The details
Black round diamonds catch the light in this love knot necklace, a polished pendant in sterling silver that hangs from a fine box chain. The silver carries a rhodium finish, which gives it a bright white shine that sets off the dark stones. The knot is a pendant on a slim bail, so it hangs freely and moves a little as you do, while a spring ring clasp closes the chain and an extender adjusts where it sits. Wear it with a white button-down for work or a black dress for dinner. It is a thoughtful pick for someone marking an anniversary. Easy to love.
