1.78 Ct. Red Spinel from Burma (Myanmar)

This Burmese red spinel offered by The Natural Gemstone Company is a transparent cushion shape weighing 1.78 carats, with dimensions 7.12 x 6.73 x 4.85 mm. The gem displays a vivid color intensity and an evaluated clarity of very very slightly included at eye level, with an excellent polish and a heat treated enhancement. The mixed brilliant cut and the maintained proportions produce a stable face up presentation, where color saturation and optical performance are both preserved and showcased.

The mixed brilliant cut is engineered to maximize light return while maintaining the deep red saturation characteristic of fine Burmese spinel. The crown facet arrangement disperses incoming light across multiple small facets, creating a controlled scintillation pattern, while the pavilion facets are angled to reflect light back through the crown rather than allowing it to escape through the pavilion. This interplay increases apparent brilliance and contributes to a lively, even flash distribution across the table and crown. The cushion outline and the measured depth work together to balance the gem placement of color, preventing a face up darkening that can occur in deeper stones, and minimizing windowing that reduces perceived color intensity.

The result is a gem that reads vivid and vibrant from multiple viewing angles, with bright scintillation and steady body color. The excellent polish enhances facet crispness and edge definition, which improves contrast and sharpness of light reflections. The very very slightly included clarity grade evaluated at eye level means the stone remains visually clean to the unaided eye while retaining natural internal character when examined under magnification. Origin information from Burma, and the disclosed heat treatment, provide context for the gem provenance and the enhancement applied to optimize color and clarity. This combination of weight, dimensions, cut style, and finish creates a balanced and technically refined red spinel well suited to quality jewelry settings, where the cutting design will continue to optimize light behavior and present a consistent, vivid appearance.
