I bought a 17ct+ stone cut into a pentagon shape with a star cut into the back of it. It is a nice yellow, very good colour saturation, lovely lustre and loupe clean. It was sold to me as Topaz…however, after doing the citrine and topaz minicourses I’m questioning this. I’m going to a gemmologist next week, but in the meantime, let me know which you think it is!!
(I can’t test it myself as I don’t have a moh hardness tester or any proper tools yet)
