I tried to get this beautiful piece authenticated through legitgrails site and this is the response I got back. I have searched and searched and only coming up with it could have been a runway piece. Any help confirming would be amazing.

Ammonia, regular old cleanimg Ammonia on a q tip. Household stuff.

It is what's reactive in the polish when applied to phenolic compound. Bakelite is a brand name of phenolic resin. Bakelite as a company the og company focused on more industrial uses. Radios Gaskets Parts MachiningStuff etc Catalin, marbelette and others formulated the jewelry tones and special finishes of phenolic resin. There's a seller on Etsy that sells bakelite testing pads. These are genius. They are cosmetic pads soaked in super secret ..Ammonia allowed to dry and become portable for on the run testing. Follow me for more cool tricks.

Do you recognize anything about this beautiful brooch? I need some help. It’s not marked. AI is useless, you know that. The turquoise high dome cabs I believe are plastic and not glass. It’s really hard to tell because it has a bit of a ting when I tap it….. but not quite right to me to call them glass. Can you help me? Give me any thoughts you may have. Thanks!
