This exceptional 5.35 carat Burma sapphire represents the absolute pinnacle of Sapphire quality, exhibiting the legendary "Royal Blue" saturation that defines top-grade gems. The color distribution demonstrates remarkable uniformity across the cushion's faceted surface, with no visible color zoning or secondary hue. The saturation reaches an optimal 85-90% intensity, creating the coveted "Roya Bluel" appearance that Burma sapphires are renowned for. Crystal clarity is loupe-clean with minute silk inclusions that actually enhance the stone's lustrous properties by creating internal light diffusion. The brilliance factor is exceptional, with each facet junction creating crisp light return and scintillation patterns typical of perfectly proportioned cushion cuts. Most significantly, the complete absence of heat treatment preserves the sapphire's natural crystal structure, resulting in superior hardness, enhanced pleochroism, and the distinctive fluorescent properties that separate unheated Burma stones from all other origins. And at over 5 carats, this is quite an exceptional gem.
This vintage 18K white gold setting features nearly flawless antique French square cut diamond side stones flanked by precision-cut baguettes, creating sophisticated geometric progression toward the round diamond halo that encircles the sapphire. The secure four-prong mounting showcases the cushion-cut sapphire while allowing maximum light penetration. At 6.76 grams, the substantial construction ensures lasting durability while maintaining refined proportions.
