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.

It took 8 years to find 11 red diamonds that matched close enough to be set together in this piece.
