NeoMetal Side Set Onyx Cabochon Gem End THREADLESS

Create your own, unique navel or nipple piercing - team this beautiful opal cabochon gem with a NeoMetal curved or straight barbell shaft.

Originally pioneered by NeoMetal, the push-fit design is by far the best jewellery to wear securely in a piercing. The threadless post is slightly bent to create a tight fit inside a post (not included). To remove or insert, just tug gently on the round gem end and it will come apart from the post.

NeoMetal's implant grade titanium is lightweight and nickel-free and a perfect option for long-term wear in new and healed piercings.  Each piece holds a lifetime guarantee against defects in workmanship!

To Fit Post Gauge: 1.2mm/16g or 1.6mm/14g
Bezel Colour: Highly Polished Mirror Finish (ask us about anodising!)
Gem: 1 x 4mm Onyx Cabochon (synthetic)
