Ruby bracelets are powerful and meaningful jewelry accessories that you should have in your jewelry box. What makes them powerful is their glamorous and peculiar patina that goes easy on the eye. The color of ruby is such that it can excite the passions of everybody who takes a look at it. The intensity of red in this gemstone creates an appeal that none can resist. What makes ruby bracelets meaningful is, again, their patina, coupled with ruby's hardness rating of 9 on the Mohs hardness scale.
