Bibliography

As you gather the sources for your Wikipedia contribution, think about the following:

Is the source from a reliable publication?
- Reliable publications include established newspapers, academic journals and books, textbooks, and other published sources with reputations for accuracy and fact-checking.
- Unreliable sources include blog posts and other self-published works, press releases, and social media posts.
Is the source verifiable?
- In order for a source to be considered verifiable, other editors should be able to consult the source.
Is the source independent of the subject?
- Is the source connected in any way to the subject? This is especially important when writing biographies or about organizations.
- For example, if you were writing a biography, sources like the person's webpage or personal blog would not be considered independent.
Is the source primary or secondary?
- Primary sources include first-hand accounts, autobiographies, and other original content.
- Wikipedia allows limited use of primary sources, but typically only for straightforward, descriptive statements of facts, and only if they are published and verifiable without requiring specialized knowledge.
- Secondary sources should be the main basis for a biography on Wikipedia.
If you're working on a topic related to medicine or psychology, ensure that your sources follow these special guidelines.
If you're creating a new article, consider the following:
- Ensure that your topic meets Wikipedia's notability guidelines.
- In order for a topic to meet the notability requirement, you must be able to identify 2-3 sources that are reliable, verifiable, and independent of the subject you're writing about.
- Finding sufficient sources to establish notability can be especially hard when writing about people or organizations.
- Sources that are not independent of the subject might be useful additions, but don't count towards the notability requirement.
- Wikipedia has developed special guidelines for writing about living persons. Please follow these carefully.
- Wikipedia has a series of guidelines for writing about different categories of people, such as academics and artists. If you're trying to create a new entry about a living person, please look at these carefully.

If you're not sure whether a source is reliable, ask a librarian! If you have questions about Wikipedia's sourcing rules, you can use the Get Help button below to contact your Wikipedia Expert.

Bibliography

Mat, Mahmut -> Good supporting information on Aquamarine's chemical composition.
Good supporting information on hardness scale.
Good Additional evidence (Inclusion content, accessibility, refractive index, iron, physical appearance culture facts)
New information to add: Largest Aquamarine found.

Examples:

Luke, Learie. 2007. Identity and secession in the Caribbean: Tobago versus Trinidad, 1889–1980 Kingston, Jamaica: University of the West Indies Press.
- This is a book published by a university press, so it should be a reliable source. It also covers the topic in some depth, so it's helpful in establishing notability.
Galeano, Gloria; Bernal, Rodrigo (2013-11-08). "Sabinaria , a new genus of palms (Cryosophileae, Coryphoideae, Arecaceae) from the Colombia-Panama border". Phytotaxa.
- This is a peer-reviewed scientific journal, so it should be a reliable source. It covers the topic in some depth, so it's helpful in establishing notability.
Baker, William J.; Dransfield, John (2016). "Beyond Genera Palmarum: progress and prospects in palm systematics". Botanical Journal of the Linnean Society.
- This is a peer-reviewed scientific journal, so it should be a reliable source for a specific fact. Since it only dedicates a few sentences to the topic, it can't be used to establish notability.

Aquamarine is a pale-blue to light-green variety of the beryl family. [Citation is included] The color of aquamarine can be changed by heat, with a goal to enhance its physical appearance (though this practice is frowned upon by collectors and jewelers). [Citation is included]

Aquamarine has a chemical composition of Be3Al2Si6O18 [Citation is included] [https://geologyscience.com/gemstone/aquamarine/?amp], also containing Fe²⁺. [Citation is included] It has a hardness of 7.5–8 on the Mohs scale. [Citation is included] https://www.gemsociety.org/article/select-gems-ordered-mohs-hardness/. While aquamarine often contains no inclusions, it may possess ~~can~~ ~~have~~ them, ~~noticeable or not,~~ with ~~composed of~~ content such as mica, hematite, saltwater, [Citation is included] biotite, rutile or pyrite. ^[3] (p.124)

Aquamarine is a fairly common gemstone, [Citation is included] rendering it more accessible for purchase, compared to other gems in the beryl family. ^[4] p.124 However, there is a rarer deep blue variant called maxixe, but its color can fade due to sunlight. The color of maxixe is caused by NO₃. Dark-blue maxixe color can be produced in green, pink or yellow beryl by irradiating it with high-energy radiation (gamma rays, neutrons or even X-rays).

