A simple graduating 'S' drop earrings look just like Christmas trees. 
These earrings have a drop of 1" (approx 2.5 cm) from the ball of the ear stud, to their bottom. If preferred, they can be swapped over onto a pair of my handmade ear wires, which have a rubber sleeve to put on the back to prevent any accidental losses.
All my jewellery is sent in a presentation box unless otherwise specified.
