A very large specimen of ludlamite from the Brazilian Amazon, near the border with Colombia.  This is an exceptionally large and rich example of the species with an almost wet luster. In the page introduction I wrote at length about why they're special, repeating the same text in every individual description would just screw up the formatting and probably be annoyingly repetitive.... but I will say: you would be hard pressed to find more ludlamite on a single specimen anywhere else. A couple minor blemishes, saw marks on the side.
