Curved Barbells

• Designed for multiple placements: Curved barbells in this collection are suited to navel piercings, eyebrow piercings, rook piercings, and daith piercings, covering the most common curved barbell placements in a single range.
• Two core gauges: The collection focuses on 14G curved barbells (standard for navel piercings) and 16G curved barbells (standard for eyebrow, rook, and daith placements), with bar lengths ranging from 6mm to 12mm across styles.
• Material range built for different needs: From implant-grade titanium curved barbells for healing and sensitive skin, to 316L surgical steel curved barbells for healed piercings, to gold curved barbells for a refined finish, each material serves a distinct purpose.
• Style range from minimal to decorative: Choose from plain curved barbells with ball ends, crystal curved barbells, opal belly bars, dangle curved barbells, and flat-disc styles, covering everyday wear and statement looks.
• Nickel-free options available: Nickel-free curved barbells in implant-grade titanium are available throughout the collection for those with metal sensitivities or active healing piercings.
• Threaded end compatibility: Most pieces in the collection use standard externally or internally threaded ends. Always check thread type before mixing tops and bars from different pieces.

• Navel styling: For navel piercings, dangle curved barbells and opal belly bars work best for summer and festival looks, while plain curved barbells with gold ball ends sit cleanly under clothing for everyday wear. A 14G curved barbell in gold is a particularly strong choice for a refined, fashion-forward finish.
• Eyebrow styling: Eyebrow bar jewellery in 16G surgical steel or titanium with small flat gem ends keeps the piercing looking intentional without overpowering the face. For a bolder look, a crystal curved barbell with a contrasting coloured gem top adds definition.
• Rook and daith styling: Because rook and daith piercings sit inside the ear, smaller and more discreet styles work best. A 16G curved barbell with a plain ball end or a small opal top complements the placement without competing with other ear jewellery.
• Layering with other ear piercings: When wearing a curved barbell in a rook or daith alongside hoops, studs, or flat back labrets in other ear positions, match metals for a cohesive curated ear. Titanium anodised pieces can be colour-matched across the lobe and cartilage.
• Material toning: Gold curved barbells pair naturally with warm-toned jewellery across the body. Titanium and surgical steel curved barbells sit cleanly alongside silver, white gold, and cool-toned accessories.
• Seasonal and occasion dressing: Dangle curved barbells and crystal curved barbells translate from day-to-night wear. Plain surgical steel or titanium styles are the practical choice for active wear, sport, and daily routines where snagging is a concern.

• Start with gauge: Before selecting a style, confirm the gauge of your existing piercing. Most navel piercings are 14G, and most eyebrow, rook, and daith piercings are 16G. Using the wrong gauge risks discomfort, poor fit, or damage to the piercing channel.
• Then check bar length: Curved barbell length is measured between the two ends along the inner curve. A standard healed navel piercing typically fits an 8mm or 10mm curved barbell. Eyebrow and ear cartilage placements generally fit a 6mm to 8mm bar. If you downsized after healing, measure your current piece before ordering.
• Choose material based on healing status: For healing piercings, select an implant-grade titanium curved barbell or implant-grade steel; both are nickel-free and skin-safe for active healing. For fully healed piercings, surgical steel curved barbells and gold curved barbells are appropriate. If you have a known nickel sensitivity, titanium is the safest option regardless of healing stage.
• Decorative ends vs. plain ends: Plain curved barbells with ball ends are the most secure and lowest-maintenance option. Dangle curved barbells and gem-topped styles are better suited to healed piercings where movement and styling are priorities over practicality.
• Thread type matters: Check whether the curved barbell uses internally or externally threaded ends before purchasing additional decorative tops. Mixing thread types can damage the threading inside your piercing.

Material suitability for healing piercings should always be confirmed with a professional piercer. Monster Piercing recommends implant-grade titanium or implant-grade steel for any piercing that has not fully healed.

