A massive 134.74 gram Natural blue alluvial topaz from Colombia. Waterworn (alluvial) piece with strong blue saturation
Most blue topaz on the market is created by treatment, which is why a naturally blue stone of this size stands out. The last photo shows the piece is not perfectly clean, but the combination of genuine natural color, saturation, and scale is the point here—this is a collector-grade alluvial topaz that is rarely seen in the trade.
