There seems to be a tiny market for planet-themed items. We’ve written about Planetary Christmas tree ornaments and Planetary Glasses, and they’ve all been well received. Now we come across these Solar System Rings by Etsy seller JewelryThreeSnails. They feature each of our solar system’s planets, though we’re not sure about Pluto’s status anymore. It’s not really a planet, right? In any case, they’re not expensive, made from silver with an enamel, and will set you back $14 a piece or $129 for the set of 9.
