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
Bloodstone (also heliotrope) is the variety of green chalcedony containing red spots. Its genesis follows the chalcedony parent material: silica-rich fluids fill voids or fissures in the host rock cyclically from the rim toward the centre, precipitating layer by layer to form microcrystalline quartz. Its characteristic red spots are caused by Fe compounds such as iron oxide (hematite) — in banded chalcedony, red or brown-red parts are coloured by Fe compounds such as hematite and goethite, and Fe-bearing phases together with other solid inclusions incorporated under hydrothermal or hypogenic conditions make up the red spots in the chalcedony matrix. The green body colour of bloodstone comes from a separate colouring factor requiring separate identification. Chalcedony (including bloodstone-type material) may also be dyed, so natural and treated colour must be distinguished in identification.
Scope: Used to explain how bloodstone inherits the cavity-filling origin of chalcedony, and that its red spots derive from iron-bearing compounds such as iron oxides (hematite); the origin of the green body colour must be determined separately.

Where it forms
Voids and vesicles in volcanic rock (geodes, vugs) and fissures in sedimentary rocks, where silica-rich fluids fill them cyclically to form chalcedony.
Sources G&G Fall 2013
Later hydrothermal and hypogenic settings, where Fe-bearing phases and other solid inclusions are incorporated into the silica matrix to form red spots.
Sources G&G Fall 2013
How it forms, step by step
Silica-rich fluids enter voids or fissures in the host rock.
Fluids circulate from the rim toward the centre, precipitating silica layer by layer as fibrous microcrystalline quartz (chalcedony).
Fe compounds (such as hematite) and solid inclusions incorporated under hydrothermal/hypogenic conditions are distributed in the matrix, forming red spots.
The green body colour arises from a separate colouring factor requiring separate identification, and chalcedony-type material may also be dyed.
Link to appearance
Green opaque-to-translucent chalcedony matrix with scattered red spots; the red spots are caused by iron oxide such as hematite, while the green body colour requires separate identification.
Sources G&G Fall 2013
Timescale
Sidi Rahal agate (chalcedonic) crystallization lasted millions of years and proceeded in stages; the moganite-to-low-quartz transformation generally occurs over tens of millions of years and can serve as a relative age indicator.

Supporting findings
Bloodstone inherits the chalcedony parent-material genesis: silica-rich fluids fill voids or fissures cyclically from rim to centre, precipitating microcrystalline quartz layer by layer.
Evidence grade AScope: Describes chalcedony's filling genesis; bloodstone's occurrence details are not covered individually.
Fe-bearing phases and other solid inclusions were incorporated into the silica matrix under later hydrothermal or hypogenic conditions, forming the red spots in the chalcedony.
Evidence grade AScope: A general account of inclusion incorporation in chalcedony; the exact mineralogy of bloodstone's red spots needs case-by-case identification.

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
Bloodstone is the variety of green chalcedony containing red spots; the red spots are caused by Fe compounds such as iron oxide (hematite).
Evidence grade AScope: The iron-oxide red cause is drawn from studies of Fe-rich red zones in banded chalcedony, not from bloodstone specimens specifically.
Other research findings
As chalcedony, bloodstone has a refractive index of about 1.53–1.54 and specific gravity of about 2.48–2.65, composed of quartz (possibly with moganite).
Evidence grade AScope: Laboratory ranges for chalcedony; iron admixture may slightly shift specific gravity.
Limits of this research
- Research status: Formation, occurrence or other material-specific findings found in authoritative sources
- The authoritative sources do not specifically discuss bloodstone; the red-spot colour cause is extrapolated from Fe-rich red zones in banded chalcedony.
- The colouring factor of bloodstone's green body colour (e.g. chlorite and other mineral inclusions) is not covered by the cited sources and requires separate identification.

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. Source: §5.4.2.1 a), b); §5.4.2.2 a)
- 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.

Names
Besides Bloodstone / Heliotrope, the name register records "Heliotrope", for which no restriction on use as a name is recorded.
Chinese standard nameBloodstone / Heliotrope is not listed by name in the GB/T 16552—2017 nomenclature; the name comparison gives chalcedony as the national-standard naming counterpart, based on the "Chalcedony (Agate/Jasper)" row of GB/T 16552—2017 Table A.2. Names in four languagesThe four-language names cover Simplified Chinese, Traditional Chinese, English (Bloodstone / Heliotrope) and Japanese. Recommended listing nameThe suggested listing name is "Bloodstone"; the GB/T 16552—2017 naming rules require that a trade name should not be used on its own, so the label should give the basic name of the material followed by the trade name. Trade and mineralogical namesHeliotrope is an English trade name and synonym. The mineralogical name is described as green chalcedony with red iron-oxide spots. Institution usageOn wording checks, this site has not yet verified the wording of GIA, FTC, CIBJO, Gem-A or GSJ (Japan) for this name; the English name Bloodstone / Heliotrope and the Japanese name are the entry's own forms and do not represent the position of any body.

What it is and how it's identified
The material facts for Bloodstone / Heliotrope registered under GB/T 16553—2017 come from clauses written for chalcedony (including agate and jasper, the whole category), not data measured on bloodstone alone. Values taken from chalcedony (including agate and jasper, the whole category): a cryptocrystalline aggregate, compact and massive, which may also form spherulitic, radiating or microfibrous aggregates; Mohs hardness 5–7; no cleavage; density 2.5–2.77 g/cm³; optically an anisotropic aggregate; refractive index 1.535–1.539, the clause also having finer sub-ranges, with the overall value registered (this site's note); birefringence cannot be measured in aggregates; when untreated, pleochroism cannot be measured in aggregates and the quality factor (lustre) is vitreous to greasy; iridescence and cat's-eye effect may both be seen. Chemical composition, fluorescence, UV-Vis spectrum, infrared spectrum and magnification are written for chalcedony (including agate and jasper, the whole category) in the chalcedony entry.
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 chalcedony, including agate and jasper (the whole class), so they are not repeated on the Bloodstone / Heliotrope page; see the material facts on the Chalcedony entry.
Items below that name the class they cover give the cited clause’s value for that whole class, not a measurement of Bloodstone / Heliotrope (how to read class-level values).
Structure
Bloodstone / Heliotrope — structure (overall): a cryptocrystalline aggregate, dense and massive in habit; it may also form spherulitic, radial or finely fibrous aggregates.

Clause-level definitions
Bloodstone / Heliotrope is defined directly in CIBJO Gemmological Laboratories Book 2024 under the entry name Heliotrope (bloodstone). The CIBJO definition gives the mineral species as quartz and the mineral/gem variety as heliotrope (bloodstone), noting that the CIBJO wording is quoted in full under Clause-level definitions on this page. The cross-check result is that it is defined directly by CIBJO, and no identically named English entry was found in the GB/T annex.
