Piercing Area & Terminology

Piercing area name
    The forward helix is a beautiful piercing location, making the most of the small piece of skin located just above the tragus.
  • ROOK
    A rook piercing is located just below the flat part of the ear, in the ridge of cartilage that hangs below. This is an impressive and unique piercing to have!
    Daith piercings are one of our personal favourites at Beatti due to the beautiful front-facing clickers that can be worn, making a big statement to any ear look.
    A tragus is one of the most common piercing placements as the jewellery in this location can be easily shown off with a beautiful statement labret or a dainty hoop.
    One of the most popular ‘starter’ piercings after lobes, a helix is located at the top of the ear in the cartilage and provides lots of possibilities for the different jewellery styles you can wear.
  • FLAT
    A flat piercing is located on the flat part of the ear, it allows space to experiment with statement labrets including those with hanging dangles for an eye-catching ear look.
    A conch piercing is a popular option for those wanting to wear a hoop that orbits around the center of their ear, or for nestling a touch of subtle sparkle inside with a labret.
  • LOBE
    The one that gets us all hooked! A lobe piercing is the most common type of ear piercing, located in the fleshy part of the ear lobe and not typically too painful.

Earring Parts

When it comes to piercing jewelry, the three main specifications to consider are the gauge thickness, length, and diameter. These specifications play a crucial role in finding the right fit for your piercing.

Bar (Post) Lengths

The length (mm) refers to the measurement of the earring post itself, specifically the portion that goes through the earhole, excluding the threaded part.

Earring Lengths

Gauge (Thickness)

The gauge represents the thickness of the jewelry that passes through the piercing hole. It is also the size of the needle used for creating a fresh piercing.

  • 16G — Commonly used for cartilage piercings. (Eyebrow, Monroe, Tragus, Helix, Rook, Conch, Daith, Lip, Septum)
  • 18G — Can be used for both lobe and cartilage piercings.(Nose, Ear, Cartilage, Forward Helix)
  • 20G­ — You’ll find on traditional butterfly back earrings.(Nose, Ear)
Earring Gauge

Inner Diameter

The diameter refers to the measurement between the inner edges of a hoop or ring, excluding the jewelry's thickness.

Hoop Earring Backings


The standard hoop is a timeless classic that most people wear regularly. Its easy-to-wear and remove feature makes it a convenient choice.


The clicker closure offers the most secure fit, ensuring no fear of losing your earring. Its simple open, pull, insert, and click mechanism makes it effortless to wear.


Hollow hoops are literally made in the hollowed tube. It is very lightweight and thin, simply open them pull, insert the post into the hollowed tube.

Type of Threads


Threadless labret piercing is an alternative to traditional piercing methods. It features a flat back design, eliminating the need for screws. Instead, it utilizes a push-pin mechanism for easy insertion. With its comfortable and secure fit, the threadless labret provides a comfortable wearing experience.


Internally threaded labret jewelry has an inside-threaded post and a flat back, ensuring comfort for daily wear and sleep. It allows easy decorative end changes without removing the post, reducing irritation. This jewelry is safer to insert than external threading, but securing the end needs precision. Recommended for new piercings due to comfort and reduced irritation risk.


The externally threaded labret has a flat back and threads on the outside of the post. It's sleep-friendly due to its flat back but can be tricky to insert as it requires aligning the post with the piercing hole from behind the ear. Consulting a piercer for assistance is advised.

How to Use Threadless Labret

Insert the pin about one-third into the bar. The pin is pre-bent slightly to assist in secure placement.

Gently bend the pin by hand as demonstrated. The pin's tension ensures a secure attachment to the bar. Adjust the bend to achieve the desired level of tightness, as the more you bend, the tighter the fit becomes.

Push the pin fully into the bar post to secure the closure. The tension from the pin's bend keeps the top securely in place.

To remove, pull ends apart. If closure is tight, twist jewel head while pushing it away from the bar post. Simple and comfortable removal.
