I'm not sure what this was really used, but the consequences can be predicted.
Since the diamond is, of course, very hard, but, at the same time, very fragile (these are two different parameters), then It is quite time consuming to prepare powder from diamond, but it is possible.
Further, in a thick drink, perhaps this suspension will not settle. One can even assume what exactly can be added to the drink to reliably keep the suspension from settling to the bottom, but I will not, because you never know who will try :)
It would be incorrect to compare diamond powder with sand on the beach, since grains of sand are often doused with water. And here is a powder of very sharp small particles. Once in the esophagus and further throughout the body, they will make many small incisions, which, as a result, can cause inflammation, for example, peritonitis and, yes, in conditions of poor medicine, painful death.
I'll ask a slightly different question. And why is brilliant green called diamond? Dust is brilliant, it is most likely not diamonds crushed into dust, but another substance (for example, hydrocyanic acid extracted from cherry pits. Or some other exotic poison.). Perhaps there was no escape from him.
I don’t understand ... why bother with a diamond - a very hard, rare and apparently expensive mineral ???
If we can crush Glass, it also does not dissolve and cuts tissue ..
As you know, coffee has the ability to speed up metabolism, the same metabolism, together with small particles of one of the hardest substances on the planet (and perhaps not only), it turns out an excellent murder weapon, secretly, invisibly and effectively)
Everything ingenious is simple
Nonsense! With dirty vegetables, fruits and the wind, a lot of sand of various origins, including quite spicy, gets into our food. Therefore, either some poison was hidden under the diamond dust, or crushed glass, or someone had a fantasy.
In general, in the East, execution for officials was realized in the form of a silk lace on a precious tray on which the offender hanged himself, or he was strangled by it.
The guilty or objectionable court sultan personally gave coffee to which they had previously poured small diamond crumbs. It was believed that this even made the coffee especially tasty. During the day, almost weightless diamonds made thousands of tiny cuts on the walls of the unfortunate victim's intestines and esophagus. A week later, the doomed was dying of internal bleeding and peritonitis.
I heard a legend that if you add glass dust to food, then a blood clot will form in a person's blood in a few days and, accordingly, he will die. There may be some connection between glass dust and diamond dust.
Digesting sources found in English: because diamonds were believed to have incredible toxicity. Pliny the Elder (23-79 AD) in his "Natural Science" wrote that "the diamond dominates all other poisons, in comparison with which they are simply powerless." Therefore, its crumb was also considered poisonous.
However, in parallel with this, one of the most popular ways to steal diamonds and polished diamonds was swallowing.
Paracelsus, Turkish Sultan Bayezid 2, Roman Emperor Frederick 2, Pope Clement 7 are allegedly among those allegedly poisoned by crushed diamonds / brilliant dust ... Some sources provide information that diamond dust was mixed with arsenic. Which can serve as an explanation.
The option of voluntarily swallowing large quantities is indicated as a method of execution for theft.
This is most likely nonsense. A diamond is just carbon. The crystals are hexagonal, all corners are obtuse (this can be clearly seen on cut diamonds - the crystal lattice allows you to get almost exclusively obtuse corners). Special hardness is also not necessary here - ordinary glass is also harder than any tissue in the body and gives sharp chips. Most likely, due to the giant surface of finely crushed carbon, it will react with some substances in the intestines and simply dissolve or bind with feces - just like activated carbon.
Sorry if disappointed.
I recently heard this legend (or not a legend) from one guide in Crimea. The khans were executed in this way, but not with diamond dust, but with crushed diamond. At the same time, it was not secretly poured into the coffee as a poison, but was brought as a "gift" diamond chips, wrapped in cloth and the guilty khan himself added it to his coffee, so as not to lose dignity before his death. Diamond chips cut all the internal organs through which they passed: the esophagus, stomach, intestines - and the person died in terrible agony from internal bleeding.
That's not an invention!
The other day I read about the deaths of the greats at Zoshchenko's and there was a story of poisoning with diamond chips. The diamond dust particles are so hard and sharp that they cut the intestinal walls and cause internal bleeding, etc.
Banal logic tells me to draw a parallel between diamond dust and sand, since sand is even coarser than such dust. Have you ever eaten sand? I am. It crunches unpleasantly on the teeth. I died? I didn't even notice anything.
What is sand? These are dismissively small particles of quartz, glass, and solid rocks. If you eat them in chunks or even crushed small pieces, it is likely that there will be cuts in the esophagus and intestines and death is likely to occur. But the sand is finer, although it is crushed stones and glass into dust. He doesn't even cut his feet. It feels soft. Diamond dust is even finer. Do they die of sand? No. Do miners die from clouds of coal dust in mines? No. Why should you get diamond dust?
And in general, how could you get diamond dust in the ancient east? I still admit crushed diamonds, but you can't voluntarily drink them with coffee. This is nothing more than the author's invention of Pikul.
Not a single reliable source describing such an execution could be found. It seems that this is all V. Pikul's fantasy, described in the book "Favorite"
