Purple pyrope-almandine garnets

In early 2016 purple garnets from East Africa started to appear. The source was Manica Province in central Mozambique. The deposit is located about 60 km northeast of Chimoio, near Gorongosa National Park. The area is under the control of the Mozambican National Resistance (RENAMO), an armed rebel group.
What's special about these garnets is the color - an intense purple with red flashes that is called Royal Purple. The Mozambique material has strong color with extreme brilliance.

The garnets also display a color change, from grape under daylight to cranberry with magenta flashes under incandescent lighting.

The government of Mozambique has now closed the area to mining making further supply uncertain.
The material with the best color is found in smaller sizes, under 3-4 carats. Since the color saturation is so intense, larger stones are too dark. The highest grade material has come from the Mozambique deposit, with some stones coming from Tanzania. Both display the distinctive color change.

Black Argillite

Argillite Eagle box by Haida artist Bill Reid
Argillite is a fine-grained sedimentary rock composed predominantly of indurated clay particles. Argillaceous rocks are lithified muds and oozes.

The Haida carvings of Haida Gwaii (formerly the Queen Charlotte Islands) along the coast of British Columbia are famed aboriginal art treasures created from a type of a hard, fine black silt argillite.
Black argillite occurs in only one place in the world, at a quarry on Slatechuck Mountain on Graham Island. Graham Island is the largest island in the Haida Gwaii archipelago.

There is one distinct difference in Haida Art compared to other West Coast native art cultures, Argillite. Black Argillite is only found on Haida Gwaii and is carved by many Haida artists.
