The 1/3s that fetch a lot and are highly sought after will have other mods...particularly the right combination of hci, dci, sdi. Others look for skill increase, some look for swing speed and/or damage increase, and most will want Enhance Potions (assuming use for pvp).
That ring there has already got 3 mods on it. Not sure how it all works as far as weight for imbuing, but at best you could imbue 2 additional mods. Given that, I think It's not really any better than something one could craft.
Sorry =\
