clear with sediment
I had some drilled stones that were clear except there was something that looked like sediment on the bottom. Like lightly stirred up sediment on the bottom of a crystal clear lake. I made a necklace out of these stones and gave it away as a gift. I don't know what those stones were called and I'm having trouble locating more of them.

Unfortunately, the description isn't bringing anything to mind except perhaps agate, which can take on a lot of different colors and varieties. You've probably already thought about backtracking to where you purchased or found them.
Good luck with finding them!!
