As Jewelmint.com's newest guest curator, Cedella Marley's endorsing a piece that's not just playful but also play-able: the Fine Tune necklace.

In addition to the asymmetric bead details on the side, the perfectly slouchy chain and that intangible "this old heirloom?" quality, the necklace's whistle charm actually works.
And while the necklace clearly pays tribute to Marley's musical heritage, it also pays half of the proceeds to her family's charity organization, 1Love.
Charming, charitable and, well, fun? Music to our ears. Buy it here for $29.99.
