I've had multiple online shopping experiences with ASD Jewellers. Their communication is first class. I'm always kept updated on the progress of my order. Orders arrive quickly and are very well presented. I can always rely on this shop if I'm in need of a present sending quickly. The items of jewellery are well designed and made. My pieces all showcase Blue John very well. I love how unique this jewellery is. I hope to visit the shop in the future to appreciate their full range of jewellery.

I can’t thank Anthony and the team enough. I bought a blue john necklace from a local jewellers for my sisters 40th, and had spent a long time trying to find earrings to go with it. I loved a design with ASD and in the picture the stones looked a good match. I didn’t realise that the pictures were not the actual pair of earrings but a image of the design (totally Naive). The earrings arrived and unfortunately the stone looked completely different to the necklace, though gorgeous quality. I contacted ASD, along with a pic of the necklace, to see if they would be able to check if they had anything

By far the most individual and reasonably priced Blue John jewellery in Castleton. Absolutely lovely staff. Even though I was the last customer of the day they took the time to make me feel special and appreciated that my purchase was something that would be significant to me for the rest of my life. Lovely people.
