Sotheby’s is set to highlight two pieces featuring colored diamonds at its upcoming Magnificent Jewels sale in Geneva, with each expected to bring in up to CHF 1.8 million ($2.1 million). 

The first is a cut-cornered rectangular mixed-cut, 1.44-carat, fancy-red, I2-clarity diamond ring. The other is a brilliant-cut, 16.73-carat, very-light-pink, VVS1-clarity diamond pendant. Both will go on the block at the November 13 sale, Sotheby’s said last week.
