Morganite

Also known asPink beryl

A pink to peach-orange variety of beryl. Irradiation and heat treatment are common, so natural color cannot be assumed. 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.

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

Morganite is the pink gem variety of beryl (Be3Al2Si6O18) in the beryl family and forms chiefly in granitic pegmatites. As is typical of many pegmatite gems, morganite can grow to large size; Brazilian miners have recovered crystals weighing about 22 lb (10 kg). Pegmatites are usually mined from solidified, magma-released aqueous fluids and are a typical host for beryl-group minerals. Supplying most of the morganite traded worldwide are pegmatite workings in Minas Gerais, Brazil; Afghanistan, Mozambique, Namibia and the US are minor and inconsistent sources, while the original Madagascar deposit is known for magenta rough.

Scope: Covers morganite produced in pegmatites; its specific colouring-element mechanism is not directly described in the cited authoritative sources.

Sources GIA Morganite Description

Where it forms

Granitic pegmatites, formed from solidified magma-released aqueous fluids, are the main setting for morganite.

Sources GIA Morganite Description

Pegmatite fields such as Minas Gerais (Brazil) as the main source; Afghanistan, Mozambique, Namibia and the US as minor sources.

Sources GIA Morganite Description · G&G Summer 2025

How it forms, step by step

  1. Magmatic fractional crystallisation enriches the late residual melt in Be and other rare alkalis plus volatiles.

    Sources G&G Summer 2025 · GIA Morganite Description
  2. An aqueous fluid exsolves from the melt and solidifies to form the pegmatite.

    Sources GIA Morganite Description
  3. In pockets of the core/intermediate zones, beryl (morganite) crystallises as large crystals.

    Sources GIA Morganite Description

Link to appearance

Morganite shows pink tones and can form large, transparent crystals; its pink colour is part of beryl's wide colour range.

Sources GIA Morganite Description

Timescale

Crystallises at the late, water-rich stage of magmatic evolution; growth in pegmatites can be fast (millimetres to over a metre per day).

These are localities recorded by authoritative sources, not an origin finding for any individual piece. The CIBJO Gemstone Book (2022, §4.2.3) says a place of origin names where a gem was mined or harvested, is a matter of opinion, does not imply a level of quality, and that cutting, processing or exporting centres must not be used to imply origin. See how far testing can go on this page, the origin determination guide and the overview of recorded localities.

How it is identified

Morganite's pink colour does not by itself prove natural, untreated beryl. Internal features seen under the microscope, and trace-element chemistry obtained by EDXRF, are what help separate natural beryl from synthetic or treated material; these require laboratory instruments, and the final call should be made by a qualified gem laboratory, not by a viewer.

Evidence grade A

Scope: 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.

Sources G&G Winter 2016

Morganite, the pink beryl, is often priced on locality, with goods traded under names such as Madagascar, Brazil or Afghanistan. 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.

Answer at a glance

Morganite is often subjected to heating and irradiation. Under GB/T 16552-2017, heating counts as an optimization, so the plain gem name may be used (§5.4.2.1 a); irradiation counts as a treatment and must be stated in the name (§5.4.2.2 a). Do not assume it is unenhanced.

Common care questions and matching entries

CleaningCare of Morganite: the Gemological Institute of America (GIA) care and cleaning guide for morganite states that, regardless of treatment status, warm soapy water is always safe for morganite, and that ultrasonic and steam cleaning are usually safe too, except for stones with liquid inclusions or fractures; occasional morganite with filled fractures, whose status is treated and only where filled, should be cleaned only with warm soapy water. GIAThe GIA guide also states that, regardless of treatment status, morganite should not be exposed to heat, its colour is stable in light and will not fade, and it is attacked by hydrofluoric acid. Special careThe 17th edition of the American Gem Trade Association (AGTA) Gemstone Information Manual states that morganite whose colour has been improved by heat treatment or irradiation needs special care (marked SC); the status is treated, and this applies only to heat treatment and irradiation.

Treatments and identification leads

Registered treatmentsThe treatment registered for Morganite is heating, with the status treated. Identification cluesThe identification leads for heating are that it is mostly used to remove the yellow tint from Morganite to obtain a pure pink, and that it is hard to detect and stable up to 400°C. Values not givenStability and prevalence for heating are both marked “—”, meaning the cited source gives no value, not “none”. The source for heating is the heating clause of GB/T 16553—2017.

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.

What it is and how it's identified

Morganite is the pink variety of beryl, with composition (phase) beryl; structure, durability and physical and optical properties are mostly taken for beryl (the whole mineral species). For beryl (the whole mineral species), the structure is crystalline, hexagonal system, with a hexagonal prismatic habit, occasionally hexagonal tabular, and crystal faces often show longitudinal striations; Mohs hardness 7.5–8; cleavage one direction, imperfect. For beryl (the whole mineral species), density is 2.67–2.9 g/cm³, converted from the cited clause value of 2.72 with stated tolerances of +0.18 and −0.05; optic character anisotropic, uniaxial negative; refractive index 1.56–1.6 and birefringence 0.005–0.009, the refractive index range being converted from the clause value of 1.577–1.583 with a tolerance of ±0.017. When untreated, Morganite shows weak to moderate pleochroism in pale red and purplish red; when untreated, the lustre taken for beryl (the whole mineral species) is vitreous.

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”.

Chemical composition, luminescence, UV-visible spectrum, infrared spectrum, magnification: these whole-class features are given in the cited clause for beryl (the whole mineral species), so they are not repeated on the Morganite page; see the material facts on the Beryl entry.

Items below that name the class they cover give the cited clause’s value for that whole class, not a measurement of Morganite (how to read class-level values).

Testing and market

In the CIBJO laboratory protocol, Morganite is listed under beryl; for identification see the Beryl entry, and the list of required methods is on the laboratory testing page. Heated Morganite has identification leads: heating is mostly used to remove the yellowish tone from Morganite to obtain a pure pink; heating is hard to detect and is stable below 400 °C. The cited conclusion applies only to heated Morganite, and the cited GB/T 16553—2017 serves only as a reference for the Morganite entry and does not govern it directly.

The CIBJO laboratory protocol covers Morganite under “Beryl” (§6.1.12): see identification on the Beryl entry; the required tests are listed on the CIBJO laboratory protocol table for Beryl.

How far testing can go

Morganite that has undergone heating can be identified by the following features: commonly used to remove the yellow tint in morganite and produce a pure pink; hard to detect; stays stable below 400 °C.

Who maintains this page

The material facts in the Morganite entry are maintained by the LumaLark wiki and matched one by one to the standard clauses or institutional sources they cite: every fact carries its source (with a clause or page locator) and a check date, so it can be traced back to the original; clause-level definitions also carry a cross-check result. The entry exists so that buyers and sellers can check naming, disclosure and material facts item by item.
