Jade

There are two distinct minerals commonly known as Jade: Nephrite (a calcium magnesium silicate - Ca2(Mg,Fe)5Si8O22(OH)2) and Jadeite (a sodium aluminum silicate - NaAlSi2O6). Based on the image showing a typically softer, more fibrous appearance, it is likely Nephrite.

Quartzite with Hematite staining

Metamorphosed Quartz Sandstone (SiO2)

White Sapphire

Corundum (Al2O3)
