vintage Murano art glass bowl, millefiori confetti multi colors silver flake on black glass

Handmade free form art glass bowl, not marked or signed that we could see. We believe this is probably a Murano piece, mid-century vintage?

This measures about 10 1/2" x 7 1/2" overall and is in very nice condition... minimal scratching to the bottom, interior nice and glossy, no chips or cracks.
