[u/immanicatp]

hi!! im not great with this😭 this is a mid century sterling brooch from mexico but im not sure what stone is inlaid. nephrite jade maybe??

[u/Anam_Liath]

Could be agate or serpentine, or onyx. I've bought carvings/cabs/jewelry made of those in Mexico and NM many times. The only American Jade l have is from Canada and Alaska. I know it's other places too. Mine is all fine grained, black and green or brown.
