The Caravaggio Orange Ring by Maxim Voznesensky for Annoushka. Detailed, organic, and slap-in-your-face blinged out, it's a breath-taker, this one.
Crafted from 18K yellow gold, white diamonds and dark orange sapphires, this looks good enough to eat. But, the GBP17,500 you'll have to pay makes it a little hard to swallow. O_O *gulp*
