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

On a well-healed piercing, 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 mm · 6 to 8 mm

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

Hoop1.2 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: usually 1 to 2 months · hoop: around 3 months, depending on healing and your anatomy.

Conch

Bar (labret)1.2 mm · 7 or 8 mm

Hoop1.2 mm · ⌀ 10 or 12 mm

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

Shorter bar: usually 1 to 2 months · hoop: around 3 months, depending on healing and your anatomy.

Tragus

Bar (labret)1.2 mm · 6 or 7 mm

6 mm in most cases.

Hoop1 or 1.2 mm · ⌀ 6 mm

Shorter bar: usually 1 to 2 months · hoop: around 3 months, depending on healing and your anatomy.

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: around 3 months, depending on healing and your anatomy.

Anti-helix

Bar (labret)1.2 mm · 5 or 6 mm

6 mm in the vast majority of cases.

Hoop1 or 1.2 mm · ⌀ 6 mm

Shorter bar: usually 1 to 2 months · hoop: around 3 months, depending on healing and your anatomy.

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: usually 1 to 2 months, depending on healing and your anatomy.

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

Hoop0.8 or 1 mm · ⌀ 7 or 8 mm

Hoop: around 3 months, depending on healing and your anatomy.

Septum

Hoop1.2 mm · ⌀ 8, 9 or 10 mm

8 = discreet · 10 = more visible

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

Labret / Medusa

Bar (labret)1.2 mm · 7 or 8 mm

Shorter bar: usually 1 to 2 months, depending on healing and your anatomy.

Smiley

Hoop1.2 mm · ⌀ 8 or 10 mm

Body

Navel

Curved barbell1.6 mm · 10 or 12 mm

Nipple

Straight barbell1.6 mm · 12, 14 or 16 mm

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, the check-up takes place about a month after the piercing in our studios in France, or after 15 days for a tongue piercing. The bar is usually shortened after 1 to 2 months, sometimes later depending on healing and your anatomy. 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. A hoop can be considered at around 3 months, depending on healing, placement and your anatomy. A straight bar moves little and lets the channel heal straight; a hoop, curved and more mobile, needs a channel that is already well formed. Your piercer can help you judge the right moment. 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	6 to 8 weeks or more
Helix, tragus, conch, anti-helix	6 to 9 months or more
Rook, daith	6 to 9 months or more
Nose (nostril)	3 to 4 months or more
Septum	6 to 8 weeks or more
Labret, medusa	2 to 3 months or more
Navel, nipple	6 to 9 months or more

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.

Your skin doesn't compromise

Piercing jewelry is worn in the shower, during sport, in your sleep. Materials that sit against your skin 24 hours a day aren't a marketing question. They're a health one. Certified biocompatible ASTM F-136 titanium, solid 14k and 18k gold: every material is chosen for how well your body tolerates it.

Super satisfaite de mes bijoux, ils sont magnifiques !😍

Simple et efficace

Pris pour un septum en 1,2 mm / 8 mm.
Très agréable à porter au quotidien, très léger, aucune irritation. Génial. Facile a flipper pour le cacher si besoin.
Un peu difficile à visser seule sans matériel, il faut bien mettre la petite boule dans l’axe

Super piercing !

- Envoie et livraison super rapide ! - Emballage impeccable !
✨Je l’ai fait posé par ma perceuse pour éviter tout risque de vis mal visée. Cela fait 5 jours il n’a pas bougé ! J’avais peur d’avoir prise la mauvaise taille car je m’y connais pas trop mais au final c’est exactement ce que je voulais, je suis trop contente merci Obsidian !🖤

(J’ai pris la taille la plus petite pour celles-eux qui se poseraient la question ✨)

Parfait 👍🏻

Parfait

Guide des tailles est très bien.
Bijou de qualité, seul bémol : il n'est pas facile à mettre, pas facile à viser.

J’adore

J’adore le rendu, plusieurs tailles disponibles, qui permettent de changer l’effet souhaité.
Aucun soucis de matière.

Impeccable

Je cherchais depuis un moment un fer à cheval pour le septum en coloris or. J’en suis très contente, jolie bijou de qualité et livraison rapide !

