I just love hydrangeas! This style comes in two variants, one being more aqua and the other navy. 
The back of the earring is covered in a complimentary pattern - see the photos. Please note patterns may differ between products, there is a range on display.
 
These beautiful earrings are handmade from recycled coffee pods in my studio in Australia. Made with the utmost care and attention to detail, they are a lightweight product making them easy to wear.
