From our friends at Mountainside:

Classic and timeless, the Kay Necklace is an elegant and minimal textured thick chain that glides and dips along the collarbone with fluid movement and radiant shine. Made entirely from 18K gold fill or solid 18K gold, this piece stands out beautifully when layered or worn alone.

CARE: Most metals will naturally patina over time, however, there are measures you can take to prolong the life of your jewelry. We recommend removing all jewelry prior to showering, swimming, cleaning, or applying lotions or oils. If your jewelry begins to appear a dull or darkened, it can be gently polished with a soft jewelry cloth like Sunshine, with a non-abrasive jewelry cleaner, or a natural dish soap and a soft-bristled toothbrush. Storing in an air-tight container will prolong the life of your jewelry, and protect it from environmental tarnish.
