Ritter Royals are special one-off instruments made with rare materials and frequently feature uncommon construction designs. For example, the body of "The Flora Aurum" is carved from a rare, solid piece of quilted maple. Its bridge, tuners, and knobs are hand-cast solid gold. Two flawless diamonds, totaling 3.3 carats, adorn the volume and tone knobs. Gold leaf covers the back of the neck and headstock. It has tiny green-diamond knob position markers and an ebony fingerboard with a Renaissance-inspired solid-gold flower inlay—each leaf decorated with a platinum-set black diamond. The nut was carved from 10,000-year-old Siberian mammoth-tusk ivory. The value of this instrument is estimated at $100,000.00.
