..they are tiny. The picture does it too much justice - the biggest diamond you see in the picture is probably about the size of a small pea, and that is pushing it. The vast majority of the diamonds are tiny, similar to bread crumbs in size.
They're still beautiful and come in a nice colour though, excellent for people who have turquoise as their birthstone or just a colour they adore. The bag is fairly sizable, bigger than the palm of your hand. It does make a nice decoration for weddings and such, or to fill a bag which you've hidden jewelry in (which is what I've done) so they definite have value.
Worth buying for the reasons I put, but you'll want to buy many bags if you want to decorate entire rooms and stuff. You don't get many for the price. You get enough to justify it somewhat, though.
