Amethysts are clear (but not a fake looking clear), and the earrings are well made.

A word of warning about these earrings:
The first pair I received from Amazon was defective. One earring contained a clear stone, and the other was cloudy. The difference was so drastic, they looked like they ought to belong to different designs. Amazon replaced the earrings without any hassle. They even paid for return shipping, as per their policy.

The second pair was lovely with two clear stones. The earrings and the stones look small and delicate (in a fine way, not flimsy). I've purchased Sajen designs from Amazon before, and the pieces are always well-made. Unlike some of Amazon's other jewelry, the Sajen pieces always look exactly like the photo. This was the first time I've had a problem with their jewelry, and I hope it was just a fluke.
