My favorite earrings are the left pictured "gypsy" hoop earrings. They are a perfect in 1" diameter -- large enough to make an impression, but not so overly huge that they become de facto unprofessional. $38; find them here. For something slightly longer, try the turquoise chandelier earrings. $48; here.
The earrings pair fantastically with the "illusion" beaded necklace pictured right. I really like the interspersing of the colored glass beads with the matching turquoise beads. The necklace is 36" long -- great for wrapping into a double-strand. $58; find it here. For something all turquoise like the earrings, I also like the chunky turquoise necklace. $198 (it contains a lot of turquoise and is a long 34.5"); here.
