Need help identifying the two circles on my live rock.

I just noticed this on my live rocks. The rocks have gone from white, to brown, to green and are turning purple. These two circles appeared on a rock at the front of the tank.

The picture is a little blurry, but my guess is that these are Nerite snail eggs:

The center of each circle is kinda blue green. They are about half the size of a dime. My phone camera has a scratched lense.
