Sterling Silver Whitby Jet Modern Framed Round Ring, R498. This circular Whitby Jet and sterling silver ring is hand polished so smoothly that this entire piece has a mirror shine. In Medieval times, Whitby Jet was used as small mirrors before man invented the silvering process which is used in making mirrors today. The Whitby Jet stone is sourced from the North East coast of Yorkshire and is set into the precious metal so that there is a flat surface and a flawless join between the materials.  All our Whitby Jet jewellery is designed and crafted within our very own workshops in Ashbourne, Derbyshire where a team of skilled craftsmen transform natural pieces of Whitby Jet into these stylish pieces of jewellery.
