Precision faceted Blue Spinel from Tunduru, Tanzania — a color seldom seen in spinel and highly sought after by collectors. While spinel is more commonly known in reds, pinks, and purples, true blues are exceptionally rare and command attention for their vivid tone and brilliance. The Tunduru region, discovered in the 1990s, is famous for its rich alluvial deposits that produce a wide spectrum of unusual and fine gems. This area quickly gained international recognition for yielding stones of remarkable quality, and its production of rare colors like this makes Tunduru a key source in the modern gem trade.
