This is short so it gets right to the good stuff. AHEM.
BUY YOUR RINGS ON AMAZON.
My husband did it (twice...*). *perhaps he would have been a bit more careful had it cost more than $20, but we will never know.
Mine is no longer available, but it was $600.* Similar bands we priced were in the $1500+ range.
*Here's a similiar one for $499.99!
As for his? A friend of ours was comparing his wedding band, which was pretty much exactly alike, and nearly choked on his drink when the husband said his version cost $30. Our friend's was $800 (I KID YOU NOT).
And, honestly, Amazon has such good customer service that, if you look at reviews and find a reputable vendor, it's worth a shot. They have not compensated me for this recommendation* - I am just one happy customer. My UPS guy can attest to that.
*Though Kiss My Tulle is an affiliate of Amazon.
