Kutsuna.\r\n\r\nSugilite is an example of a mineral name pronounced wrongly more often than correctly. Named after Japanese petrologist Dr. Ken-ichi 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. 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).","2025-08-19
