Available for sale we have here refurbished, repaired and sample or test rings. These rings are NOT damaged in any way. Scratches may be present (some may be slighly used/handled) but not visible with a casual inspection. The rings will have three already inserted tritium vials (green or ice-blue / 2mm x 6mm) depending on availability.
To ensure maximum protection, the tritium vials are encapsulated in resin and they are non-removable.
Tritium (symbol T or 3H, also known as hydrogen-3) is a radioactive isotope of hydrogen and one of the most valuable substances on earth, with a market price of 30.000$ per gram.
The Tritium vials used are light sources of gaseous tritium isotope, hermetically sealed in glass.
This radioactive tritium gas glows completely on its own, in a very safe manner, without needing to be 'charged' with light as required by most phosphorescent glow in the dark products. The glow will be subtle and visible in low-light conditions; the darker the better. It will not be visible in daylight or well-lit areas. The light produced is literally ''on'' at all times, it's intensity isn't reduced after a few hours and will last non-stop for about 20 years. This is truly a ''nuclear powered'' ring!
These rings can be worn 24/7 but the vials are made of glass and care is advised because shocks may damage them. Do not expose in situations such as diving, dropping them in hard surfaces, manual labor, extreme temperatures etc.
