If I hadn't gotten these for free for review, I'd have been awfully upset and sent them back in a bit of a rage.  For one, they were shipped in a box as thick as a CD case, and arrived with the stems completely bent over.  More importantly, however, is that the diamonds look like cracked glass, with flaws breaking the surface of the gems, and causing them to look rather frosty.  I'd never pay for these!
Additionally, they come with a big "Made in China" tag, if that matters to you.
