2.37 Ct. Blue Sapphire from Burma (Myanmar)

This 2.37 carat cushion shape blue sapphire presents precise, measured proportions and a level of finishing suitable for collectors and connoisseurs, dimensions 8.00 by 6.79 by 4.94 millimeters, depth approximately 66.8 percent. The gem is faceted in a mixed brilliant style, combining a brilliant-cut crown with complementary pavilion faceting to balance scintillation and face-up color. Color is described as medium light in intensity, a cool, clear blue with slight violet undertones that register consistently across viewing angles, and the stone shows an excellent polish that produces crisp facet junctions and lively light return. Clarity has been graded as slightly included when evaluated at eye level, with small natural internal features that are characteristic of untreated corundum, and importantly the sapphire has no enhancement, originating from Burma Myanmar, a source that historically yields specimens with exceptional character and material quality.

From a cutting and light performance standpoint the mixed brilliant design in this cushion emphasizes both brilliance and color presence. The brilliant facets on the crown create dynamic scintillation and maximize return through the table, while the pavilion facet architecture, arranged to support a deeper profile relative to width, helps concentrate color into the face-up view without sacrificing sparkle. The slightly deep depth percentage enhances saturation for a medium light intensity stone, concentrating the blue tone in the visible face without producing a notably dark or overly murky appearance. The cushion outline with gently rounded shoulders supports even facet geometry and minimizes windowing, while the finely executed facet arrays ensure that light is refracted and reflected in a controlled manner, producing a balanced mix of pinpoint and larger flashes across the surface as the gem is rotated under light.

Clarity considerations for this sapphire should be viewed in the context of its untreated origin and cutting. Slightly included at eye level indicates that the stone contains small natural inclusions, which in this specimen present as minor pinpoint crystals and fine silk like planar features that do not compromise structural integrity. These internal markers are typical of natural Burmese material and in many cases add to the gemological story, providing evidence of origin and authenticity, while leaving the stone attractive on the face-up view. The excellent polish and well-executed facet symmetry mitigate the visibility of these inclusions, as smooth facet planes and tight junctions reduce secondary light dispersion and maintain crisp brilliance. From a setting and design perspective the durability of corundum combined with a well-polished girdle and absence of significant feathering means this piece can be used confidently in rings or pendants with standard mounting practices, though orientation and bezel depth should be considered to keep visible inclusions in less conspicuous positions if desired.

As a centerpiece, this cushion blue sapphire makes a compelling focal point for both bespoke and classical designs, and The Natural Sapphire Company presents it as a premium untreated Burmese example that will anchor a collection. For maximum visual impact consider an open setting that allows light to enter the pavilion, such as a low-profile prong carriage or a partially open bezel that exposes the pavilion to light, which helps preserve the gem’s scintillation and cooler blue tones. Metal choice will influence perception, white metals will emphasize the stone’s cool blue, while warmer alloys can introduce contrast and make the hue appear richer. Given the gem’s roughly 8 by 6.8 millimeter footprint and 2.37 carat weight, common design applications include three stone rings where the central sapphire is flanked by tapered trapezoids or melee, solitaire rings with a halogen or LED accent lighting in the gallery for display, and pendant designs that suspend the cushion to maximize movement and light interaction. The combination of mixed brilliant cutting, excellent polish, natural Burmese origin and absence of heat or other enhancement make this sapphire an attractive choice for collectors seeking a piece with both technical precision and verifiable natural character, a true focal gem suitable for fine jewelry commissions and long term collection building.
