My fiance and I just got a pair of matching tungsten rings online. You should check out their site because they offer great information. Here is a direct quote from http://www.tungstenworld.com/faq/
Can you remove the ring in an Emergency?
YES!
Rings made of extremely hard materials, like tungsten carbide or ceramic, can only be removed by cracking them into pieces with standard vice grip-style locking pliers. Standard ring cutters will NOT work.
Place vice grip-style locking pliers over ring and adjust the jaws to clamp lightly. Release and adjust tightener one-third turn and then clamp again. Repeat until a crack is heard, and then continue clamping in different positions until the hard material breaks away. Take care not to slide or rotate the cracked ring on the finger. If the ring contains an inlay of gold, the exposed gold can then be cut or clipped in the usual fashion.
Why choose Tungsten over Titanium?
Titanium lacks the implicit durability of tungsten carbide rings:
- Titanium can never have the same high gloss mirror-like finish that Tungsten can have, yet tungsten can also be finished in numerous other duller styles just exactly like Titanium.
- Tungsten jewelry is 4 times harder than Titanium jewelry. Titanium can be bent and is easily scratched.
- The weight of Titanium is almost non-existent. It does not have the same luxurious precious metal feel of heavier rings.
- The manufacturing process of Titanium is strictly industrial. It is easily produced using cheap materials involving almost no man-hours. Tungsten involves combining specific elements in up to 40 separate, labor-intensive processes to fabricate, refine, and polish each ring blank.
