The Verona Graduated Tennis Necklace runs a single unbroken line of round brilliant diamonds the whole way round, each stone held in its own slim four-prong head so light reaches it from every side. What sets it apart is the graduation - the stones swell gently from the nape towards the front, so the largest sit exactly at the centre where the eye falls, and the line tapers away so cleanly that you read it as one continuous ribbon rather than a row of separate stones. At seventeen inches it sits close at the base of the throat, high enough to wear on its own and slim enough to layer. Made to order, with the metal specified to your preference.
