This is a 2 inch Sea Heart (Entada gigas), a member of the family of nomadic sea beans that fall into the sea in the tropic regions and float around the world.
Dave hand carved this one and turned it into a unique magnetic needle and tool holder for your sewing table. He split this Sea Heart , removing the inside bean, and embedded a strong Neodymium Rare Earth Magnet in resin, then bonded the two sides back together. It is initialed and dated on the bottom.
