Four crystal curve cartilage earring

14mm long sterling silver or hypoallergenic surgical steel curve design inset with three crystals on 316L surgical steel 6mm or 8mm bar with 3mm screw-on ball closure secured at the back of the ear.

Please note: The crystals in these earrings are glued in and should not be worn in swimming pools, baths, showers, saunas or in similar conditions. Please do not put the crystals into cleansers or germicides as it may also cause them to fall out.

Which ear?
The four crystal curve stud is designed to follow the curve of the ear so it comes in a left and right ear version. Please select the ear that the earring is for. So if you have your left ear pierced you'd need the left ear stud. The one exception to this is front/forward helix piercings where you will need to select the opposite ear for the earring to follow the curve correctly.

Crystal colours (shown in picture)
1 Pinks, 2 Crystal, 3 Blues, 4 Sapphire, 5 Rose

Post length
Cartilage studs are not adjustable so you need to choose the length of the post.
