I haven't had a chance yet to check out the Dana Kellin for Target jewelry collection in person, but the pictures on Target's site look beautiful. You can view the collection here; I've posted the link since like the Albertus hat collection, the landing page isn't prominently displayed on the site. [Way to promote your design collabs, Target!]
Note that there are some items that are available online only. While the collection looks pretty online, I'll have to inspect them up close to give them my thumbs up or down. It does strike me that this collection seems like a "mashup" of two past Target designer jewelry collabs - Temple St. Clair and Dean Harris - and since I already own pieces from both of those collections, I will probably pass on buying any Kellin items unless I really fall in love with something.
