1.16 Ct. Blue Spinel from Ceylon (Sri Lanka)

This exceptional 1.16 carat round blue spinel is an elegant and rare offering for the discerning collector, presented by The Natural Gemstone Company. The stone measures 6.28 x 6.20 x 4.02 mm, and it is faceted with a modified brilliant cut that has been executed to balance scintillation and depth. The gem is transparent with medium color intensity, and it displays a clear, consistent blue tone that reads neither too dark nor too pale under standard daylight. The clarity has been graded as slightly included when evaluated at eye level, and the polish has been assessed as excellent, giving the facets crisp edges and lively reflection. There has been no enhancement performed on this spinel, which preserves its natural character and provenance from Ceylon Sri Lanka, a region renowned for producing high quality spinel specimens.

From a lapidary perspective the modified brilliant cut used for this round spinel is particularly well suited to this size and material, because it maximizes return of light while moderating depth to retain face up presence. The excellent polish contributes directly to the gem’s visible brilliance, with facet junctions that channel light in coherent flashes rather than scattering it. The proportioning at approximately 4.02 mm depth produces a balanced table and crown relationship, yielding a pleasing mix of sparkle and depth. Slight inclusions are present, consistent with the slightly included clarity grade, however these internal features do not significantly impede the stone’s transparency or its ability to flash light. For collectors who assess gems visually rather than through magnification, this means the gem reads as attractive and lively in hand, while still offering natural internal characteristics that attest to its authenticity.

Color and origin are central to the value proposition of this spinel. Ceylon Sri Lanka has a long established reputation for producing blue spinels with stable, attractive hues and clean tone balance, and this gem exemplifies those qualities with its medium intensity blue. In gemological terms medium intensity provides the best compromise between saturation and lightness for wearable stones, as it ensures the color remains apparent under a range of lighting conditions without appearing overly dark on the finger. Spinel itself is a durable gem species, with a Mohs hardness of eight, making it suitable for everyday jewelry such as rings, pendants, and secure settings. Because this particular stone is natural and has not been heat treated or otherwise enhanced, it carries an added premium for collectors and investors who prioritize origin and treatment disclosure. Natural Ceylon spinels of clean appearance and no enhancement are highly regarded in the secondary market, and their provenance contributes positively to long term desirability.

For an educated buyer seeking a meaningful addition to a high end gemstone collection, this 1.16 carat round blue spinel represents a strong combination of aesthetics, integrity, and wearability. Its weight and proportions make it versatile for custom settings, and its natural origin and absence of enhancement align with collector preferences for traceable, untreated material. From an investment and curatorial perspective, the presence of slight inclusions provides a fingerprint of natural formation that supports identification and long term value retention, while the excellent polish and skilled cutting ensure that the gem performs beautifully when set. The Natural Gemstone Company stands behind the accuracy of the description and can assist with optional documentation, certificate recommendations, and bespoke setting consultations, to help integrate this spinel seamlessly into a curated collection or a signature piece of jewelry. For collectors who prioritize provenance, durability, and natural beauty, this Ceylon blue spinel is an exemplary choice.
