Chalcedony /kælˈsɛdəni/ inggih menika satunggaling wujud ingkang sami tumpuk-

tumpukan.^[2] Kuarsa lan moganit

menika kalebet mineral silika, ananging kuarsa menika kagungan perangan trigonal wondene ingkang

moganit menika gadhah sifat ingkang monoklinik. Struktur kimia saking chalcedony inggih menika

SiO₂.

Nama chalcedony menika asalipun saking basa Latin chalcedonius (utawi calchedonius).

Istilah menika ingkang kaping sepisan wonten ing satunggaling karyanipun Pliny the Elder,

Naturalis Historia ingkang dipunginakaken kangge nyebat batuan Jaspis ingkang asifat

transparan.Masalah sitiran: </ref> panutup ora ana tumrap tenger <ref> Ananging

istilah khalkedon (χαλκηδών) menika ugi medal wonten ing Book of Revelation.^[3]

Chalcedony menika nate dipunwastani minangka kriptokristalin kuarsa ingkang gadhah kandhutan

serat^[4] ananging

samenika dipunmangertosi bilih chalcedony menika ugi gadhah sifat ingkang polimorf amargi wonten

moganit wonten ing salebeting chalsedony kasebat.^[2]^[5]^[6] Kadar moganit ing satunggal sampel chalcedony maneka werna, Padatanipun

ing antawisipun 5 dumugi 20 persen.^[7]

Sinaosa gadhah senyawa kimia ingkang memper kaliyan kuarsa, ananging chalcedony menika gadhah sifat

langkung larut tinimbang kaliyan kuarsa wonten ing temperatur ingkang andhap. Bab menika saged amargi

kristal chalcedony menika langkung alus satemah gadhah rasio wiyaring permukaan lan volume ingkang

langkung inggil ingkang dipunprakirakaken amargi wontenipun moganit.^[7]
