This is a classic pair of modernism clips-on earrings created by Ivan & Co. back in the late 1970's. They were carefully crafted in the shape of cushions in solid yellow gold of 18 karats with parts in white gold for the settings of the diamonds, all finished with high polish. Diamonds: Mounted in inlaid settings, with 64 round brilliant cut diamonds, with a total weight of about 3.20 carats, white colorless F color, VS clarity. Turquoise: Mount in bezel settings, with 2 round cabochons cut of 15 mm carved from natural blue turquoise, with a weight of about 20 carats. Weight: 31.95 Grams (20.48 Dwt). Measurements: 30 mm by 30 mm (1.18 x 1.18 Inches). Hallmarks: They are both stamped with the maker's mark, the mark for the assay and warranty of the 18kt gold and signed as follows, "IVAN & CO .750 18 kt". Very good conditions. All our diamonds and colored gemstones are naturally earth-mined. Any synthetic (lab-grown) stones will be clearly indicated in the description. Upon Request, Auction House may provide an appraisal.