Add in table "refractive index": 1.57-1.59. ^[5]

Article Body

The name aquamarine comes from aqua, (Latin for 'water'), and marine, deriving from marina, Latin for 'of the sea'. [Citation is included] The word aquamarine was first used in the year 1677. [Citation is included]

The word aquamarine has been used as a modifier for other minerals like aquamarine tourmaline, aquamarine emerald, aquamarine chrysolite, aquamarine sapphire, or aquamarine topaz. [Citation is included]

The value of aquamarine is determined by its weight, colour, [Citation provided] cut, and clarity. [Citation provided] Due to its relative abundance, aquamarine is comparatively less expensive than other gemstones within the beryl group, such as emerald or bixbite (red beryl), however it is typically more expensive than similarly coloured gemstones such as blue topaz. [2 Citations provided] Naturally occurring blue hued aquamarine specimens are more expensive than those that have undergone heat treatment to reduce yellow tones caused by ferric iron. [Citation provided] p.125 ^[6] Cut aquamarines that are over 25 carats will have a lower price per carat than smaller ones of the same quality. [Citation Provided]

Aquamarine is the birth stone for the month of March. [Citation Provided] It has historically been used as a symbol for youth and happiness, due to its color, which has also, along with its name, made Western culture connect it with the ocean. [2 citations provided] Ancient tales have claimed that aquamarine came from the treasure chests of mermaids; which led to sailors using this gemstone as a lucky charm to protect against shipwreck. Additionally, ancient Romans believed this stone had healing properties, due to the stone being almost invisible when submerged in water. [Citation provided] ^[7] p.124 ~~Ancient Romans believed that aquamarine could protect people who are travelling across the sea; they also used aquamarine to prevent illnesses.~~

The Chinese used it to make seals, and showpiece dolls, ^[8] ~~figurines, and engravings^{[citation needed].}~~ The Japanese used it to make netsuke. [Citation provided]

Aquamarine became a state gem for Colorado in 1971. [Citation provided]

Aquamarine can be found in countries like Afghanistan, China, Kenya, Pakistan, Russia, Mozambique, the United States, [Citation provided] Brazil, Nigeria, Madagascar, Zambia, Tanzania, Sri Lanka,[Citation provided] Malawi, India, Zimbabwe, Australia, Myanmar, and Namibia. [Citation provided] The state of Minas Gerais is a major source for aquamarine. [Citation provided]

Aquamarine can mostly be found in granite pegmatites. [Citation provided] It can also be found in veins of metamorphic rocks that became mineralized by hydrothermal activity. [Citation provided]

The World's largest aquamarine ever found is the Dom Pedro Aquamarine found in Pedra Azul, Minas Gerais, Brazil, in the late 1980's. It is roughly 4.6 pounds, cut from a 100-pound aquamarine crystal. It is 10,363 carats and resides in the Smithsonian's National Museum of Natural History, in Washington. ^[9]

Now that you have compiled a bibliography, it's time to plan out how you'll improve your assigned article.

In this section, write up a concise outline of how the sources you've identified will add relevant information to your chosen article. Be sure to discuss what content gap your additions tackle and how these additions will improve the article's quality.

Consider other changes you'll make to the article, including possible deletions of irrelevant, outdated, or incorrect information, restructuring of the article to improve its readability or any other change you plan on making. This is your chance to really think about how your proposed additions will improve your chosen article and to vet your sources even further.

Note: This is not a draft. This is an outline/plan where you can think about how the sources you've identified will fill in a content gap.
