16 Gauge Hypoallergenic Internally Threaded Crystal Circular Barbell
✓ Waterproof ✓ Hypoallergenic ✓ Tarnish Free
Give a classic circular barbell a sparkling upgrade with this Prong-Set Crystal Circular Barbell. Finished with a faceted cubic zirconia stone at each end, this sleek design combines balanced sparkle with a polished curved silhouette for a versatile piece that adds just enough shine without feeling overly decorative.
✨ Why You'll Love It
✔ Double Crystal Sparkle: Matching prong-set cubic zirconia ends create a beautifully balanced look with light-catching shine on both sides of the jewellery.
✔ Internally Threaded Design: The threading sits inside the bar, leaving the outside of the post smooth and creating a neat, streamlined construction when changing your jewellery.
✔ Classic Circular Styling: The curved horseshoe silhouette is a timeless body-jewellery design, while the crystal ends add a polished finishing touch that makes it easy to dress up or down.
💎 The Detail
Simple, sparkling and easy to style, this Crystal Circular Barbell gives a classic body-jewellery shape a more decorative finish. The two prong-set crystals create symmetry and shine at each end, while the polished curved bar keeps the overall look clean and balanced.
Available in Silver, Gold and Pink, it’s an easy option when you want the versatility of a circular barbell with a little more sparkle than traditional plain ball ends.

How is barbell length measured?
Straight barbells: Measure the wearable bar between the two balls or attachments. Do not include the balls or decorative ends in the measurement.
Curved barbells: Measure the wearable section of the curved bar between the two attachments.
Nipple barbells: Measure the wearable straight bar between the two ends. For decorative nipple shields or specialised designs, check the product specifications because the wearable length can differ from the overall bar measurement.

Everyone’s anatomy is different. If possible, measure jewellery that already fits comfortably.

Highly Recommend!!
"I reached out to Cherry Diva to enquire about some colors I saw in their product photos that weren’t listed as options. They responded quickly and let me know they could order the items directly from the manufacturer for me. The communication was excellent, they kept me updated every step of the way. Superb customer service from start to finish! Highly recommend shopping with them."
