Although I have a kind of chip on my shoulder for the way Pandora squeezed out Trollbeads (who, in my opinion, do it prettier and better and did it first, but are much less ubiquitous on the retail landscape), I give them credit for branching out beyond the add a bead bracelets.
They now offer a full range of pieces, including rings, necklaces and earrings. This simple ring is a narrow sterling silver band set with cubic zirconia stones, reminiscent of the Tiffany Etoile band (which comes in platinum and diamonds for considerably more). This silver version is USD$50; it is also available in yellow gold and CZ for USD$350. Both pretty on their own or good for stacking.
