Vintage 925 Cuff Bracelet White turquoise? White agate?

PRICE IS FIRM NOW. Thank you!!
Super cool vintage sterling silver feather/leaf adjustable cuff bracelet with what I believe is a white Buffalo turquoise stone, but honestly I don’t know. Perhaps white agate? It is such a unique white stone. Has a very shiny finish. Interesting webbing. stamped “Hecho en Mexico 925”. Pretty heavy at 19.7 grams, almost an ounce! I’ve had a lot of these cuffs but I have never seen a white one like this! Perfect for any collector of southwestern, Native American Indian, old pawn, squash blossom, boho, antique, QT, jewelry!
