aqua aura quartz does not have titanium on it , it is a layer of gold that causes the blue colors, and they won't come off, unless you grind them off :) and, yes, they are gorgeous ! one of my favorites for sure :)
Thank you. I bought the stones as stated above but it's nice to know that since I work with stones on a daily basis. I'll make sure not to state the next as 'titanium'. I appreciate that! Thanks again!
