Step inside the world's only commercially operating pearl farm, where Guaymas's legendary black pearls are cultivated in the pristine Sea of Cortez. A private, expert-led tour reveals the full lifecycle — from spat to lustrous gem — in a setting Jacques Cousteau once called 'the world's aquarium.'
What to expect
Your expert marine-biologist guide walks you through pearl cultivation tanks and open-water nurseries, explaining the painstaking grafting process behind every gem. You'll handle live oysters, examine pearls at every growth stage, and learn why the Sea of Cortez black pearl nearly vanished from the earth. The tour concludes in the boutique showroom, where you may purchase certified, sustainably farmed pearls directly from the source.
