A pair of terminated transparent Tourmalines from vintage 1980 finds at Coronel Murta (Minas Gerais, Brazil). This Elbaite is also quite dichroic and best appreciated when rotated in front of a polarized light like a computer screen. The color ranges from almost colorless blue hue to a very dark green. In very good condition overall, this is nearly all facet grade clear and has fine well-developed striations. 17.5 grams and quite different from more recent Brazilian Tourmalines. This will fit at an angle in a perky box but not a 1 inch cube.
A super and unusual thumbnail gem crystal with a clear red Rubellite exterior that lets the green-blue inner core be seen like a racing stripe. Choice and better in person, there is a tiny bit of adhering matrix and one small clean contact with no damage. This crystal is also dichroic with a good color shift seen when rotated in front of a light source like a computer screen. Small but with a good display impact far larger than the size!
