The Zimbabwe 1 Billion Dollar banknote that features the Chiremba balancing rocks in Epworth was issued in 2008 with a dimension of 148 x 74 mm in length and width. The note is equipped with a 3-mm gold-to-green OVI stripe with repeating RBZ to enhance its security features. The Zimbabwe bird pattern printed with iridescent ink changes from bronze to blue while the serial number on the left also changes color from red to bright orange when the note is placed under the UV light. The obverse side features the balancing rocks, stylized grains and cow in underprint, and the Zimbabwe bird in OVI. The reverse side features an Aloe excelsa tree and an elephant.
