Burma Ruby
Also known asMyanmar ruby · Pigeon’s blood ruby (conditional name)
A Ruby trade name historically associated with the mines of Myanmar (Burma); it is not a separate mineral species and is not in itself proof of origin. Also known as Myanmar ruby, Pigeon’s blood ruby. 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
Burmese ruby is a geographic trade name for ruby (red corundum, Al2O3) historically from Myanmar (e.g., the Mogok area); the material itself remains corundum, and its red colour comes mainly from Cr3+ substituting for Al3+ in the corundum lattice. Ruby generally forms in metamorphic, non-basalt-related settings (e.g., marble or amphibolite host rocks) and in placers—for example, Mozambique's Montepuez ruby is hosted in amphibolite within a complex that underwent amphibolite-facies metamorphism. However, the sources cited here do not record the deposit type, host rock, or age of Myanmar ruby at Mogok; that Myanmar-specific content is flagged as an explicit gap and is not substituted with data from Mozambique or elsewhere.
Scope: Used to explain that Burma ruby is an origin trade name and the material is corundum, and gives the general metamorphic origin of ruby; geological content specific to Myanmar is marked as a gap.
Sources G&G Spring 2015
Where it forms
Metamorphic, non-basalt-related settings such as marble or amphibolite host rocks (general ruby hosts).
Sources G&G Spring 2015
Example, Mozambique's Montepuez: ruby hosted in amphibolite within a complex that underwent amphibolite-facies metamorphism (~0.4-1.1 GPa, 550-750°C), with ruby formation apparently involving metasomatism.
Sources G&G Spring 2015
(Gap) These sources record no host rock or tectonic setting for Myanmar (e.g., Mogok) ruby.
Sources G&G Spring 2015
How it forms, step by step
In a metamorphic setting, corundum crystallizes where there is a sufficient supply of aluminium, chromium, and oxygen (ruby forms only in a narrow window).
Cr3+ substitutes for Al3+ in the corundum lattice, colouring the corundum red (pink).
(Mozambique example) Fluids derived from a parental magma reacted metasomatically with low-silica host rocks, promoting ruby formation.
(Gap) The specific formation process of Myanmar ruby deposits is not recorded in these sources.
Link to appearance
Red is caused by Cr3+; chromium and iron contents together affect the purity of the red and its fluorescence (iron can suppress chromium-related fluorescence).
Sources G&G Spring 2020
Timescale
These sources give no absolute age for Myanmar ruby, so none is asserted. For reference, the Pan-African belt hosting Mozambique's Montepuez is Neoproterozoic (~500-800 Ma), but this does not license any age for Myanmar ruby.
Sources G&G Spring 2015
Related base materials
- Corundum: Burma ruby is a geographic-origin trade name for ruby (red corundum); the material is still corundum, not an independent material
Supporting findings
Ruby commonly forms in metamorphic, non-basalt-related settings: at Mozambique's Montepuez, ruby is hosted in amphibolite within a complex that underwent amphibolite-facies metamorphism (~0.4-1.1 GPa, 550-750°C), and ruby formation appears to involve metasomatism.
Evidence grade AScope: Data from Mozambique's Montepuez, offered as a general example of metamorphic ruby, not as Myanmar.
(For comparison) The ruby-bearing metamorphic complex of Mozambique lies within a Neoproterozoic (~500-800 Ma) Pan-African orogenic belt; this is Mozambique data and cannot be used to infer the age of Myanmar ruby.
Evidence grade BScope: Mozambique belt age; explicitly not Myanmar.
Recorded localities
Authoritative sources name a single or principal locality.
Asia
- Mogok area, Myanmar
Sources Gems & Gemology 1983
- Mong Hsu, Shan State, MyanmarMajor new locality from the 1990s; its rubies typically require heat treatment.
Sources Gems & Gemology Winter 2000
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.
Causes of colour and optical effects
Ruby's red colour comes from Cr3+: Cr3+ is the red (and pink) colouring agent in corundum; with other chromophores such as h•-Cr3+ it determines corundum's many colours.
Evidence grade AScope: General corundum colour mechanism; not measured on Myanmar samples.
