1.15 Ct. Greyish Blue Spinel from Burma (Myanmar)

This listing describes one transparent 1.15 carat cushion shape greyish blue spinel, offered by The Natural Gemstone Company, with dimensions of 6.97 by 5.40 by 3.92 millimeters. The stone is cut in a mixed brilliant style, combining step and brilliant facets to balance light return and face up color, and it has an excellent polish. Color is a medium intensity greyish blue, displaying even saturation across the table and crown, and clarity is graded as slightly included when evaluated at eye level, with minor internal characteristics that do not disrupt overall transparency. There is no enhancement of any kind, and the origin is Burma, known for producing spinels with stable, natural color. The precise carat weight of 1.15 carat places this stone in a size category that is both practical for a variety of jewelry applications and significant in terms of rarity for fine natural spinel from this locality.

The weight of 1.15 carat is an important indicator of both visual presence and market quality for spinel, the combination of weight and proportion influences perceived size and light performance. With a length of 6.97 millimeters and a width of 5.40 millimeters, the gem presents a slightly rectangular cushion outline that reads as substantial on the finger while remaining comfortable for everyday wear. The depth of 3.92 millimeters corresponds to an approximate depth ratio of sixty three percent based on the average of length and width, a proportion that supports balanced scintillation and retention of color without appearing overly deep or shallow. The mixed brilliant cutting scheme enhances fire and sparkle by incorporating a pavilion arrangement designed to return light through the crown, while the excellent polish ensures crisp facet junctions and minimal surface disruption to light flow. Slight inclusions visible at eye level are typical for natural spinel at this size, and they are contained and positioned in a way that does not materially impair brilliance or durability.

Origin and natural state contribute to the intrinsic and collectible quality of this spinel, Burmese spinel being historically prized for its stable color and crystalline integrity. The lack of enhancement is a defining attribute for buyers seeking untreated gemstones, and in combination with the one point one five carat weight, the stone represents a premium offering that balances rarity and wearability. On the practical side, spinel is a durable gem with good hardness, appropriate for ring centers, pendants, or bespoke settings where color and clarity are showcased, and the cushion shape with mixed brilliant facets adapts well to both prong and bezel mounts. For professional gemological enquiries, independent testing, or additional imagery and measurements, The Natural Gemstone Company can provide documentation and support to confirm the described parameters, ensuring the specimen meets exacting standards for weight, cut, polish, color intensity, clarity, provenance, and treatment status.
