On my one strand there are a few that are too flawed to use, and there are about three that are really outstanding.  The rest are as described and very beautiful.  Even a mediocre Zircon faceted bead is an amazing thing and all of them sparkle brilliantly in light due to the accuracy of the laser faceting.  I love the strand I received, and hope to purchase more in the future.  The price is very reasonable.  Hoping that I'll get a bit luckier next time...that's part of the fun!
