TRUMIUM 2mm Rainbow Tungsten Ring
✓ Product data checked October 23, 2026
The TRUMIUM band is a slim 2mm tungsten ring with a high-polish rainbow finish and a classic domed profile. Tungsten is chosen for daily wear: the listing describes the ring as scratch resistant, cobalt free, hypoallergenic and resistant to fading, with a comfort-fit interior. The brand offers it as a promise or wedding band, but at this width it also works as a colorful stacking ring. The model listed here is size 6. At around $21, it is a low-risk way to give a ring that looks bright and does not need careful handling.
Why it makes a good gift
