Description
The black obsidian bracelet 8mm, the reference size for this stone, not too bold, not too discreet, the one that suits most wrists without ever overpowering them. Every bead is precisely calibrated to give an even look all the way around the bracelet. Handcrafted from natural stones, this is the one you wear every day without thinking about it.
Bead diameter changes the whole look of a natural stone bracelet. Below 6mm, the effect gets too delicate, almost like a fine bead necklace. Above 10mm, the stone takes over and the bracelet becomes bolder, more masculine. 8mm is the sweet spot, the size most stone jewellery makers default to, and the one I recommend to anyone unsure where to start.
On this bracelet, every black obsidian bead is precisely calibrated to 8.0mm, a detail that sounds minor but changes everything in the assembly. Uneven beads, even by a few tenths of a millimetre, create gaps or uneven tension on the elastic cord. Precise calibration guarantees a perfectly round bracelet, with no slack, that ages better over time.
In crystal healing, black obsidian keeps all its traditional properties here: it’s said to act as a protective barrier against outside tension and support grounding at the root chakra. The 8mm size doesn’t change its supposed effect at all, it’s above all an aesthetic and comfort choice, for a piece you can wear every day without fatigue.

Handcrafted by Camille
Every bracelet is assembled by hand in my workshop, in France. For this model, I systematically sort the beads by size before stringing, a step many skip, but one that makes all the difference in how the bracelet holds up and looks in the end.
8mm is the size I string most often, almost by default, and it’s also the one that demands the most rigour: at this scale, the slightest inconsistency shows. Discover the story of the workshop.
“8mm is the size no one notices, and that’s exactly why it works.”, Camille
Care: a soft cloth is all it takes; avoid salt, knocks and prolonged water, and take it off before showering or exercising. All my care tips are in the cleaning guide.
