Emerald v/h Ruytershof is one of the most praised stallions of his generation. Together with Harry Smolders, this son of Diamant de Semilly, became vice-world champion with the six year old horses. With the seven year olds Emerald has shown his class several times already in the stallions competition. At the start of 2012 Emerald graduated in the US to the 1.50 m level and he has proven over there that we haven't seen the last of him yet.

Andora P, the dam of Mandoro, whose bloodline goes back to the top jumping horse progenitor Indoctro, jumped at M level herself.
From the direct dam line also comes the international Valentino II (v. Numero Uno).
