Aquamarine
The blue to blue-green variety of beryl. Its GB/T basic name is "Aquamarine", and heat treatment to reduce green tones is common. This page compares how the major standards and institutions name it, what must be disclosed when selling it, whether it can be worn every day, how it is treated and identified, and which source each conclusion comes from.
Price, rarity and origin are outside the scope of this wiki.
Questions people ask about Aquamarine
Every sentence below is followed by the registered fact it rests on; answers add no new facts and promise no outcome.
Q1How can you tell if an aquamarine is real?
Colour alone cannot tell natural aquamarine from synthetic or treated beryl; a gemmologist relies on growth features and inclusions seen under the microscope and on trace elements detected by EDXRF.G&G Winter 2016Synthetic aquamarine is commercially available.CIBJO Gemstone Book 2022Whether one particular bead is natural, treated or synthetic — only a laboratory report can settle that.What this page can answer
Q2Is aquamarine usually heat-treated?
Heating can turn iron-coloured blue-green or yellow beryl blue; the resulting colour is stable and hard to detect.GB/T 16553—2017Aquamarine heated to remove a yellow component for a pure blue needs only normal care.AGTA Gemstone Information Manual, 17th ed.Fracture filling also occurs; under magnification the exposed filler has a different surface lustre from the stone and may show a flash effect and gas bubbles.GB/T 16553—2017
Q3Does aquamarine lose its colour in sunlight?
Aquamarine's colour is described as stable in light.GIA Gem Encyclopedia (care guide)For display, case heat, sunlight and artificial light are all rated relatively safe.Gems & Gemology 1987 (Martin)The exception noted under the parent entry Beryl is Maxixe-type beryl, irradiated to a dark blue, which fades in light.Gems & Gemology 1987 (Martin) (via parent entry Beryl)
Q4Is aquamarine durable enough for an everyday ring?
At Mohs 7.5 to 8 it is a durable jewellery stone, as long as it is protected from scratches and hard knocks.GIA Gem Encyclopedia (care guide)Large stones in rings, which take knocks easily, need care; on square shapes, prongs on the corners protect the points from chipping.CIBJO Retailers' Reference Guide (2021)
Q5How do you clean aquamarine safely?
Warm soapy water is always safe; ultrasonic and steam cleaning are usually fine unless the stone has liquid inclusions or fractures.GIA Gem Encyclopedia (care guide)The occasional fracture-filled stone should be cleaned only with warm soapy water.GIA Gem Encyclopedia (care guide)Heat exposure is not advised.GIA Gem Encyclopedia (care guide)Hydrofluoric acid can attack it.GIA Gem Encyclopedia (care guide)
Q6What makes aquamarine blue?
Its blue to blue-green colour comes from trace elements in beryl.G&G Summer 2025Its composition is recorded as Be3Al2Si6O18 with elements such as iron.GB/T 16553—2017
Q7Where does aquamarine form?
Aquamarine forms mainly in granitic pegmatites, where elements such as beryllium become concentrated in the last fluid left as the magma crystallizes.G&G Summer 2025Gem-quality crystals grow most often in open pockets in the core of the pegmatite, and beryl crystals can reach metre-scale sizes.G&G Summer 2025
Q8What does aquamarine symbolize, and does it have healing powers?
There is no scientific evidence that aquamarine has healing powers: the UK advertising regulators ASA and CAP state that they have not seen evidence that crystal therapy can treat medical conditions.ASA/CAP guidance (UK)Its recorded cultural role is as a March birthstone: Jewelers of America and Japan's JJA list it for March, and the U.K. National Association of Jewellers lists it as traditional for March.Cultural records
Q9What makes good-quality aquamarine?
The most favoured aquamarine colour is a dark blue to slightly greenish blue of moderately strong intensity, and in general the purer and more intense the blue, the more highly the stone is rated; most faceted aquamarines are eye-clean.GIA Aquamarine Quality Factors

