ridacna (硨磲)
Tridacna is the largest marine shell, with a diameter that can reach up to 1.8 meters. The name "Tridacna" originated during the Han Dynasty, due to the radiating grooves on its surface, which resemble ancient cart tracks, hence the name "车渠" (Chēqú). Later, the name was modified to include the word "stone" (石), since its shell is as hard as stone. Tridacna, along with pearls, coral, and amber, is considered one of the four organic gemstones in the West. In Chinese Buddhism, it is regarded as one of the Seven Treasures, alongside gold, silver, glass, agate, coral, and pearls.
