💎 The Detail
Simple, sparkling and effortlessly versatile, these Prong Set Crystal Stud Earrings put the stone centre stage.

Available in silver or gold, these 20 gauge (0.8mm) earrings feature 10mm straight 316L stainless steel posts, 5mm cubic zirconia and traditional butterfly backs. Sold as a matching pair and designed for compatible, fully healed earlobe piercings.

*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.
