Victorian Rolled Gold Mini Locket or Watch FOB

This is a wonderful little gold locket with black agate or onyx on one side and white agate on the other side. Inside there is a layer of boodstone underneath the white agate. The loop at the top is broken and will be replaced, and inside there is plastic on the bloodstone side but nothing on the black side - originally probably both sides had glass. It is very well made and in excellent condition for age. If you open the white side and hold it up to the light - it looks pink because of the bloodstone behind it. It is 0.75 inch long not counting the loop.
