Onyx is a banded variety of the oxide mineral chalcedony. 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. The colors of its bands range from white to almost every color (save some shades, such as purple or blue). Commonly, specimens of onyx contain bands of black and/or white.
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.
Onyx is formed of bands of chalcedony in alternating colors. It is cryptocrystalline, consisting of fine intergrowths of the silica minerals quartz and moganite. Its bands are parallel to one another, as opposed to the more chaotic banding that often occurs in agates.
Sardonyx is a variant in which the colored bands are sard (shades of red) rather than black. Black onyx is perhaps the most famous variety, but is not as common as onyx with colored bands. Artificial treatments have been used since ancient times to produce both the black color in "black onyx" and the reds and yellows in sardonyx. Most "black onyx" on the market is artificially colored.

USS Onyx (PYc-5), was a diesel coastal patrol yacht of the United States Navy during World War II.
The ship was built in 1924 as Janey III by Consolidated Shipbuilding Corp. of Morris Heights, New York, and was subsequently renamed Rene and Pegasus.
Purchased by the Navy on 3 December 1940 from Clifford C. Hemphill, of New York City, converted to Navy use and named Onyx, she was classified as a coastal yacht on 13 December 1940, and commissioned on 27 February 1941.
After conversion she departed New York for Norfolk, arriving on 22 March. Sailing again, she reached New Orleans on 5 April to report for duty to Commandant 8th Naval District. Onyx performed services for ComEight as a coastal patrol vessel around the Gulf area until January 1942. On 22 January she departed Key West, Florida to return to New York and arrived there on 31 January.
Onyx was again ordered to report to the 8th Naval District at New Orleans and was underway by 13 March, arriving on 27 March. She resumed services and continued in this capacity until February 1944 when she was extensively damaged in a collision. Beyond economic repair, her ordnance was removed and she was placed out of commission, in service, retaining her name and designation, on 15 May 1944. She was designated a target vessel on 31 May, the same year, and made available for disposition on 31 October.
Monolith is a box set made by avant-garde music composer Buckethead under the name of Death Cube K (an anagram of Buckethead), released in December 2007 through TDRS Music.
This box set contains five unmarked CD-Rs in unmarked digipaks, each one including only one unbroken track. Some listeners theorize the five discs are intended to be played simultaneously like Zaireeka by The Flaming Lips. The title Monolith as well as the result of combining the tracks have been cited as evidence for the theory by fans. Producer Travis Dickerson declined to solve the mystery.
Currently, this set is exclusively available on the TDRS website.
Each song is a separate disc.

Monoliths are machines built by an unseen extraterrestrial species that are described in Arthur C. Clarke's Space Odyssey series of novels and films. During the series, three monoliths are discovered in the solar system by humans and it is revealed that thousands, if not more, were created throughout the solar system, although none are seen. The subsequent response of the characters to their discovery drives the plot of the series. It also influences the fictional history of the series, particularly by encouraging humankind to progress with technological development and space travel.
The first monolith appears in the beginning of the story, set in prehistoric times. It is discovered by a group of hominids, and somehow triggers a considerable shift in evolution, starting with the ability to use tools and weaponry.
The extraterrestrial species that built the monoliths is never described in much detail, but some knowledge of its existence is given to Dave Bowman after he is transported by the stargate to the "cosmic zoo", as detailed in the novels 2001: A Space Odyssey and 2010: Odyssey Two. The existence of this species is only hypothesized by the rest of humanity, but it is obvious because the monolith was immediately identified as an artifact of non-human origin.
