What happens in this class?

Hosted by award winning jewellers Milena Kovanovic (Crucible London) & Ros Millar with The Ringsmiths team. In this direct casting method, molten metal directly fills a design carved/imprinted into the surface of a cuttlebone. Producing a finished three-dimensional cast object - in this case a signet ring. This technique is one of the earliest known casting processes used by man for thousands of years.

Over the course of this 4 hour workshop we will teach you everything you need to know about how to prepare and cast your very own silver signet ring. You will have plenty of opportunity to…

Things to remember

Each student will be provided with an apron, though we ask you to please wear suitable non- loose clothing (as you would for any other semi-messy art form). For health and safety we also recommend close toed shoes.

Can I make a solid gold signet ring?
Yes, the most cost effective way to cast your ring in solid gold is to create it in silver and then on the day of the class we would weigh your silver ring and quote you for it in solid gold by creating a mould and lost wax casting it. We have done some 9ct signets recently and were coming out around £300

I loved my few hours at The Ringsmiths! I made two signet rings from the casts and am so thrilled with them. I'll be back to do another course as soon as I can. Thank you for organising a great day.

Such a fun class, enjoyed every minute
Leo - 5 December 2022
Really great experience. The tutors were welcoming, supportive and friendly. I'd recommend the Signet Ring course, it was a little bit nerve-wracking to make both the mould and do the casting, but I'm really happy with the end result.
Naveen Mahil - 17 November 2022
Super fun and informative class, and loved that I was able to walk away with a new piece of sentimental jewellery! Would recommend as a gift idea (and already have to lots of my friends!)

James York - 19 February 2022
I went with my partner as a birthday present and I have to say it was such a good gift! It's original, thoughtful, hands on and you walk away with a very personal momentum. I came into work the next day and people absolutely lose thier minds. The rings can come up so unique. The faciliators were so nice and lovely. I instantly felt comfortable. I will 100% recommend this for anyone who might be struggling to get a personalised gift.

Martin - 23 June 2021
I can't recommend this class enough! Excellent tuition, taking you through every step clearly and methodically, making sure everyone understood everything. Rings were sized if needed on the day prior to spending time to achieve ones desired finish. Add ones of plating and gems were very reasonable and was not pressured in any way. We can't wait to receive our finished rings complete with gems.
Ellie - 27 April 2021
Would 100% recommend the make and cast a signet ring class to anyone! Really enjoyed learning about the background of the ring casting and getting the chance to cast the ring ourselves. Such a cute workshop and the addition of a puppy was a bonus!
Ahmed - 8 December 2020
Ros and Milena were very helpful in explaining everything and were very patient during the process. I have recommended the signet ring making course to many friends. Looking forward to receiving the ring back from the engraver and seeing the blue sapphire set.

Milena and Ros were such great teachers! Super personable and friendly. The workshop was great and is super comfortable (especially in covid times!) I went with my boyfriend for his birthday and had a really good time. Highly recommend for anyone!
Lucie Silveira - 8 February 2020
Loved this class, Ros and Milena were perfect hosts as well as great teachers. I learnt how to prep a cuttle bone to create a mould for my ring, and then how to pour the molten silver, which was both scary and exciting! And then to polish and clean up the ring. Really interesting class and I love my signet ring that has a story as unique as it is. Thanks so much Ringsmiths! xxx
Shivani - 22 January 2020
I thoroughly enjoyed myself taking part in this class. The pace of the class was perfect, incorporating useful information about the source of cuttle fish, the science behind casting and techniques which enhances the making of such product. Milena and Ros were so patient, supportive and friendly. Snacks and beverages were also provided. All in all, an enjoyable day which is well organised. The best part is walking away with a finished ring!
Saul - 22 January 2020
I cannot recommend this workshop enough, the teachers were great and the rings we made look amazing. I’ll be coming back to do another workshop for sure.
