This is fun, sparkly and relatively inexpensive and some days, that’s all you need. Ice.com has this sterling silver and cubic zirconia pendant (they say it’s set with 3.2 carats of CZ). It seems to indicate it comes with an 18 inch long chain, though it’s photographed on a fabric or leather cord. The pendant itself measures 38.1 mm x 47.9 (presuming they are counting the bail as a circular pendant should otherwise have the same height and width).
It’s selling for USD$58.95.
