JEWELLERY CARE & MATERIALS
JEWELLERY CARE & MATERIALS
A little care helps keep your jewellery looking its best. The right routine depends on the materials used in each piece, so always follow the guidance for its most delicate component.
316L surgical steel is strong and durable. Keep it clean, avoid harsh chemicals and dry it thoroughly after cleaning or exposure to moisture.
316L surgical steel is a durable choice for healed piercings. Surgical steel contains nickel, so titanium may be a better option if you have a known nickel sensitivity.
Material is only one part of choosing jewellery for a healing piercing. Gauge, length, threading, design and surface finish must also suit your anatomy. If your piercing is still healing, speak to a professional piercer before changing your jewellery.
Use this guide to understand stud earring sizing for healed earlobe piercings, including post thickness, gauge and post length. Whether you're choosing traditional butterfly back earrings or threaded screw back earrings, we'll show you how the measurements work and how to find a comfortable fit.
Typical Sizes for Earlobe Stud Earrings
| Earring Type | Common Gauge | Typical Post Length* |
|---|---|---|
| Butterfly Back Stud | 20G–18G | 8–11mm |
| Threaded / Screw Back Stud | 20G–16G | 6–10mm |
*Typical sizes are a guide for healed earlobe piercings only. Anatomy, piercing placement and earlobe thickness vary, so your ideal post length may differ. Where possible, measure an earring that already fits you comfortably.
Gauge / Post Thickness
| Gauge | Thickness | Commonly Used For |
|---|---|---|
| 20G | 0.8mm | Traditional stud earrings and many healed lobe piercings |
| 18G | 1.0mm | Thicker stud earrings and some lobe jewellery |
| 16G | 1.2mm | Thicker piercing-style earrings and threaded jewellery |
Post Length
| Length | Fit |
|---|---|
| 6mm | Very close fit for thinner earlobes |
| 8mm | Close, neat fit for many healed earlobe piercings |
| 10mm | Comfortable standard length for many traditional stud earrings |
| 11–12mm | More room for thicker earlobes or a looser fit |
Butterfly Back Earrings
Butterfly back earrings use a traditional straight post with a push-on backing. The butterfly back slides onto the post and can usually be positioned to give a comfortable fit behind the earlobe.
The post should leave enough room for the earlobe without feeling tight or pressing into the skin.
Threaded / Screw Back Earrings
Threaded earrings use a backing that screws onto the end of the post rather than pushing into place. This gives the earring a more secure closure and can help reduce the chance of the backing coming loose during everyday wear.
Always check the individual product specifications for the exact gauge and post length, as these can vary between designs.
How is post length measured?
Post length is measured from the back of the decorative front to the end of the wearable earring post.
The decorative front and butterfly or screw-on backing are not included in the post length measurement.
Everyone’s anatomy is different. If possible, measure a pair of earrings that already fits you comfortably before choosing your size.
I am absolutely delighted with my purchase from Cherry Diva! The price was fantastic and the quality is even better than I expected. Everything looks beautiful and feels really good quality. I was so happy with my order that I've just ordered another pair of belly button rings! I would definitely recommend and will be shopping here again. ❤️
