Shower, pool, sea: can I keep my jewelry in?

Our jewelry is designed to be worn permanently, including in the shower, in the pool or in the sea. ASTM F-136 titanium and solid gold are unaffected by water, chlorine or salt. You don't have to think about it. Ideally, do rinse your jewelry with clean water after a swim in the sea or in a chlorinated pool.

My piercing is new — can I wear this piece?

All our jewelry is made from ASTM F-136 titanium or solid gold, the only two materials recommended during and after healing. For a piercing that's still fresh, we recommend checking with your piercer before any change. Our customer care team and our piercers in our stores in France can guide you too.

Single or pair: what does the price include?

Each piece is sold individually, leaving you free to build your own combinations. When a pair is offered, it's stated on the product page.

Is this piece suitable for sensitive skin?

Yes. The ASTM F-136 titanium we use is nickel-free and recognized for its biocompatibility, which makes it well suited to sensitive skin. That's exactly why we chose to work only with materials of this standard.

Will my jewelry keep its shine over time?

Our materials are chosen for how they hold up over time. Titanium doesn't tarnish, and solid gold keeps its shine with no surface treatment. Unlike plated or gold-filled jewelry, there's no layer to wear away.

How do I choose the right size for my piercing jewelry?

Every piercing has its own dimensions, which vary with the area and your anatomy. Take a look at our size guide on the site, or contact us directly: our piercers and our customer care team can point you in the right direction.

The sizes shown are for your final jewelry, once the piercing has healed. The bar fitted at the time of piercing is deliberately longer: do not use it as your reference when ordering.

Illustration - How to measure your jewelry - Obsidian Piercing

Lengththe post only, from base to tip, without the ends

Diameterthe inside of the hoop, measured at its widest

Thickness1.2 mm standard · 1.6 mm nipple, navel, tongue · 0.8 to 1 mm nose

Which thickness (mm) should you choose?

The standard1.2 mm

We pierce at 1.2 mm almost every time, like most piercers. If a professional pierced you, your jewelry is very likely this thickness.

Pierced at a jewelry counter or with a gun?often 0.8 or 1 mm

You can wear a 1 mm labret, which fits that hole, or move up to the standard 1.2 mm with an insertion taper (a small cone that eases the jewelry through). When in doubt, measure the piece you are wearing.

Want a thinner hoop?1 mm or 0.8 mm

Once the piercing has healed (the point at which a hoop becomes possible), you can go for a thinner hoop, in 1 mm or 0.8 mm. For labrets, 1.2 mm remains the reference: going thinner is only useful to fit a narrow hole (see above).

Ear

Lobe

Bar (labret)1 / 1.2 / 1.6 mm · 6 to 8 mm

Depending on how thick your lobe is. The closer the fit, the more comfortable the bar.

Hoop1.2 or 1.6 mm · ⌀ 8, 10 or 12 mm

8 = close to the lobe · 12 = roomier

Hoop: can be fitted straight away, from the day you are pierced.

Helix

Bar (labret)1.2 mm · 6 or 7 mm

Fully healed? The shorter one will be the most comfortable.

Hoop1.2 mm · ⌀ 8 or 10 mm

8 = close to the cartilage · 10 = more open

Shorter bar: ~2 months (check-up visit) · hoop: 6 months recommended.

Conch

Bar (labret)1.2 or 1.6 mm · 7 or 8 mm

Hoop1.2 or 1.6 mm · ⌀ 10 or 12 mm

The diameter should clear the outer ear without pressing on it.

Shorter bar: ~2 months (check-up visit) · hoop: 6 months recommended.

Tragus

Bar (labret)1.2 mm · 6 or 7 mm

6 mm in most cases.

Hoop1 or 1.2 mm · ⌀ 6 mm

Shorter bar: ~2 months (check-up visit) · hoop: 6 months recommended.

Daith

Hoop1.2 mm · ⌀ 8 or 10 mm

Hoop: possible from the day you are pierced. A horseshoe is a better choice for the first few months, while it heals.

Rook

Curved barbell1.2 mm · 7 or 8 mm

Hoop1 or 1.2 mm · ⌀ 6 mm

Hoop: 6 months recommended.

Anti-helix

Bar (labret)1.2 mm · 5 or 6 mm

Hoop1 or 1.2 mm · ⌀ 6 mm

Shorter bar: ~2 months (check-up visit) · hoop: 6 months recommended.

