Any stone experts? Need help Iding some beads!

I picked up these bracelets and I am having trouble figuring out what they are... I have an idea but need help! Sorry in advance for the yellowish lighting!! Hard to get good natural lighting this time of year around here

The first appears to be dragons blood jasper beads with a white jade endless knot?


The second appears to be something I have no idea of. It is reddish brown and has dimple like things on each bead...


The last one was said to be white buffalo turquoise but I know it is often faked and I have a hard time figuring out whats real and what isn't...

 

I see agate beads and the endless knot is probably serpentine jade, these less detailed knots usually are. Serpentine jade is a high quality serpentine.

Possibly jasper. Dimples are often seen on stones from India, but not exclusively those.

White buffalo turquoise is rare and only mined in Nevada. What you have looks like howlite or magnesite.

 

Agate or jasper (about the same stuff, but one is translucent and the other isn't) with a bowenite/serpentine knot, red jasper beads, and the third one isn't faked anything. It's undyed howlite. Magnesite has brown veining.
