My mom has had this belt buckle made from a fairly big looking chunk of turquoise for a while now and asked me to see if I could find anything out about it. Its about 3 3/4" long by maybe 2ish wide, and ranges from maybe a quarter to a half inch thick. The metal part of the buckle doesn’t seem like pure silver, maybe some kind of an alloy? I would think it would show some more significant tarnish if it were mostly silver.
The bottom has a bit of a void in it that has a fill of some sort, it seems to extend under the metal a little bit. There’s what looks like a letter D carved into the stone, and there’s a small mark in front of the hook for the buckle that might just be a ding in the metal. Its sort of a seafoam greenish color, with some veining that looks like a straw or pale gold color in a pattern that almost resembles snake or lizard skin at what’s probably the thickest part.
I tried to make the pictures as accurate as possible, but the color isn’t quite right.
Any information I could get on where this might have come from and/or what kind of value it might have other than sentimental would be appreciated.
