These are okay, but beware of color changes in lighting...

On their own, these are very pretty and inexpensive.  However, when they reflect incandescent light they change color dramatically for the worse.

I read the reviews before I purchased, so I knew the problems others reported with the color - I took a chance.  They were right.  It is not the crystal itself, that is clear - I checked in sunlight and in a sunlight-spectrum light.  The back is not "painted" - you can see right through it, but it is a matte appearance.

Unfortunately, you are not going to wear this type of earring on a bright sunny day.  You are going to want to wear them to evening parties, in dim/indoor light.

Yep, mine reflect predominantly yellow light in regular use.  I don't look good in yellow.....do you?
