These antique style earrings are sterling silver with diamonds and blue paste stones that appear to be imitation sapphires. The diamonds look invisible in the pictures, but they are there, and do test positive (tried 2 different testers). These earrings are encrusted with rose-cut diamonds. These earrings are in a Georgian Style..They are revival earrings. The earrings are done in an attractive antique style. They are marked "925 A4 C0032." I have been unable to identify this mark. The earrings measure 1 5/8 inches long and are in very good condition. They are for pierced ears. Gorgeous!!
