Very nice quality mystic quartz. The photos don't show all the rainbow colors of pink, purple and green. Colors change in lighting and with movement. The french earwires are 14k solid gold or 14k gold filled or sterling silver - you choose. The gemstone size is 10x14mm, over 10 carats. Earrings hang 1.2 inches. The mannequin shows the relative size and how they will hang. Great everyday lightweight earrings. Shipping is Free!
