RG & WG Rainbows have different sets of gemstones in them. The WG have much harder stones compared to RG in Mohs scales, my friend have a RG bracelet n the orange Garnet cracked. But from what I read & told you'll hear more issues on Rainbow rings than bracelets, I don't baby my WG Rainbow n wear it 24/7, gym, outdoor run, surf, cutting firewood, house work etc literally part of my limbs😅 I get more compliments on it than my RG 4 Diamonds. But like any other things, there'll be a 0.01 % bad batch but 99% of it perfectly fine. Lots of people have RG 🌈 bracelets n have no issues.
