Duckweed Earrings
Duckweed (Lemna minor) is a freshwater aquatic plant with small leaves that floats on the surface of ponds. It is a source of food for water birds and shelter for frogs and fish. Due to its ability to take up heavy metals like lead, copper, and arsenic, it has been used to bioremediate contaminated ponds and lakes. It is also a useful substrate for bioethanol production due to its low cellulose content. Lemna has been an important model system in biology since the 1950s due to its rapid growth in culture and its ability as a floating plant to easily take up labeled compounds from liquid media.
The Duckweed earrings are asymmetric: one earring has 3 fronds and one has 4 fronds. The head of each earring is approximately 1 cm (0.4 inch) in diameter and the post diameter is 0.85 mm (0.3 inch).
The earrings are available in solid sterling silver or 14K gold plated brass, finished with nickel-free sterling silver or gold plated silver earring backs to match, and are ready for gift giving with a gift box, polishing cloth, and care instructions.
