The Machinist Ring, another of the studio’s signature pieces, is as interesting as it is unique; solid, yet delicate and detailed.
Like the Point Ring, another bestseller and a flagship piece, these chunky, unisex stackable rings are versatile pieces for a variety of occasions.
The D-shaped ring comes in silver with a gold or rose gold plated bar. Made to be mixed, matched and layered, alongside other Machinist Rings they align and unalign; playful and modern, and in keeping with the studio’s distinctive style.
The new Machinist collection was inspired by architecture and machines. Using geometric patterns and mechanical shapes, designer Matthew Calvin created a range of jewellery that combines unique shapes with high-polish finishes.
The designs echo the forms and lines of construction, architectural design and engines – drawing inspiration from details found within these places, and turning them into beautiful, minimalist handmade jewellery.
Our rings come in four sizes as standard, however more sizes are available - as well as extra special touches like inscriptions. Just get in touch and we'll create the perfect contemporary jewellery piece for you.
You can measure your own ring size easily at home, just cut a strip of paper and wrap it around your finger. If the paper rips, you're wrapping too tightly and would have ended up with ring too small.
Mark where the strip meets itself, and measure to the nearest millimetre using a ruler.
We recommend ordering a size up if you fall between two options.

The Octagon Bolt Ring's shape, as the name suggests, was inspired by mechanical forms; the angularity and symmetry of machines. The challenge was to create something which married this with the cleanliness and orderliness of Matthew Calvin's designs, something which was arguably perfected in this eye-catching piece.
The Point Ring, one of the studio’s first forays into 3D-printed design, proved so popular that designer Matthew Calvin decided to create a whole range of jewellery to complement it. However, the Point Ring remains the studio's bestselling piece, and the jeweller's personal favourite - designing himself a special edition 24-carat gold one for everyday wear.
