Althoow this was at one time incorrectly posted as an exploit, the person who did it...was retarded...Taffitite and Harmonagate also have always sold to the vendor for exaclty the same price 571pp after being cut...its like a 400-450 trivial cut...its not an effective way to make money unless some idiots sell the stones for cheap 100-300pp each....considering fails, you will come out ahead only if your a trophy holding master jeweler. For some reason they have changed the value of the cut Miragestones and not the other 2...just FYI, i assume this actually may be a mistake by sony.
