Picture Jasper

Also known asLandscape jasper

A commercial appearance name for Jasper whose iron oxide and clay bands form landscape-like patterns; it is not a GB/T variety name. Also known as Landscape jasper. 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.

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.

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

'Picture stone' is an appearance commercial name for the opaque impure microcrystalline quartz (chalcedony/jasper) whose iron-oxide and clay-mineral banding yields landscape-painting-like patterns; it is not a GB/T variety name. Its underlying material is cryptocrystalline silica: fibrous microcrystalline low-α quartz (chalcedony) with other silica polymorphs, and when cut and polished it commonly reveals landscape, stalactite or pipe patterns. The mechanism behind such patterns is that voids in volcanic rock are cyclically filled from rim to centre by silica-rich fluids, producing banding; the shape and width of the zones depend on silica concentration and on temperature, pressure and influx timing, and enrichment of impurities such as iron compounds (hematite, goethite) along the laminae creates colour contrast that reads as a scenic pattern on the polished face.

Scope: Applies to defining the identity of 'picture jasper' as an appearance-based trade name, and the origin of the texture of its underlying microcrystalline quartz; the GB/T clauses could not be verified, and this record contains no standard clause content.

Sources G&G Fall 2013

Where it forms

Voids in volcanic (basalt) rock cyclically filled by silica-rich fluids; patterns revealed on cut faces

Sources G&G Fall 2013

How it forms, step by step

  1. A cavity forms in volcanic rock; silica-rich fluids enter via microfissures and fill it cyclically.

    Sources G&G Fall 2013
  2. Fibrous microcrystalline quartz (chalcedony) grows from rim to centre, forming banding whose geometry is set by silica concentration and by temperature, pressure and timing.

    Sources G&G Fall 2013
  3. Impurities such as iron compounds become enriched along the laminae to form colour bands.

    Sources G&G Fall 2013
  4. When cut and polished, the combination of colour banding and texture reads as landscape, stalactite or pipe patterns, giving the 'picture' appearance.

    Sources G&G Fall 2013

Link to appearance

On cut faces it shows landscape, stalactite or pipe patterns; the patterns come from the overlay of band geometry and impurity (iron-compound) colour bands, and the name is a commercial appearance description.

Sources G&G Fall 2013

Timescale

(Related microcrystalline silica) banded siliceous material formation spans millions to tens of millions of years (GIA 2013; Heaney 1995).

Sources G&G Fall 2013

Related base materials

  • Chalcedony (microcrystalline quartz): variety-of | Picture jasper is a commercial appearance variety of cryptocrystalline quartz (chalcedony/jasper) with picture-like patterns

Supporting findings

The pattern forms because voids in volcanic rock are cyclically filled from rim to centre by silica-rich fluids, producing banding whose geometry depends on silica concentration and on temperature, pressure and influx timing, with impurities such as iron compounds enriching along laminae to form colour bands.

Evidence grade A

Scope: States the banding+colour-band mechanism producing the pattern; no specific locality.

Sources G&G Fall 2013

Causes of colour and optical effects

The appearance results from band geometry controlled by silica concentration, P-T and influx timing, overlaid with impurity (iron-compound) colour, so pattern and colour reflect setting but do not constitute a material identification.

Evidence grade A

Scope: States the relation of colour/pattern to formation conditions; not an identification.

Sources G&G Fall 2013

Where the name comes from

The origin of the appearance trade name "landscape jasper" itself is not given in the cited sources. The etymology below belongs to the underlying mineral quartz: its name is of obscure origin in the Middle Ages, first applied to gangue in Saxony, Germany. This etymology belongs to the underlying mineral, not to the name "landscape jasper" itself.

Evidence grade B

Scope: The etymology explains only the origin of the name; it does not establish the material's composition, locality, naturalness, or treatment.

Sources Handbook of Mineralogy

Other research findings

'Picture stone' is an appearance commercial name for the opaque impure microcrystalline quartz (chalcedony/jasper) showing landscape-like patterns from iron-oxide and clay banding, and is not a GB/T variety name.

Evidence grade A

Scope: Defines the name's status and the material class it describes; does not claim formal standard status.

