1.15 Ct. Greyish Blue Spinel from Burma (Myanmar)

One beautiful transparent 1.15 carat cushion shape greyish blue spinel is presented by The Natural Gemstone Company, a gem of notable presence and refined proportions. The stone measures 6.58 x 5.79 x 4.08 mm, and its mixed brilliant cut has been executed to balance depth and table for optimal light return. At a clarity grade of very slightly included when evaluated at eye level, this spinel displays only minor inclusions that do not detract from its visual performance, allowing the intense color intensity to remain the defining characteristic. The polish is excellent, and the piece is in its natural state with no enhancement, making it an authentic example of fine spinel from Burma Myanmar, a locality historically associated with some of the most desirable material in the market.

Weight is one of the most important factors that governs both rarity and value in colored gemstones, and the 1.15 carat weight of this spinel is a meaningful threshold for discerning buyers. As spinels increase in carat weight, prices tend to rise at an accelerating rate because larger clean crystals suitable for fine cutting are less common. A 1.15 carat cushion has enough mass to present a strong face up presence on the finger, and the dimensions confirm a well balanced profile that reads larger than the weight might suggest to the untrained eye. For an educated buyer, this weight offers an attractive compromise between wearability and investment quality. It is substantial enough to anchor a classic solitaire ring or a refined pendant, while remaining within a size bracket that preserves the natural character and provenance of the stone. Furthermore, because spinel is a species that is typically found in smaller crystal sizes, an untreated example at this carat weight and with intense color from Burma Myanmar is comparatively rare, which contributes to its long term desirability among collectors and connoisseurs.

Beyond weight, the cutting style and proportions play a central role in how a gemstone communicates color and brilliance, and the mixed brilliant cut on this cushion spinel has been selected to enhance both fire and color saturation. The cut dispatches light effectively through the pavilion and returns scintillation across the table, which is especially important in a greyish blue stone where the interplay of blue and neutral overtones can shift under different lighting conditions. Spinel is singly refractive and does not exhibit strong pleochroism like some other blue gems, so the cutter s intention is clear in maximizing the single body color and ensuring an even distribution across the crown. The clarity grade of very slightly included at eye level indicates that any internal features are minor and do not interrupt the pathway of light, allowing the intense color to remain consistent. The excellent polish further enhances surface reflections and contributes to a lively face up appearance. From a gemological standpoint, the refractive properties and relative hardness of spinel, at about Mohs eight, make it both attractive and practical for everyday jewelry.

Provenance and treatment status are central considerations for collectors and informed buyers, and this spinel checks both boxes with a documented origin of Burma Myanmar and a confirmation of no enhancement. Burmese spinel has a storied reputation, and material from this region is often sought after for its classic tones and well formed crystals. An untreated stone of this quality is preferred by investors who value natural rarity and by jewelers who seek predictable behavior under various mounting and wear conditions. For those considering this gem as an investment grade piece or an heirloom, the combination of 1.15 carat weight, intense natural color, very slightly included clarity at eye level, excellent polish, and origin from Burma Myanmar creates a compelling package. The Natural Gemstone Company stands behind the description and can assist with independent certification options for buyers who require a laboratory report for insurance or provenance documentation. This spinel is ideally suited to a bezel set or four prong setting to showcase its cushion outline, and it will translate well into a design that emphasizes its rich greyish blue tone and substantial yet wearable carat weight.
