The gems list is the head of the list when comments are sorted by karma per vote (baseScore / voteCount), filtered for comments that received at least 3 votes. The only way to have this be higher than 1 is to receive a strong upvote, or a weak upvote from someone with >1000 karma. It can also be much less than 1, if the comment also got downvotes. I explicitly decided not to add a “controversial” sort, i.e. comments that received a lot of votes with karma (or karma per vote) close to 0.
