It’s In The Family

Founded in 1966 by Ivan Vortouni and his wife Vivienne, the then young jeweller was brimming with a passion for quality and unique stones. Ivan rapidly built the business to be renowned for its world class collection of opals and unique custom-made jewels that were true statement pieces.

We now take this history and family values in a renewed creative direction at Giulians, with the mission of making finely crafted, completely unique jewellery with the most personal, white-glove customer service you will experience in the industry.

Free worldwide shipping and free international returns.

Every piece is hand-crafted by our master jewellers and completely unique. You own the only one.
