Surrounding an orange/ruby-lined star centre cane are 2 rings of alternating canes. The first with green/white, yellow/white complex canes; the second with blue/white and orange/ruby-star canes (a repeat of the centre cane). Sections of white latticinio - enriched with copper aventurine - placed lengthwise around the perimeter, are separated by maroon/ blue cogs. Set over a translucent, mottled blue ground.
The fire-polished base is slightly concave with a rough pontil mark.
(Greyish tint to the glass -probably 1940/50s Moncrieff period).
