This adorable necklace makes a great personalized gift! The vermeil charms are stamped with an itty-bitty letter and come with a lovely, 18" super-fine, 14k goldfill cable chain. The circle component of the charm is ~9mm (the model photo is of a single charm). Please include your letter choices during checkout.See my other Tiny Initial Necklace options (one, three, or four charms on a chain) also listed in my shop. These are also available in sterling silver.
