Welcome to the Mid Cornwall School of Jewellery


New Studio

We are updating this and will be launching a new website. Please check our contact page for our new address.


New Studio 

Here you will find a wide range of jewellery making training classes and courses of varying lengths, from single days and weekends through to classes lasting a couple of weeks. Whether you are a complete jewellery making beginner or a seasoned pro', we have a class for you. The jewellery school is based near St Austell in Cornwall, UK and all jewellery making classes run in our well equipped workshop.

Silver Metal Clay Diploma

This is also the home of the Diploma in Silver Metal Clay Proficiency, the first independent qualification for working with metal clay. It's the most thorough and comprehensive metal clay qualification in the world and is completely brand neutral, meaning you'll learn to work with both brands of silver metal clay.

Private Classes

We've added some case studies of students who had private jewellery making classes here at the school. This way of learning jewellery making is becoming more and more popular as people want to learn as much as possible in the shortest time. It also means you can tailor the classes to meet your specific jewellery making needs. Read more here...
