FAQS

Do I need jewellery-making experience?
No, most of our customers are first timers. You role is to simple design and carve the form in wax – we handle the technical casting.

What if I make a mistake in the wax?
That's completely normal. Wax is forgiving – you can reshape it, smooth it, melt small sections back together or start again. If unsure you can add some extra wax to your basket.

What if I am unsure about size or style?
You size it yourself. When it comes to the width of the rings we say 3mm is for a delicate, fine jewellery stacking band, 5mm for a small signet, 8mm for a chunky band or signet.

Is this suitable as a gift?

Yes the kits are designed to be meaningful, hands-on gifts – especially for people who enjoy making something personal. You don't need to know their ring size to get started as they size it themselves.
