A great choice for mechanics, engineers, tradespeople or anyone who appreciates tool inspired jewellery with a unique twist.
Please note: This ring is inspired by the design of an adjustable spanner. The ring itself is not adjustable and is available in fixed sizes. Please select your required size before ordering.

Fit Advice
Most rings sold on this website use a comfort-fit design, meaning the inside of the ring is slightly rounded. This allows the ring to slide over the knuckle more easily and feel more comfortable during daily wear.
If your knuckle is larger than the base of your finger, you may find that choosing half a size larger provides a more comfortable fit.
