I am very happy with this set. It is an excellent value.  The color of my amethysts were definitely more pink than purple/lavendar, which I didn't mind b/c I like pink however if you're expecting purple, I doubt that is what you will get.  I also like the size.  They are not gaudy like a professional athelete but they are a decent size.  Very similar to a pencil eraser as another person stated.  I recommend these for the great value and for the fact that you can wear these anytime, anyplace.
