Currently at $4451 on eBay, the Vertu Signature M may not have an app store or QWERTY keypad, but it does however, feature a front casing that is composed of “69 carats of scratch resistant sapphire crystal.” Auction page. Click here for first picture in gallery.

The back plate of the Vertu Signature uses a scratch-resistant fusion of zirconia ceramic and titanium, which is partly translucent to emulates the luster of lacquered wood.
