Natural Pinkish Red Ruby - Unheated 0.71ct 5.2x4.5mm Cushion Cut

A natural cushion-cut ruby from Winza, Tanzania, weighing 0.71 carats and measuring 5.2x4.5mm. The cushion outline at 5.2x4.5mm gives a rounded square profile with excellent face coverage for the weight. The body color is a pinkish-red - the characteristic color of Winza material, which is noted for its natural warm pinkish tone that presents beautifully without any heat enhancement. Transparent with SI clarity, the stone shows clean and lively face-up.

Winza, in Tanzania's Mpwapwa district, entered commercial production around 2007 and quickly attracted gemological interest for producing high-quality ruby that is predominantly untreated and shows strong natural color. Winza rubies are sought after as a labeled, documented origin and are of specific interest to collectors and dealers who require confirmed provenance. At 0.71ct and 5.2x4.5mm, this is a practical size for a ring or pendant centerpiece.
