H Dayan

Our story is one of a family legacy of jewelry excellence. H. Dayan & Co. is a high-end, family-owned diamond company located in Los Angeles and has been in business for over 45 years. Established by parents Haim and Helen, H. Dayan is known worldwide for its strong business relationships built and its transparency in business dealings. With a massive in-house diamond inventory, H. Dayan delivers high-end, custom jewelry in all shapes and styles to its clients - and most importantly at the best value.

We specialize in a wide range of products including loose diamonds, rough diamonds, fine jewelry, antique jewelry, and estate jewelry. Our family's passion for the jewelry business is evident in every piece we create and sell. 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. Our commitment to quality and customer satisfaction is unparalleled, and we strive to make every interaction with us a memorable one.
