In high quality blue rams, the second ray of the dorsal fin is elongated in the male. Females usually don't have this longer ray.

Females also tend to have rose-pink bellies.

The block spot on the side of a male blue ram will simply be black. On females, the black spot will have bright blue speckles.

IMO, females also tend to be considerably smaller than the males.

Congratulations on buying such a beautiful fish. They are one of my favorites. I have five (3 males, 2 females) in my 55 gallon. I'll try to take pictures of them during spring break --they are a sight to behold.

I agree with Jeff. I once had store bought rams, and they were impossible to sex. They were also prone to many diseases and died at an early age.

The five I have now are from two different local breeders. They are among the most beautiful fish I've ever had.
