Basically all suffixes as long as it isn't a rare jewel, simply because some affixes can't spawn on rares.
Look in http://d2data.net/ under Prefixes and Suffixes. It's more accurate than the AS.
Oh, and giantturtle is absolutely right. "Of Ease" is a suffix so the only way to get other suffixes is if you have a rare jewel.
Looking at d2data.net,
we find that "ruby" is a prefix allowed only on magic jewels and "of freedom" is a suffix allowed on both magic and rare jewels.
Since we have 1 prefix and 1 suffix, we can find a magic "ruby jewel of freedom."
Since "ruby" is not allowed on rares, we cannot find a rare with both of those mods.
