Beautiful high carat gold spinner fob.
Two snakes hold the spinner at it's axis either side, their tails coiling around their bodies to form the bail at the top.
The snakes are finely engraved with crosshatched bodies and sweet almost dolphin like faces.
The spinner is octagonal, set in the centre with and oval faceted amethyst.
On the front side of the stone the flat facet is engraved with a monogram. It's 2am now and I can't work it out, despite reversing the image! 
A.L or A.C or Q.L ?
The gold on the octagon is decorated with a pointillist style engraving which is very pretty also.