• Clean regularly: Clean curved barbell jewellery with a mild, fragrance-free soap and warm water. Rinse thoroughly to remove all residue. For titanium and surgical steel pieces, a saline solution is also suitable for regular maintenance.
• Dry completely before storage: Pat pieces dry with a clean, lint-free cloth after cleaning. Moisture trapped between gem settings or threaded ends can cause tarnishing on steel and gold-plated styles over time.
• Store separately: Keep curved barbells in individual pouches or a compartmentalised jewellery box to prevent scratching between pieces. Gem-topped and opal styles are particularly susceptible to surface abrasion from harder metals.
• Avoid chemical exposure: Remove curved barbell jewellery before applying perfume, body lotion, sunscreen, or swimming in chlorinated pools or saltwater. Prolonged chemical exposure can affect the finish of gold-plated and acrylic styles.
• Check threading regularly: Gently check that threaded ends are secure, particularly on dangle curved barbells and styles with decorative tops, before and after wearing. Loose ends can be tightened by hand; do not use tools.
• Gold-plated care: Gold-plated curved barbells require more careful handling than solid gold or titanium. Avoid abrasive cloths and harsh cleaning solutions, which can wear the plating over time. Store away from direct sunlight and heat.
• Healing piercing care: If wearing a curved barbell in a healing piercing, follow your piercer's aftercare instructions. Do not rotate or move the jewellery during cleaning. Use only implant-grade materials in healing piercings.

• What is a curved barbell used for?

  A curved barbell is a body piercing jewellery style featuring a gently arched bar with threaded ends. It is designed for piercing placements where the bar needs to follow the natural curve of the body rather than pass through in a straight line. The most common placements for curved barbells are navel piercings, eyebrow piercings, rook piercings, and daith piercings.

• What is the difference between a curved barbell and a straight barbell?

  A curved barbell has an arched, banana-shaped bar, while a straight barbell runs in a flat, linear line between two ends. Curved barbells are used in placements where the tissue follows a natural body contour, such as the navel, eyebrow, and certain ear cartilage positions. Straight barbells are more commonly used in tongue piercings, industrial piercings, and nipple piercings. Using the wrong style for a placement can create pressure, migration, or discomfort over time.

• What gauge curved barbell do I need for a navel piercing?

  The standard gauge for a navel piercing curved barbell is 14G. Most professional piercers use a 14G needle for initial navel piercings, meaning a 14G belly button curved barbell will be the correct fit. Bar length varies, an 8mm or 10mm curved barbell is typical for a healed navel piercing, though a longer bar (10mm–12mm) is often used during initial healing to accommodate swelling. Confirm your current gauge with your piercer before switching jewellery.

• What gauge curved barbell do I need for an eyebrow piercing?

  Eyebrow piercings are most commonly pierced at 16G. A 16G eyebrow barbell with a 6mm to 8mm bar length is the standard fit for a healed eyebrow piercing. Longer bars may be used during healing. If you are unsure of your current gauge or bar length, measure your existing piece or ask your piercer before ordering.

• Can I use a curved barbell in a healing piercing?

  Yes, curved barbells are frequently used in healing piercings, particularly for navel and eyebrow placements. However, the material must be appropriate for a healing piercing. Implant-grade titanium curved barbells and implant-grade surgical steel are the recommended materials for active healing. These materials are nickel-free, non-porous, and biocompatible. Acrylic, glass, and gold-plated styles are not suitable for healing piercings. Always consult your piercer before changing jewellery in a healing piercing.

• What is an implant-grade titanium curved barbell?

  An implant-grade titanium curved barbell is made from titanium that meets the standards required for use in surgical implants, the same material classification used in medical-grade applications. It is completely nickel-free, extremely lightweight, and highly resistant to corrosion. It is the most widely recommended material for healing piercings and for anyone with a known nickel allergy or metal sensitivity. Anodised implant-grade titanium is also available in a range of colours without the use of dyes or coatings.

• How do I measure curved barbell length?

  Curved barbell length is measured as the internal length, the distance between the two threaded ends, measured along the inner curve of the bar. It does not include the threaded ends themselves. Common lengths are 6mm, 8mm, and 10mm. If you are replacing an existing piece, the easiest method is to remove the current barbell, unscrew the ends, and measure the bar itself with a ruler or digital calliper.

• Is a curved barbell the same as a belly bar?

  Yes, in common UK usage, a belly bar and a curved barbell for a navel piercing refer to the same piece of jewellery. A belly bar is a curved barbell sized and styled specifically for navel piercings, typically at 14G with decorative gem or dangle tops. The term 'curved belly bar' is widely used interchangeably with 'navel curved barbell' across the UK piercing community.

• Can I wear a curved barbell in a rook or daith piercing?

  Yes. Curved barbells are a suitable jewellery style for both rook piercings and daith piercings, particularly in the early healing stage. A 16G curved barbell with a 6mm to 8mm bar length is the standard fit for both placements. Smaller, more discreet end styles, such as plain ball ends or small flat gem tops, are better suited to rook and daith positions than dangle or oversized decorative styles, which can catch on clothing or hair.
