1.58 Ct. Ruby from Burma (Myanmar)

This listing presents a GRS certified vivid red Pigeons Blood ruby, a transparent 1.58 carat oval that measures 7.53 by 7.02 by 3.59 millimeters, cut in a mixed brilliant style, with a clarity grade of slightly included when evaluated at eye level, vivid color intensity, and an excellent polish. The stone carries no enhancement, and its documented origin is Burma, Myanmar. GRS certification confirms the gem has been examined by a respected independent laboratory, providing provenance and treatment verification that discerning buyers expect. The combination of a classic oval outline, precise proportions, and a mixed brilliant cut maximizes the gem's optical performance, making this example both visually striking and technically well executed for mounting in high end jewelry. The absence of enhancement is especially significant, because untreated Burmese rubies of vivid hue are rare in the current market, and command a premium among collectors and connoisseurs who prioritize natural state and origin authenticity.

From a grading perspective, this ruby demonstrates several attributes that educated buyers use to assess value. Color is the primary determinant for ruby pricing and this specimen exhibits vivid saturation with a balanced medium to medium deep tone, the color reading that most closely aligns with the historic Pigeons Blood ideal. Clarity noted as slightly included at eye level indicates the stone presents natural inclusions that are visible under close inspection but do not materially detract from transparency or light performance, a common characteristic in fine natural rubies from Burma. The mixed brilliant cut combines a faceted crown designed for brilliance with a pavilion optimized for light return, producing lively scintillation without sacrificing color depth. Excellent polish enhances facet crispness and surface reflection, contributing to a clean face up appearance. Optical properties typical of corundum, including a refractive index in the range expected for ruby and modest birefringence, yield an intense internal reflection and an adamantine to subadamantine luster, characteristics that experienced gem buyers will recognize as signs of quality.

When comparing reflective qualities to other gemstones in its category, this Burmese vivid red ruby stands apart for its combination of intense body color with lively internal reflection. Compared with heated or clarity enhanced rubies, an untreated Burmese ruby often shows a more saturated and velvety red, with reflections that are deep rather than washed out, because treatments that reduce inclusions or alter color can also change how light interacts with the crystal lattice. Against rubies from other origins such as Mozambique or Thailand, Burmese material is typically prized for a particular red hue and a softness to the light that many connoisseurs describe as glowing from within, whereas some other origins may display stronger pleochroism or a slightly more brownish undertone in certain stones. Compared with spinel and garnet, which can show excellent brilliance and sparkle, top quality Myanmar ruby retains superior color saturation at comparable sizes, and its refractive behavior yields a denser, more saturated reflection rather than the lighter flashes seen in spinel. Red tourmaline, such as rubellite, can approach ruby in color, but tourmaline generally has lower refractive index and different pleochroic behavior, so it tends to exhibit less intense face up color at similar saturation levels.

For an educated buyer seeking investment grade and museum quality characteristics, this GRS certified 1.58 carat Burmese ruby offers a compelling combination of provenance, natural state, and optical excellence. The Natural Ruby Company stands behind the description provided, including origin and treatment status, and can supply certification documentation upon request. This ruby is particularly appropriate for a collector who values natural Burmese material with vivid Pigeons Blood color and prefers a stone whose light performance communicates depth, life, and classic appeal.
