Sterling Silver Mexico Peacock Bird Abalone Brooch Pin

I think this to be a peacock with abalone set in sterling silver. Measures just shy of 2 inches in length by 3/4 of an inch wide. Has all kinds of stamping on the underside which a lot of it is not readable for me to make out to list here. Older vintage piece that does show its age some as there is some cracking in the abalone in a few different places. And it almost looks to me like a tiny piece has chipped out from its beak area and also in the neck area. Still quite a beautiful brooch for sure even with its flaws. Remind me about taking a back picture of this so you can see those markings if your interested. Estate purchase.
