message: Although some chalcedony contains some moganite, onyx and other chalcedonies are still chiefly cryptocrystalline quartz. That some moganite is present doesn't change that, and references still (and properly) tag onyx and other chalcedony materials as cryptocrystalline quartz. See Deer, William Alexander; Howie, R. A.; Wise W. S. 2004. Rock-Forming Minerals: Framework Silicates: Silica Minerals, Felspathoids, v. 4B, 2 ed. Bath, United Kingdom: The Geological Society Publishing House, pp. 62–64.  for an explanation of the differences between macrocrystalline quartz, and cryptocrystalline and microcrystalline (fibrous) quartz.  • Astynax talk 22:15, 7 April 2011 (UTC)

message: Sardonyx is the 11th stone on aaron's breastplate, which stands for the 11th tribe, or the tribe of Joseph. (Genesis 49; Exodus 28&39)  It is also the August Birthstone, which under the current sidereal astrology System, is ruled by Leo and the Sun.  Leo also governs the heart.  This is important because in the "Opening of the mouth Ceremony"(Which is not at all literal but rather spiritual), whenever the pharaoh opens his mouth, he reveals his heart.  
the "Sardonyx Seal" is important because it is an anagram for "Cylinder Seal".  It also says "Zion", "Coin", "Sword and Shield", and "Leonardo", "Nicholas", "Necklace", "Exodus", "Enoch", and "Heart of the cards", "Ark", "Noah" "Ankh", "Alexander", "Crown", "Six", "Kiss", "Sacred", "Achilles", "Chakra", "Ka", "Chi", "Qi", "Orion", "Aries" "Castle", "Corona", "Aura", "Jordan", "Dragon", "Yeshua", "Wonderland", "Alice", "Crows", "Eli", "Israel", "Learn", "Lion", "Kalki", "Conch", "Shell", "Zen", "Rose", "Zero", "One", "Rain", "Deer", "Creation", "Narnia", "Aslan", "Oz", "Circle", "Snake", "Scale", "Disk", "Code", "Riddle", "Lord", "Sons" and plenty more words.  
In Modern English Alchemy, this stone seal is more important than the emerald tablets.  This may not be true in other languages however as it may not translate.

message: The description of Onyx says,
:Onyx comes through Latin (of the same spelling), from the Greek ὄνυξ, meaning "claw" or "fingernail". With its fleshtone color, onyx can be said to resemble a fingernail. The English word "nail" is cognate with the Greek word.[2]
Yet there's not a single image of a flesh tone mineral. The major image is of Sardonyx and there is another image with several stones of black onyx. I did a search and the most jewelry web sites state that Onyx is black or "a black and white banded variety of Agate." So, this is a somewhat confusing state of affairs.

thread_title:  No image with basic color 

message: The image used on this article is also used on the Agate page, and given the descriptions on both pages seems as though it can't be an example of both simultaneously.  "Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands: agate has curved bands and onyx has parallel bands."
Agate page description "Banded agate (agate-like onyx); the specimen is 2.5 cm (1 inch) wide"
Onyx page description "A slice of sardonyx (width = 2.5 cm)"
Is this a mistake or not?NMLevesque (talk) 16:31, 23 January 2015 (UTC)
replies: text: The problem is that the term is not a mineralogical definition, but rather a very old, and imprecise gemological and common usage to describe a pattern in what is just microcrystalline quartz. Many famous onyx and sardonyx pieces do not have anything like strictly parallel bands. The onyx famous for use in intaglio and cameo hardstone carvings does have more or less parallel banding. Moreover, and although a few authorities argue differently, not all agate has banding (moss, plume and other types of patterns, plus those in which banding is isolated in a tiny fraction of a given stone). It would be best to find a better reliably sourced definition that is inclusive of those that lie outside the horizontally bedded onyx type.  • Astynax talk 19:04, 23 January 2015 (UTC)

message: The wiki page of Jahangir throne mentions that it is made of touchstone whereas here it is cited as an example of something made of black onyx. Are touchstones same as black onyx? 14.139.226.50 (talk) 06:45, 24 January 2023 (UTC)

text: Of note, the user who added it also added that the Throne was made from "black onyx, imported from Belgium", not exactly credible. --Auric talk 18:23, 12 May 2024 (UTC)

message: In the lead paragraph: "agate has curved bands while onyx has parallel bands."
Parallel does not mean "equidistant straight lines", it means "everywhere equidistant". But it would probably be best to just say "agate has curved bands while onyx has relatively straight ones." DCDuring (talk) 12:02, 13 July 2023 (UTC)
