A roughly 3.5-kilogram chunk of rare Romanian amber, later valued at about €1 million or $1.1 million, spent decades propping open a door in a home connected to the village of Colți in Buzău County before experts identified it as the largest known specimen of its kind.
The elderly woman who found the dark reddish stone in a local stream bed used it as a doorstop for many years without knowing its nature. She died in 1991. A relative later recognized the object’s potential and arranged for its evaluation. Specialists at the Museum of History in Kraków, Poland, confirmed it as rumanite, a distinctive fossilized tree resin unique to the Buzău region and dated between 38.5 and 70 million years old.
Romanian authorities classified the piece as a national treasure. It is now held in the collection of the Buzău County Museum in the city of Buzău, where it has been on display since around 2022 after earlier exhibition at the Colți Amber Museum, an external section of the county institution.
The stone weighs between 3,450 and 3,480 grams according to museum records. Colți sits in the foothills of the Curvature Carpathians, an area long known for amber deposits in sandstone linked to the Buzău River system. Local collecting and small-scale mining of the material, known regionally as chihlimbar and scientifically as rumanite, date back at least to the 1920s. Rumanite is prized for its deep red, brown and near-black hues that can appear in more than 160 shades, setting it apart from the more common golden Baltic amber.
In 1991, the same year the woman died, burglars entered the home and stole jewellery, including a silver necklace in one account. They reportedly kicked the heavy stone, leaving a small chip, but left it behind. Around 1998 to 1999 the heiress, identified in reports as Elena Mușatescu, approached the Buzău County Museum and offered to sell the piece. The state acquired it and sent it to Kraków for authentication before declaring it a protected national asset.
Daniel Costache, director of the Buzău County Museum, has described the find as one of the largest pieces of its type in the world. “Its discovery represents a great significance both at a scientific level and at a museum level,” Costache told El País in 2024. He has noted that while market estimates place the value near €1 million, the scientific and cultural worth is incalculable.
In late August 2024 the World Record Academy listed the nugget as the world’s largest rumanite amber specimen. International attention increased after the El País report in early September 2024, with the story recirculating in subsequent years through scientific and general news outlets.
The Buzău County Museum maintains the piece at its main site on Aleea Castanilor in Buzău. The Colți Amber Museum, housed in a traditional-style building in the village, focuses on the region’s amber heritage, including raw and processed samples, jewellery and related ethnographic material. Museum officials have released images of the irregular, dark reddish nugget for public use.
Large intact specimens of rumanite remain rare. The object’s size and age make it a significant example of fossilized resin from forests that once covered the area during the late Cretaceous to early Paleogene periods. Primary confirmation of the details rests on statements from the Buzău County Museum and the Polish laboratory analysis cited across reporting.
