Science uses technical terminology to unambiguously describe materials whereas the jewellery trade used terminology to describe products and the World Jewellery Confederation - CIBJO is in the middle making sure the consumer gets a fair communication from the trade by recommending nomenclature practices as published in the CIBJO Gemstone Book. Rubellite is one of those trade terms and refers the pink to red-coloured tourmalines that have a distinct manganese-related pink to red colour in both daylight and incandescent light. Note that the term has the same Latin origin than ruby! Technically, tourmaline is not strictly a mineral but rather a complex supergroup that includes a few mineral species with gemmological interest and in the case of pink, three have been reported: elbaite (the most common), fluor-liddicoatite and rossmanite. Irradiation of pale pink tourmaline, oxidizing Mn2+ to Mn3+ and causing vivid pink to red colour, is a common trade practice being currently a non-determined treatment since the artificial irradiation-induced colour it is virtually indistinguishable from the natural irradiation-induced pink to red colour. The longtime colour-based verbal tradition have kept mineralogical terms away from the trade lexicon where a simple “pink tourmaline” or “rubellite” will do the job.

Scientific concepts are cloaked in beautiful words to appear fascinating even to non-experts. Few people would have appreciated it if I had offered them a liddicoatite (although they would have rolled their eyes at its beauty) These interventions of yours on the "Queens of Stone" are always so pleasant and interesting. Thanks again Rui Galopim de Carvalho 🙏🏻
