A fabulous ring in brass alloy.  The centre piece holds a washer from the Aston Martin Valkyrie Hypercar race car gear box and also a ball bearing from the Mazda RT 24P race car gear box.  These have been set in an antique resin giving a tonal green to the setting.  A contemporary piece which is adjustable.  A great gift for any car or motorsport lover.  Comes in a black box, ready for giving.
