The colour is in the metal.
Grade 2 Pure Titanium — 99.2% pure, hypoallergenic. Coloured by heat, never plated. Handcrafted in Florence, Italy.
Why Titanium
Named after the Titans, light enough to forget you're wearing it, strong enough to outlast the person who buys it. Titanium is what surgeons put inside the body, because the body accepts it. That's the same reason it sits well on skin that reacts to everything else.
Gi by Giselle works exclusively in Grade 2 Pure Titanium — 99.2% pure, hypoallergenic, biocompatible. Not titanium steel. Not an alloy blended down to make it easier to work. The pure metal, which is harder to shape and worth the trouble.
How the Colour Is Made
The dark finish comes from heat.
Titanium reacts to it. Held at the right temperature, the surface of the metal changes — the oxide layer grows, and as it grows it shifts colour through the spectrum. Stop it in the right place and you get the deep near-black that runs through every piece in the atelier.
No dye. No pigment. No coating sprayed on afterwards. The colour is a change in the metal itself, made by hand at the bench in Florence, Italy — one piece at a time, watched, because a few seconds either side is a different colour entirely.
Why It Isn't Anodized
Most coloured titanium on the market is anodized: the metal goes into an electrolyte bath, current is applied, and the oxide layer is grown electrically. It's fast, it's repeatable, and it produces the bright blues and purples you've seen.
Heat-oxidation is slower and it can't be rushed. Every piece is judged by eye. Two pieces from the same batch will never be identical, and that's the point.
What you get from it: nothing plated on top, so nothing to flake or wear away, and no re-plating every few years the way white gold needs it.
The Three Finishes
All three begin the same way — the titanium is oxidized first. What changes is how much polish comes after.
Dark Luster
— fully polished. Dark, and still reflective; it catches light in every link and facet.
Matte Luster
— a matte base with a light polish pass on top. A quieter shine, between the two.
Matte
— no polish at all. Fully matte, no shine.
Caring for Your Piece
Every finish is oxidized, so every finish is cared for the same way.
Mix a drop of mild soap into warm water. Let the piece soak a few minutes, then work gently into the details with a soft toothbrush. Rinse in cool water and pat dry with a soft cloth.
Titanium is hard, but it isn't scratch-proof. Store your pieces separately, and take them off before anything abrasive. Avoid perfume, lotion and hairspray directly on the metal. That's the whole ritual. It doesn't need feeding, coating or professional re-plating. Size Guide & Jewelry Care → · Shop the collection →
