This stunning 0.88ct untreated ruby is truly a rare beauty! With great symmetry and a vivid and vibrant orangey red hue; this ruby will sparkle and glow as rubies do, under every light source day through night. . From the Umba River Valley of Tanzania we’ve recently acquired a small collection of rare untreated rubies with very unique properties that sets them apart from all others. Though they contain natural inclusions and growth characteristics, they have a remarkable level of transparency, and the slight orange undertone to their colors gives them an extra spark of intensity.
