6.13 Ct. Greenish Blue Sapphire from Ceylon (Sri Lanka)

There are gemstones, and then there are singular treasures that arrive so rarely they must be seen to be believed. This exceptional greenish blue sapphire weighs 6.13 carats, and it is fashioned into a radiant cut that measures 10.45 x 8.37 x 6.67 mm, a proportion that balances presence with elegance. Its clarity is described as very slightly included when evaluated at eye level, which means that under ordinary viewing conditions the stone reads as transparent and pristine while retaining the natural character that collectors value. The color is intense, a saturated greenish blue that shifts with movement and light, and the polish is excellent, delivering a surface finish that sings with every turn. Importantly this sapphire is entirely natural, with no enhancement, and it hails from the storied gem fields of Ceylon in Sri Lanka, an origin revered for producing sapphires that combine pure color and provenance. At The Natural Sapphire Company we present it as more than an object, it is an invitation to join an elite group of connoisseurs who recognize that the rarest gems are defined not only by carat weight but by the subtle marriage of cut, clarity, color, and origin.

When set beside more common gemstones this Ceylon sapphire reveals the qualities that make it remarkable. Many aquamarines and blue topazes offer a lovely pale tone and a crystalline clarity that pleases the eye, however they often lack the depth and saturation that confer presence and versatility in fine jewelry. Similarly, mass market heated sapphires can display bright surface color but often sacrifice the velvety depth that a natural, unenhanced stone can provide. This sapphire sets itself apart through its intense saturation and its radiant cut. The radiant cut is an artful choice for a stone of this hue because it combines faceted brilliance with broad planes that emphasize color depth, producing flashes of light that live within the gem rather than merely skimming across the surface. Unlike a diamond, which is prized for its dispersion and white light brilliance, this sapphire’s allure is chromatic brilliance, a glowing inner light of color that captures the eye in a different, more emotive way. Its very slightly included clarity means that light is allowed to interact with tiny natural features, creating delicate scintillation and a sense of life that perfectly complements its excellent polish. The absence of heat treatment or other enhancement amplifies its rarity, because unenhanced Ceylon sapphires of this size and quality are scarce, and they retain a purity of character that many collectors and designers prize above laboratory altered alternatives.

Owning this sapphire is an act of exclusivity, a choice to possess something seldom offered and effortlessly distinguished. At 6.13 carats it commands attention whether set as the centerpiece of a bespoke ring, an elegant pendant, or a tailored piece of high jewelry, and its dimensions translate beautifully into settings that showcase its color while protecting its pavilion. For a client who seeks a jewel that reads simultaneously as an everyday talisman and a museum quality specimen, this stone answers that brief with confidence. We at The Natural Sapphire Company curate such pieces because we understand that true rarity is about provenance and integrity as much as it is about visual beauty, and we are available to advise on settings that will enhance the stone’s natural strengths, from warm metals that bring out its green notes to cooler palettes that highlight the blue. This sapphire is not merely an acquisition, it is a legacy, and opportunities to claim an untouched, intense Ceylon sapphire of this size are limited. For those who wish to step into an exclusive circle of collectors and wearers, viewing can be arranged, and our team will guide you through the considerations that make this gem a wise and singular choice, a stone destined to be admired now and treasured for generations to come.
