I was definitely a fan of these earrings.  I ordered 3 pair to take on a vacation for wearing around in the heat/humidity/pool (yep, in the pool).  They looked great, and I had no degradation in quality after being in the chlorine.  My only complaint was the weight of 2 out of the 3 pairs.  The red crystal glass was fine, very lightweight.  But the Black Agate and the Gray Cat Eye Stone both pulled down on my earlobe.  Also, I read reviews before buying, so I knew the Red Crystal Glass was much more see-through and brighter (red-orangey) than is pictured, and I was happy with that, but if you're looking for that dark, opaque, almost burgundy color - Red Crystal Glass is not what you want.  I've attached a few pictures so you can see the size and the red glass in different lighting to see how the color goes brighter/darker.
