I just discovered Anna Sheffield's jewelry line Bing Bang. It is gorgeous. I'm lusting after the Two Finger Diamond Ring (below) set with 14 diamonds in 14 karat gold. It's $1550. I probably won't be buying it, but j'adore.
The Arrow Two Finger Ring is gold plated with silver swarovski crystal detail. The price is much more reasonable at $215.
Check out the variety of designs below. A bit edgy & tough yet still feminine.
And these are just the rings! Check out the cuff below.
