Joseph DuMouchelle has more than 30 years of expertise

in the buying, selling and appraisal of signed jewelry, important diamonds, colored stones and art works.  In that time, we have established ourselves as one of the top buyers and sellers in the industry, and we are known for our integrity and a fierce commitment to our clients.

But the tradition goes back even further, starting in 1927, when Joseph DuMouchelle’s grandfather founded DuMouchelle Art Gallery, an auction house and gallery in Detroit, Michigan. Since then, the DuMouchelle name has been synonymous with estate transactions, procuring estate sales and purchases worldwide. Located in an historic building in the city’s downtown district, the gallery is one of the oldest U.S.-founded auction houses. It has sold a wide array of valuable art work, furniture, objects and collectibles, including from paintings by Picasso and Monet, Louis XIV chairs, vintage Rolls Royce cars, Georg Jensen silverware and rock memorabilia.

Now in the fourth generation

Joseph DuMouchelle is proud to carry on the family legacy. After working with his family for 10 years, Joseph set out to launch his own estate practice, with his partner and wife Melinda Adducci, focusing on the buying, selling and appraising of fine jewelry, objects and art through private sale, private brokerage and auction. After opening their flagship salon in Grosse Pointe Farms, Michigan, Joseph and Melinda opened a second location in Palm Beach, Florida in 2008 and another location on Fifth Avenue in New York in 2009.



Through their three office locations and frequent travels around the world

Joseph and Melinda have worked with private clients, collectors, banks, lawyers, estate executors, curators, other expert appraisers and a cachet of buyers and sellers to handle a vast number of fine jewelry and other collectible, highly valuable objects.

Among Joseph DuMouchelle’s most exciting finds are Matilda Dodge Wilson’s estate, a selection of items from legendary entertainer Nat King Cole’s estate, and the 7.45-carat Harry Winston diamond engagement ring that Donald Trump gave to his ex-wife, Marla Maples.
