The $250,000 bass guitar, The Ritter Royal Flora Aurum, was built by Jens Ritter, a luthier, or stringed instrument maker, from Germany.

This luxurious bass has a body carved from a rare, solid piece of maple while the nut is carved from 10,000-year-old mammoth ivory.

The fingerboard is decorated with a floral inlay pattern made of 24-karat gold. There’s even a black diamond set in platinum decorating each leaf.

The bridge, tuner buttons and knobs are cast in gold. The knobs hold an additional embellishment: they are both topped with brilliant-cut diamonds (3.3 carats).

Ritter began as a musician who couldn’t afford his own instruments, buying broken guitars and fixing them. When Madonna’s bass player rang his doorbell and asked to see his collection, he realized his hobby might be his life’s work.

Ritter makes about 60 handcrafted guitars each year. His line of custom-designed Ritter Royals is being sold by Wynn & Co. Jewelry in the esplanade at Wynn Las Vegas.
