16kg Manganoan Sugilite, GIA Laboratory Certified, Smithsonian Exhibition Stone, I.Kurgan Royal Azel, Hall of Gems Smithsonian Museum 1981, Wessels Mine in Northern Cape Province, South Africa
Sugilite 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".[5]
The mineral is also referred to as lavulite, luvulite, and royal azel by gem and mineral collectors.[3]
