導入: Why Knowing Jewelry Types Matters
Whether you’re a seasoned piercer, a studio buyer, or running your own online store, understanding piercing jewelry is more than just recognizing pretty pieces. It’s about structure, 安全性, healing compatibility—and of course—what your customers are asking for.
それは感覚です, we talk to importers, wholesalers, and professional piercers across the globe. One thing we hear consistently: the better you understand the product, the easier it is to choose (and sell) the right one.
This guide is here to help you make those decisions with confidence. We’ll walk through all the major types of piercing jewelry—how they’re built, where they’re worn, what materials work best—so you can stock your shelves (and your trays) with jewelry that actually fits your customers’ needs.
1. Jewelry by Structure: How It’s Built Affects How It’s Worn
The internal engineering of a piece of jewelry might not be visible to the untrained eye, but it directly affects how easy it is to insert, how comfortable it feels, and how well it heals.
Here are the five most common piercing jewelry structures you’ll come across—and when to use each one:
🔩 External Threaded Jewelry
This is the oldest and most traditional type. You’ll recognize it when the threads (the screw part) are visible on the post. The decorative end or ball screws onto the externally threaded post.
Pros:
More affordable
Widely available
Cons:
Threads can irritate the piercing tunnel during insertion
Not ideal for fresh piercings
Best for:
Healed piercings where cost is a priority. Think budget-friendly nostril studs, lobe barbells, etc.
🧲 Internal Threaded Jewelry
A safer upgrade from external threading. Here, the threads are hidden inside the post, and the decorative top has a small screw that fits inside.
Pros:
Smooth post: easier to insert without trauma
Stronger hold for threaded ends
Recommended by APP (Association of Professional Piercers)
Cons:
Slightly higher cost due to more precision in production
Best for:
Fresh piercings, high-end studios, customers with sensitive skin. Most professional-grade labrets and barbells are internal threaded.

🧷 Threadless Jewelry (Push-Fit Design)
Threadless jewelry is one of the most loved innovations in modern piercing. It uses tension-fit mechanics—the post has no screw, and the top pin is slightly bent to hold itself in place.
Pros:
Quick and tool-free insertion
Ultra smooth surface = zero irritation
Easy to swap tops while keeping the post in
Cons:
Slight learning curve to bend the pin correctly
Not always compatible across brands
Best for:
Studios that want ease and elegance. Great for healed lip, nostril, トラガス, or helix piercings.

Clickers and hinge rings are structured like hoops with built-in clasps. You open them like a door hinge and snap them closed.
Pros:
Seamless, clean appearance
No lost parts—everything is attached
Comfortable and secure
Cons:
Hinges can wear out over time with repeated opening
May not work for thicker gauges or complex placements
Best for:
Septum, daith, ヘリックス, and navel jewelry. A must-have for fashion-forward customers.
🔘 Captive Bead Rings (CBR) & Seamless Hoops
These are the classic hoop styles, where a small bead “snaps” into place using tension or pressure.
Pros:
Timeless look
Beads can be decorative (gemstone, opal, etc.)
Cons:
May be tricky to open/close without tools
Tension can loosen over time
Best for:
Lobe, eyebrow, cartilage, and intimate piercings. Good choice for DIY-friendly customers.
2. Jewelry by Shape & Function: Matching the Right Piece to the Right Piercing

6. Jewelry Sizing: ゲージ, 長さ, and Diameter
権利を選択します size is as important as selecting the right material or design. The wrong gauge or length can lead to discomfort, migration, or even rejection of the piercing. Whether you’re a wholesaler, studio owner, or new enthusiast, understanding sizing standards is essential.
📏 Gauge (厚さ)
ゲージ refers to the thickness of the jewelry bar or post. It’s usually measured in American Wire Gauge (AWG)—the lower the number, the thicker the jewelry.
ゲージ | Millimeter (mm) | Common Use |
|---|---|---|
20g | ~0.8 mm | Nostril, ear lobes |
18g | ~1.0 mm | 鼻, ヘリックス |
16g | ~1.2 mm | Cartilage, lip, トラガス |
14g | ~1.6 mm | Navel, industrial, 乳首 |
12g | ~2.0 mm | Stretching piercings |
💡 ヒントの場合: Always follow the piercer’s recommendation or default studio sizing, especially for healing piercings.
📐 Length
長さ is the wearable area of a barbell or labret post—measured between the two ends.
Piercing Area | Common Length |
|---|---|
Earlobe | 6mm – 8mm |
Tragus | 6mm |
Lip / Labret | 8mm – 10mm |
Navel | 10mm – 12mm |
Eyebrow | 8mm |
Industrial | 35mm – 38mm |

Septum | 8mm – 10mm |
Nose Ring | 6mm – 10mm |
Daith | 8mm |
Nipple Ring | 12mm – 16mm |
Cartilage Hoop | 6mm – 8mm |
サイズが重要な理由
✅ Too short: Causes pressure, swelling, or embedding
✅ Too long: Leads to movement, 刺激, or snagging
✅ Right size: Promotes healing, 快適, and long-term wear
Many studios recommend initial piercings be done with slightly longer posts to accommodate swelling—then resized after healing.
7. Materials Used in Piercing Jewelry: Pros, Cons & Use Cases
When it comes to safety, 耐久性, and aesthetics, material is a key factor in piercing jewelry. The wrong material can lead to allergic reactions, delayed healing, or corrosion—while the right one can ensure both style and comfort for years.
