There are 3 hallmarks on the ring - impossible to photograph clearly but can be seen with a jewellers loupe
First hallmark is of a bunny head and the number 3 which denotes Czech Republic 1957-1962
Next is the figure 900 which indicates purity of silver
Finally it has the letters RSC, this refers to the maker
Internal diameter of the ring is 19mm which is UK ring size R 1/2
Weight is 3g
Beautiful ring, my photographs do not do it justice!
Will post or can be collected from London SE9
I have had a big clearout on my jewellery so please do take a look at my other listings as well.
