On March 6th, I attended the last performance of this series, and the cast was partly similar to that of March 5th.
In "Emeralds", Pujol was indeed a bit pale, and Karl Paquette lacked stage presence and had somewhat stiff arms, and I was disappointed by the rather unmusical "sicilienne" solo by Eleonora Abbagnato (replacing Nolwenn Daniel who was supposed to dance on that evening- I hope that she's not injured). Things improved a tiny little bit during her duo scenes with Yann Bridard- but, even though I was happy to see the rarely cast Bridard, I wondered why cast him in such a role, while he generally is at his best in roles with a lot of acting like "Le jeune homme et la mort". In the Pas de trois, I liked very much Christophe Duquenne clean style and joy of dancing (he also danced one of the four demi-soloists in "Diamonds", and it was a pleasure to see him lead the polonaise).
In "Rubies", Clairemarie Osta was dancing this time with Alessio Carbone and Emilie Cozette. I agree with Marc and Francoise about Cozette being miscast in that role, she looked a bit weak and bland, especially when compared with former performances by dancers such as Marie-Agnès Gillot or Delphine Baey. But as the main couple Osta and Carbone both were very good; it was the first time I saw Carbone in a big role (he was promoted to premier danseur at the last competition) and he danced it very well, with a lot of charm.
In "Diamonds", the main roles were danced by José Martinez and Delphine Moussin. Moussin was not as technically secure as Agnès Letestu, but she was more expressive and moving, and her partnership with Martinez (very elegant, and doesn't he look great in that silver costume?

) worked very well. By the way, Marc, could you explain why you think Letestu and Martinez are not well suited to those roles? I realize that I have seen very few casts in it (Martinez, Le Riche, Bart in the male role and Letestu, Gillot, Moussin in the female one) so am lacking elements of comparison...
Also the whole corps de ballet deserved to be thanked, as they were excellent during the whole ballet, and especially the impressive finale of "Diamonds".
