A colorful cluster of extraordinarily sharp crystals of this double-pseudomorph. Normally, such specimens consist of somewhat lumpier crystals due to the repeated pseudomorphism. The sparkles you see are brilliant reticulated cerussite twins, sprinkled all over the specimen. Note that the leftmost crystal as shown is actually still malachite, while the others are completely or mostly replaced by the rosasite. Where malachite does show, its deep green chatoyance is in stark contrast to the smooth sea-blue rosasite. Ex. Sussman, Dave Wilber, and George Holloway collections.
