This is a beautiful and substantial little piece of jewelry. It's a solid 14k yellow gold clam shell pendant, meaning it's not hollow – it has a nice weight to it (about 0.9 grams). The design is lovely, with a textured finish and a high polish that makes it catch the light. It measures approximately 16mm long by 12mm wide, with a 5mm tall bail (the loop the chain goes through). Important note: This listing is for the PENDANT ONLY – it does NOT include a chain. You'll need to add it to your own favorite chain. It's hypoallergenic and nickel-free. The clam shell is often seen as a symbol of good luck, protection, or travel. It comes ready to give in a nice gift box. It's perfect for layering with other necklaces or wearing solo as a delicate statement. A timeless piece from Jewelryweb, a seller with decades of experience. A wonderful gift for a birthday, anniversary, or just because.
