Key Difference – Aventurine vs Jade
Aventurine and jade are two green colored gemstones that may confuse some people. Aventurine is a variety of quartz which contains small Mica, Hematite or Goethite. Jade is the gemstone name given for two different minerals Nephrite and Jadeite. This is the key difference between Aventurine and Jade. Sometimes, aventurine is also known as Indian jade or Australian jade, but it is not considered as a form of jade.
What is Aventurine?
Aventurine is a form of Quartz / Chalcedony, which contains small included flakes or scales that give it a shiny effect. Aventurines are usually green in color, but, they can also be found in colors like gray, blue, orange, yellow and brown. The green colored aventurines get their color from Fuschite, a chromium-rich variety of Mucovite. This green can range from a light green to a dark green. The brown and orange colors are attributed to hematite or goethite.
The shimmering or glittering effect of Aventurine is known as aventurescence. The intensity of this effect depends on the size and density of the inclusions. These inclusions are often Muscovite mica, Hematite or Goethite.
Aventurine is used as a minor stone for jewelry. They are fashioned into cabochons or beads and used for necklaces and bracelets. Aventurines are commonly found in India, Brazil, Austria, Russia and Tanzania.
What is Jade?
Jade is an ornamental stone. This stone is usually green in color; the color can vary from light green to dark green. Deeper green colors are valuable. Jade is the gemstone name given for two different mineral forms, Nephrite and Jadeite. Since both these minerals have similar appearance and properties, no distinction was made between the two different types of Jade until modern times.
Nephrite is generally green, cream or white in color. It is composed of extremely dense mineral fibers that are interlocked and very tough. It is softer and more prone to scratches than Jadeite. Nephrite is also the more common of the two. Nephrite jade comes from China, Brazil, Russia, and the United States.
Jadeite is the rarer of the two and comes from Burma, Tibet, Russia, Kazakhstan, and Guatemala. Jadeite is not as dense as Nephrite and is more prone to chipping.
Jade has been an important gemstone in the past, especially in the Chinese culture. Jade is often used in jewelry such as necklaces, bracelets, earrings, and rings. It is also used in ornamental figurines, especially Buddha statues, and animals.

For us nonprofessional (amateurs) but frequent purchasers of real gemstones but willing to find deals outside of hi marked up store front specialized jewelry stores (wholesale centers not located in too many regions and often limited to licensed vendors), it would be nice if you could prove closer views so we can see for ourselves the particular patterns of inclusions or other interior markings which, for example, separates finished for jewelry Jadeite from Aventurine. Often quartz can be treated to look like jade or other more expensive stones on the surface. But the real test is beneath the polished surface. I have a light green round polished necklace but I can’t tell if it is Jadeite or a good quality Aventurine looking like Jadeite. Paying in a costly city as San Francisco a fee of no less than $50. just for one item appraisal may cost more than the original price if that necklace is just Aventurine. I have other real gemstones like that.
