Rubellite Treatments
Irradiation gives purple red colour. Gemologists can not detect the treatment. Both natural and treated colour can fade. - GIA, 2018

Color may be improved by irradiation. "Hot" pink to pinkish-red (often) result from irradiation of colorless, light green and pink varieties (not detectable) - Blue Chart Gem Identification, Herve Nicolas Lazzarelli, 2010, p 5
Mohs Hardness7 to 7.5
