Okay you're right, sarcasm aside, I didn't put much thought into that.
I don't see any reason to have it equal other than laziness (on my part). It just irks me that you have these gems of pure crystallized magical essence, and there aren't people just crawling out of the woodwork to give you good money for them.
And no, I wasn't evaluating the worth of the gems in other game applications, I was only thinking Astral pearls would be worth better money because the essence is so pure. I see you complain about overvaluing the pearls, but you don't complain that perhaps water gems are undervalued, as I've seen numerous people state that water gems aren't as useful in the late game any others. Besides which, since pearls ARE so useful in the late game, wouldn't it stand to reason that convincing people to alchemize them for gold rather than wishing for Grigori (haha), is a good thing?
