The Red Wonder Cross was designed by Oren Seren, Master Diamond Cutter of Seren Diamonds, and features 11 fancy red diamonds (0.42-0.93 carats), as well as colorless and blue diamonds, set in white gold.
Red is the rarest natural color in diamonds. The annual yield of pink to red diamonds would fit in the palm of one hand—and as few as one or two of these may be red. The 11 red diamonds in the Red Wonder Cross were all cut and polished by Seren.
The cross was completed on December 18, 2008. It has never before been seen by the public and will be on display at the Museum for six months.
