This adorable necklace makes a great personalized gift! The sandblasted sterling charm is stamped with an itty-bitty letter and comes with a lovely, 18" super-fine, sterling cable chain. The circle component of the charm is ~9mm.
See my other Tiny Initial Necklace options (two, three, or four charms on a chain) also listed in my shop. These are also available in 14k gold vermeil.