Material research: formation, causes and history
What authoritative sources say about how this material forms, what causes its colour and optical effects, where its name comes from and how people have used it. Each statement carries an evidence grade and its sources; it describes the material in general, not any specific piece.
How it forms
Aquamarine is the blue to blue-green gem variety of beryl, and its most important formation environment is the same as that of beryl: granitic pegmatite. Pegmatites form from residual water- and volatile-rich fluid at the final stage of granitic magma crystallization, during which incompatible elements such as beryllium are enriched and made available for beryl to crystallize. Gem beryl crystals commonly grow in open pockets in the core and central zones, including miarolitic pegmatites, and individual crystals can reach very large sizes.
Scope: Covers the predominantly granitic-pegmatite origin of natural gem-quality beryl (aquamarine); does not cover beryl of other origins or treated material.
Sources G&G Summer 2025
Where it forms
Granitic pegmatites, including miarolitic pegmatite dikes intruded at shallow crustal depths
Sources G&G Summer 2025
Residual water- and volatile-rich fluid at the final stage of crystallization, enriched in incompatible elements such as beryllium
Sources G&G Summer 2025
How it forms, step by step
A water- and volatile-rich residual fluid separates during the final stage of granitic magma crystallization
The residual fluid crystallizes while cooling from the outside inward, gradually enriching incompatible elements such as beryllium
Gem beryl crystals grow in open pockets in the core and central zones (including miarolitic cavities), with individual crystals reaching very large sizes
Link to appearance
The blue to blue-green colour of aquamarine is caused by trace elements in beryl; free growth in open pockets also favours clean, transparent gem-quality material.
Sources G&G Summer 2025
Timescale
The cited authoritative texts do not state a specific growth duration or absolute age for aquamarine/beryl crystals.

- Beryl (beryl group): Parent mineral species: aquamarine is the blue to blue-green variety of beryl
Supporting findings
During pegmatite formation incompatible elements such as beryllium are enriched in the residual fluid, supplying the components needed for beryl (including aquamarine) to crystallize.
Evidence grade AScope: The source lists beryllium among the enriched elements; it does not discuss the aquamarine variety specifically, so this cites the beryl-group mechanism generally.
Gem beryl crystals can grow in open pockets of miarolitic pegmatite dikes and can reach considerable size.
Evidence grade BScope: The source cites a single aquamarine crystal from the Skardu District of Pakistan; a single-locality example should not be generalised worldwide.
Gem-quality pegmatite crystals occur most often in open pockets in the core and central zones, and beryl crystals can reach metre-scale sizes.
Evidence grade AScope: The large sizes are reported maxima for several pegmatite minerals (including beryl), not a typical crystal size.

Human use and museum objects
Collection evidence shows that objects directly labelled aquamarine are all 19th-20th century necklaces (Met 48.187.509-48.187.512); the earlier material in the same evidence is beryl parent material from Egyptian lumps of ca. 1802-1450 B.C. and an 8th-7th century BCE beryl-set ring (Met 11.151.643a-l, 74.51.4136). Aquamarine belongs to the beryl parent material and does not constitute an independent material history.
Evidence grade AScope: Applies to collection objects labelled aquamarine, whose mineral identity is beryl (blue variety); aquamarine is not treated as a material independent of beryl.

Aquamarine is the blue (to blue-green) variety of beryl, not an independent mineral; among the collection evidence cited here, the ancient objects are recorded under the beryl parent material. The Metropolitan Museum holds only four objects labelled aquamarine - all 19th-20th century necklaces (48.187.509, 48.187.510, 48.187.511, 48.187.512), which are modern jewellery. The earlier objects in the same evidence belong to beryl: raw beryl lumps from late Middle Kingdom to early New Kingdom Egypt (11.151.643a-l, ca. 1802-1450 B.C.), an 8th-7th century BCE beryl-set ring (74.51.4136), and a Roman necklace with pearls and beryl beads (25.192.1, 1st-2nd century CE). These earlier instances must be attributed to the beryl parent material and cannot be written as a history of aquamarine as an independent material.

How it is identified
Aquamarine is a beryl, and colour alone cannot tell natural from synthetic or treated beryl. As with emerald, a microscope shows growth features and inclusions that distinguish natural, flux- or hydrothermally grown and clarity-enhanced material, while EDXRF detects the trace elements and flux or crucible residues that separate synthesis. Judging any of this needs a trained gemmologist and instruments, and the verdict should come from a qualified gem laboratory.
Evidence grade AScope: Applies to the beryl group; separating natural, synthetic and treated material requires microscopic and chemical testing at a qualified gem laboratory, and is not a self-identification method.
Aquamarine, the blue beryl, is often priced on locality, with goods traded under names such as Brazil, Madagascar or Pakistan. A locality name, however, is only a trade attribution and is not a determined origin. Origin work is a laboratory exercise: the deposit type is addressed first, then inclusion suites and trace-element suites (measured by methods such as laser ablation ICP-MS) are compared with reference databases for known localities to yield a conclusion of consistency or inconsistency with a source. Because the characteristic ranges of different localities overlap and vary within a single deposit, the conclusion is probabilistic and may be only inconclusive; heating, filling and diffusion alter the measurable features and must be excluded first. Origin cannot be inferred from appearance or name; an origin conclusion must be issued by a qualified laboratory for a specific specimen. This entry offers no self-test criteria or thresholds.

