The Mikimoto crown is made of both yellow and white gold, measuring from three to eighteen millimetres. It has a traditional Asian design based on the seven auspicious feathers of a Fenghuang phoenix using a mandorla flame design derived from traditional Japanese Buddhist iconography. The crown is decorated with diamonds totalling to 18 carats, with 120 naturally white pearls obtained in Japan, both South Sea and Akoya, giving a grand total weight of 29.7 carats. Due to its delicate nature, a security detail was attached to the crown wherever it traveled and insured for $250,000 USD against the risk of loss or damage.
