Personally, I would choose either one of the save the wild necklaces if you are after a necklace. The Sterling silver one is $310 and the Rose Gold and Silver is $510.
The oui earring - and another one of oui or something else. Its $225 for one so $550 for two. Or the tiffany fluer de lise earrings as I think they will go with everything and not go out of style $700
For rings there is a lot available that I think are pretty awesome:
- tiffany wedding band in gold $475 or in platinum $675 could be an every day staple
- the graffiti love ring $525
- DBTY ring $700
-hardwear ball ring $575
-classic wedding band $650
- hardwear ball ring with a pearl $550
With bracelets I think MatAlliston who said the ruby r\and gold bracelet was spot on.
The other choice is to save up and wait for something that you really like and will last you a lifetime.
