Utahite, Eyreka Hill mine, Tinlic district, Utah, USA. Specimen 8x6x3,5cm with Chervet and Deyrolle labels. Rare mineral, a hydroxy-oxide of tellurium, zinc and copper. Professor Chervet was an excellent chemist and no errors were found in his determinations. However here I have a problem because the colour of the sample is different from the references on the internet
