Aventurine, also known as "ocean stone" or "dongling stone", also known as "dongling stone" or "Indian jade", is geologically referred to as chromite bearing oil green quartzite, with a beautiful color. Nowadays, people collectively refer to all brightly colored, dense and tough quartzite or secondary quartz in the earth's crust as "Dongling stone".

Dongling jade is a type of quartz ore, similar to Huanglong jade, with a chemical composition of silicon oxide. It has no fixed shape and usually comes in colors such as green, yellow, pink, red, white, blue, etc. Green is the most common, while emerald green to emerald green is of the highest quality. Quartz ore was originally colorless and pure white. During its long formation process, it contained other substances and trace elements, presenting a series of attractive colors and special optical phenomena, and became the beloved Dongling jade.

Dongling stone is mostly opaque, with occasional parts being slightly translucent, and its hardness is similar to that of crystal. The scientific name is sand and stone, and it is also a member of the crystal family. Its contents usually include microcrystals, pyrite, etc. So, there are often transparent or reflective points appearing on the stone surface.
