18.17 Ct. Cabochon Ruby from Burma (Myanmar)

One translucent oval ruby, weighing 18.17 carats, is presented by The Natural Ruby Company, offering a clear specification of weight, shape, and dimensions for precise appraisal and design planning. The stone measures 15.89 x 12.72 x 8.55 mm, and is fashioned in a cabochon cut that emphasizes a smooth domed surface and an even outline. The overall shape is classic oval, with balanced length to width proportion that suits a variety of mounting styles. The cabochon profile provides a substantial presence on the finger or pendant, and the dimensions listed reflect the finished polished form of the gem. The origin is documented as Burma Myanmar, and the enhancement is heat treated, information that is included in the technical description to support provenance and treatment disclosure.

Color evaluation notes a pinkish red hue with an intense color intensity that is consistent across the viewable surfaces, contributing to strong visual appeal and presence. The term pinkish red conveys a slightly lighter undertone relative to the deepest pigeon blood designations, while maintaining saturated chroma that reads as vibrant in both direct and diffused lighting. The stone exhibits translucency, permitting light transmission through the body without full transparency, which enhances the depth of color and produces a velvety internal glow typical of cabochon rubies. The combination of intense saturation and translucent body color gives the ruby a lively appearance under standard viewing conditions.

Clarity is graded as included, evaluated at eye level, which indicates the presence of internal features that are visible without magnification. The inclusion pattern is typical for natural rubies from Myanmar, and in this specimen the features are distributed in a manner that does not dominate the overall appearance when viewed in typical jewelry settings. The excellent polish contributes to surface luster and optical smoothness, allowing the cabochon dome to display highlights and gentle reflections without polishing lines or surface abrasion. The polish quality, together with the cabochon geometry, supports symmetry and tactile quality important for secure and elegant mounting.

The documented heat treatment is a common and accepted enhancement used to improve color and clarity stability, and it has been disclosed to preserve full transparency in trade and appraisal contexts. Origin from Burma Myanmar is an important provenance note, as material from this region is historically significant and often sought for its natural color attributes. For professional use and valuation, a formal laboratory report is recommended, and The Natural Ruby Company can provide additional imagery, viewing orientations, and independent certification upon request. Care guidance includes routine cleaning with mild detergent and soft brush, and avoidance of prolonged exposure to harsh chemicals or extreme mechanical impact, consistent with handling recommendations for corundum group gemstones.