Flat

Bar (labret)1.2 mm · 5 or 6 mm

6 mm in the vast majority of cases. The flat is worn with a bar only, never a hoop.

Shorter bar: ~2 months (check-up visit).

Industrial

Straight barbell1.6 mm · 30 to 40 mm

The length varies a great deal with your anatomy: the safest route is to measure the piece you are wearing, or to ask your piercer.

Nose & face

Nose (nostril)

Bar (labret)1 or 1.2 mm · 7 mm

7 mm recommended · 6 mm once fully healed · 8 mm uncommon

Body

Navel

Curved barbell1.6 mm · 10 or 12 mm

Nipple

18 mm exists but stays rare. It varies with your anatomy: measure the piece you are wearing, or ask your piercer.

Tongue

Straight barbell1.6 mm · 14 or 16 mm

The safest reference: measure a piece you already wear, or ask your piercer for its size. For personal advice, our piercers welcome you in our studios in France.

Our jewelry comes sealed in a hygiene pouch: check the dimensions through the packaging before opening it.

How to measure accurately

The most reliable method is still to measure a piece you already wear and that suits you. If you cannot measure it (a piece you are unable to remove, for example), ask your piercer for the exact size of the one they fitted.

Bar (labret, barbell): measure the post only, from base to tip, without the ends screwed on at each side.
Hoop: measure the inner diameter, from one inside edge to the other. Do not measure the outside of the circle, that is the most common mistake.
Curved barbell: measure in a straight line from one end to the other, not along the curve.

Jewelry thickness

The piercing standard is 1.2 mm, roughly the thickness of a paper clip. It is the gauge of most ear and face piercings. Areas under more strain, such as the nipple, the navel or the tongue, use 1.6 mm, which suits their healing better. 1 mm gives a finer look on the nose, the tragus, the rook or the septum, and 0.8 mm is reserved for fully healed piercings.

The most common mistakes

Forgetting the downsize. The bar fitted at the piercing appointment is longer than the final jewelry. Once the swelling has gone down, it has to be replaced with a shorter bar. At Obsidian, we take care of this at the systematic check-up, 2 months after the piercing in our studios in France. A bar that is too long catches, moves around and irritates the channel.

Underestimating how much swelling varies. The bar fitted at the piercing appointment is deliberately a little longer, to allow for the swelling of the early days, without being too long: an over-long bar catches and ends up irritating the piercing as well. Everyone reacts differently. More pronounced swelling, because you slept on that ear for example, can make the bar feel too short for a while. That is normal, it has nothing to do with the quality of the piercing, and your piercer will adjust the length if the discomfort settles in.

Switching to a hoop too soon. We recommend waiting 6 months before moving to a hoop, to limit the risk to healing. Cartilage that has not finished healing takes the change badly. Ask your piercer what they think of the state of your piercing. The lobe and the septum, for their part, take a hoop earlier.

Relying on the standards alone. The thickness of your cartilage, the curve of your ear, the depth of your conch: every anatomy is different. These recommendations are professional reference points, not universal certainties.

Healing: how long it takes, area by area

Area	Estimated time
Lobe	2 to 4 months
Helix, tragus, conch, anti-helix	6 to 12 months
Rook, daith	6 to 12 months
Nose (nostril)	3 to 6 months
Septum	3 to 6 months
Labret, medusa	3 to 4 months
Navel, nipple	6 to 12 months

A piercing can look healed on the surface long before it is healed deeper down. Stick to these timings before considering a change of jewelry.

Materials: as decisive as size

On a pierced area, the material stays in permanent contact with your skin: the wrong piece can irritate it, slow the healing down or trigger a reaction.

ASTM F-136 titanium is our reference material, and the one we recommend for a first piercing. Biocompatible and nickel-free, it is the grade of titanium used for medical devices: the skin tolerates it well, even on a fresh piercing.

Solid 14k and 18k gold is biocompatible too and remains a lovely option on a fully healed piercing. Titanium is still the safest choice during the early stages, however.

So-called “surgical” steel, like most common materials, is not biocompatible: we do not recommend it for piercings.

Every piece we offer, we fit it and pierce with it ourselves, every day, in our studios in France. That is the most honest guarantee we can give you.

