Tungsten rings can be expensive, it all depends on where you shop. If you go to the mall and look for a tungsten ring, be prepared to shell out about $150.00 - $300.00 per ring - they could even go a little higher than that.
You can also go online and find that at stores like TungstenFashions where you will find them for much less, more like $50.00 each.
Why is there such a difference in price? Stores like TungstenFashions or other online stores do not have the overhead like a mall store has. For instance, an online store has cheap rent since they can be in the middle of no-mans-land and still have huge sales. that in turn, saves you money! Online stores do have to pay for security guards, less insurance and on and on.... the point, all of that saves you cash and in turn, the prices are lower. It is really as simple as that.
So, are tungsten rings expensive? It all depends on where you shop.
