Here I show you two little brooches and a stickpin. Very nice but please have you any idea how to see the difference between French yet (black glass) and real yet? There is also Vulcanite but this has always a black brownish color and these three are real black. I know one of those differences is the temperature because glass always feel cold and perhaps a difference in weight?
These three are about the same width.; bow-shaped 5.5 cm, middle one 4.5 cm and the stickpin also 4,5 cm. The weight of the bow-shaped brooch is 6 grams, the middle brooch on the photograp is 5 grams and the stickpin only 3 grams. I must add that the bow-shoped brooch seems to be a little duller black than the other two.
Again my question: what period please and what kind of material?
French jet is more shiny than real jet. And you are right about the weight: real jet is light and french jet is more heavy. But as they all have different forms, its hard to tell by weight. I can't really tell from your pictures though I believe the one in the back looks less shiny than the one in the front (the jet that is, not looking at the rhinestones).
Thanks Newtimes for your comment Idon't still not know for sure but you are right it is quite difficult
It's hard to tell without touching, but the one on the bottom with rhinestones could be celluloid, and it was probably made in the 20s or 40s, so I'd call it Art Deco, not mourning jewelry. If the two brooches on top have any chips, those would look different (under magnification) on jet and glass. For me, the best way to tell the difference is by handling the pieces. Perhaps, if there is a store near you that sells verified jet pieces, you may ask to touch them and weigh them in your hand.
A good advise davyd286 I will look for a shop, thanks!
Newtimes and davyd286, in my further search for the material from which these brooches are made I came to the discovery, after the Simichrome test that the middle brooch (photo) is made of Bakelite.
Well look at that. When I try the simichrome test, it never works on black pieces.
I guess now you know all of them.
The middle one is bakelite, the one on top probably is real jet and the one in the bottom looks like celluloid.
Newtimes, thanks for your helpful comment. I didn't think on a Simichrome test in the first place. But when I looked at Google pictures for black Bakelite brooches I saw a lot. Well that give me the idea to try. I have some black necklaces I will try Simichrome too.
