Six vintage aluminium napkin rings, serviette rings. Conrah Cristillium? Anodised multi-coloured metal, diamond cut. Modernist 1970s retro

A set of six of unusual and amazing striking Cristillium (aluminium based) napkin rings, most likely by Conrah Metal Products, Wales. Circa 1970s vintage.

They have an anodised coating which been machine-cut through in a diamond pattern and at an angle top and bottom, to reveal the reflective silver coloured metal below. They're round internally and ridged externally, with 6 rounded dips. They catch the light in a really striking reflective way. Striking yet simple Modernist British design. The rings are shiny metallic peach, blue, red, gold, moss green and black.

Internally 4.1cm, externally 4.9cm diameter. They are in great condition for the age with just a few small signs of use.
