Susan and the Griffin

The griffin—part lion, part eagle—stands as a symbol of supreme authority and guardianship in mythology, mirroring our commitment to craftsmanship in fine jewelry.

Each piece of jewelry we create is imbued with our logo and the griffin’s virtues of strength and vigilance, ensuring that our designs are a symbol of heritage and excellence.
