9ct Yellow Gold Blue John Peak District Millstone 70 Cufflinks. CL546. With proud links to the Peak District, C W Sellors have great pleasure in launching a new, limited-edition jewellery collection to celebrate 70 years of it being designated as the UK\'s first National Park and help raise important funds for its vital upkeep. The collection comprises a choice of two sizes of millstone pendant, adjustable bracelet and whale back cufflinks, with each piece a reflection of the natural beauty of the area with its world renowned and admired Derbyshire Blue John gemstone being at the heart of each design. Providing recognition to the important milestone achieved, each piece also features the number 70 subtly incorporated into the gold metalwork. Through any purchase from the collection, not only will you receive a jewellery piece that has been fully endorsed by the Peak District National Park Foundation and handcrafted within the area, but you will also be contributing to the Park\'s conservation work and helping prepare the Park\'s delicate habitats for a changing climate as C W Sellors are donating 10% of any sale to the Peak District National Park Foundation. From a single purchase from the Millstone 70 collection you could help fund two square metres of hay meadow restoration, or one square meter sphagnum moss - a climate change fighting superhero on the Peak District moors. All our Blue John jewellery is designed and crafted within our very own workshops in Ashbourne, Derbyshire where a team of skilled craftsmen transform natural pieces of Blue John into these stunning pieces of jewellery.  All articles are lovingly and securely dispatched with our elegant jewellery packaging. Dimensions: 18mm diameter.
