Billed as a wedding band, I think these would make really pretty every day rings, worn singly or possibly in a stack. Designer Shaesby offers the appealing option of customizing the metals used (and in some cases, though not this one, the stones ass well).

This ring features a .31 marquise diamond, a less common shape that fits perfectly into this sinuous band. You can choose from sterling silver, 18K yellow & white gold, 14K yellow & white gold, and platinum.

The price shown is USD $3,240, which I am assuming is the cost for gold (carat TBD by the buyer).
