Bovine Horn
Also known asHorn bead
Keratin horn material from cattle, an organic material of animal origin; sourcing, processing and import requirements must be checked for the target market. 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
Cattle horn is the horn material of bovids, an animal-derived keratinous organic material used as an organic gem material in the trade. CIBJO's material table lists Horn as an organic gem material and notes possible treatments such as bleaching, dyeing, impregnation and waxing. Note: the cited sources include no dedicated authoritative material-science reference for cattle horn or for keratin composition/structure, so the formation mechanism of horn and the chemistry of keratin cannot be stated from them; a specimen's material identity, and its distinction from protected animal materials (e.g. rhino horn, tortoiseshell, ivory), require laboratory testing.
Scope: Covers the category and possible treatments of bovine horn as an organic gem material; not to be used for assessments of composition, formation, identity or origin of bovine horn samples.
Sources CIBJO Gemstone Book 2022
Where it forms
Animal horn, an integumentary structure, grows on the living animal and is not a geological product; the cited sources do not describe its formation environment further.
Sources CIBJO Gemstone Book 2022
How it forms, step by step
Horn grows on the living animal (the mechanism is not described in the cited sources).
Sources CIBJO Gemstone Book 2022
The horn is worked (cut, polished, heat-pressed) into gem/decorative material.
Sources CIBJO Gemstone Book 2022
The finished material may be bleached, dyed, impregnated or waxed to alter appearance or stability.
Sources CIBJO Gemstone Book 2022
Identity and distinction from protected animal materials require laboratory testing.
Sources CIBJO Gemstone Book 2022
Link to appearance
Horn's appearance (tone, texture, lustre) depends on its keratin structure and working/treatment and can be altered by bleaching or dyeing; appearance cannot establish identity.
Sources CIBJO Gemstone Book 2022
Timescale
The cited sources give no absolute timescale for horn as a material.
Sources CIBJO Gemstone Book 2022
Other research findings
CIBJO's material table lists Horn as an organic gem material and notes possible treatments such as bleaching, dyeing, impregnation and waxing.
Evidence grade AScope: Nomenclature/category level; does not establish a specimen's naturalness, treatment or origin.
Sources CIBJO Gemstone Book 2022
CIBJO classifies animal-origin organic materials (such as ivory) alongside plant-origin materials, with Horn being an animal-origin organic gem material.
Evidence grade AScope: Category-membership level; does not prove any specimen's species or treatment.
Sources CIBJO Gemstone Book 2022
The cited sources contain no dedicated authority for cattle horn or keratin composition/structure, so its material identity requires testing.
Evidence grade CScope: Flags an evidence gap; it does not mean cattle horn does not exist or is unusable, only that no name-specific authoritative source has been found.

Limits of this research
- Research status: Only partial material-specific findings found; gaps are stated as gaps
- No dedicated authoritative material-science source for cattle horn or keratin was included; its formation mechanism or chemistry cannot be stated from these sources.
- A specimen's identity (cattle horn/rhino horn/tortoiseshell/ivory, etc.), treatment and origin cannot be determined here and require laboratory testing.
- Distinction from protected animal materials requires dedicated testing.

Names
Besides Bovine Horn, the name register records "Horn bead", for which no restriction on use as a name is recorded.
Standard and listing namesBovine Horn can be named directly under GB/T 16552—2017: Annex A of this standard does not list it, and the naming rules allow mineral, rock and material names not included in Annex A to be used directly. The suggested listing name is horn bead, and the trade name/synonym is the English Horn bead. Names in four languagesNames are given in Simplified Chinese, Traditional Chinese, English (Bovine Horn) and Japanese; the Japanese name is the entry's own, and the wording used by GSJ (Japan) for this name is not yet verified by this site. Institution usageOn authority wording, the FTC and CIBJO texts contain no wording for this name (checked), while GIA and Gem-A are unchecked; bodies without a recorded wording show the entry's own English name, Bovine Horn, which does not represent their position. Trade and mineralogical namesThe mineralogical name can be paraphrased as keratinous animal horn material.

- Sample actually measured
- water buffalo horn sample only
- Qualification
The sample the report measured is water buffalo horn (water buffalo and cattle both belong to the subfamily Bovinae). It did not test cattle horn, so this is not a measured value for cattle horn. The report we cite measured hardness only, with no figure for toughness or stability.
