This remarkable Montana sapphire celebrates the crystal’s natural growth pattern rather than concealing it. Parallel to the table is a striking series of concentric hexagonal zones — a rare phenomenon tied to the stone’s internal structure, likely a form of hexagonal silk or growth zoning. Rather than hiding these inclusions, master cutter Boyd Fox oriented the stone to highlight them, making the sapphire a true one-of-a-kind collector’s piece. Additional features include a few small bubble inclusions in the pavilion, but the overall presentation is dominated by the mesmerizing hexagonal design. A stone of this size and uniqueness would make a dramatic centerpiece for a pendant or display collection.
