Natural Yellow Sapphire 0.98ct Untreated Fluorescent Oval Cut

A distinctively characterful 0.98ct oval sapphire from Tanga, Tanzania, presenting a pale brownish-champagne body with a warm, taupe-like tone and a subtly smoky quality. The color is muted and earthy rather than vivid, carrying a nuanced depth that sits at the intersection of pale yellow, beige, and champagne. The stone is fairly transparent, with feathering and fine natural needle inclusions running through the interior. Its most remarkable feature is a strong orange-red fluorescence under 365nm UV illumination, which transforms the appearance of the stone dramatically and adds a rare optical dimension.

Completely untreated, from the Tanga region of Tanzania, an important African sapphire origin producing naturally colored stones with unusual optical properties. The combination of natural color preservation, untreated status, and vivid fluorescence makes this a compelling collector's stone. Buyers who value natural, unmodified gemstones with distinctive character will find this stone particularly rewarding, and the fluorescence makes it an especially interesting piece for a pendant or ring setting where different lighting conditions can reveal the stone's hidden orange intensity.