C'est le 3eme bijou pour septum que je prends sur ce site et je suis dans. La qualité est top et les bijoux sont trop beaux

Ce n’est pas la première fois que je commande sur ce site ( que j’ai découvert par hasard) et franchement j’adore bijou résistant le métal utilisé ne bouge pas d’un pouce nickel je recommande à fond 😁

Bonheur et 🍀 le piercing fer à cheval 🐴

Je me suis fait percer le tragus exprès pour pouvoir mettre mon fer à cheval. Je l’adore il se passe facilement et habille mon oreille parfaitement. Comme d’habitude livraison rapide et soignée. Merci à obsidian de satisfaire nos oreilles!!

Classique efficace

Bijou reçu rapidement. Qualité au rendez-vous. Premier changement de bijou septum pour moi : pari réussi ! Ma prothèse était 1,2 x 10mm, j’ai pris un 1,2x12mm car je le trouvais un peu trop serré et effectivement maintenant c’est parfait mon nez respire ! Je repasserai probablement une commande… Je recommande !

Parfait! Envoie rapide et soigné avec une petite lingette désinfectante pour le piercing. J’avais quelques douleurs au septum et depuis que je l’ai mis plus rien, donc ca doit vraiment être du bon titane. Très contente de mon achat je recommande vraiment comparé aux autres sites de piercing où j’ai eu pas mal de problèmes.

Expédition rapide et produit de très bonne qualité. Super le commerce en ligne quand on a pas de shop qualitatif pres de chez nous.

Qualité, rapidité d’envoi, je suis toujours aussi satisfaite de mes achats chez Obsidian !

Extrêmement déçu

Le site dit que cela peut être un piercing téton mais pas du tout.
Ce n’est pas fait pour, impossible de le mettre et commande non remboursable.
Je recommande pas du tout.

Mitigé

Je le trouve super beau je suis contente du résultat, mais j'ai mis 30 minutes à le mettre ce qui m'embête un peu. J'aime bien changer au gré de mes envies et là je me demande combien de temps je vais le garder sachant que je vais avoir énormément de mal à le mettre. Si j'avais su j'aurais pris plus grand. Ce serait peut-être judicieux de proposer un outil pour pouvoir le visser.

Très beau

Le piercing est superbe,mais il faut prendre le coup de main pour visser la boule

Rien à redire

Reçu avec du retard mais c'était à cause de la poste. Sinon c'est un bijou de très bonne qualité, livré dans une jolie boîte ! Je recommanderai sur ce site sans hésiter.

Belle qualité

Bonne qualité de bijou, facilité d'utilisation. Seul bémol, les boules à visser sont un peu imposantes

Joli bijou mais..

Fan depuis plusieurs années de la qualité. Je prend exclusivement mes percings chez Obsidian.
J'ai tenté ce bijou au tragus, il est très compliqué à mettre seule. Après beaucoup de patience, j'ai tout de suite aimé le rendu.
Malheureusement, au bout d'une semaine j'ai perdu la boule. Probablement mauvais serrage de ma part.

Déçu..

Les billes de mon piercing tournaient en continue sans se fermer

Joli

Très joli fer à cheval mais au bout de deux jours d’utilisation j’ai perdu une boule. Tout était pourtant bien mis, mais elle s’est dévissée peut être un problème du bijou…. Du coup je l’ai enlevé.

Doré - Smiley

Je l'ai pris en doré pour mon smiley. C'est très jolie. Par contre, comme tous les bijoux smileys il est super compliqué à fermer. Il est arrivé rapidement, dans un colis bien fermé.
Seul bémol, il faut bien faire attention à ce que les billes soit bien fermées, sinon elles peuvent s'enlever.

Fer à cheval - doré

Je ne l'ai pas encore porter mais le bijou est de bonne qualité et c'est pile se que je recherchais !

Les billes ne se ferment pas bien

Le pas de vis des billes est compliqué à fermer... Du coup il reste un petit espace entre la barre et bille ce n'est pas terrible.

Canon

Quali et très joli! Je valide

Très beau mais trop petit

Le sens de la vis est compliqué à comprendre mais la qualité est là. Malheureusement le bijou est trop petit pour moi..

Super contentr

Super beau piercing, qualité au top comme toujours, j’adooooore !!
