Find Rare Treasures from Around the World
The history of a country, culture and people can often be best told through its art. Marie Betteley’s mission is to curate the most rare, historic and exquisitely crafted antique and vintage jewelry and treasures from Russia, France, England, and other storied locations, and bring them to you.
Marie is an expert gemologist and leading authority of Russian jewels and consults for auction houses, museums and private collectors worldwide. Her eye for beauty, knowledge of antique and vintage pieces and the fascinating stories behind them; along with her experience as a lecturer, arts tour guide and author; provide sound assurance of the authenticity of each piece you purchase – and that it will be carefully packaged and delivered ready to be admired or worn and celebrated by you and/or your loved ones.
It is our joy and pleasure to help you find the rare, antique or vintage piece of jewelry or treasure that sparks your interest, peaks your curiosity and appeals to your taste.

Frequently Asked Questions
How did you get into the business of trading in jewels and treasures?
I grew up in Europe and got hooked on the beauty and mystery of historic treasures at an early age, with many castle visits in Germany and shopping for antiques with my parents in France. My mother studied gemology and I was intrigued by precious gemstones as a teenager, and decided to become a gemologist in my early 20s. Living on the grounds a Hillwood Museum in Washington DC also increased my interest, as did working at Christie’s auction house in New York for 10 years.
Do you buy and sell treasures directly or as a consultant?
I do both. I tend to buy a few exceptional items a year usually from private clients. If I don’t choose to buy a single item or a collection but have potential buyers in mind, I sometimes offer to arrange sales on commission basis. Unlike public auctions all transactions are kept confidential. With 35 years of experience as a private dealer I’ve cultivated an extensive global network of clients.
Why choose Marie Betteley when selling over auctions?
Unlike the long wait time, uncertain outcome and hefty fees auction houses charge sellers, the price I offer as a private dealer is immediate, net to you and competitive.
How do you source your selection of jewels?
In the past most of my best finds have come from European countries and Great Britain but sometimes incredible treasures surface in North America. I buy directly from the public and occasionally at auctions and from dealers. In 2026 I will relocate to Europe to expand my jewelry and tours business there while maintaining a base in New York City.
Where can I find items to buy on your website?
Our Treasures page features a small selection of exceptional objects and jewelry. Each item is thoroughly researched for authenticity and provenance (history of ownership). Each gem and precious metal is tested using gemological equipment. If you have any questions we encourage you to call or text us on WhatsApp at +1 917 319 5736.
How can I find out more about Imperial Russian Jewelry?
That’s our specialty. We have a podcast which was featured in Jewelry Journey, hosted by the marvelous Sharon Berman. For more extensive information on the history and market of Russian jewelry firms, our groundbreaking book Beyond Fabergé: Imperial Russian Jewelry (2020) is available for purchase. To learn more, go Beyond Fabergé page. My jewelry blog in part covers the topic of Russian imperial jewelry and Romanov history.
I’d rather experience first-hand rare jewels and treasures, rather than acquire them. What do you suggest?
