Vivienne Sadler
Always too many temptations, but a joy to look through. Thank you for such good service. I have to be very strict with myself when I visit your website!
George Inglis
Great looking website, one of the best I've seen and used. Good search function, good range of products, good prices and great advice for jewellery makers of all abilities. All-in-all a great site and one I'll use again and again.
Julia Schofield
I’ve used Kernowcraft as a supplier for findings and pearls since beginning my business 8 years ago, because I know I can absolutely rely on the quality I get. The service is pretty impeccable too.
Jenny Kirkwood
Love the service you get and appreciate the range of products on offer. I just used the alligator tape for the first time and found myself asking - where have you been all my life?
Daniel Coe
The customer service I have received from you and the help has been second to none. If only all companies were so helpful and understanding that i am a complete newbie. The retail world would be a better place.
Frank Wilson
I have grown as a jewellery maker over the last year or so due to the encouragement the team have given me - they are all experienced jewellery makers or keen crafters. They have helped to guide me through my inventory, offered helpful tips and advice on all manner of silver working.
