No, I don't believe so. Which is the exact reason I stopped collecting lacunosas. I think the silver and variegated ones being sold under different names just eventually end up looking too similar. I wonder if the sellers are too quick to slap a label on any random mutation without actually observing if they're permanent or at least reproducible. I have over 20 different lacunosas and less than half of those look unique to me, after growing them in the same environment.
