What grade is United States's Purple Alabaster?
I do not have information on the grading system for US Purple Alabaster. However, alabaster is a soft and easily carved stone, and its value is based on its quality, size, and finish. Alabaster is typically graded based on its translucency, color, and purity. The finer the texture, the cleaner the color, and the greater the translucency, the higher the grade.
