The 1765c large oval pierced Symbolic Jewel.
A very large jewel which measures 9cm by 5 1/2cm.
All large oval pierced Symbolic Jewels are extremely scarce, however this is
genuinely rare as it is a very early example, the earliest I have seen.
The jewel has a Maker’s Mark, ID, from John Dempster (Delmester).
John Dempster was a silversmith who manufactured jewels in London in the 1760’s.
Examples of his work are known dating from 1760 and 1762.
