Featured Two brooches for your opinions

Hello again,
Hope these pictures turn out. Two brooches for you amazing jewellery wizards.
Wondering if the first is jade (no markings at all but heavy piece)
Is the second costume? It is base metal...but the glass, crystal ? is very cold and etched to the front surface. I can see no air bubbles and am not sure what the small ? stones are. I thought immediately cheap costume..but it seems so well made I'm once again confused. Help please.

 

I think the first one is very interesting, but I don't know anything about it. I can't tell if those things are stone or ceramic, but I'll bet they're really old. Maybe originally buttons? How big are they?

 

Thank you..I do feel confident that they are not ceramic..but..don't know any thing else.
Entire brooch is about 2 inches long

 

These are Chinese carved "jade". Jade being used loosely as there are many stones identified as "jade".
Whats odd is the marquisites. This may be something that was remade into a bar pin.

 

I'm having a hard time seeing the second pin.
Is there any color to the stones? Light pink maybe?
Might be quartz.

 

Both are what I think of as good costume, judging by photos. Going by pieces I have seen & one I own, I have the impression that some makers of better costume pieces would import carved stones from Asia - guessing China, but I don't know for sure - for use in their own designs. I have a silver brooch by American maker Walter Lampl that incorporates an amethyst carved as a plum, & have seen other pieces that used a carved 'jade' element similar to these. They may not be true jade of any type, possibly dyed chalcedony, but still stone & carved rather than glass & molded. If molded, would expect that even if the swirls of color differed in all 3, lines & perforations would be the same. As well as I can compare, these are each different. Lampl jewelry seems always to have been marked, but your brooch, with its deco touch of marcasite circles at either end, feels like it is from the same period.

I can only say about the other brooch that it looks very well made & suspect it catches the light nicely?

 

I strongly suspect rock crystal in the second one.

 

very interesting Bob...!!!

 

I've jade and marcasite pieces both original Art Deco ones and later. That brooch is later: at least 1950s with that back. Probably silver, they usually are. The rock crystal one is 1920s or earlier.

 

Those carved jades, etc were made in China and exported to other parts of the world to be set in jewellery. Hugely popular during the Art Deco period, but as Obb said, this one is later.

 

clear, clear no ting of colour that I can see

 

Once again I am in your debt..thank you so much.
I am most surprised with the rock crystal. It felt very cold so I thought perhaps..but the base metal threw me off.
Thanks again