Other research findings
Aquamarine is a gem variety of beryl, and beryl is one of the significant gem minerals of granitic pegmatites.
Evidence grade AScope: The source uses the general term 'beryl' and does not single out the aquamarine variety; treating aquamarine as the blue to blue-green beryl variety follows trade nomenclature.
The largest faceted aquamarine (blue beryl) recorded by the 1988 GIA article Faceting Large Gemstones is a 2,594 ct stone in a private collection. This figure comes from 1988 literature and may since have been overtaken.
Evidence grade AScope: A record statement subject to change; the figure comes from 1988 literature and may since have been superseded. Concerns the aquamarine variety, not the beryl species record.
Sources G&G Spring 1988
The most favoured aquamarine colour is a dark blue to slightly greenish blue of moderately strong intensity; in general, the purer and more intense the blue, the more highly the stone is rated. Most faceted aquamarines are eye-clean.

Common care questions and matching entries
CleaningCleaning Aquamarine: stones treated by oil filling or resin filling of fissures must not be cleaned ultrasonically; for untreated stones, use caution with ultrasonic and steam cleaning, taking extra care when liquid inclusions or feathers are present; GIA material states that warm soapy water is always safe and that ultrasonic and steam cleaning are usually safe too, except for stones with liquid inclusions or fractures; stones are occasionally fracture-filled, and these should be cleaned only with warm soapy water. Chemicals: dyeing, oiling, resin impregnation, waxing and plastic impregnation are not permanent, and stones treated by oil filling or resin filling of fissures should be kept away from all solvents (including all detergents), chemicals and high heat; another entry states that Aquamarine is attacked by hydrofluoric acid. Heat and light: the entry says it should not be exposed to heat; the colour is stable to light; for untreated Aquamarine, display-case heat, daylight and artificial light are relatively safe. Wear: GIA material gives a Mohs hardness of 7.5–8, making it a durable jewellery gem, but it should be protected from scratches and hard knocks; stones treated by oil filling or resin filling of fissures are prone to breaking and should be worn with care. Whether each entry fully answers a specific care question goes by the entry wording.

Whether a treatment has to show in the name differs between the two rule sets (this site’s paraphrase):
- GB/T 16552—2017: a method classed as treatment has to be stated in the name itself — the method put before the name, or added in brackets after it; a method classed as optimization does not need to appear in the name, though one marked “Optimization (annotation required)” still has to be noted in the quality documents.

- CIBJO Gemstone Book 2022: no longer splits treatments into ones that need specific disclosure and ones that need only general disclosure: every treatment is to be disclosed, and the seller tells the buyer which treatment was used and what special care it calls for.

What it is and how it's identified
The material facts table for Aquamarine records: composition beryl (Be3Al2Si6O18, containing Fe and other elements), crystalline and hexagonal, with a hexagonal prismatic crystal habit and commonly longitudinal striations on the crystal faces; Mohs hardness 7.5–8, with one direction of imperfect cleavage; density 2.67–2.9 g/cm³ (clause value 2.72, tolerance +0.18/−0.05, from which the range is derived); refractive index 1.56–1.6 (clause value 1.577–1.583, tolerance ±0.017, from which the range is derived); birefringence 0.005–0.009, with an optic character that is anisotropic, uniaxial negative; and a vitreous lustre for untreated Aquamarine. Every row carries its source and check date, so each can be traced back individually.
Registered material facts
Each row carries its own source and check date and can be cited on its own; “—” means the cited source gives no value, not “none”.

Testing and market
Heat treatment of Aquamarine is hard to detect: blue-green and yellow beryl coloured by iron can turn blue on heating, and the colour is stable. Filling can be identified: under magnification the exposed filler has a lustre different from the host stone, filled areas may show a flash effect and gas bubbles, infrared spectroscopy can detect the filler's characteristic bands, and luminescence imaging (for example a UV fluorescence viewer) can show where the filler lies. The identification leads for irradiation are: the colour is commonly blue to purple-blue, the UV-visible spectrum shows characteristic absorption peaks caused by irradiation colour centres, and green fluorescence appears under long-wave UV. These leads are cited from GB/T 16553—2017, which can be followed for Aquamarine as a reference only and does not govern it directly. Synthetic Aquamarine is available on the market. Only a laboratory report can say whether a particular Aquamarine is natural or treated.
The tests the CIBJO laboratory protocol requires for this material, and what each method means, are in the protocol table on the laboratory testing page: §6.1.8.
How far testing can go
Aquamarine that has undergone irradiation can be identified by the following features: The colour is commonly blue to purple-blue; the UV-visible spectrum shows the absorption peaks of irradiation colour centres; green fluorescence appears under long-wave UV.
