Catalogue Note: Sapphires from the Kashmir region rank among the most sought-after colored gemstones, prized for their distinctive saturated color and soft, velvety appearance. Production from the historic Kashmir deposits has always been extremely limited, with the original discoveries in the late 19th century quickly exhausted. Stones attributed to the broader Pakistan/Kashmir region remain scarce in the market, particularly in larger sizes. The present sapphire weighs 4.54 carats and is accompanied by a GIA Sapphire Origin Report identifying Pakistan/Kashmir geographic origin and noting no indications of heat treatment. Untreated sapphires of this size are uncommon, as many stones on the market have undergone thermal enhancement. The combination of documented origin, substantial size, and lack of treatment places this example within a highly desirable category for collectors of fine colored gemstones.
