What is the thickness of my piercing?

In piercings, there are two sizes that are generally used: 16G or 14G (1.2 millimeters and 1.6 millimeters). You will have to choose between these two sizes for your ear piercings. The other sizes are used for different types of piercings, such as belly button piercings, nose piercings, etc.

At Luna, we offer exclusively 16G (1.2 mm) thick piercings, which are compatible with all ear piercings.

You may encounter the "Gauge" measurement system on the Internet. This is a measurement system used in the United States to determine the thickness and diameter of piercings. It is important to note that the Gauge measurement system is different from the metric measurement system used in most countries. Therefore, it is necessary to ensure that Gauge sizes are properly converted to millimeters to obtain an accurate measure.

It is important to note that in the Gauge measurement system, the higher the Gauge number, the thinner the piercing. This is opposite to the metric measurement system, where the larger the number of millimeters, the thicker it is. It is important to ensure that you understand and use the correct measurement system to get the correct size for your piercing.

For example: 1.0mm = 18G, 1.2mm = 16G, 1.6mm = 14G, ...

What is the length of my piercing?

The length of the piercing is the distance from the top of the straight bar (or stud) that goes through it to the bottom. This measurement does not include the base or plate it rests on or the attachments that are threaded onto the bar. It is important to ensure that you choose the right length for your piercing to ensure that it fits properly and is comfortable to wear.

What is the diameter of my hoop?

The diameter is used to determine the dimensions of jewelry that has a circular shape, like hoops or horseshoes. The diameter is measured from the inside and is the widest part of the jewel. It's important to make sure you choose the right diameter for your piercing to ensure the jewel fits properly and is comfortable to wear.

Size of horseshoes

Horseshoes are another popular type of jewelry for piercings, especially for septum, eyebrow, lip, and ear piercings like the daith and rook. These pieces of jewelry are shaped like a horseshoe or an inverted "U", with open ends and screw-on attachments, such as balls or spikes, that are fixed on both sides.

Just like with hoops, the size of a horseshoe is determined by its length and thickness. The length is measured along the internal diameter of the horseshoe, from one end to the other, excluding the attachments. The thickness refers to the gauge of the bar, which is the diameter of the material that passes through the piercing hole.

When you choose a horseshoe, you should consider the space needed for the curvature of the jewelry and the thickness of the skin in the piercing area. You don't want a horseshoe too tight, as it can cause irritation and hinder healing. On the other hand, if you choose a horseshoe too large, it can be uncomfortable and more likely to get caught in clothing or hair.

Size of studs or labrets (straight bars)

Studs and labrets are very versatile pieces of jewelry that are used in a variety of piercings, such as the lobe, tragus, helix, and lips. These pieces of jewelry have a straight bar with a flat or slightly curved end and a screw-on attachment at the other end. The attachments can be balls, gems, geometric shapes, among others.

To measure the size of a stud or labret, you need to consider the length and thickness. The length is measured from the base of the flat or curved end to the point where the screw-on attachment begins. It is important to make sure that the length is sufficient to accommodate the thickness of your skin in the area of the piercing, but not so long that it causes discomfort or gets caught in clothing or hair.

Banana Size or Curved Barbell

Banana barbells, also known as bananas or curves, are another type of jewelry commonly used in piercings such as the navel, rook, snug, and sometimes other areas of the ear. This type of jewelry has a curved shape with two ends where balls or accessories can be screwed on.

To measure the size of a banana barbell, you need to consider the length, the same as with a stud. The length is measured in a straight line along the curvature of the jewelry, from the inside of one end to the inside of the other. The thickness, like in other piercings, is measured in millimeters and can vary according to the piercing.

HOW TO ADJUST THE SIZE OF YOUR PIERCINGS

If you feel that your piercing is not fitting properly or is uncomfortable, you may need to change the size of the jewelry. Here are some tips to adjust the size of your piercings:

Visit a professional piercer: If you're unsure about how to change or adjust the size of your piercing, it's best to go to a piercing expert. They can assess the fit and recommend the appropriate size for your specific case.

Try different sizes and styles of jewelry: Some people may prefer smaller, more discreet jewelry, while others may want something larger and more noticeable. Experiment with different sizes and styles to find what best suits your preferences and needs.

Be patient and adjust gradually: If you're moving to a larger size, do it gradually and carefully. Do not force the jewelry into the piercing as this can cause irritation and complications.

Consider the material of the jewelry: Make sure the jewelry material is hypoallergenic and suitable for your skin. Some materials, like titanium, silver, and gold, are better for preventing allergic reactions and healing issues.

Choosing the right size for your piercings is essential to ensure a comfortable and secure fit. Take into account the specific measurements for each type of jewelry and consult with a professional piercer if you have any doubts or concerns. Remember that the quality of the materials and proper fit are key for a successful and uncomplicated piercing experience. Don't hesitate to experiment with different sizes and styles to find the perfect combination for your piercings.
