Vtg Brutalist Black Leather Crossbody Purse with Brass and Gemstones Carvalhu?

Vtg Brutalist Black Leather Crossbody Purse with Brass and Gemstones Carvalhu? This leather bag is in very good condition. It is possibly the brand Carvalhu from Brazil. There are no tags or markings so I cannot be 100% certain. The gemstones of Amethyst, Rock Crystal and Smoky Quartz are all in good condition and securely attached to the brass. It measures 9" across, 8" in height, 27.5" strap drop. (quite long) From a smoke free home.
