Cheap, Cheap, Cheap!  Remember the toys you could find at the bottom of a Cracker Jack box?  The quality of this ring is equal to that.  They claim this is "TITANIUM", HOWEVER, I have a TON of REAL titanium jewelry and none of it is this light or destructible.  I ordered two of these thinking that they were titanium but I was quickly let down.  It's very light and I don't know what kind of titanium this is supposed to be... But it's definitely not the same kind as all my other titanium jewelry and definitely NOT the durable kind.  The stone fell out of one (My Husband's) in less than a week and he is a Radiological Technologist.  Meaning, these were not put through a deal of stress.  Both rings were easily scratched all over with-in two days of wearing them.  Again, with neither one being put under any amount of stress.  And let's not go there with the customer service here.  I FINALLY did get my money back for both rings so, I will stop there.  Just don't waste your money here.  Spend a little more elsewhere and get durable, REAL Titanium jewelry.
