Its diamond Gibson guitar, named “Eden of Coronet,” featured 11,441 diamonds, weighing in at 401.15 total carats, set in 1.6 kg (about 56.4 ounces) of 18-karat white gold, bringing its value to around $2 million at the time.
Coronet blinged out a guitar in 2016 as well, breaking the record for the most jewels on a guitar after setting 16,033 Swarovski gemstones, including topaz, citrine, rhodolite and cubic zirconium.
