Quartz is the second most common mineral on the surface of the Earth after feldspar. It is made of silicon dioxide in a crystalline structure. Quartz naturally forms colourless six-sided crystals, and is transparent or slightly translucent. Quartz that is milky or is coloured has impurities in it. Quartz that is a pretty colour is usually given a different name, like amethyst.
A Queen is the female ruler of a country or empire. You can become a Queen either by marrying a King or by being born into the position, not by being voted in by the people. You cannot choose to become a Queen. A man cannot become a King by marrying a Queen, he simply becomes a Queen's consort, and a woman who has become Queen by marriage stops being a Queen when her husband dies.
