As shown in Fig. 5, the mechano-bactericidal performance of acicular aragonite was dependent on the size of the nanoneedles. This result is shown in Table 1. This needle-size dependence of mechano ...
Aragonite is a carbonate mineral, one of the three most common naturally occurring crystal forms of calcium carbonate, CaCO3. It is formed by biological and physical processes, including precipitation from marine and freshwater environments. This specimens comes from Mexico and is approximately 5" * 3.5" * 2.75".

White Aragonite, also known as Cave Calcite from the Potosi Mine of the Santa Eulalia District in Chihuahua, Mexico. This stalactitic variety of Aragonite crystal is known as Flos Ferri, meaning "flowers of iron". It grows similar to the finger-like formations of ocean coral. Interestingly, Aragonite is a calcium carbo
Aragonite occurs worldwide, but the most popular specimens are the reddish-brown pseudohexagonal crystals from Spain and Morocco, as well as the delicate white "flowers of iron" which are found in the Magdelena district of Socorro, New Mexico. The only Aragonite of gem quality used for faceted stones have been found in Horenec, in the Czech ...
Aragonite from Mexico. LED lighting vs short wave
Layered aragonite can recently form inside the pipes at hot springs. Photo: Lysippos. If the aragonite incorporates organic debris (such as moss, twigs or leaves) at the site, it may be called tufa. Often, these deposits will develop banding, and will be marketed under such names as Onyx Marble, Suisan Marble, California Onyx, or Mexican Onyx.
We collected discreet water samples at a range of depths in the Gulf of Mexico, including eight Lophelia reefs, and measured total alkalinity and pH to calculate the aragonite saturation state (Ω arag). The deep waters of the Gulf of Mexico (> 300 m depth) were at aragonite saturation states between 0.98 and 1.69.
Giant Crystal Columns Crowd a Cave in Mexico. The interior of the Cave of the Crystals (La Cueva de los Cristales) in Naica, Mexico. It was discovered during operations at a nearby silver mine. The crystals run to several meters in length and people could only explore the cave for short periods of time.

Unit cell volumes of aragonite as a function of environmental variables for (A) Gulf of Mexico L. pertusa live septa samples (violet circles) versus surrounding seawater chemistry at colony collection sites, and (B) synthetic aragonites precipitated from seawater versus seawater formation chemistry (triangles, black dashed trend line).
The frequent occurrence of slight amounts of Strontium in aragonite was known during the time of Becquerel and he ascribed the luminescence to the presence of strontium. Later, Nichols confirmed the idea. Hence the name strontioaragonite for some specimen of very bright red fluorescing aragonite. Actually, strontium is not considered anymore as ...
Aragonite Group. The Ca analogue of strontianite. The principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calcite).It is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions.

Aragonite is less common than calcite, but in the organic world it is very common and very important because it is an integral part of most seashells, pearls, and ancient fossils, especially ancient ammonites. Common, But Complex. Aragonite and calcite form under low-temperature conditions, but Aragonite is a little less stable.
Aragonite cave coral Chihuahua Mexico 3.28inch 8cm
This is a large (25cm x 15cm x 15 xm) coralloid formation of Aragonite from Santa Eulalia, Chihuahua, Mexico. I don't know if coralloid is an official term, but this specimen looks enough like coral that many people assume it is coral. At the extremities it is covered by tiny crystals. The whole specimen glows an intense green and lit up brightly even in a well lit room.
Aragonite is a good Earth healer and an excellent grounding stone. It works with all of the chakras, but specifically with the Root/Base Chakra, for grounding the spirit and creating a deeper connection to planet Earth.
Aragonite (IMA symbol: Arg) is a carbonate mineral, one of the three most common naturally occurring crystal forms of calcium carbonate, Ca C O 3 (the other forms being the minerals calcite and vaterite).It is formed by biological and physical processes, including precipitation from marine and freshwater environments. The crystal lattice of aragonite differs from that of calcite, …
