was at one time an alternate name for the Scapolite
Group of minerals and at one time considered to be an intermediate
member of the Scapolite
Group, but is now an obsolete name. Although the
name Wernerite was rejected by the IMA,
some mineralogists believe it may be deserving of species status (see Dana, 8th Ed.).
As a testament to its historical standing, Wernerite was
listed as "the most important member of the scapolite
group" in the first edition (1896) of A
Dictionary of the Names of Minerals
by Albert Huntington Chester, Professor of Mineralogy
of Rutgers College.
was named in 1800 by Brazilian mineralogist José Bonifácio de Andrada e Silva (1763-1838)
Abraham Gottlob Werner (1749-1817), a professor of mining and mineralogy at the Freiberg Mining Academy,
was an influential teacher and his ideas shaped early geological
thought. He has been called the "father of German geology". Werner
is credited with describing and naming many minerals
including Anhydrite, Apatite, Augite, Boracite, Carpholite,
Celestite, Chlorite, Graphite, Grossular, Helvite, Hyalite,
Iolite, Labradorite, Laumontite, Leucite, Melanite,
Nephrite, Olivine, Omphacite, Prehnite, Pyrope, Rutile,
Torbernite, Vesuvianite, Vivianite, Witherite and Zeolite,
as well as many other names that are now synonym names
of other minerals.
September 1792, José Bonifácio de Andrada e Silva went
to Germany to attend the Frieberg Mining Academy to study under Werner.
José Bonifácio was a mineralogist,
naturalist, poet and professor of geology. He discovered
and named four new mineral species: Cryolite, Petalite,
Scapolite and Spodumen. He also named these eight mineral
varieties (or synonyms): Acanthicone
(syn. of Epidote), Allochroite (syn. of Andradite),
Aphrizite (a black variety of Tourmaline), Coccolite (syn. of Diopside), Ichtyophtalme
(syn. of Apophyllite), Indicolite (blue variety of Tourmaline),Salite
(variety of pyroxene) and Wernerite.
José Bonifácio named most of the minerals
which he discovered with scientific names derived from
Greek words, with the exception of Wernerite. The mineral
Andradite was named in 1868 by American geologist
and mineralogist James Dwight Dana (1813-1895)
in honor of José Bonifácio de Andrada e Silva.

typically white to gray, sometimes pinkish, and exhibit
bright yellow fluorescence under longwave UV light, and a duller orange-yellow under shortwave UV light.
Wernerite is commonly associated with Diopside which
fluoresces blue under longwave UV light. If you hover
your cursor over the picture at the top of this page
you will see the Wernerite gem exhibiting bright yellow
fluorescence under longwave UV light.
