A large, earthy untreated yellow sapphire oval from Tanzania, presenting a dark olive-brown body with brownish-khaki undertones and warm golden flashes catching at the facet edges. The color is deeply terrestrial and organic, sitting at the intersection of earthy yellow and smoky brown in a tone that feels raw and unfiltered. Dense natural inclusions limit the transparency and contribute to the stone's heavily natural, unpolished character, giving it a strongly individual quality that sets it apart from conventionally faceted gems.

Completely untreated and unheated, from Tanzania, one of Africa's most important sapphire-producing countries. The untreated status is verified and adds significant natural integrity to this stone, which preserves the full, unaltered color and inclusion landscape as it formed in the earth. This is a stone for collectors and designers who value raw, natural character over conventional clarity and saturation. Its large 8.5x6.7mm oval format gives it strong visual presence, and the earthy olive-brown tone pairs well with warm yellow gold, oxidized silver, and other organic, nature-inspired materials.
