Without jewelry, humans would be forced to add shine to outfits with burned out strings of Christmas lights and stuffed anglerfish. Add bejeweled light to dull wardrobes with today's Groupon: for $20, you get $40 worth of jewelry online from Athena Accessories.

The Bures sisters in Texas and the Qiao sisters in China form the intercontinental brain trust behind Athena Accessories, creating handmade jewelry from freshwater pearls and other stones. Most earrings cost $16, such as the classy agate and shell lobe-hangers and the natural jade globes, with a translucent green surface which also reveals the future to fortunetelling Hulks. Necklaces accentuate collars with colorful strands, including the versatile egg pearl necklace with a crystal-crusted clasp ($45). Polychromatic wrist bling, such as the freshwater rice and coin pearl bracelet ($32) and the flower-adorned queen pearl bracelet ($22.50), makes elevator doors ten times more likely to stay open for outstretched arms. The shop also stocks a panoply of pieces for brides as well as jewelry sets for match-happy patrons. Chinese artisans hand-finish almost every item, drilling holes into stones, knotting necklaces via needle and thread, and punching giant oysters to knock out their pearly teeth.
