Hello, I'm an expert in the field of gemology with a particular interest in the study of jade. Let's delve into the distinctions between jade and jadeite, two varieties of what is commonly referred to as jade.
Jade is a term that encompasses two different minerals: nephrite and jadeite. These two minerals share some aesthetic similarities, which is why they are often grouped under the umbrella term "jade," but they are indeed distinct from one another in several key ways.
Nephrite is the more common of the two and has been used for thousands of years, particularly in Chinese culture. It is a tough, compact variety of actinolite, which is part of the amphibole group of minerals. Nephrite is known for its toughness and resistance to breaking, which has made it an ideal material for carving intricate designs and figures. Its chemical composition is primarily of calcium and magnesium silicate hydroxide, and it has a density that ranges from 2.9 to 3.1 g/cm³. Nephrite's hardness on the Mohs scale is between 6 to 6.5, which makes it suitable for use in jewelry and ornamental objects. Its crystal structure is characterized by its fibrous and compact nature, which contributes to its durability.
Jadeite, on the other hand, is a member of the pyroxene group and is considered to be the rarer and more valuable of the two. It is particularly prized for its vibrant colors, which can range from a pale green to an intense emerald green, and it can also be found in lavender, pink, and white hues. Jadeite's chemical composition consists mainly of sodium and aluminum silicate. It has a higher density, typically between 3.3 and 3.5 g/cm³, and a slightly higher hardness on the Mohs scale, ranging from 6.5 to 7. Its crystal structure is more granular and less fibrous compared to nephrite, which can make it more brittle in some cases.
When it comes to origins, nephrite can be found in various locations around the world, including China, which is often associated with the "classic jade" of historical and cultural significance. Jadeite, however, is predominantly sourced from Myanmar (formerly known as Burma) and is known for its higher value and rarity.
In the marketplace, jadeite is often more expensive due to its scarcity and the vibrant colors that are highly sought after by collectors and connoisseurs. Nephrite, while still valuable, is more commonly found and thus typically less expensive.
Identifying the two can be challenging without specialized tools, but there are some visual cues. Jadeite tends to have a more vibrant and translucent appearance, while nephrite is often more opaque and has a more subtle luster.
Caring for jade involves similar practices for both types, including avoiding extreme temperatures and chemicals that could damage the stone. However, because of its slightly higher hardness, jadeite may be more resistant to everyday wear and tear.
In conclusion, while both nephrite and jadeite are referred to as jade, they are unique minerals with different properties that make them distinct from one another. Understanding these differences is crucial for collectors, jewelers, and anyone interested in the beauty and history of these fascinating stones.

Jadeite and nephrite are totally different minerals. They have different densities, different hardness, different crystal structure, and different chemical compositions. Classic jade, the jade that comes from China, is nephrite, and jadeite, the rarer type of jade, comes from Burma.