How it is identified
The appearance of Burmese ruby can closely match rubies from other localities, colour alone cannot prove origin, and some sources overlap in their features. Origin determination is a laboratory procedure based mainly on internal inclusion features and trace-element suites measured with instruments such as LA-ICP-MS and compared against reference data; origin conclusions carry overlap and uncertainty and must be issued by an accredited laboratory, and this entry gives no self-identification criteria.
Evidence grade AScope: Appearance is insufficient to settle origin; determination requires testing by an accredited laboratory, and this entry gives no self-test criteria or threshold.
In "Burmese ruby" the locality in the name is a trade attribution, not a determined origin. Origin labels for ruby (corundum) (Myanmar, for instance) are often used to support a premium, yet origin cannot be inferred from appearance or name. Origin determination is a comparison against reference databases of known localities: a laboratory measures trace-element suites by LA-ICP-MS and weighs internal inclusion features against specimens of documented provenance. The judgement is relative - the characteristic ranges of different localities overlap, deposits with no reference material cannot be assigned, and a single deposit is internally variable; treatment alters the measurable features, so treatment status must be settled first. An origin call must be issued by an accredited laboratory for a specific specimen, and "consistent with a locality" is not the same as "mined there"; nor does a place name in the trade prove quality.
Evidence grade AScope: Origin cannot be inferred from appearance or name; the locality in the name is a trade attribution, not a determined origin; a conclusion must be issued by an accredited laboratory for a specific specimen; no self-test criteria are given here.
Other research findings
‘Burmese ruby’ is a geographic trade name for ruby (corundum); under CIBJO, geographic names denote only where a gem was mined or harvested, origin determination is a matter of opinion, and origin does not imply quality.
Evidence grade AScope: Naming/place-of-origin rules; not Myanmar deposit geology.
Sources CIBJO Gemstone Book 2022
The sources cited here do not cover Myanmar ruby deposits: Myanmar appears only as a sample source or as a metamorphic-sapphire comparison (e.g., Mogok); its deposit type, host rock, and age are gaps that must not be filled with Mozambique or other localities' data.
Evidence grade CScope: Negative evidence—an explicit check that the reviewed sources do not document Myanmar ruby deposits.
Limits of this research
- Research status: Formation, occurrence or other material-specific findings found in authoritative sources
- None of the reviewed sources documents Myanmar (e.g., Mogok) ruby deposits; Myanmar ruby formation and age are data gaps.
- Ruby in amphibolite-facies metamorphism at ~0.4-1.1 GPa/550-750°C is Mozambique (Montepuez) data, general background only, not to be presented as Myanmar.
- Myanmar appears only as a sample source (colour study) and as a metamorphic-sapphire comparison (Mogok).
- The place-name rules for ‘Burmese ruby’ follow CIBJO (level A).

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
The registered material facts for Burma Ruby are written by the cited clauses for ruby as a whole (any origin) and are not measured on Burma Ruby separately. For ruby as a whole (any origin), the structure is crystalline and trigonal, with a crystal habit that is hexagonal prismatic or barrel-shaped, and occasionally tabular or platy; Mohs hardness is 9; there is no cleavage, but stones with well-developed twinning may show parting in three directions. For ruby as a whole (any origin), the density of 3.95–4.05 g/cm³ is derived from the cited clause value of 4.00 with a tolerance of ±0.05, the refractive index of 1.757–1.779 is derived from the cited clause value of 1.762–1.770 with a tolerance of +0.009/−0.005, and birefringence is 0.008–0.01. For ruby as a whole (any origin), the optic character is anisotropic, uniaxial negative; pleochroism in the untreated state is strong, purplish red and orangey red, and the lustre in the untreated state is vitreous to subadamantine; as optical effects, the cat's-eye effect is rare and asterism commonly appears as six-rayed stars, with separate CIBJO explanations for the cat's-eye effect and asterism.
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, long-wave UV luminescence, short-wave UV luminescence, UV-visible spectrum, infrared spectrum, magnification: these whole-class features are given in the cited clause for ruby as a whole (not one origin), so they are not repeated on the Burma Ruby page; see the material facts on the Ruby entry.
Items below that name the class they cover give the cited clause’s value for that whole class, not a measurement of Burma Ruby (how to read class-level values).
