Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

Here will go general remarks about lorandite specimens.

Lorandite is the main ore mineral in the thallium orebody at Lanmuchang, China, and its crystals there can reach 4cm, the world's largest.

Yes Alfredo, How can you be so lazy as to have not included these? OH, I can hear you think, not as lazy as the person who didn't put them in who started the project. Of course you are right.
