It is colorless when pure, but impurities can give it a white, green (asparagus stone), blue (moroxite), yellow, or violet color. Bones are composed of hydroxyapatite, mixed with protein (ossein) and small amounts of other minerals, such as calcium carbonate. Apatite is commercially used as a fertilizer.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31320499"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31457262"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31412285"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31320469"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31376754"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14072261"> <skos:prefLabel xml:lang="es">apatita</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9838325"> <skos:prefLabel xml:lang="ca">apatita</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:32:54</dct:created>  </skos:Concept></rdf:RDF>
