GOLD TONE VINTAGE DOUBLE SNAKE HEAD NECKLACE WITH GREEN STONES

Here's a double headed gold tone vintage snake head necklace.  It has oval green glass stone in the heads.  It is marked 'Foreign' and 'Rolled Gold'.  It is in such good condition I though at first it was more modern - but on closer inspection I would think it was 1930-1950's.  The marks would also indicate this.  Full details on my web site - www.gillianhorsup.com - reference 2754 C7/6
