About SugiliteHide

Ken-ichi Sugi

Formula:

KNa₂Fe³⁺₂Li₃[Si₁₂O₃₀]

Colour:

Purple, violet, light brownish-yellow, colourless in transmitted light

Lustre:

Vitreous

Hardness:

5½ - 6½

Specific Gravity:

Hexagonal

Member of:

Osumilite Group

Name:

Named by Nobuhide Murakami, Toshio Kato, Yasunori Miura, and Fumitoshi Hirowatari in 1976 in honor of Ken-ichi Sugi (杉健一) (15 May 1901, Kashiwazaki, Niigata Prefecture, Japan - 16 July 1948, Fukuoka, Fukuoka Prefecture, Japan), petrologist at the Imperial University Kyushu, who first found the occurrence of the mineral with M. Kutsuna.

Sugilite is an example of a mineral name pronounced wrongly more often than correctly. Named after Japanese petrologist Dr. Kenichi Sugi, whose name is pronounced with a hard "g" (as in "geese"), whereas most English speakers mispronounce it with a soft "g" (as in "gene"). This wasn't much of an issue when sugilite was just an obscure ugly greenish-yellowish-brown rock-forming mineral from Japan, but when it was found in South Africa as large quantities of bright purple lapidary rock and thousands of people in the gem trade started talking about it, the bad pronunciation became entrenched (Alfredo Petrov 2014).
