My "high polish" (i.e., "silver-colored") titanium pieces definite look different from the steel. They're duller, darker, and maybe have more blue in them.

You could weigh them if you have a scale that measure small amounts, like a postal scale. The titanium should weigh less.

Thanks, i guess i'll try and compare them again in daylight

Weight will be the best way.

Titanium is darker in color than steel...grayer.

Implant Grade steel isn't attracted to magnets.

other than being lighter...much lighter, and the color being a "different" silver.
if there are beads or balls tap them with your finger nail....titanium kinda has a "plasticy" feeling to it when you do that. At least all of my Anatometal jewelry feels this way ha ha

will have to try that test!
