The Estate Diamond Jewelry Team

Estate Diamond Jewelry has been operating in New York since 1980. Founded by Michael and Afshin in NYC, it has since flourished into a 5th Avenue showroom together with a thriving online presence.

Michael Khordipour

Michael KhordipourThe co-founder of Estate Diamond Jewelry and the owner of M. Khordipour Inc., Michael founded Estate Diamond Jewelry in 1980. Starting the business traveling in his car from customer to customer, Michael slowly grew his dream into the flourishing business that it is today. Known for his keen eye and his superior taste in fine jewelry, Michael has made it his focus to curate one of the top collections of vintage jewelry in the world.

Although Michael is passionate about all types of rare and fine jewelry, he soon realized that there were many customers who appreciated the vintage rings that he collected on the side. After a lot of convincing, he began to make them available for purchase.

Known for his positive attitude and compelling warmth, Michael is always on the laborious hunt for “the perfect ring”. He is extremely particular and carefully curates each ring that joins the collection. His pride in the direction that Estate Diamond Jewelry is heading is one of his most talked about conversations.

Afshin Shaddaie

From the very start of his career, he’s been passionate about rare antique jewelry. He enjoys a close friendship with some of the greatest antique collectors in the world. They usually turn to him when they stumble into their most difficult questions. He has since become one of the foremost antique jewelry experts in the world.

Each month, Afshin and Michael peruse through hundreds of vintage rings. They always study and analyze each ring very carefully. Afshin passionately tries to ensure that only the finest jewelry makes its way into the Estate Diamond Jewelry Collection.

Afshin is constantly traveling to international shows and private viewing events in hope to find new rare vintage rings that will be fine enough to make an impression. When he’s not traveling, he is available for appointments at our New York showroom. If you ever have a chance to have an appointment with Afshin, you will know right away how kind and patient he is.

He strongly feels that the rings in the collection are the best ambassadors of their own worth. He doesn’t believe in pushing or pressuring the visitors who visit the showroom. If someone is discerning enough to recognize the beauty and quality of any ring, then they’re the one who truly deserves to own it.
