Bicolored


Another gem that has recently emerged from its cradle of creation. This spodumene crystal exhibits color zonation causes by the changing chemistry of the fluids from which it crystallized. Such color zonation is not wholly unusual, but rare enough to make a crystal more prized than some others.

This specimen displays its colors openly, while others from this same find are apparently "just" shades of pinkish purple---darkest along the length of the crystal, much like the deeper tones of a pane of glass seen on its edge. A dichroscope---a tool used by gemologists to determine pleochroism, the presence of multiple colors in a gem material---reveals in most of the apparently simply purplish crystals a direction in which they are also green, not discernible by the naked eye.

It is intriguing, one, that while the simplicity is often lauded and indeed sought by many, others find complexity captivating, and two, that while some objects (or people) appear simple at first, under closer scrutiny betray a more labyrinthine nature. Conversely, an elaborate comportment might belie a deceptively straightforward character.

Makes life interesting.
