Special Notes: Sugilite is named after Ken-ichi Sugi who first found it in 1944 in an aegirine syenite intrusive stock in Japan. The mineral is commonly pronounced with a soft "g", as in "ginger". However, as with most minerals, its pronunciation is intended to be the same as the person it is named after; in this case, the Japanese name Sugi has a hard "g", as in "geese"
