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

One beautiful transparent 0.65 carat round greenish blue spinel, with measurements of 5.62 x 5.61 x 3.11 mm, presents a rich, bold face up color that conveys personal power and distinction. Cut as a faceted round with a mixed brilliant style, this gem balances scintillation and color saturation, producing flashes of deep teal and ocean blue across the crown facets. The stone has a dark color intensity that creates a dramatic and commanding presence when set as a center stone. With an excellent polish and no enhancement of any kind, this spinel is in a natural state that appeals to discriminating buyers who value authenticity and provenance. Sourced from Ceylon Sri Lanka, the gemstone carries the heritage of one of the world most respected gem localities, a region known for producing material with lively color and good crystal quality. The Natural Gemstone Company offers this spinel to collectors and connoisseurs who seek a stone that is both visually compelling and grounded in traceable origin.

From a gemological perspective this 0.65 carat spinel is graded as slightly included when evaluated at eye level, a common and acceptable clarity grade for natural spinels of this weight and tone. Slight inclusions are often internal mineral crystals or healed fissures that do not significantly interrupt light return, especially in a well cut mixed brilliant. The mixed brilliant cut used here optimizes pavilion geometry to return light and enhance perceived depth, while the crown facet arrangement emphasizes color rather than creating excessive brightness that could wash out the dark tone. Spinel is singly refractive and does not show strong pleochroism, which means the face up color you appreciate in the photos is representative under typical lighting. The species is durable with a Mohs hardness of 8, making it an excellent choice for everyday wear in rings, pendants, and fine jewelry that require both resilience and polish retention. Because this stone is untreated, its dark greenish blue color is stable and will not fade with normal exposure to light or household chemicals, a factor that increases its long term appeal and value.

For the educated buyer this spinel represents a compelling combination of rarity, stability, and aesthetic authority. The greenish blue hue is less commonly encountered in spinel than classic pinks and reds, which imparts a degree of rarity that collectors prize. Ceylon origin further enhances desirability, as Sri Lankan deposits have produced many historically important spinels and sapphires, and experienced lapidaries there are skilled at cutting material to maximize both brilliance and color. Slight inclusions should be viewed as evidence of natural origin, not as flaws to be eliminated by enhancement. If you are considering custom jewelry, this round mixed brilliant faceted spinel will sit beautifully in a single stone setting that allows light to animate the table and crown facets. For a refined, contemporary look choose a solitaire or a minimal halo to amplify presence without overwhelming the stone. For a secure setting that protects the girdle and pavilion, a bezel or well executed prong mount works well while preserving the gem visibility.

At The Natural Gemstone Company we document each gem with high resolution imaging and accurate measurements, and we are available to provide additional photographs and setting mock ups on request. We recommend routine care that includes removing jewelry for heavy manual work and cleaning with mild soap and warm water followed by a soft brush, avoiding ultrasonic cleaning if the mounting includes fragile elements. For buyers seeking formal verification we can arrange a laboratory report from an independent gemological lab to certify origin and confirm that the gem is unenhanced. This spinel is a statement piece, its rich, bold color functioning as both a wearable jewel and a symbol of distinction and inner authority, ideal for someone who values authenticity, fine craftsmanship, and the quiet confidence that a naturally beautiful gemstone conveys. Please contact The Natural Gemstone Company to discuss availability, to request additional imagery, or to explore custom mounting options.
