Aquamarine and emerald green are from the same family, but they are surprisingly different. Aquamarine and green emerald are both beryllium aluminum silicates, but green emerald is found with trace amounts of chromium (and sometimes vanadium), while aquamarine gets its color from iron impurities in colorless beryl (goshnite)
Aquamarine and emerald green have the same gravity and refractive index, but emerald green tends to be opaque and opaque, while aquamarine, on the other hand, offers good clarity and clarity
Its name is derived from a Latin word meaning sea water, which refers to the color of this stone, which is very similar to the blue color of the ocean and the sea
Aquamarine stone is one of the clear and transparent stones and can be seen in blue and bluish-green colors

:Aquamarine, aquamarine identification
Aquamarine and other types of beryl stones with a hardness of 7.5 to 8 on the Mohs scale are quite durable and hard. Dark and deeply saturated blue is considered a desirable and valuable color in aquamarine. Other types of beryl are morganite, goshnite, golden beryl (heliodor), green beryl and bixbite
Aquamarine is often recognized by its unique sea blue color. This stone is very hard and has a glass luster. Aquamarine stones have better transparency than other similar gems
The color intensity and clarity of the stone are the most important criteria for evaluating aquamarine, and then the quality of the cut is the next step. Aquamarine is colored with a small amount of iron, and in the tests of compounds, the amounts of elements and the hexagonal crystal structure easily distinguish it from other blue-green stones
:Aquamarine The brightness and clarity of aquamarine
Some jewels have long bezels and hollow shafts, and a sign of the beryl family. The parallel marks of foreign minerals, which is considered one of the rare features, creates the phenomenon of a cat’s eye (shiny and polished) or a star (stellar) with six clear rays
These species are available in cut form. High quality cat’s eye aquamarines have very high prices. Six-ray species with a star or “stellar aquamarine” are extremely rare and very valuable. Aquamarine has a vitreous luster after cutting
:Sources and origin of aquamarine
With many mines throughout the country, Brazil can be considered the main producer of aquamarine. Other aquamarine deposits are located in Australia, Myanmar (Burma), China, India, Kenya, Madagascar, Mozambique, Namibia, Nigeria, Pakistan, Zambia, and Zimbabwe, as well as in several locations in the United States.

Weighing 26 kilograms, Dom Pedro was cut by German jewelry designer Bernd Munsteiner in 1992 in Idar Eberstein, Germany, and is the largest piece of aquamarine ever discovered
:Aquamarine color
Color intensity is one of the most important criteria in evaluating colored gemstones, but unlike other gemstones, aquamarines with lower color intensity will not be worth less because most emeralds are pastel blues and many people prefer lighter gemstones with clear crystals. They prefer stones with deep and bold colors
Aquamarine Cut and shape of aquamarine
Aquamarine is found in two cuts, cut and cut. Brills are especially suitable for rectangular or square cuts. The most popular aquamarine cut is the emerald green step cut. Diamond cuts with long or rectangular shapes are also very popular
Polished and messy cheeks are the same as cat-eye and star-shaped cheeks. Skilled jewelers are able to cut any possible shape with aquamarine. The most common types of cuts are traditional shapes such as round, pear, oval.
Fancy cuts are hard to find in larger sizes. Sometimes aquamarine and other types of beryl are cut into decorative shapes and carvings.
:Aquamarine processing
Aquamarine often does not require special processing, but sometimes heat is used to process the color. Heating at a low temperature will reduce unwanted green and yellow colors. Darker colors of aquamarine, such as lower quality stones, are often heated (usually at 725-850 F or 400-450 C) to produce a more appropriate blue color. Heating at a higher temperature causes discoloration
Aquamarine-like species
Aquamarine belongs to the beryl group of minerals. There are a few varieties of gem-quality beryl, most of which are classified by color and color factors, such as emerald green. Ak
Aquamarine is also found with polish (cat’s eye and star aquamarine), which are very rare and valuable. Other gemstones that are similar to aquamarine are Larimar, Amazonite, Tourmaline, Sapphire and Lal Badakhshan
Aquamarine is the most popular gemstone and associated brand names
Green emerald, precious beryl, golden beryl, cat’s eye aquamarine and morganite are among the most famous related gemstones
:Gemstones and lesser known brand names
Red beryl or bixie bit, heliodor, green beryl and goshenite (colorless beryl) are among lesser known gemstones
Aquamarine care and washing of gemstones and aquamarine jewelry
Aquamarine is one of the most durable gemstones, but still requires careful maintenance and care. Avoid wearing aquamarine jewelry when working with strong chemicals. To prevent scratches, always store aquamarine gemstones separately from other types of gemstone jewelry
