(+0.07;-0.90).
i think a swap typo between "0" and "9" has occurred....... thank you for reporting that... OTOH the same -0.90 value is reported on the GTpro software AND on "tables of gemstone identification" by Brigit Gunther though...... ..........."tables of gemstone identification" by Roger Dedeyne reports 1.95-2.25 values...... ciao alberto
