0.67 Ct. Greenish Blue Spinel from Ceylon (Sri Lanka)

This exquisite oval greenish blue spinel, weighing 0.67 carat and measuring 6.31 x 5.26 x 2.55 mm, arrives to you from the famed gem fields of Ceylon Sri Lanka, offered exclusively by The Natural Gemstone Company. Transparent and deeply colored, this gem immediately stands apart from the many stones on the market because it is natural, untreated, and free from enhancement. The hue is a rich greenish blue with dark color intensity, a shade that reads as sophisticated and versatile in most light, and that shifts beautifully as it interacts with ambient illumination. For collectors and designers seeking a gemstone that reads as both rare and wearable, this spinel’s balance of size, tone, and provenance places it in a category above mass-market alternatives and close to the level of fine colored gemstones traditionally reserved for higher-price brackets.

What elevates this spinel beyond color alone is the exceptional precision of its mixed brilliant cut and excellent polish. The mixed brilliant design marries the scintillating fire of a brilliant faceting pattern on the crown with a refined pavilion arrangement that maximizes light return and depth. Compared with standard step cuts or poorly executed ovals often seen at similar price points, this stone exhibits a lively play of facets that creates a dynamic surface, catching flashes of brilliance along the table and displaying a well-balanced body color when viewed face up. The excellent polish means facet junctions are crisp and surfaces are mirror-smooth, enhancing both sparkle and the perceived depth of color. For a centerpiece gem, the way it captures and returns light is as important as its hue, and this spinel’s cutting quality ensures it performs like a much larger stone visually.

Clarity and natural condition are key differentiators in this market, and this spinel’s clarity grade of very slightly included evaluated at eye level translates to an attractive and practical advantage. Under casual inspection the stone reads clean and lively, while microscopic or loupe-level inclusions are minimal and do not compromise durability or brilliance. Many gems at comparable prices may be oiled, heated, or otherwise enhanced to improve appearance, but this stone’s untreated status is a mark of integrity and rarity. Compared to similarly colored sapphires and tourmalines, which frequently undergo heating or other enhancements, an untreated Sri Lankan spinel with such a saturated greenish blue and dark intensity offers both aesthetic superiority and a transparency of treatment that serious buyers increasingly demand. The combination of natural origin, minimal inclusions, and no enhancement marks this as a collector-quality specimen.

Beyond intrinsic gemological qualities, this spinel’s dimensions and robustness make it a particularly smart choice for jewelry that will be worn daily or kept as a showcase piece. At 6.31 x 5.26 x 2.55 mm and 0.67 carat, it sits squarely in the ideal size range for center stones in delicate solitaire rings, refined halo settings, and classic pendant designs. Spinel rates an 8 on the Mohs hardness scale, offering strong resistance to abrasion and wear, while remaining easier to cut for precise, sparkle-enhancing faceting than harder stones. In practical terms this means you enjoy both attractive light performance and real-world durability, a combination that outperforms many similar-priced gemstones that may be softer or require additional treatments. Financially, spinel often delivers better value than a sapphire of comparable color and clarity, offering that rare mix of beauty, toughness, and an honest untreated condition that appeals to both modern buyers and traditional collectors.

Choosing this greenish blue oval spinel from The Natural Gemstone Company means selecting a gemstone where provenance, cutting excellence, and untreated clarity converge to create a superior centerpiece. Whether you are a jeweler seeking a unique focal stone to set in a bespoke commission, a collector adding a rare natural spinel to a curated cabinet, or a buyer looking for an elegant and reliable everyday gem, this stone offers a compelling alternative to more common market options. Its Ceylon origin gives it cachet among connoisseurs, its mixed brilliant cut and excellent polish deliver show-stopping brilliance, and its natural, very slightly included clarity ensures long-term appeal without the compromises of enhancement. We offer detailed images and measurements to support your decision, and our team is ready to advise on settings that will best showcase its depth and sparkle. This spinel is a statement of refined taste and smart value, and it will serve as a radiant centerpiece for any collection.
