This malachite is probably the smallest crystal I'd ever want to see of the species, I admit, but it is STELLAR in quality! The 8 mm crystal is SHARP, gemmy, transparent, and intensely electric green in color. I have never EVER seen a malachite crystal so sharply formed. Neither had Charlie. He treasured this little guy, which lived in a drawer near his desk. He thought, and I agree, that thismight just be the finest malachite crystal around, for sheer gram-for-gram quallity!
