Zirconium rings are good rings to choose from due to their relative inexpensiveness compared to other metals.

Their resistance to corrosion, durability and contemporary look also makes them great choices for wedding bands and any other type of ring. On top of that, the dark black finish also does not fade or change color.

Zirconium is incredibly hard and scratch-resistant. With a hardness level similar to that of sapphire, scratching a zirconium ring would be quite difficult. 

Titanium rings are a great choice due to their cost-effectiveness, durability, and strength-to-weight ratio. Zirconium rings are also great cost-effective rings that have a unique design with added toughness and a comfortable weight.

Both titanium and zirconium make excellent modern and stylish rings.
