If you don't already know, the necklaces from etsy seller, Spike the Punch ( I have, name envy. ) might just be the most successfully promoted jewelry line to date for the site. I have no real facts or figures, but starting last summer these pieces seemed to be popping up on every cupcake + confetti blog ( my term for the under 30 set of fashion bloggers ) I'm not sure if she put the jewelry in their hands (gifting = smart marketing ) or if they stumbled across them on their own, whatever, it worked and now they're back ordered 3-4 weeks due to the mass appeal.

Don't they remind you of this, Tom Binn's necklace, a little? - but a wee bit less spenny. ( And mark my word, don't be surprised if you see something very similar popping up on J.Crew. If so, you know who they swiped the idea from. )
