0.55 Ct. Red Spinel from Burma (Myanmar)

The Natural Gemstone Company presents a finely calibrated 0.55 carat oval red spinel, measured at 5.80 by 4.22 by 3.02 millimeters, exhibiting a mixed brilliant cut with meticulous facet geometry and an exceptional polish. The cutter preserved weight while optimizing optical return, resulting in a depth ratio of approximately sixty point three percent which supports a strong face up presence without sacrificing pavilion performance. The mixed brilliant configuration combines a brilliant faceted crown with a complementary faceted pavilion structure, designed to concentrate and return light through the table while maintaining saturated color distribution across the face up view. Facet junctions are crisp and symmetrical, the girdle has been left within a sensible thickness range to balance durability and setting security, and the lapidary work emphasizes even facet size and alignment to minimize windowing and maximize scintillation. This level of craftsmanship yields consistent facet interaction under varied lighting, producing distinct flashes and a lively pattern characteristic of a well executed mixed brilliant oval.

Color and clarity are central to the character of this stone, the hue is a strong pure red with a slight secondary purplish undertone that is emblematic of high quality Burmese spinel, while the color saturation is assessed as vivid intensity which promotes deep, velvety color without appearing dull. The clarity is graded as slightly included at eye level, indicating the presence of small internal features that are visible under direct inspection but do not materially impede light travel or compromise brilliance when set. These inclusions are typical crystalline or healed growth features commonly seen in natural spinel from Burma, and they coexist with the excellent polish to deliver high transparency and lively internal reflections. Importantly, this spinel is unenhanced, showing natural color and structural integrity without heat treatment or other interventions, and provenance from Burma adds historical and gemological context that is often sought by collectors and connoisseurs. From an instrument based perspective, spinel is isotropic with a refractive index near 1.718, showing no birefringence, a refractive profile that contributes to clean, crisp facet reflections and a steady play of light rather than the doubled facet images seen in anisotropic minerals.

Durability and practical considerations are addressed by comparing hardness and resistance to abrasion, spinel rates eight on the Mohs scale which positions it as a highly durable gem for daily wear, significantly more scratch resistant than quartz at seven and garnet series stones which range from six and a half to seven and a half, while it is less hard than corundum varieties such as ruby and sapphire which are nine, and considerably softer than diamond which rates ten. The practical implication of hardness eight is that this spinel is well suited to engagement rings, pendants, and bracelets when set with appropriate protection, and classic settings such as four or six prong designs with well executed bezel or partial bezel options will afford additional safeguarding of the girdle and culet area. Given the slight inclusions, ultrasonic cleaning can be used cautiously after consultation, steam cleaning should be avoided if the inclusion morphology suggests internal cavities or healed fractures, and routine maintenance should include inspection of settings to ensure no undue stress is applied to facet junctions. For gem buyers seeking measurable gemological properties, this specimen offers a combination of precise cutting, vivid untreated color, and robust wearability, making it an attractive choice for both bespoke jewelry applications and serious gemstone collections, available through The Natural Gemstone Company with documentation of weight, dimensions, cut style, clarity grade, color intensity, treatment status, and country of origin.
