Gigantus 18.7mm Edison Pearl, Baroque

Size alone doesn't make a pearl exceptional, but at 18.5 mm, this Edison earns its name. The Gigantus is a modern marvel of freshwater aquaculture and single-graft selection, grown to a scale few producers ever attempt. Size: 18.7 mm Shape: Baroque Color: Dark lavender with a silver rainbow overtone Grade: AA, overall clean skin with some organic waves across the surface Immersion Time: 24 to 36 months post-graft, following 3-4 years of initial mussel growth. The Farming Reality: Edisons reach massive scale quickly because the mussel is huge and freshwater deposition rates are rapid. Second grafts are rarely attempted, since re-nucleating the visceral mass carries high mortality and loose-sac rejection risk, making this a one-shot harvest. An exceptional, large-format pearl for a collector who wants presence as much as provenance.
