Question about "stones," adjustable ring in VTG costume jewelry

There were three ladies rings in that gentleman's jewelry box. The first (an eye-catcher) was also adjustable, with a fat emerald green cabochon that feels like acrylic.

But this one felt a bit heavier. So I clicked the turquoise colored stones against a tooth, and they feel like stone, or glass. What would they likely be?
From the side.

From the top. I notice that in this close-up, they look like real stones. Chips possibly? (But in costume jewelry?)

From the back (with apologies for the imperfect focus; I wanted to show both band and inside—tough shot).

Thank you all, as ever!

 

Could be aventurine or could be dyed quartz - cheers

 

Thanks!

 

...or dyed howlite.

 

Hi spirit! Glad to see you here too.

I looked at howlite and it does resemble it. Although what I saw seems to have more pronounced inclusions.

The other question that occurs to me is what did they use to make them all stick together?

 

Hi,
There is that plastic that you heat to melt and pour. When it hardens again it glues everything together.

Thank you. That makes sense.

Do you personally have an idea about what the stones are?

 

Hi northern Yes howlite has veins but some is clear. Howlite is also dyed to mimic turquoise. I used a two part epoxy to glue my stones to the silver before I burnished the bezels to the stone for extra strength, so maybe that is a clear epoxy on that ring. Looks like a student project. The stones also look like the bag of stones you get for a fish aquarium.

 

Might be apatite

 

Apatite. Yes, thank you for that suggestion.

 

Its not apatite.

 

(But in costume jewelry?)

Don't confuse carnival prizes and gumball machine trinkets with costume jewelry

 

Nothern I dug up an apatite, mine is a yellow but it comes in all colors,its a crystal so that is why I said your stones were not apatite

 

Thank you, spirit. I have an apatite too, and you're right. It's a crystal.

 

I've seen low-quality apatite beads that are somewhat opaque like those in the OP's ring and are the same color. I agree that it's a crystal (I've got a 14K apatite ring). Since it's a costume ring, I thought low-quality apatite might be a possibility and mentioned it FWIW. Regardless of what it is the ring is, it's very pretty.

 

Thank you. I think it's pretty too. And I appreciate all input, the more the better.

This board rocks!

 

You know,I was thinking, and it usually gets me in trouble but I used to put broken turquoise and coral in bezels affixed with an epoxy and they looked like your ring. I would let the material harden, then I would grind the stones/coral flat to the bezel edge on a lapidary wheel. Maybe the maker of your ring planned that but never got around to it?

I was teaching my cousin silversmithing and she made these pieces. The truck to the right is turquoise and jet and the piece looked like yours before she used the grinding wheel.

 

Can remember seeing them with other big 'fashion rings' in department stores in the late '60s-early '70s (around the same time those gravel/crushed glass mosaic wall plaques were popular) - 'semi-precious pebble' pops into my head, but not really sure if my memory is accurate there. Have also seen cufflinks and pendants...
