Our titanium colours are created through carefully controlled surface-finishing processes, including anodising where applicable. These processes enhance the natural character of titanium, giving each finish its distinctive tone and appearance.
Slight variations in colour, brightness and finish may occur due to lighting, screen settings and production batches. Multi-tone finishes may also vary between individual pieces, making each one subtly unique.
