0.66 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire began its story deep within the ancient soils of Ceylon, Sri Lanka, where heat and pressure over millions of years coaxed aluminium and traces of iron and titanium into a crystal of uncommon clarity. Miners who know the rivers and old alluvial beds collected rough stones with practiced hands, sorting by weight and color before the gem made its long journey to experienced cutters. The name Ceylon has been whispered for centuries among gem lovers for good reason, because the island has a gift for producing sapphires with an open, lively blue that catches the light in a way few other origins can match. This particular stone arrived at our workshop as a small, transparent rough, promising more than its size might suggest. From the moment we first saw its potential, we imagined it becoming a piece that commands attention without shouting, a quiet declaration of taste and provenance.

Every facet of this gem was shaped with that vision in mind, by cutters trained to balance brilliance and depth while preserving the natural character of the stone. The result is a round shape weighing 0.66 carat, with exact dimensions of 4.73 by 4.71 by 3.76 millimeters, and a mixed brilliant cut that combines the scintillating fire of a brilliant pavilion with the refined symmetry of a well executed crown. At eye level the stone is graded slightly included, which means that its internal features are present but do not detract from the gem s transparency or allure when worn, and its polish is excellent so light moves through the facets cleanly. The color has a medium intense intensity, that ideal place where blue is vivid and alive, without becoming too dark. Perhaps most importantly for collectors who value authenticity, this sapphire has no enhancement, so the hue and character you see are entirely natural, an unaltered expression of Ceylon s geology and the gem s own crystalline story.

What makes this stone especially suited to a statement piece is the way size and clarity work together to project presence. At 0.66 carat the proportions are compact yet impactful, and when set as the focal point of a solitaire ring the 4.73 millimeter diameter sits proudly on the hand, large enough to catch glances yet elegant enough to wear every day. The slightly included clarity grade adds an honest personality to the gem, tiny internal markers that tell of its natural formation and that actually deepen the perception of depth under the surface. With an excellent polish and the reflective dynamics of a mixed brilliant cut, the sapphire throws flashes of blue that change in different light, creating movement and life. For those who desire a piece that reads as a statement without exaggeration, this gem is an ideal candidate, whether mounted in a minimalist bezel to highlight the color, cradled in a classic four prong setting to maximize sparkle, or surrounded by a halo that amplifies its presence without obscuring its origin.
