Posto Del Sol has a lovely line of zodiac-themed jewelry called Terra e Cielo (earth and sky). Each piece features one of the zodiac symbols in either gold or silver and they can be accented with either diamonds or semiprecious birthstones. The necklaces are elegant and very well made. The company uses only conflict-free diamonds and fair-trade gems, so you can feel as good about the elements in each piece as you can about they way you will look wearing it.

The Capricorn Pendant pictured is made of 18 karat yellow gold (also available in white gold) and is accented with a fair trade garnet and diamonds. Price: $625.
