Some of the specimens have other colors showing including blue, red and gold.

I didn't understood completely, what you would like to discuss here.

I wanted to show how beautiful a polished specimen is in Nuummite. I found many dealers at the Tucson Gem Show selling stones as Nuummite from China and other places around the world. It is clear from the definition on the page for Nuummite that it only comes from the one location. What do you think?

I don't want to get into the debate of trademark names for material from specific locations, but I do believe that the Greenland material is unique in the assemblage and how it presents, although there is a similar look-alike that is easy to distinguish once you know. I see there is also "fake" Charoite now as well, another specific location type material.

Isaac,


I do not think that Mindat can decide the use of unapproved varietal names of minerals. It is hard enough to keep up with the accepted international nomenclature. From a mineralogical pont of view any anthophyllite/gedrite mineral with a schiller similar to "Nuummite" from Greenland could have the same name. Similar cases occur with other varietal names. "Thulite" is a varietal name originally placed on a a pink variety of Zoisite from Norway (Thule is an old name for Norway) but has since been used for similar coloured Zoistes from many other localities. But I have also seen "pink Tanzanite" being used for the same colour variety of Zoisite from Tanzania. I just shows how confusing the use of varietal and trade names can be. For Mindat the most important task is to present a link for these varietal names to the correct mineral name.
