Doctor Who Promise Ring
This is a stunning top quality 2MM promise ring in deep ocean blue or silver made of tungsten carbide with engraved message “Together forever through time and space” or you can customise the message. Tungsten carbide rings are virtually indestructible and scratch proof. They are polished with a diamond compound, resulting in a polish and shine that will last forever. Tungsten rings offer the perfect combination of unbelievable strength with style and comfort. Tungsten rings are the most wear resistant rings available on the planet. Tungsten is about 10 times harder than 18K Gold, 5 times harder than tool steel, and 4 times harder than titanium. Tungsten measures between 8 and 9 on the Mohs hardness scale. Due to their extreme hardness, tungsten rings will hold their shape and shine longer than any ring on the market.
