PostPosted: May 03, 2020 11:10    Post subject: Pink amethyst?  

If anyone is looking for evidence that the rondinaire (according to Jordi Fabre, this the word for curmudgeon in the Catalan language and is a term that he has applied to me) has gotten too old to continue look no farther than the article “Pink amethyst from the El Choique mine, Patagonia, Argentina” by Rainoldi, Rossman, Di Martino and Oteiza in the March-April, 2020, issue of The Mineralogical Record (MR). The obvious nonsense of this title should have triggered an instant reaction by the rondinaire. It was not until I received an email from more alert readers calling this travesty to my attention that the rondinaire woke up and sprang into action. Shame on the MR editors for allowing this to go forward. They could have and easily should have requested that the authors rename this discovery pink quartz instead of pink amethyst. One of the authors in particular, Dr. George R. Rossman, professor of mineralogy at Cal Tech University, should have known better as he has long been a hero of the Gemological Institute of America. The GIA has a tradition of opposing blatant mislabeling, especially when it appears to serve little purpose beyond the enhancement of the marketability of a mineral or gem product.

The issue here, of course, is that the term amethyst has a very specific meaning, purplish quartz, and this has been the case at least as early as Theophrastus in the fourth century B.C. Amethystus was one of the twelve gem stones mentioned in the Bible used to adorn a linen bag. So amethyst has been amethyst for a very long time and it seems inappropriate for its meaning to be changed in 2020 A.D. We expect to see corruptions of long established meanings behind mineral names in the healie feelie (metaphysical) community because that is their stock in trade and where anything goes, but for a mineralogical publication that prides itself in promoting reliability in nomenclature this seems unfortunate. After all, the MR now has three editors plus a very involved associate publisher, any of whom could have stood up and said “Hold it guys, this is not right.” That this appears not to have occurred is truly unfortunate.

I am reminded of the, I think, mostly unsuccessful effort to relabel red beryl from Utah as red emerald. Yes, if you Google red beryl you will find numerous efforts to promote red beryl as red emerald. The same, to my disappointment, may be said of pink emerald, but I do not believe you will ever find an article in the MR about “red emerald.”

John, Of course this is what you are referring to. Two of my three examples acquired at the 2017 Denver show.
I was interested in acquired additional examples and actively looked for these at the recent Tucson Show, but never saw any hi end specimens.

There have been a couple of MinDat threads dealing with these. What they truly are and what to call them. I believe "pink" or "red amethyst" was considered a marketing term rather than being a truly accurate descriptive mineral term.
I too am surprised the MR used this term in their article.

I'm not really fond of marketing-driven names like "pink amethyst" and wouldn't advocate using such a term.
But they could have done worse: they could have called it "pink quartz".
Then the chaos would have been be perfect.
But luckily they do understand what amethyst, rose and pink quartz are (Fig.15 and text).
