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. You can study jewellery making in metal clay here in Cornwall with us or study at home with the MCSJ Silver Metal Clay Home Study Diploma Course.

If you want the ultimate metal clay qualification, the Higher Metal Clay Diploma incorporates Art Clay or Rio Grande Certification classes and Copper Clay and Bronze Clay classes making this the highest metal clay qualification in the world. Click the Our Courses tab above and select the Metal Clay drop-down menu to find out more about this prestigious qualification.

Rio Rewards PMC® Certification Programme

We are very proud to announce that MCSJ are the official UK Partner of Rio Grande for the Rio Rewards PMC® Certification course. This course is only currently available through MCSJ in the UK and Europe. The curriculum complements the MCSJ Silver Metal Clay Diploma and offers students the opportunity to learn from world-class, respected instructors from the USA.

As a Rio Rewards PMC Certification holder, you receive discounted prices on PMC products, selected gems, tools and supplies bought directly from Rio Grande or PMC products bought from MCSJ. Best of all, there are no minimums or purchasing requirements—just purchase the PMC products you need! Successful completion of this certification also counts towards the Higher Metal Clay Diploma at MCSJ

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...
