Book Description
Each gem deposit-whether of primary origin in the parent rocks; or secondary as alluvial placers in valley floors, river gravels, or the sand of oceanic shelves presents an eloquent chronicle of the Earth's life story. It reveals to the expert the prodigious processes which formed the present crust of our planet, of which this volume discloses a small but exciting detail. The materials of the Earth's crust are the rocks. In this book, the author expounds on how they were formed, why they altered, why they became the cradles of precious gemstones, how they are categorized, and how they are now exploited by man. What initiates the growth of gemstones? How do they crystallize? Why do gemstones of the same species, originating from different sources, vary? What causes the occurrence of varieties? Why do diamonds, unlike other precious stones, occur not near the Earth's surface in its crust, but deep down beneath it in the upper mantle? These are only a few of the entrancing subjects discussed in this enlightening volume. The reader learns that the Earth is surprisingly alive and altering constantly-sometimes through slow and equable changes and at times by violent and tremendous cataclysms, events from which gemstones issue.

Book Description
Afterwit, agathism, ambsace, anacampserote, antepenultimate, antimony, and more! “When a word perfectly captures a human truth, humans respond to it in the same way that they respond to a beautiful melody. They smile. They nod their heads. They tell others of their discovery.” So says Simon Hertnon in his introduction to Endangered Words, and after wrapping your tongue around the lexical rarities he offers up to his readers, you’ll have to agree! Hertnon provides one hundred hand-selected rarities, and, in a virtuoso display of concinnity, breathes life into them with his lucid descriptions of their meaning and engaging examples of their usage. Perhaps you are an arriviste enjoying a newfound sense of nikhedonia as you demonstrate your sprezzatura in a given subject. Or maybe you are a desipientplutomaniac destined to a life of poshlost. If this doesn’t describe you, then take your pick of the many wonderful words in this book: Omnistrain Trilemma Aporia Or maybe these are all schlimmbesserungs! Thanks to Endangered Words, you no longer have to be at a loss for words or reach for the clichéd and commonplace. The English language is brimming with ambrosial alternatives, and this compendium offers the cream of the crop. Filled with words to be treasured for their elegant precision, from apophenia to zemblanity, Endangered Words is the perfect handbook for writers, an excellent resource for communicators, and an entertaining read for anyone with an appetite for the very brightest gems of the English language.
