The diminutive crown is made of solid brass, plated with 18 carat gold and then hand painted and finished.
Creating the master of the commemorative crown threw up some challenges, said DiamondGeezer.com’s company director and jewellery designer Luke Billing. “We started with designing the first quarter of it, then mirroring the approved version left to right and top to bottom to produce the whole model,” he explained.
“Then, using Gemvision’s Revo milling technology, the rapid prototyping robots carved an actual size master from a block of hard modelling wax. The whole process took nine hours with the robot mills carving every detail to an accuracy of 1/10 millimetres to produce the pixel-perfect manufacturing master.”
