From Castle to Coast

We are a family run jewellery & antiques business based in the historic coastal town of Kinsale, Ireland. However, our story began at a castle overlooking the Blackwater river in north County Cork.

From the Workshop Bench

If you know exactly what you want but can't find it in our collections, we can make it for you.

Why not design your own ring with LOK?

Our staff are GIA trained and our diamond setters are Boodles and Graff trained. Together they are happy to help you with design, to create the finest quality bespoke pieces to fulfil your dreams. We also have a selection of fine hand made platinum mounts for you to choose from. All of these settings are also available in white and yellow gold.

We can make any design so just give us a call if you are looking for something in particular. We also deal in speciality side stones like kites, shields and even horseheads!
