0.83 Ct. Ruby from Burma (Myanmar)

This transparent 0.83 carat Burmese ruby from The Natural Ruby Company is fashioned in a precision emerald cut, measuring 5.94 by 4.28 by 3.22 millimeters, with an approximate depth of 63 percent, a cutting proportion that balances face up presence with color saturation. The emerald cut employs broad step facets on the crown and pavilion, a generous table and neatly truncated corners, producing large, flat facet planes that emphasize the stone's vivid color intensity and internal structure. Clarity is graded slightly included when evaluated at eye level, meaning characteristic natural inclusions are present but do not dominate the stone face up, and the excellent polish delivers sharp facet junctions and clean reflections, maximizing light return. Enhancement is standard heat treatment, applied to stabilize and intensify tone and saturation, and the ruby originates from Burma Myanmar, a source noted for strong natural color and often pronounced fluorescence that can further enrich the face up appearance.

Under different lighting conditions this emerald cut ruby reveals distinct optical behavior that will interest connoisseurs. In bright daylight and neutral LED, the broad table and step facets present an even, saturated red with subtle zonal variation, the vivid color intensity appearing consistent across the crown, and the step facets create broad flashes rather than fine scintillation, lending a classical, gemmy look. Under incandescent and candlelight the stone typically appears warmer and more luminous, with the red deepening and any natural fluorescence common to Burmese material often enhancing the vividness, creating a rich, velvety red that reads visually deeper than under neutral light. Under mixed or fluorescent lighting the stone can show slightly brighter pinkish red flashes along facet edges due to pleochroic effects, while the slightly included clarity may produce localized color contrasts that add character rather than detract. For mounting, an open prong or minimal bezel setting will preserve light access to maintain lively color, while a lower profile can reduce windowing and emphasize depth of tone. This specimen is ideal for buyers seeking a technically well executed step cut ruby that showcases classic Burmese color with precision cutting and superior polish.
