779W
Written by Olly Gerrish

An impressive 18ct gold and platinum ring that was made in France circa 1910-1920. It has been claw set with a cushion  cut  mid to deep blue sapphire that weighs over one and a half carats.  It is a Basaltic sapphire with no indications of heating. Around it are twelve claw set well matched old European cut diamonds that have a total estimated weight of 1.20 carats. The shank is unusual with incised and bobble motifs.

It sits low on the finger so it would make a perfect engagement ring.
