TvåBlå literally means "two blue" in Swedish.
This ring is a close cousin to the Bluetongue® and Zirconium ring we also offer. However instead of dark grey Zirconium interior, the TvåBlå features a brilliant blue interior. Get it...Bluetongue® on the outside, blue on the inside...I'll show myself out.
The interior material in TvåBlå is a proprietary Black Titanium alloy. Once heated glowing hot, the Black Titanium turns a perfect piano black color. But if you catch it juuuuust in time you pass through a range of brilliant royal blue and purple just before it turns to the dark side.
As with the other Bluetongue® ring, this design features a spectacular patterning that is revealed when subjected to an acid bath.
