This is one of the Brucite specimens from a limited find in 2017, with a yellow color - a first for Brucite. Normally, Brucite's color is white, which is why I selected this one showing a transition from the more typical white to a bright, lemon yellow color. The second reason I chose it - is that it's on a matrix, which is less common for these specimens. In fine condition.
