The main chemical composition of agate is silicon dioxide, or timely, which is one of the mineral gems, also called timely jade. The main component of jadeite is metal silicate inorganic matter. There are two kinds of jade: soft and hard. Usually, jade refers to nephrite. It belongs to one of the most common jewels. The mineral commonly known as jadeite is mainly jadeite, and the three main substances that make up jadeite are silica, alumina and sodium oxide.
What's the difference between agate and jadeite?
1, texture
Agate is a kind of chalcedony, which belongs to an unfinished crystal mineral. White stone and aphanitic are often flaky, with hardness of 6.5-7 degrees, density of 2.6-2.7 and refractive index of 1.53- 1.54. Agate is a kind of crystal gem with good transparency and fine particles, which is difficult to carve, but it can carve very fine lines.
Jed. Jadeite and nephrite are molding minerals with poor light transmittance, but they are easy to carve. Jadeite is a kind of aggregate composed of many minerals. Its main component is jadeite, or it contains diopside, amphibole and sodium chromate. The hardness is 7, the density is 3.25-3.4 and the refractive index is about 1.66. As jade.
Step 2 color
Agate is very bright and colorful, with different shapes, obvious ribbons and uniform distribution. You can see concentric circles, ripples, layers or parallel stripes composed of different colors such as gray, white, red, green, light brown and light blue from the section. The color of jade is usually simple. The same piece of jade has only one or two colors.
