7.54 Ct. Blue Star Sapphire from Burma (Myanmar)

This 7.54 carat oval blue star sapphire is presented as a cabochon, with dimensions 11.22 x 8.49 x 7.10 mm, and originates from Burma Myanmar, untreated and unenhanced. The material exhibits translucent body color with intense color intensity, a vivid medium to deep blue that is evenly distributed across the table and pavilion regions. Clarity is graded as very slightly included at eye level, the inclusions manifest primarily as oriented rutile silk and minor pinpoint features that do not materially disrupt the asterism or the structural integrity of the stone. Optical transmission remains strong given the translucency, allowing the six ray asterism to read sharply, and the lack of heat or other enhancements preserves the natural pleochroic balance and inherent color zoning characteristic of Burmese material.

The cutting and finishing demonstrate considered lapidary technique, the oval outline and 7.10 mm dome height provide an optimal profile for asterism, with the cabochon axis aligned to the crystallographic c axis to concentrate the parallel rutile needles that form the star. The six ray star is well centered and displays clean, relatively narrow rays that converge on a distinct focal point under a single overhead point light source, evidence of consistent silk orientation and precise preform planning. Proportions are balanced to maximize star contrast against the saturated blue body color, and the excellent polish enhances light return and surface luster while minimizing extraneous reflections that can diffuse the star image. The combination of intense body color, controlled translucency, and meticulous cabbing produces a star that is mobile yet defined, appearing crisp at typical viewing distances and resilient to routine wear. The Natural Sapphire Company stands behind the provenance and untreated status of this piece, and can provide further technical documentation on the cut geometry and inclusion characteristics upon request.
