Vertu is now taking orders (but only 8 of them) for the Signature Cobra, designed by French jeweler Boucheron. The Cobra features one pear-cut diamond, one round white diamond, two emerald eyes and 439 rubies. A somewhat cheaper version - the $115,000 Signature Python - is ruby-free. But you better buy now: Vertu says only 26 Pythons will be made.
