1.68 Ct. Ruby from Burma (Myanmar)

This 1.68 carat round ruby from Burma Myanmar offered by The Natural Ruby Company is precisely faceted to balance color saturation and light return. The stone measures 7.37 x 7.25 x 3.89 mm, yielding a depth to diameter ratio of approximately 53 percent, and is cut in a mixed brilliant style with a brilliant facet crown and a modified pavilion geometry. This approach concentrates the vivid red hue into the face up view while preserving strong internal reflections. The clarity is graded as slightly included evaluated at eye level, which means small natural inclusions are present but do not compromise overall transparency. Excellent polish on all facet junctions enhances facet definition and minimizes surface diffusion, so table and star facets remain crisp and deliver clean facet flashes. The ruby has been heat treated, a stable enhancement commonly used to optimize tone and saturation, and the resulting vivid color intensity is representative of classic Burmese material.

Light performance is deliberate and predictable because of the mixed brilliant proportions and high polish. In bright daylight the stone displays an even, saturated red face up, with broad areas of pure chroma and secondary pinkish flashes in motion when the gem is tilted. Under warm incandescent lighting the red appears deeper and slightly more velvety, as the longer wavelengths reinforce the stone s strong saturation and the slightly included internal features create subtle pinpoint scintillation. Under modern cool white LED or daylight balanced artificial sources the mixed cut delivers lively white flashes from the crown and crisp red flashes from the pavilion, producing a dynamic contrast pattern that reads as both fiery and unified. Under focused spot lighting the polish and facet angles produce concentrated pinpoint brilliance and a stronger contrast between bright flashes and dark areas, which accentuates the ruby s depth of color. For settings that maximize brightness choose an open backed or prong mount to allow unimpeded light entry and maximize return, while a halo of smaller white stones will increase perceived brilliance and make the vivid color appear even more intense. This ruby s balanced cutting, precise measurements, and expert finishing make it a technical and aesthetic choice for connoisseurs seeking a compact, vividly colored Burmese gem.
