The block is chosen wet
Rough stone is judged wet, where translucency and veining read true. We buy small — a block yields two or three mouthpieces, and the rest is offcut.
Jadeite hookah mouthpieces · 翡翠煙嘴
NEPHRA makes one thing: the mouthpiece you bring to the hookah. Each tip is cored from natural grade-A jadeite — 翡翠 — and pressed onto a turned titanium stem, so the part that touches your lips is cool, dense, unglazed stone rather than plastic or chrome.
Jadeite is the house stone. The same silhouette is cut four more times — white marble, snowflake obsidian, tiger’s eye and rose quartz — and no two blocks read the same.

The collection
One shape, cut five times over. Jadeite is the house stone; beside it sit white marble, snowflake obsidian, tiger’s eye and rose quartz. Every reference sold out in batch 01 and can be reserved for the next cutting.

Craft
A hookah mouthpiece is the only part of the pipe that touches you. We treat it like jewellery: the same jadeite grading, the same finish standard, the same refusal to hide a flaw under plating.
Rough stone is judged wet, where translucency and veining read true. We buy small — a block yields two or three mouthpieces, and the rest is offcut.
The airway is drilled with a diamond core bit under constant water flow, then lapped through six grits until the bore is glass-smooth. Nothing is coated, dyed or resin-filled — obsidian and marble get a slower feed so they do not chip.
The stem is turned from grade-5 titanium and pressed into the stone over a fluoroelastomer O-ring. Mechanical fit only — no adhesive sits anywhere in the airway.

FAQ
Yes — through the waitlist. Batch 01 is fully allocated, so every reference is now reservation-only. You pick a piece, leave your name and shipping address, and we contact you in the order reservations arrived when batch 02 is cut.
No. A reservation costs nothing and commits you to nothing. When your stone is ready we send photographs of it plus a shipping quote to your address, and only then a payment link. If you have changed your mind, ignore it and the reservation lapses.
US$200 per mouthpiece, shipping quoted separately by destination. Batch 02 is being sourced now — expect four to six weeks from the moment your stone is confirmed.
The jadeite references are natural grade-A jadeite, the same classification used in fine jewellery. Grade A means the stone has been cut and polished only: no bleaching, no polymer impregnation, no dye. Every piece ships with a card stating its stone type, and independent lab certification can be arranged on request.
Jadeite is the classic — dense, cool, and the reason the atelier exists. Tiger's eye and rose quartz are quartz-family stones, the hardest here at 7 Mohs, so they are the most forgiving day to day. Snowflake obsidian is volcanic glass: the darkest look, slightly softer. White marble is the softest at 3–4 Mohs and the most striking, but it marks if you are careless. All of them cost the same.
Any standard setup. The titanium stem is sized for 18 mm hoses, and a 12 mm adapter is in the box. If you run an unusual hose diameter, send us a photograph before ordering and we will confirm the fit.
Stone sits cool against the lip and stays that way through a long session — it draws heat away far better than resin, and unlike bare metal it never tastes of anything. It is also dense enough to give the hose a weighted, deliberate feel.
Jadeite is among the toughest natural stones and resists chipping remarkably well; quartz is harder but more brittle; marble and obsidian are the two to be careful with. Normal use, travel and cleaning are fine for all five. A fall onto a hard floor is not.
Yes. Send photographs and dimensions of your rough or your existing pendant and we will quote — we have cut customers' own jadeite, agate and petrified wood. Commission work runs four to six weeks and starts at US$320.
Worldwide, insured and tracked. Parcels leave Taipei within two working days of payment clearing; the exact cost depends on your country and is quoted before you pay.

Batch 01 is gone. Reserve a reference for the next cutting and we will contact you in order with stone photographs and a shipping quote — nothing is charged until you approve the piece.
