Jade

Jade can refer to two distinct minerals: Nephrite (a variety of the mineral actinolite, Ca2(Mg,Fe)5Si8O22(OH)2) and Jadeite (Na(Al,Fe3+)Si2O6). Based on the image, showing a relatively uniform green color and possibly slight translucence in bead form, it is very likely one of these, but determining which one from a photo is difficult without specific testing.
