Red Agate

A trade colour name for red-orange Agate; goods on the market are often dyed, so without testing it must not be described as natural colour. 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.

This page covers

What we cannot conclude

  • Whether one particular bead is natural, treated or synthetic — only a laboratory report can settle that.
  • Geographic origin, unless an origin report accompanies the item.
  • Price, rarity or investment value: this wiki covers naming and disclosure only.

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

Red agate is a market colour name for red to orange-red agate or chalcedony, not a distinct mineral species. By the prevailing hypothesis, natural red to red-brown agate forms inside volcanic voids as silica-rich fluids fill them in cycles from rim to center; its red band is rich in Fe compounds such as hematite and goethite, and crystallization is linked to Fe3+-rich fluids. Importantly, chalcedony and agate are commonly dyed on the market to enhance or introduce colour, so “red agate” is frequently a dyed treatment product; the red may be natural or treatment-derived.

Scope: Covers the iron-coloured layering mechanism of natural red to reddish-brown agate, and notes that red agate on the market is commonly dyed; does not cover the specific types or origins of dyes.

Where it forms

Gas cavities or voids in volcanic rock (e.g. basalt) filled by silica- and iron-bearing fluids along microfissures.

Sources G&G Fall 2013

Late hydrothermal to supergene setting: iron oxides (hematite, goethite) precipitate from the fluids and impart colour.

Sources G&G Fall 2013

How it forms, step by step

  1. Silica- and Fe3+-rich fluids penetrate a volcanic void along microfissures.

    Sources G&G Fall 2013

  2. The fluids fill the void in cycles from rim to center, precipitating the agate groundmass with thin iron-compound laminae.

    Sources G&G Fall 2013

  3. The red band becomes enriched in Fe compounds such as hematite and goethite, producing the red to red-brown appearance.

    Sources G&G Fall 2013

  4. In the market, chalcedony/agate is commonly dyed to enhance or introduce red colour (a treatment statement).

    Sources G&G Spring 2020 · G&G Summer 2020 · G&G Fall 2013

Link to appearance

The red to red-brown colour is caused by Fe compounds such as hematite and goethite, and one piece may show red, orange-red to red-brown zones. Dyed red is typically concentrated along fractures or at the surface.

Sources G&G Fall 2013 · G&G Spring 2020 · G&G Summer 2020

Timescale

The cited agate study states that silica agate crystallization lasted millions of years and took place in stages; that timescale applies to natural layered agate, whereas dyeing is a rapid artificial treatment and must not be conflated.

Related base materials

  • Chalcedony / agate (microcrystalline quartz, SiO2): colour-variety-of | Red agate is a commercial colour name for red to orange-red agate/chalcedony

Supporting findings

Under the prevailing hypothesis, agate's layered structure arises as silica-rich fluids enter a volcanic void and deposit material in rim-to-centre cycles.

Evidence grade A

Scope: General agate hypothesis, evidenced mainly by Sidi Rahal samples.

Asia

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

The colour of natural red to red-brown agate zones is caused by Fe compounds such as hematite and goethite, and crystallization is linked to Fe3+-rich fluids.

Evidence grade A

Scope: Based on Raman and elemental analysis of Moroccan agate; red agate from other localities may be coloured by different phases.

Sources G&G Fall 2013

Human use and museum objects

Objects discussed under the name "red agate" are mostly recorded as carnelian (chalcedony/agate parent material); one of the earliest is an Indus-style bead of ca. 2900-2350 BCE (Met 59.41.42), recurring in Middle Kingdom Egypt (25.3.252, 15.3.538) and Minoan Crete (26.31.258).

Evidence grade A

Scope: Concerns collection objects of red-to-orange chalcedony; the records do not distinguish natural from heat-induced red, and the commercial name is not implied to have existed in antiquity.

Sources The Met 59.41.42 · The Met 25.3.252 · The Met 15.3.538 +3

Red agate is a commercial colour name for red-to-orange chalcedony/agate; its museum evidence records use of the chalcedony/agate parent (carnelian), not of the name itself. The Met holds an Indus-style carnelian bead of ca. 2900-2350 BCE (acc. 59.41.42, Mesopotamia) and a Dynasty 11 "sweret" bead (acc. 25.3.252, ca. 2051-1981 B.C., Thebes); Middle Kingdom-early New Kingdom carnelian strings (acc. 15.3.538, ca. 1981-1295 B.C.) and Minoan carnelian beads (acc. 26.31.258, ca. 1650-1500 BCE) are likewise of vividly red carnelian. Two Cypriot carnelian beads (acc. 74.51.3143a, b, ca. 1450-1050 BCE) and a Cleveland Museum of Art Dynasty 18 necklace fragment including carnelian (acc. 1915.15, 1540-1296 BCE) continue the tradition. Carnelian is iron-bearing chalcedony; its red colour may be natural or heat-induced, and the records do not distinguish the two.

