Weingrill
Carlo Weingrill set up a goldsmith workshop in Verona Italy in 1879. His quality of craftsmanship and design was recognized by Cartier and they were enlisted to create the Trinity bandles for them. Tiffany and Company noticed as well and gold cuffs and bracelets were created until Weingrill created the tubogas designs for Bulgari. The firm passed from generation to generation until the fourth generation of Weingrill took over headed by Carlofilippo.
