Good Morning All! I Need Your Help With A Marking and The Stone. TY!

Hi Everyone! I hope you all are doing well!

I could use your help in identifying the mark JP and I want to know if this stone is tiger eye. I asked because most of these kind of stones I’ve seen online are much more brighter in colors. As always, thank you so much for your help. Stay safe and have a great day!

 

Possibly black diopside,take it outside with the sun overhead for a better photo.

 

Thank you Holly!

 

Hawkseye quartz, looks like. It's the dark brother to tigerseye.

 

Last two photos looks like it could be labradorite.

 

It has that white light ray that moves with it when it is on it

 

Yes it does Everlyb! thank you so much!!

 

My first impression was Labradorite. My father was a geologist and had his tombstone made of it.

 

I think we joolies would have liked your father! A labradoriate tombstone? Pretty awesome.

 

It is. I guess Afghanistan has a lot of Labradorite. He got to see it before he died. You would have liked my dad. A collector of ancient antiques, geologist, historian and wonderful taste in jewelry. he loved to give my mom and his three daughters jewelry. He also had a keen i for identifying time period based on clothing and construction or style. He was better than Google. A lot of knowledge died with him. I learned a lot but wish I could have absorbed it all

 

Your dad and this bunch would have definitely gotten along! IIRC that part of the world is a major source for the stone.
