Royal Engineers Badge

As she does with many other military groups, The Queen has a brooch version of the badge of the Corps of Royal Engineers (design seen above) to wear when visiting the corps. It appears to be rendered in diamonds and enamel (potentially).

The Queen is also patron of the Royal Engineers' Association, which has a similar badge; this brooch was previously identified on this site as the association badge.
