How to order

step 1. Choose your favourite charm or gemstone.

step 2. Choose what kind of jewellery the add-on is for. For necklaces/bracelets we will add a large jump ring so you can slide the add-on onto necklaces yourself.

for earrings The rings on top of the charms are 3mm in diameter and are a perfect fit for our basic hoop earrings. If your own earring has a different thickness, please let us know in a message so we can adjust the fit of the charm.

for a necklace/bracelet For a necklace/bracelet we will add an extra jump ring so you can slide the charm onto your piece yourself. If you'd like us to attach the charm to a piece of jewellery in your order, please let us know in a message with your order.

opal
Opal is a hydrophane stone, especially white opal, which means that it can change colour when it comes into contact with water. It's important to remove your opal jewellery before taking a swim, shower, or workout.
