Divers never dreamed of such a treasure; 4000-year-old ship surprises researchers with black gold of Stone Age

No matter how many new technologies man has invented, the bottom of the ocean is a treasure trove that is still mysteriously hidden from us. Many ships have sunk into the depths of the sea. One of the most significant among them is the Titanic. The Titanic is yet to be properly studied in detail. Similarly, thousands of ships are still in the ocean. Researchers and marine team are still trying to find their remains.

A 4,000-year-old shipwreck has now been found in Italy. A rare stone called Obsidian, often referred to as the "black gold of the Stone Age," was also found in this ship. The wrecked ship was found 130 feet below sea level by the underwater unit of the Naples Police in Italy.

The shipwreck is near the White Grotto (Grotta Bianca) sea cave in Capri, Italy. Obsidian gold, a purple-black volcanic glass, was discovered in these remains. It is reported to weigh around eight kilograms.

According to experts, obsidian is a fabulous and unique stone that has long been used to make cutting tools. It is often referred to as the black gold of the Stone Age. Obsidian is formed by the rapid freezing of lava. Its texture is smooth and is said to be a protective gem. 'Black Gold' is very popular in the stone market and its value is very high.

Researchers also plan to find the San Jose Galleon, a Spanish ship that sank in the Caribbean in 1708 during a battle with the British navy. The ship is believed to have treasure worth $16 billion.
