0.49 Ct. Pinkish Red Ruby from Burma (Myanmar)

This example of Burmese corundum from The Natural Ruby Company is a transparent, cushion shape ruby weighing 0.49 carat, with precise dimensions of 4.77 x 4.06 x 2.69 millimeters. The gem has been cut to a mixed brilliant style, combining a faceted brilliant crown with a mechanically optimized pavilion, to maximize both color saturation and light return. Clarity is graded very slightly included, evaluated at eye level, indicating minor internal features that do not materially interrupt the visual field, and polish is excellent across all facets. Color reads as pinkish red with vivid intensity, a balance of primary red hue and a secondary pink modifier that gives the stone lively chroma in both daylight and incandescent lighting. Enhancement is by controlled heat treatment, a stable and widely accepted process for improving color and clarity in rubies, and the stated origin is Burma, Myanmar, a source noted for historically high quality material and strong color character.

From a faceting and optical standpoint, the mixed brilliant architecture on this cushion profile has been executed to maintain a slightly deeper overall profile, with a depth ratio of approximately 61 percent relative to the mean diameter, which supports saturation without creating an overly dark window. The crown presents a sequence of kite and star facets that refract and break incoming light to generate scintillation, while the pavilion facets are arranged to redirect light back through the color body, enhancing perceived vividness. The combination of facet junction integrity and excellent polish reduces light leakage and optimizes return, producing an even face up appearance across the table and bezel facets. The subtle asymmetry inherent to natural rough has been managed with careful pavilion planning to preserve weight while achieving balanced facet angles, a technical compromise that benefits both proportion and brilliance for a small sized ruby.

Color quality in this specimen is the standout technical attribute, the vivid intensity arising from an optimal interplay of hue, tone, and saturation. The primary hue is a pure red leaning toward pink, the tone occupies the medium to medium dark range which is ideal for small stones where over darkening can reduce apparent size, and saturation remains strong, conveying the richness expected of Burmese material. Chromatic concentration is evenly distributed without dominant zoning, and the stone exhibits lively color when tilted through different lighting directions due to natural pleochroic tendencies in corundum, showing slightly more pinkish red versus deep red facets depending on angle. Heat treatment has been applied to stabilize inclusions and enhance the chroma, producing a durable color that resists fading under normal wear conditions. The excellent polish enhances surface luster and allows the vivid internal color to translate into a velvety, lively face up presence when set.

For long term enjoyment and preservation of its technical attributes, this ruby benefits from standard care appropriate to corundum hardness and toughness, including periodic professional cleaning to maintain facet brilliance and secure setting to prevent knocks that could blemish polished surfaces. The combination of transparent body, mixed brilliant cutting, very slightly included clarity at eye level, and stable heat enhancement means the natural beauty of this stone will continue to captivate for decades, retaining strong color saturation and dynamic light performance in everyday jewelry use. At The Natural Ruby Company we source and cut material with attention to optical optimization and responsible origin documentation, and this 0.49 carat Burmese cushion ruby is ideally suited for an elevated ring, pendant, or bespoke design where technical quality and enduring visual appeal are paramount.
