Description
The rainbow obsidian pendant, a black stone hiding colours, under light, it reveals pink, green and gold reflections dancing across its surface, invisible from a distance, dazzling up close. Worn as a pendant, this unique stone concentrates its whole play of light into a single point, right at eye level. Handmade with natural stones, it’s the one you wear for the surprise it holds for anyone who takes the time to look.
Rainbow obsidian owes its name to a precise optical phenomenon: tiny gas inclusions, trapped in the stone as it cooled, create a light interference that produces coloured reflections, pink, green, gold, sometimes blue, when the stone is finely cut and angled just right. It isn’t an applied tint; it’s a natural optical effect, unique to each stone.
Careful not to confuse it with celestial eye obsidian, which shows pinpoint blue-silver reflections in a star pattern, rainbow obsidian stands apart with its multi-colour spectrum and a more diffuse, almost oily effect across the surface of the stone. Both varieties are rare and require precise cutting to reveal their effect.
In a pendant, a single stone carries the whole effect, unlike a strand of beads, where the sheen is spread across twenty different stones. It’s the format that gives the best rendering of this variety: a stone wide enough for the eye to follow the shift of colours as it moves.
In crystal healing, rainbow obsidian keeps the protection and grounding properties common to all black obsidians, with a dimension of softness and lightness tied to its hidden colours, proof, in the stone itself, that light can hide at the heart of what looks dark.

Handcrafted by Camille
Every pendant is assembled by hand in my workshop, in France. Rainbow obsidian is one of the most delicate stones to work with: the coloured effect only appears from a precise cutting angle, and I have to orient each stone so the sheen stays visible once mounted as a pendant, at eye level, not just on the workbench.
It’s a stone that always surprises my customers the first time they see it under light, the shift from solid black to hidden colours never fails to land. In a pendant, that surprise is doubled: a single stone, the whole play of light. Discover the story of the workshop, or my whole collection of obsidian pendants.
“People often ask me if the colours are added. No, they were already there, hidden in the stone, I just had to know where to cut.”, 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 tips are in the cleaning guide.
