Star Ruby
 

Hi there, I know people who obtained Star Rubies on green beta, and they should definitely be classic, but the main jewel-selling vendor Amber in North Freeport doesn't sell them, neither does any other vendor I can find that's supposed to sell them :(

Amber should be selling them in unlimited quantities. I don't think there's any era errata on this, as far as I've seen.

They weren't added to vendors until July 1999 actually. See the Nilbog sheet for proof.
