| 1413 | Jamison bogwood agate, misspelling?, see Jamieson Bogwood Agate. |
| 1414 | Janos Agate Nodules, for Janos, Sonora, Mexico, red, yellow, gray, thunder egg agates named for either Rio Janos or the Village of Janos in northwestern Chihuahua, Mexico. These are sometimes marketed under the trade names "Hi-Fi" or "High Fidelity" agate (Brad Cross, pers. comm., Sept. 23, 1995). Cross (1996, p. 80, 81) suggested these are thunder egg agates and suggested that field observations suggested these were syngenetic products of crystallizing magma but did not say what this evidence is. |
| 1415 | Jardin, Mexico, color illustration, adv., Harry Sering Co., Lapidary Journal, v. 32, no. 3, p. 678-679. |
| 1416 | Jasp agate, also speckled jasp-agate, jaspagate, and Jaspachate (German). It was defined by Schaller, (1917, p. 56) as "intermediate between between jasper and chalcedony with predominant opaque jasper." The term is widely used by American rockhounds in preference to the other variants. Most authors make it equivalent to the older agate jaspers (see also). A useful term when used with common sense. It is often and effectively used in conjunction with locality designation as an adjectival modifier. The French term jaspe fleuri (which see) is generally equivalent. |
| 1417 | Jasp-agate Hill, San Bernardino County, California, site that produced moss, plume and jasp-agates recorded by Berkholz (1971, p. 38). The name Jasp-Agate Hill does not appear in Geographic Names Information System. The site was recorded to be near Rainbow Basin which is at 350146N and 1170209W, Mud Hills Map, USGS 7.5 minute map, San Bernardino County, California. |

| 1420 | Jasper-agate, descriptive, sometimes used as a synonym of jasp-agate. Kraus and Slawson (1947, p. 227) used the term to appy to lighter colored agates with irregular inclusions of jasper. This usage varies from jasp-agate inasmuch as it makes the jasper a lesser part of the agate whereas jasp-agate usually implies jasper with small amounts of agate. |
| 1421 | Jasper Bar, see jaspillite. |
| 1422 | Jasper conglomerate. Zeitner (1964,p.983) called it a jasper in which rounded pebbles are cemented together with a secondary, silicic cement. Color illustration in Zeitner (1978, p. 2100-2110). |

S. Geological Survey, 7.5 minute series (Topographic). See Chandler (1935, p. 69). Berkholz (1971, p. 54-56) used the name Jasper Hill for a site in the Cady Mountains, San Bernardino, County, California. The name Jasper Hill, however, does not appear in Geographic Names Information System in spite of its early usage. |
| 1425 | Jasper Hill, Kern County? California, a name used by Berkholz (1962, locality 8,1971, p. 22) for a site that produced reworked ribbon jasper, moss jasper and plume and jasp agates. The name Jasper Hill does not appear in Geographic Names Information system. |

| 1428 | Jasper Jade, jade substitute that may be serpentine, quartz, jasper, or any mineral that has the colors of jade. Shipley (1971, p. 105) suggested the term was used by Chinese dealers and that it was sometimes called ASoochow Jade.@ The term is still seen used in markets where where high trade standards do not exist. |

| 1437 | Jaspillite, misspelling of jaspilite above. Fraser and Fraser (1989, p. 85) suggested it was intorduceed in a recent British Gemological work, but Zeitner (1964, p. 982) listed jaspillite as an alternate spelling of jaspilite.

Geographic Names Information System records Jornada del Muerto as 34' 00" N and 106o 47' 00" W, Socorro County, New Mexico, but Rio Grande Gem material suggests Jornada Draw as the site from which they found their material. |

About the Agate Lexicon
The Agate Lexicon and glossary of amorphous and cryptocrystalline silica gems have been designed to be used in conjunction with the Agate Bibliography, which was compiled to be used by researchers, hobbyists, historians, lapidaries and other individuals which have an interest in these stones. Numerous localities are listed here but this does not imply that the sites are available for collectors or collecting. Many of the sites are historic, depleted, are on private property or are protected by legal leases or claims and some are now on protected sites such as parks, nature preserves, or historic areas. Wherever possible, stratigraphic details are listed, but the user must always refer back to the original citations. Map information has been derived from 7.5' x 7.5' topographic maps issued by the U.S. Geological Survey (USGS) and latitude and longitude have been derived mostly from Geographic Names Information System of the USGS.
Authors should not cite the Agate Bibliography or Agate Lexicon as a source in their published or unpublished works but should cite only those publications listed therein.
Named varieties of agates, jaspers, etc., have created special problems for both scientific researchers and historians. We have recognized at least two different usages of names. Some names appear to have geologic / historic validity, as they were described along with the lithology / geography of a region. Some names were introduced simply as trade names to boost sales of gem dealers. In the former case, the name will be followed by appropriate literary citation as to who first used the name and in what context. In the latter case, an advertisement (abbreviated adv.) is the first published record or public notice. We have tried to find the earliest citation in either case and the user should keep in mind that older citations unknown to us may exist. Advertisements are not cited to generate business but to simply give a historic source; many of the firms appearing in the citations are indeed no longer in existence.
Cited materials are generally only from accessible sources such as professional journals, magazines, hobbyist journals, open file reports of government agencies, newspapers, etc. Bulletins issued by local clubs and societies are generally not cited with the exception of those special publications that were actually made for public distribution.
Wherever possible, imagery of one or more specimens of named agate varieties, structures, patterns, etc. are provided. Images have been provided by several sources and are not to be utilized in other pages without the consent of the image owner.
