These purple threader earrings are so pretty. The purple/pink lab-created gemstones are lovely with gold, and the expert faceting makes these stones sparkle. The 8mm long teardrops are wrapped securely in gold wire and then suspended from dainty, gold-filled threaders. Also available in sterling silver. These earrings are about 3 1/2" (8.9cm) in length from one end to the other. Threader earrings may be worn at different lengths depending on your preference; these will hang about 2" from your ear, with the rest of the chain at the back. Included is a pair of plastic backings for added security. Your jewellery will be packaged in a small gift box. Gift wrapping is available upon request. What is Gold-Filled? Gold-filled is an economical alternative to solid gold. By law, it has 1/20th by weight layer of 14 karat gold permanently bonded over a core of base metal. It is tarnish-resistant, safe for sensitive skin and unlike gold plate, it will not wear off. It is a great way to enjoy affordable gold jewellery.
