In my Mothers' jewellry was an old necklace made of metal squares. It mesures 18" across the top and has a Rau Fastener Co. snap to join it. The necklace has been heavily coated with gold. It is NOT a kerchief or scarf design. The little squares join by circles on the under side and count 3 squares down, then 5/6, 6/7 etc. until you reach the centre. At centre front it is 9/10. Very Egyptian styled appearance. Has anyone seen another like this and can anyone give me a date. I'm thinking 1920's but maybe 1930's. I have loved it since I was a small child and am now a senior.Mom just passed at 93.
