Truthfully the sapphire gem is a mix of breeds. It is not a breed, it is not going to have consistent traits that you get in a breed.
Even in a pure breed, there is a lot of genetic variance, hence the SOP. Cull anything that does not fit the traits of that breed, and eventually you get a very consistent appearance of the breed...but not fool proof, weird things still show up.
Both of your birds look bright eyed and healthy. When I have had a comb indicate health issues it has been noticeable in a full grown bird that is laying. If the comb looks blue, or fluctuates from red to pale pink back to red again, that can be a sign.
Bright red combs indicate laying, pale combs indicate immaturity, broody or molt, all natural occurrences.
