It's 6 letters long, contains only English letters, and is a real English word (a common mineral). It follows all the required rules - no proper nouns, acronyms, or special characters. The word is challenging because it contains the uncommon letters 'q' and 'z', and only has one vowel ('a'), which makes it tricky for the opponent to guess.