Sources G&G Fall 2013

When cut and polished, it commonly reveals landscape, stalactite or pipe patterns.

Evidence grade A

Scope: States common pattern types on polished faces; the patterns are not diagnostic.

Sources G&G Fall 2013

Limits of this research

  • Research status: Formation, occurrence or other material-specific findings found in authoritative sources
  • Picture Jasper is an appearance commercial name, not a GB/T variety name; the cited sources give no dedicated definition, and the material attribution rests on its usual classification and evidence from related microcrystalline silica.
  • The full texts of GB/T 16552-2017 and GB/T 34098-2017 are not obtainable; no clause text was verified and no classification table was invented.
  • The alias tuhua biyu ('picture jasper', an old name) is a search term only and is not used as a material determination.

Care and wear

No care facts are recorded for this entry itself. Its parent material has care records: see Jasper.

Durability and wearing

Toughness

tough when massive

Fracture

Conchoidal

Sources Handbook of Mineralogy

Daily wear

Hardness 7 resists scratching by ordinary metal and grit, and massive material has good toughness, so it is relatively durable for daily wear; however a hard impact can still chip it, and sudden temperature changes should be avoided to prevent cracking.

Care

Warm water with mild soap and a soft brush suffices; rinse and dry with a soft cloth. For dyed, resin-impregnated or fractured treated material, avoid ultrasonic/steam cleaning and acid washes, and avoid prolonged heat or sunlight.

General guidance: LumaLark's general guidance inferred from the material's properties (hardness, toughness, cleavage); not text from the cited source, and not a guarantee for any specific piece.

Scope: This field describes the material's general properties and is not a finished-product durability promise; it gives no warranty of any specific piece's durability or safety, and the durability of treated (filled, dyed, coated) or composite/assembled material must be assessed separately.

Treatments and identification leads

Each CIBJO value links to its entry under “Testing and market”, where the wording and source are given in full.

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 in four languagesThe names of Picture Jasper are given in Simplified Chinese, Traditional Chinese, English (Picture Jasper) and Japanese (a katakana transliteration); its identity tier is registered as commercial/trade name. Standard and listing namesThe corresponding national-standard name is jasper, falling under GB/T 16552—2017 Table A.2, row Chalcedony (Agate/Jasper), and the original does not list the name picture jasper; the suggested listing name is Picture Jasper (jasper; quartz-based). Sub-names and unacceptable namesOther market names include picture jasper in another Chinese form and Landscape jasper; an older Chinese name is used only as a misuse search term, may appear only as a note and not as the main product name, and is linked to a high-risk name for jasper. The mineralogical description presents picture jasper as opaque, impure microcrystalline quartz (chalcedony), with iron oxide and clay bands forming landscape-like patterns. Japanese namesThe entry's own Japanese name is the katakana transliteration, and Japan's GSJ wording for it is not yet verified by this site. Institution usageThe entry's own English name is Picture Jasper: the FTC and CIBJO texts on file, when checked, have no wording for this name, and GIA and Gem-A are unchecked; bodies without a recorded wording show the entry's own English name, which does not represent their position.

What it is and how it's identified

Among the registered material facts for Picture Jasper, chemical composition, luminescence, UV-visible spectrum, infrared spectrum and magnification are written in the cited clause for chalcedony (including agate and jasper, the whole class); see the Chalcedony entry. Registered for chalcedony (including agate and jasper, the whole class), Picture Jasper has a cryptocrystalline aggregate structure, compact and massive, and may also form spherulitic, radiating or microfibrous aggregates; Mohs hardness 5–7, cleavage none, density 2.5–2.77 g/cm³; these are not measured on Picture Jasper alone. The optical items registered for chalcedony (including agate and jasper, the whole class) are: optical character anisotropic aggregate; refractive index 1.535–1.539 (the site note explains that the clause has finer sub-ranges and the overall value is registered); birefringence not measurable on an aggregate; pleochroism not measurable on an aggregate when untreated; the untreated quality factor lustre is vitreous to greasy; and both iridescence and the cat's-eye effect can occur.

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 Picture Jasper 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 Picture Jasper (how to read class-level values).

Structure

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