Money doesn't really grow on trees, or does it? In Asian culture, the money tree is a symbol of good luck that is said to attract wealth, abundance and prosperity. Our Money Tree Charm Earrings make a great gift for new grads and business owners alike (and for spendthrifts, too)! Charms measure 22mm x 18mm. Cast from lead-free pewter, plated and hand-painted in the USA. Earring hooks are sterling silver or gold plated French wire and include rubber backs.
