Featuring our classic, original design. Made with silver caps, toughened glass and a stainless steel chain.
Tritium has a half-life of 12.3 years, meaning after 12.3 years the pendant will glow half as bright, and after 24.6 years will glow a quarter as bright.
Tritium costs $30,000 per gram, putting it in the top 10 most expensive materials in the world (of course it's in gaseous form in our pendants).
