Brothers Avi and Joey grew up in the jewelry business alongside their parents learning the tricks of the trade at a young age. Today, they carry the same passion for honest, transparent business dealings and hope to make it easier for clients to get access to the world’s rarest and most beautiful diamonds at a rate and quality they can trust. The H. Dayan diamond jewelry showroom is available by appointment only at its Beverly Hills location; however, clients from around the world can still purchase jewelry remotely via virtual consultation and video chat.
