Welcome to ASD Jewellers. Since 1977, our family run business has embraced the age-old traditions of handcrafting jewellery.

Our signature collection features the blue john stone, known for its distinctive bands of purple-blue or yellowish colour.

Since the 19th century, this unique semi-precious mineral has been mined in the caverns surrounding Castleton, in the heart of the Peak District, where our workshop is based and the only known depository of blue john in the world.
