    Machinist Bangle

    , ,
    The perfect minimal bangle, the Machinist Bangle looks stunning worn alone, or when layered with other bangles to add a touch of simplicity to any outfit. The Machinist Bangle, in gold, rose gold and silver, is the kind of simple, elegant bangle that stays in your collection for a lifetime. Please note - if selected, the inside of the bangle will be engraved.

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 unisex, stackable rings are versatile pieces for a variety of occasions.

The D-shaped ring comes in Sterling silver with a silver, 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.

Please note – if selected, engraving will be on the inside of the band.

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.
