For the sake of conversations, and based solely on those pics, I 100% agree.
Also true that many photos we see online are manipulated in one way or another.
Thing is, I've seen pieces that look just like that. The stones I've seen that looked that color were generally Fancy Green Yellow. Or even Fancy Grayish Yellowish Green.
I do not believe any kind of foil could simulate whatever they're doing to get that wacky green ( and blue and other colors as well) besides enamel on the inside of the cup.
Cutters offering these pieces never give straight answers on exactly how many things they're doing to get these colors.
Maybe some sort of translucent substance on the back.
As an example, in the case of color treated pink diamonds*, there are treatments used that are not permanent in the sense that heat from a jeweler's torch can remove external coatings that are used in some forms of color treatment.
Just speculating- but why believe the methods used to get these colors are permanent in that sense?
* I was referring specifically to treatments done to natural diamonds in years past- before lab diamonds came to such prominence. Newer methods used on lab diamonds are not subject to the same considerations.
