Reviews

From our customers

  • "The products are absolutely stunning. I have now brought 3 necklaces as gifts for friends. The service has been excellent with quick delivery and personal emails thanking me for my continued custom. The necklaces are even more beautiful and delicate than in the pictures."

  • "I ordered a necklace for my mum's 70th at short notice. They were fantastic, kept me up to date with my order and I received it much quicker than I expected. The necklace was beautifully made and presented well. I can't praise Decadorn's customer service and products enough. Fantastic."
