Quilted calf leather upholstery.
Jet black PVD-coated grade 5 titanium.
Black ceramic pillow detailing.
No, it's not the options list on the latest Rolls-Royce - these are some of the design features on the £13,700-build 'Pure Jet Red Gold' edition of the Vertu Signature Touch Phone.
The British luxury gadget maker has never scrimped on details (their £10,700 Bentley model had an audio system tuned by Bang & Olufsen), but the new Signature Touch range takes the opulent biscuit.
Each of the volume control keys, power key, screws, pillow trim and back plate rails are constructed from red-gold, contrasting with the black leather and titanium structure. A folding 'gull wing' rear gives access to a MicroSD card slot and SIM card slot. And the ringtones? Recorded by the London Symphony Orchestra, obviously.
As for the 'phone' itself, it runs the latest Android (Lollipop 5.1) on a 5.2-inch HD screen, with a 21 megapixel rear camera. The massive price tag also gets you access to Vertu's concierge service (for 18 months) and access to exclusive Vertu 'cultural events'.
And if all that sounds a bit much, you can get the Jet Calf model for a bargain at £6,500.
