For me these earrings represent winter, spring, and summer, as they appear on the boughs of a tree.
The top of the earrings is silver-white, like snow on the branches. The middle is a bright green, like young leaves in spring. And last is a rich, dark green, like the mature foliage of summer.
The earrings are made from enameled copper, with silver plated earwires, and measure 1.2" (30mm).
