These light blue topaz earrings dazzle from sterling silver settings. The gems were mined in Brazil and given round brilliant cuts, weighing just over 1 carat total and measuring 5mm in width. They are set in 4-prong sterling silver basket settings on extra sturdy and extra long earring posts. The posts are 19mm long - only for people with extra thick earlobes. The screwbacks provide the most secure fit possible.
