Worth an estimated PLN 140,000 (EUR 29,803) the piece was officially weighed and measured at the city's Museum of Amber to mark World Amber Day. It will now enter the Guinness of Book of Records.
The art pieces include an amber craftsman’s house, the first art piece in the world manufactured in a 1:6 scale with figures and elements of the interior entirely 3D printed.
The collection presented at the Museum of Gdańsk includes previously unknown species and the world’s largest species of venomous-fanged mygalomorphae spider to be found in Baltic amber.
The amber is thought to have been dislodged during dredging work ahead of building a 1,300-metre canal in an area known as the Vistula Spit.
The rare set, of which there are only four in the world, came with a hefty price tag: the museum bought it for around 2.4 million złoty (over 0.5 million euros).
With the cost of amber reaching as much as PLN 20,000 for 1 kilogram, the 6.9-tonne deposit would be worth as much as PLN 138 million.
Tomasz Ołdziejewski from the village of Szutowo on the Baltic coast, spent a month building his massive 1.5-metre-long replica of the Titanic ship to pay tribute to those who lost their lives in the tragic event which saw it sinking after hitting an iceberg.
During this year's event, exhibitors will present jewellery, watches, unmounted precious stones, jewellery equipment and protection systems, among others.
Estimates from the Polish Geological Institute show that between five and six tons of amber is found on the Baltic coast ever year, compared to just 1 ton extracted from underground deposits.
