The necklaces have pendants that are hand-carved in Ecuador by indigenous artisans using sliced tagua nut. There is a glazed ceramic bead above the pendant. These necklaces have nylon cords that can be tied at the back. The pendants are approximately 1" by 1.25" and 0.2" thick (2.5 by 3.25 cm and 0.5 cm thick) and weigh approximately 4 to 10 grams or 1/2-ounce or less. Each necklace varies slightly as these are handmade. The color of the bead used can vary as well. Tagua nuts are harvested in South America from the tagua palm, also known as ivory palm or ivory-nut palm. This fair trade product helps reduce the demand sustaining the illegal ivory trade, and these handmade collectibles are environmentally friendly and meant to be treasured. These necklaces are ideal gifts for a 14th wedding anniversary. The traditional material to give for the 14th anniversary is ivory. Tagua nut is a lovely substitute for ivory that honors the tradition while saving the elephants. There are no export controls for this item. Genus and species: Phytelephas aequatorialis. Wild.
