Featured Silver, glass & gemstone earrings

These were in a pile of costume jewellery and they are as in the pink stones test as glass.
The centre gem tests as quartz and the others as Chrysoberyl,spinel or topaz (Don’t know if to believe Mary on that or if so which)
The metal tests as silver but unmarked. I did wonder if they started life as buttons and have had the shank cut off?
The gems are all set with the metal having been pulled over the edges of them to keep them secure ( is there a name for that?) and the gems are all rough cut, more chunks than faceted.
The pink have a faint manganese glow under UV.
Any ideas? Putting my neck on the line could they be AH?

Thanks for looking

 

That's a big YUP on the buttons. An old name for setting stones that way was "gypsy-set", probably politically incorrect now. Rock crystal is a good possibility for the clear stones, but I have to wonder about the pink ones.... They all look the same color, but are they all faceted the same way?

 

The pink are all faceted the same with a small central table. The colourless ones are chunks.

 

The solder and cut off peg are part of the center stone setting. The stones are bezel set.

 

Rub over mount.

White stones could also be zircons, these also test around the same on the thermo meter.

I guess they could have been buttons, the gemstones would be unusual for this tough. The metal 'stud' showing on the back is the rivet end for the central mount and the soldering could be original to stop rotation, hard to say for sure I guess.

 

Clip style is 50s ish, so I'd think not AH. Jolly nice.

@Any Jewelry ? They don't look European.

 

AJ is on fire as always! Thankyou @Any Jewelry
These are Indonesian, Javanese to be precise so I was way out with AH!
Apparently they would have had studs on the back before being converted to clips.
White stones are most likely Zircons as Ce BCA suggested.
Like these-

 

Found some the same! Shame mine have been butchered but still.

I now need to go book shopping!

 

They may not be original now, but they're way more wearable.
