This lovely Opal drop necklace is Sterling Silver with an approx. 1 ct genuine Australian Opal, prong set in handmade settings.. The Opal is a natural, AAA top quality Opal and exhibits good fire. The setting is hand made by me and is a strong prong setting which keeps the Opals in securely. The Opal Necklace is approx. 1/2 long. (from the top of the bale to the bottom of the stone.) The chain is a durable cable chain and looks great with the Opal pendant. If you need a shorter or longer chain, please message me. Opal is the birthstone for October. Please note: The stone you will receive may not be exactly the same, as these are natural Opals, but will be of a comparable quality. I can gold plate or rhodium plate this piece. I can also make this piece in 14K or 18K white or yellow gold. It is a great size for everyone, including kids. Makes a wonderful gift! This piece will ship in a lovely jewelry box, ideal for gift giving. Please feel free to convo me with any questions.
