What reading level is Quartz And Its Varieties Including Rock Crystal Amethyst Agate Jasper Agati book?
To quickly assess the difficulty of the text, read a short excerpt:
An apt anecdote or illustration would make serviceable breathing spots ; but, dear reader, any oddity that I may possess does not partake of the nature of the story-teller or artist.
Let us now proceed to the consideration of the quartz of Colorado.
The mineral locality known to collectors as Pike's Peak, covers an 31 area as large as the State of Connecticut. Quartz abounds in this region, but it is inferior in quality to the Swiss or North Carolina varieties, although local dealers prefer it ...for cutting purposes.
The smaller crystals sometimes show many interesting planes, such as steep trapezohedrons and many rhombohedrons higher than the unit. The "S" plane is quite common, and in one example a trigonal pyramid lower than the " S " plane was observed. The largest crystal of which I can learn as coming from this section weighed about one hundred and fifty pounds, and had nothing but its size to commend it.
In Black Bear Canon occurs interesting smoky topaz coated with small white opaque quartz crystals, which in form somewhat suggest rice, and they are called rice crystals.
