Rose Quartz....how large should they be?

[jcr1709]

Hi,

I've grown out two rose quartz -"pink" cherry tomato plants I started from seed, both seeds from the same source. Both plants are healthy, but one is producing rather small cherries and the other is producing fruit a quite a bit larger, about the size of a black cherry. I want to save the seeds, which is the "real" rose quartz?

Thanks,
J
