Oh no, please dont feel that way. I wish i had this place when i was buying mine. As as many questions (of me, anyway) as you like!

I went thru the same thing. When i was returning mine for the shape not being eggy enough for me, the sales associate looked at me like i was nuts. But at this price point, i think perfection (at least in they buyers eyes) is required.
That said, i cant see the spots you are speaking of, but my eyes are not the best. Are they pinpoint spots or larger patches? I did see lighter pinpoints on at least one of the eggs i had. I never got far enough in my thoughts to see if it bothered me, bc it was shaped like a river rock. My lapis stone has a lot of light and darker spots, but that is indicative of the stone.
Are the spots only on one of the eggs? If not, is the other one still a contender?
