Diamond X

Definition and stakes

George Frederick Herbert Smith,  Gem-Stones and Their Distinctive Characters

“ The colour-dispersion is large, being as much as 0·044, in which respect it surpasses all colourless stones, but is exceeded by sphene and the green garnet from the Urals (cf. p. 217) . The lustre of diamond, when polished, is so characteristic as to be termed adamantine, and is due to the combination of high refraction and extreme hardness. Diamond is translucent to the X (Röntgen) rays; it phosphoresces under the action of radium, and of a high-tension electric current when placed in a vacuum tube, and sometimes even when exposed to strong sunlight. ”

Elizabeth Lewis,  At the Back of the North Wind

“ When his eyes came wide open again, there were no lovely figures—or even windows—but a dark heap of hay all about him. The small panes in the roof of his loft were glimmering blue in the light of the morning. Old Diamond was coming awake down below in the stable. In a moment more he was on his feet and shaking himself so that young Diamond's bed trembled under him.
"He is grand at shaking himself!" said Diamond. "I wish I could shake myself like that. But then I can wash myself and he can't. What fun it would be to see old Diamond washing his face with his hoofs and iron shoes!

Victor Appleton,  Tom Swift Among the Diamond Makers…

“ The adventurers looked at one another. The search for the diamond makers was becoming more and more dangerous.
“I say let's go on!” decided Mr. Damon, suddenly. “We want to locate that cave, first of all. Perhaps, when we do find it, we may see some easier way of getting to it than this. And if those diamond makers do attack us—well, I don't believe they'll shoot defenseless men, and they may listen to reason, and give Mr. Jenks his rights—tell him how to make diamonds in return for the money he gave them.”
