Will this ring turn my husband's finger green?

No, tungsten doesn't turn your finger green.

will it scratch glass

It WILL scratch other metals/coatings. I have to be careful with things like the stainless handles on our kitchen appliances, as well as faucet handles. However, the ring itself is extremely difficult to scratch. I work with my hands doing a lot doing remodeling projects and wrenching on my Jeeps, and after years of that kind of abuse it has no visible scratches.

Is this ring true to size?

No I measured my finger with a ring sizer and got a 10.5 so that’s what I ordered and when it came in it was super tight I could barely get it on and off that’s how tight it was I ordered a size 11 hopefully that one will fit correctly when it comes in

Is this ring cobalt free?

Hi, this ring doesn't contain any cobalt, the material is 90% of tungsten and 10% of carbide and nickel.

Excellent value

Absolute no brainer. These rings are well made, very comfortable and a great deal at less than $30. Exact same ring at my local jeweler was $500.
