Amber with Animal Inclusion

Also known asInsect amber (conditional name)

A trade name for Amber containing animal inclusions, listed under the "Amber" row in GB/T Appendix A Table A.3; whether the inclusions are genuine must be identified. 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.

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

“Amber with Animal Inclusion” is a commercial name for amber that contains animal inclusions; it is not an independent mineral species or material type. Amber itself is a biogenic organic gem: resin secreted by ancient trees hardens and fossilizes; while the resin is still soft and hardening, once-living animal remains become trapped inside as inclusions. The parent resin matures after burial in sediment (drying, loss of volatiles/labile components, possible polymerization/cross-linking), during which the inclusions are preserved.

Scope: Applies to the formation of the amber (fossil resin) referred to as "amber with animal inclusion" and of its inclusions, and defines it as a trade name based on inclusions; no mineral-species assertion is made for this Chinese trade name.

Sources GIA Amber Description · Journal article (resin maturation)

Where it forms

Resin exuded by ancient trees is buried in sediment and matures there.

Sources GIA Amber Description · Journal article (resin maturation)

Before/while hardening the resin can entomb biological remains as inclusions.

How it forms, step by step

  1. Resin, or sap, is exuded by ancient trees.

    Sources GIA Amber Description · Journal article (resin maturation)
  2. While hardening, the resin traps animal inside.

    Sources GIA Amber Description · Journal article (resin maturation)
  3. The resin is buried in sediment and matures.

    Sources GIA Amber Description · Journal article (resin maturation)
  4. The resin hardens into amber containing inclusions.

Link to appearance

Amber may contain animal inclusions visible to the unaided eye or with magnification; NOTE: the authenticity and identity of inclusions require testing and cannot be settled by appearance alone.

Sources GIA Amber Description

Timescale

The sources require amber to be older than a million years and report that its creation took place tens of millions of years in the past.

Sources GIA Amber Description

Related base materials

  • Amber (fossil resin): Amber with animal inclusions is a commercial name for amber classified by the animal inclusions it contains, not a separate material type

Supporting findings

Amber is a biogenic organic gem, formed when resin secreted by ancient trees hardened and fossilized.

Evidence grade B

Scope: Applies to amber overall; not the inclusion trade name.

Sources GIA Amber Description

The parent resin, buried in sediment, matures (drying, loss of volatiles/labile components, and possible polymerization/cross-linking into a macromolecule).

Evidence grade A

Scope: A maturation mechanism from experimental simulation; describes fossilization.

Sources Journal article (resin maturation)

The sources require amber to be older than a million years and report that its creation took place tens of millions of years in the past.

Evidence grade B

Scope: Gives amber's age boundary; not the inclusions.

Sources GIA Amber Description

Other research findings

Scientists and collectors treasure amber that contains suspended animal or plant fragments; these fossilized bits of once-living things were trapped in the hardening amber, creating a time capsule.

Evidence grade B

Scope: Describes how inclusions are entombed; not the identification of a specific inclusion.

Sources GIA Amber Description

“Amber with Animal Inclusion” is a commercial name for amber divided by its animal inclusions, not an independent mineral species or material type; the cited authoritative sources give no definition of this Chinese trade name.

Evidence grade C

Scope: Defines it as a commercial name; no authoritative mineralogical definition.

Sources GIA Amber Description

Limits of this research

  • “Amber with Animal Inclusion” is a commercial name for amber (divided by inclusions); none of the authoritative sources consulted gives it a mineralogical definition.
  • The authenticity and identity of inclusions require testing and cannot be settled by appearance alone.

Answer at a glance

"Amber with Animal Inclusion" is a market name rather than a mineral species name; before using it, verify: Laboratory identification required before the name is used.

Evidence

  • GB/T · Table A.3, row 琥珀 (Amber)

What this means for you

Before buying, check the recommended listing name "Amber with animal inclusion" and any disclosed treatments on this page, and ask the seller for a grading report if in doubt.

Treatments and identification leads

One row per treatment, with three standards side by side: how often it occurs and how stable it is (CIBJO), its category in GB/T 16552—2017 Table B.1 (this site's paraphrase) and how the JJA/AGL 2025 table lists it. 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.

  • 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.

Treatments listed by standards

Treatments for Amber with Animal Inclusion are classified by this site applying the “Amber” row of GB/T 16552—2017, Annex B, Table B.1. The treatments named in the Amber row of Table B.1 are heating, filling, coating, irradiation, colour change by heating under pressure, and dyeing; heating is listed as an optimization, filling and coating are both graded, and irradiation, colour change by heating under pressure and dyeing are listed as treatments. The full row, with the effect column, is on the Amber page; what Table B.1 is and how the grades are defined are on the Gem treatments page.

What it is and how it's identified

Amber with Animal Inclusion is amber enclosing insects or other organisms. Registered for amber (the whole class): structure (overall) amorphous, Mohs hardness 2–2.5, no cleavage, triboelectricity: becomes charged when rubbed, optic character isotropic, with strain often causing anomalous extinction and interference colours, and no birefringence. For amber (the whole class), density is 0.96–1.1 g/cm³; site note: the cited clause gives 1.08 with a stated tolerance of (+0.02, −0.12), and the range shown is worked out from that. For amber (the whole class), refractive index is 1.54; site note: 1.54 is the reading commonly obtained with the spot method under the cited clause, a typical value rather than an absolute limit, and the clause also gives finer sub-ranges, with the overall value used. For amber (the whole class), untreated, the quality factor (lustre) is resinous.

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 amber (whole class), so they are not repeated on the Amber with Animal Inclusion page; see the material facts on the Amber entry.

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