Necklace layering is something of an art form and this gold plated disc looks wonderful mixed with shorter more delicate options. The disc itself measures 2.5cm in length (including the jump ring) by 1.75cm wide. Its also the most perfect little every day necklace if you just wanted to wear it on its own. The chain is solid sterling silver with 23.5k gold plate and is available in either the 50cm or 60cm length options. Remember the 50cm has a 45cm length option within the same chain, please see product photos for details.
