparkle that is unmistakably its own.