Super 👍🏻

Vu les autres avis j’avais un peu peur mais je voulais vraiment cet anneau-là pcq je voulais aligner 3 anneaux : un classique, celui-ci, et un entièrement recouvert de strass, pour faire un petit dégradé.
Je le trouve pas si terne que ça. À la lumière du jour il brille bien. Effectivement il est plus foncé que sur la photo, mais le titane argenté c’est toujours foncé et pas aussi clair que de l’argent fin.
La fermeture est quasi invisible, mais facile à manipuler. Avec mes longs ongles je l’ai mis sans problème. J’ai pris un 1.2x10mm d’ailleurs.
En tout cas je le trouve trop choupi, j’ai hâte que mon 4e lobe soit cicatrisé pour mettre le dernier anneau. À voir comment il tient dans le temps mais ça devrait aller ☺️

Très déçue du bijou

Je suis malheureusement déçue du bijou reçu.

La description est très bien, il est fin comme je souhaitais, dessus rien à redire. Le problème vient de la couleur. Le bijou est terne et ne brille pas du tout. Il est gris foncé et non argentée. De plus, j'ai fait l'erreur de le sortir de sa pochette en plastique pour le voir de plus près. Mais cela suffit à refuser le remboursement même s'il n'a pas été portée.
Je me retrouve donc avec un bijou que je ne souhaite pas porter. Je suis malheureusement déçue de mon achat.

En ce qui concerne par contre la livraison, très bien, reçu rapidement et très bien emballé dans une boîte

J’adore

Cette fois encore, je ne regrette pas mon choix (c’est celui du haut) discrètement brillant, pas trop bling bling, top!

Très beau

Bijoux très joli et facile à mettre
Je l'ai installé au 2e lobe en épaisseur 1.2 et largeur 8

Incroyablement beau

Très beau piercing, je l’ai mis à mon conch (en 10mm), il fait vraiment son effet
Facile à mettre

Superbes !

Boucles super belles que j'utilise pour mes lobes, faciles a mettre et conformes a la photo / description. A voir avec le temps si elles restent aussi belles mais pour le moment c'est parfait !

Anneau très joli, à la fois original et discret !
Pris en 8mm, convient à la fois pour le lobe et l'Hélix.

Parfait

Ce bijoux est parfait, je l’ai mis au conch (10mm) et franchement il rend super bien !

Parfait !

J'aime beaucoup cet anneau, même si il a tendance à tourner un peu.
Il s'agit de la version titane en 8mm.

Je me suis trompée dans la taille à la commande j’ai quand même réussi à le mettre à un lobe ☺️

joli bijou

J’adore sa finesse et le diamètre 8mm me convient parfaitement

Ce bijoux est super beau ! Le clip a l’air de bien tenir
Comme sur la photo, parfait

Joli anneau discret mais qui fait son effet 😊

Incroyable, le Belenos a répondu à mes attentes, ni trop simple ni trop voyant, juste parfait. Avec le clip qui facilite la fermeture, j'aime. Je recommanderai à mes amies

Joli bijou

Joli bijou, idéal pour un lobe à assembler avec d'autres anneaux !
Livraison rapide

Belenos

J'adore, tout simplement !
C'est du 8 mm.
Et hâte que le serpent en titane revienne en stock ;)

Très joli, hyper facile à mettre et confortable. Livraison hyper rapide. Rien à redire !

Magnifique

Je l’ai pris en 10 mm et la taille est parfaite ! Un peu compliqué quand même pour passer l’anneau, ça demande un peu d’entraînement ! Il est discret et original :)

Très joli

L’alternance de petits clous et de zircons fait toute l’originalité de ce piercing. Pris en 8mm pour mon hélix :)

Très élégant. Parfait

Très beau!

La couleur

Je suis déçue l’anneau est presque noir et non argenté. Soit le bijoux est noirci soit la photo n’est pas contractuel

décevant!

Rien à voir avec l'image.
Le modèle argenté fait lisse, les strass ne ressortent pas, ils sont invisibles et surtout la couleur ne fait pas argenté clair mais plutôt argenté noirci.
Pour 32euros je suis très déçu de mon achat.
Je regrette

Très joli bijou sera offert pour Noël.

Déçu.

J’ai acheté ce bijou pour le mettre en guise de percing à la narine, dans les paramètres ce percing était précisé possible à cet endroit avec la taille nécessaire cependant le percing est trop épais et ne passe donc pas à la narine … Achat inutile pour ma part en plus d’avoir abîmé mon nez en essayant de le passer
