Rock of the Month: March 2022

Madagascar Rainbow Labradorite

Labradorite is a highly metamorphized variation of Feldspar; the Labradorite from this cut is comprised of incredibly high-quality semi-clear dark gray gemmy crystalline structure with few inclusions. Smaller portions of microcrystals create pale-colored bands running through the stones, providing a lighter background which allows a large quantity of microflashes to shine through. This creates an entirely unique effect which has not been seen before. In contrast, the larger dark-gray crystals provide full-body flash across the transitional gradient of color, including but not limited to deep greens, dark blues, teal, dark purple and lavender, magenta to lighter pinks, oranges, golds and yellows. On even more rare occasions, rich reds can be seen. One of the most unique features of the samples from this cut is that they show a biaxial color scheme related to the direction of viewing in which certain segments of the rock will show its flash from one angle, acting as an outline of a larger-bodied flash viewable from a secondary angle, giving rise to a unique ocular pattern similar to manmade holographics.
