Smalller sized than those home party jewelry lines.  My daughter purchased this as a birthday gift for one of her sisters.  It is over the top shiny ;)  Fits well, got a size 5 for a 13 year old girl.  Has the sparkle and wow factor.  Not really sure it could pass as "real" but that is not the product's job.  The metal band is sturdy and thick.  It will knock the socks off a teenager. If you give this as a gift and try to pass as real diamonds to a grown woman, your socks may be knocked off ;)
