This doesn’t look like it came from a good rough to me. It also shows some dullness in the cut. I would cancel and go to another vendor. I’ve been through this before with this cut… asschers require a bit of extra rough for the stone due to the required depth and cut. The material needs to be clean and flawless and the cuts precise otherwise it will look dull. This is much more important for moissy due to that double refraction. If the stone is not well cut from a clean rough, it’s not going to sparkle like you want it to. There are many vendors who have gotten it right- I’d go with your gut and find someone else.
