From the original find at the Corrego Frio mine in the 1940s, this is a stunning brazilianite specimen with excellent color, glassy luster, gemminess, unique aesthetics and is associated with muscovite! The large brazilianite crystal is dramatic in person with a single shimmering face at over three inches in length. It is a gorgeous, textbook crystal with saturated, green-yellow color and astonishing internal translucency with a gemmy exterior. The termination faces display incredible luster while other faces shimmer due to very fine, vertical striations that create a wonderful play of light. This magnificent crystal is actually complete all around - a floater! It actually overgrew its own matrix, so to speak. It's obvious from the display side that this crystal grew in a pocket, however, the back of the crystal is deceptive: this piece was involved in a process called pocket rupture in which the crystal was dislodged from its matrix and the backside subsequently healed and dusted with numerous, small, glistening, well-formed muscovite crystals. In appropriately angled lighting, the reflection of continuous crystal faces can be observed in between the tiny muscovite crystals all across the back! To set off this amazing crystal, there is a large rosette of silvery muscovite on the left side composed of 1.0 cm or so crystals accented by two small, white albite crystals AND another, almost totally gem and complete, 2.0 cm brazilianite crystal! This pegmatite combination piece displays wonderfully and the rich, greenish-yellow color, great luster and transparency, and crystal form, are all at the top of the spectrum for this species. This matrix brazilianite is one of the most magnificent examples of its species I have seen for sale in many years, especially for the size, its perfect condition and the fact that it's a great combination matrix specimen!
