Emerald and diamond ring, late 20th century. This three-stone emerald and diamond ring is a classic in many senses. Firstly, it's a classic design - a three stone ring, which sits beautifully on the finger alongside a wedding band. Secondly, at its centre is a Colombian emerald - traditionally the source of the world's best emeralds, faceted in the signature emerald cut, the corners of which are protected by yellow gold claws, adding a touch of contrast against the green. Finally, its shoulder stones are another perfect choice - a pair of beautifully-matched brilliant-cut diamonds, which sparkle beautifully alongside the emerald without distracting from it. A beautiful example of a truly timeless design, built around excellent stones.
