Crown jewel

Weighing 342 carats (about the size of a tennis ball), the Queen of Kalahari diamond was among the largest ever discovered when it was unearthed in 2015 at Botswana’s Karowe mine. Certified as D colour, Type IIA (a certification given to less than 2 percent of gem-quality diamonds), the massive stone was acquired by Chopard and cut into 23 pieces - five of which weigh more than 20 carats. The fruit of this process is the six-piece Garden of Kalahari collection, which comprises a convertible necklace, earrings, a bracelet, two rings and a watch. The necklace is the crown jewel, boasting three diamond drop pendants crafted in heart, pear and brilliant cuts. The mismatched earrings are another highlight, featuring one pearand one heart-shaped diamond.