Sources The Met 59.41.42 · The Met 25.3.252 · The Met 15.3.538 +3

Scope: A museum object evidences only the existence and date of that artefact itself; it does not establish widespread ancient use of the material, nor does it attest the origin, naturalness, or treatment of any modern specimen.

How it is identified

For red agate, colour and banding by themselves do not reveal whether the hue is natural or produced by dyeing or heating, so visual appearance cannot settle naturalness or treatment; a trustworthy identification and any treatment ruling call for instrumental examination at a qualified gem laboratory, and this entry is no basis for self-testing.

Evidence grade A

Scope: Appearance cannot replace identification; naturalness, dyeing or heat treatment must be determined at a qualified gem laboratory, and this entry is not a self-testing basis.

Sources G&G Summer 2014 · CIBJO Gemstone Book 2022

Other research findings

Chalcedony and agate are commonly dyed on the market to enhance or introduce colour, so “red agate” is frequently a dyed treatment product.

Evidence grade B

Scope: The sources document copper-dyed blue chalcedony and quench-crackled dyed material, supporting that dyeing is common for chalcedony, but do not verbatim confirm a specific red dye for “red agate”.

Sources G&G Spring 2020 · G&G Summer 2020

“Red agate” is a commercial colour name for red to orange-red agate/chalcedony, not an independent mineral species or variety.

Evidence grade B

Scope: Defines it as a colour trade name for agate/chalcedony; other red gems (e.g. ruby) are excluded.

Sources G&G Fall 2013

Limits of this research

  • Research status: Formation, occurrence or other material-specific findings found in authoritative sources
  • “Red agate” is a commercial colour name with no independent mineralogical definition.
  • The dyeing evidence comes from copper-dyed blue and quench-crackled chalcedony and does not verbatim establish a specific dye process for red agate; red may be natural or treatment-derived.
  • The iron-colour conclusion rests mainly on one Moroccan locality.

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.

Trade and mineralogical namesRed Agate is a trade name, not a mineralogical species name. Names in four languagesThe four-language names are given in Simplified Chinese, Traditional Chinese, English (Red Agate) and Japanese (a transliteration and a kanji name); the Japanese names are the entry's own, and the Japanese GSJ wording for them is not yet verified by this site. Trade and mineralogical namesThe trade name or synonym is Red agate, and the mineralogical name is reddish-orange chalcedony or agate, often dyed. Chinese standard nameThe GB/T naming counterpart is Agate, and the name itself is not listed in the standard (GB/T 16552—2017 Table A.2, row “Chalcedony (Agate/Jasper)”). Institution usageOf GIA, FTC, CIBJO and Gem-A, the FTC and CIBJO source texts have no wording for this name (checked), and GIA and Gem-A have not been checked; bodies without a recorded wording show the entry's own English name, Red Agate, which does not represent their position. Recommended listing nameThe suggested listing name is red agate (possibly dyed). Sub-names and unacceptable namesRelated high-risk name: the red colour of Red Agate can be natural or dyed and must be disclosed according to testing or the supply chain.

Treatments listed by standards

GB/T Table B.1The treatment classification for Red Agate under GB/T 16552—2017 Annex B, Table B.1 is applied by this site from the Chalcedony (Agate/Jasper) entry of Table B.1; GB/T 16552—2017 does not register the name Red Agate. The Chalcedony (Agate/Jasper) entry of Table B.1 lists: heating, classed as optimization; filling, handled by grades defined on the Gem treatments page; and dyeing, classed as optimization. See alsoThe notes to Table B.1 and the definitions of the filling grades are on the Gem treatments page.

What it is and how it's identified

Among the material facts for Red Agate, chemical composition, fluorescence, UV-visible spectrum, infrared spectrum and magnification are recorded for chalcedony (including agate and jasper, the whole class); see the Chalcedony entry. All values are likewise taken from the cited clauses for chalcedony (including agate and jasper, the whole class), not measured on Red Agate separately. For chalcedony (including agate and jasper, the whole class), the structure is a cryptocrystalline aggregate, which may be compact and massive, spherulitic, radial or microfibrous; Mohs hardness 5–7, no cleavage, density 2.5–2.77 g/cm³; the optic character is that of an anisotropic aggregate; refractive index 1.535–1.539, and this site notes that the clause has further sub-grades and the overall value is registered; birefringence cannot be measured on the aggregate; pleochroism in the untreated state cannot be measured on the aggregate; iridescence and the cat's-eye effect can be seen as optical effects; and in the untreated state the quality factor (lustre) is vitreous to greasy.

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 Red Agate 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 Red Agate (how to read class-level values).

Structure

Red Agate — structure (overall): a cryptocrystalline aggregate, dense and massive in habit; it may also form spherulitic, radial or finely fibrous aggregates.
