A gloriously detailed orb pendant, in a mixture of yellow and rosy gold. 
I would wear this suspended on a longer chain - perfect for throwing on over a jumper. 
Tested as 9ct gold, partial hallmark for Birmingham, 1890. 
Weight approx 1.93g
Total drop approx 20mm
Width approx 14mm
Very good antique condition - some tiny pinprick dents to the central band.
