3 Pieces Mexican Jewelry. Help with the Stones

My latest collection of Mexican jewelry. In process of going through the books to identify the Taxco and other hallmarks on the backs. Any idea what the stones are? Thanks

 

Lapis, onyx & ?

 

Well, maryisgal, you probably know better than I, but I would have said "Lapis, onyx &?"

oh......................

 

I agree with the first two stone IDs, the third looks to me like Bloodstone.

 

Random dyed blue rock, obsidian/onyx and random dyed red rock. It wants to be red coral but isn't, and the blue is in no way shape or form lapis. Bloodstone is green with red flecks, generally. Age on these is 1990s or later, best guess. I'd have to see the marks to be sure, but the design of the pendants isn't vintage in any way.

 

Think the blue is dyed. Second does look like black onyx. Third might be carnelian.

 

Carnelian is a translucent orange or orange-red. This is opaque red with black marbling. My best guess is howlite; it has those markings and takes dye well.

 

It could be Mexican red jasper.

 

Here is another picture of the blue stone. It looks translucent? If that's the correct term! I don't think it is jasper. Thoughts?

 

More like catseye glass. Those are often set in sterling.

 

The red one has a sleek, classy modernist look. I would guess made by Enrique Ledesma or someone imitating his style.
