A lovely pair of Blue John drop earrings in hallmarked 925 sterling silver on hook wires. Made in our Sheffield workshop, these earrings feature 7mm Blue John stones with solid silver backs.
Our stones are 100% natural and therefore may vary slightly in colour and pattern from the photos. However we guarantee they are of the highest quality and handpicked specifically for each design.
Now a little bit about the stone…
Blue John (also known as Derbyshire Spar) is a semi-precious mineral, a form of fluorite with bands of a purple-blue or yellowish colour. In the UK it is found only at Blue John Cavern and Treak Cliff Cavern at Castleton in Derbyshire. During the 19th century, it was mined for its ornamental value, and mining continues on a small scale.
