While the chemicals used to grow crystals are inexpensive, the ones added to make them glow in the dark are not. Worse, they don’t play well with water. What do you dissolve the crystal powder in to grow the crystals? You guessed it — water! According to Armenian "The Queen of the Serpents" legend, the serpents of Mount Ararat select a queen who destroys invading armies of foreign serpents, and carries in her mouth a "wonderful stone, the Hul, or stone of light, which upon certain nights she tosses in the air, when it shines as the sun. Happy the man who shall catch the stone ere it falls." ( von Haxthausen 1854: 355). These are sugar crystals that glow in the dark. I colored the crystals using food coloring. These are non-toxic!

A later elaboration of animal-gratitude stories involves grateful animals and ungrateful people, who are typically rescued from a pitfall trap (Ashliman 2010). Two versions mention marvelous gems. The English historian Matthew Paris's c. 1195 Chronicles says that Richard I of England (1157-1199) used to tell a parable about ungrateful people. A Venetian, Vitalis, was rescued from a horrible death by a ladder being let down into a pit into which he had fallen. A lion and a serpent trapped in the same pit used his ladder to escape, and the lion in gratitude brought to Vitalis a goat he had killed and the snake a luminous jewel that he carried in his mouth. As Richard reportedly told the story after his return from the Crusades he may have heard it in the East, as similar stories, but without the stone being luminous, occur in two Indian collections, the c. 300 BCE Kalila wa Dimnah and the 11th-century Kathasaritsagara (Ball 1938: 505). The English poet John Gower's 1390 Confessio Amantis tells the story of the rich Roman lord Adrian and the poor woodcutter Bardus. Adrian falls into a pit that had already captured an ape and a serpent, and promises to give half his wealth to Bardus for pulling him out. After Bardus rescues the three, out of gratitude the ape piled up firewood for him and the serpent gave him "a stone more bright than cristall out of his mouth", but Adrian refuses to pay his debt. Bardus sells the luminous gem for gold and afterwards found it again in his purse, and the same thing happened every time he sold it. Emperor Justinian I summons Bardus, listens to his testimony supported by the magically reappearing gem, and compels Adrian to fulfill his promise (tr. Clouston 1887 1: 224–226).

If you think regular crystals are boring, try growing glow in the dark crystals. These magical creations are easy to make, but you need to apply a bit of science to get them to work. Why Glow in the Dark Crystal Kits Don’t WorkThis quartz crystal glows in the dark. It’s easy to replicate the technique to make your own crystals and gems glow. The 3rd-century CE Life of Apollonius of Tyana, the Greek sophist Philostratus's biography of Apollonius of Tyana (c. 3 BCE-97 CE), says that in India, people will kill a mountain dragon and cut off its head, in which, "are stones of rich lustre, emitting every-coloured rays and of occult virtue." It also mentions a myth that cranes will not build their nests until they have affixed a "light-stone" (Ancient Greek lychnidis, "shining") to help the eggs hatch and to drive away snakes (tr. Conybeare 1912: 103, 155).

If all of this sounds like too much work or you have a pretty crystal you’d like to make glow, you can simply paint the base of the crystal with phosphorescent paint, glue, etc. This works best with a clear or at least translucent crystal. You don’t have to paint the entire surface because the light will travel outward to illuminate the crystal. How Long Do the Crystals Glow?Boil enough water to fill the container so that it covers the glowing base. The more liquid you have over the base, the more room the crystals have to grow. They won’t grow out of the liquid, so plan accordingly. Jordanus, Friar, tr. Henry Yule (1863), Mirabilia Descripta: The Wonders of the East, Hakluyt Society.

In the 1st century BCE, the Greek historians Diodorus Siculus (c. 90–30) and Strabo (c. 63–24) both record the peridot (gem-quality olivine) mine of Egyptian king Ptolemy II Philadelphus (r. 285–246 BCE) on the barren, forbidden island of Ophiodes ( Ὀφιώδης νήσος, "Snakey") or Topazios ( Τοπάζιος, "Topaz"), modern Zabargad Island, off the ancient Red Sea port Berenice Troglodytica. Hawkes, David (1985), The Songs of the South: An Anthology of Ancient Chinese Poems by Qu Yuan and Other Poets, Penguin Books. Some fluorite, particularly the variety chlorophane (aka pyroemerald and cobra stone), may become very faintly luminescent simply from the heat of one's hand. Chlorophane is unusual for combining the properties of thermoluminescence, triboluminescence, phosphorescence, and fluorescence; it will emit visible spectrum light when rubbed, or exposed to light or heat, and can continue emitting for a long period of time. Among the gravels of the Irtysh River, near Krasnoyarsk, Russia, the German mineralogist Gustav Rose recorded seeing chlorophane pebbles that shone with brilliancy all night long, merely from exposure to the sun's heat. For luminous gem myths, Ball concludes that while it is "not impossible that the inventors of certain of the [luminous gem] tales may have been acquainted with the luminosity of gems, in my opinion many of the tales must be of other origin" (1938: 497). If you’re pleased with the glow, you can continue to the next step, which is sealing the stone. Otherwise, you may wish to apply another 1-2 coats of paint.Mineralogical luminosity [ edit ] Thermoluminescence from heating chlorophane specimens on a hotplate. Triboluminescence from rubbing together two quartz crystals. Harvey, E. Newton (1957), A History of Luminescence from the Earliest Time until 1900, American Philosophical Society Memoirs, 44.

The OED defines pyrope (from Greek Πυρωπός, lit. "fire-eyed")" as: "In early use applied vaguely to a red or fiery gem, as ruby or carbuncle; (mineralogy) the Bohemian garnet or fire-garnet"; and carbuncle or carbuncle-stone (from Latin "carbunculus," "small glowing ember") as: "A name variously applied to precious stones of a red or fiery colour; the carbuncles of the ancients (of which Pliny describes twelve varieties) were probably sapphires, spinels or rubies, and garnets; in the Middle Ages and later, besides being a name for the ruby, the term was esp. applied to a mythical gem said to emit a light in the dark." (Ball 1938: 498). Laufer cites three c. 4th-century Chinese grateful-animal stories that parallel Heraclea's stork. The Shiyi ji ("Researches into Lost Records"), compiled by the Daoist scholar Wang Jia (d. 390 CE) from early apocryphal versions of Chinese history, recounts an anecdote about King Zhao of Yan (燕昭王, r. 311–279 BCE) and grateful birds with dongguangzhu (洞光珠, "cave shining pearls"). Sydney H. Ball recounts the widespread variation of the animal-gratitude snake story involving a wild animal (often called carbuncle, Spanish carbunclo, or Latin carbunculo) with a luminous gem on its head, and which Europeans apparently introduced into Africa and America. The size of the particles also matters. Bigger glowing particles hold a charge better than finely ground pigment. So, before you go to all the trouble of coating a plastic glowing star or a glowing glass marble, make sure you’re happy with the color, brightness, and longevity of the glow.
