Batu Giok
Formula Jadeite = Na Al Si2O6
Color = Hijau-putih
Kilap = Kaca ,Vitrous
Kekerasan = 6.5 Skala Mohs
Berat Jenis = 3.2
Pecahan = un even
Kristal = monoclin
Aggregate = massive, granul, vibrous
Assosiasi = schist , serpentine
Daerah dijumpai = Burma (1), Guatemala (2), Ethiopia(3), Indonesia di North Maluku, Obi, Bacan, Kasiruta, Aceh, Papua(5)
Occurancies = dari jenis piroxene group , di daerah serpentinite oleh proses pembekuan cairan hidrothermal akhir
Nephrite
Formula Nephrite = (MgFe)(OHSi4O11)2 Na2Ca4(MgFe)10[(OH)2O2Si16O44]
Kimia = merupaka komposisi hidrous komplek dari mineral amphibolite
Color = pale green, whitish green
Kilap = kusam, dull
Assosiasi = Jadeite
Kekerasan = 5.6
Berat Jenis /SG = 3.0
Occurancies = dijumpai di New Zealand, Kawa-Kawa, berassosiaso dengan batuan serpentinite gabbro
Daerah dijumpai = Pakistan, New Zealand, Jordania
Varian = Actinolite, Tremolite
