Rhinestone brooch ID? Who? When?

About 2 1/2" tall, 1 1/2" across. I confess I'm a sucker for those fancy shaped and textured stones.





With a little help, a missing rhinestone was replaced, but I'm not saying which one.

 

Molded glass. The ones in the middle look like sabrina rhinestones - pretty sweet. This could have been made by a lot of companies.

 

I have no doubt that the stones in this are anything other than glass. I just find those leafy things a pleasant diversion from the usual facets. Sabrina glass because of the frosting? Frosted givre glass? Frosted Cuba rhinestone. Mixed color stones really seem to be a bit of a minefield.

 

Sabrinas are frosted on the ends and the middle, where the color is, should be transparent. Givres are the opposite. Cubas are two-tone with the second color in the center, but the whole thing is clear.

 

Thanks for that, but... these stones really don't fit any of those definitions, do they? Those two center stones are 2-toned and frosted over the entire surface. Maybe I should invent a name. Butterscotch Ripple stones?

Maybe it's the frosting that makes these different. Maybe the definition would be a cinch without the frosting. I can see how transparent and opaque glass might both be present in a rhinestone, that would be difficult enough, but to selectively frost the surface? I think that would be very difficult to manage economically and would require very precise control of the colors.

This site has stones they call frosted Cubas, but maybe that's just them:

For givre and sabrinas, the effect is internal. I probably used the wrong term.
