From Metier by Tomfoolery, the Roma Adjustable Chain Necklace is the perfect layering chain. Made in Italy from 9kt yellow gold, it features alternating oval and round diamond filed links, which catch the light beautifully, and features a sliding clasp that is fully adjustable from choker length through to 18 inches. The chain looks great with any of Metier's plaques, if you want to add some color or texture.
