Is agate jade? Many people often don't know the difference between agate and jade. Although they look very similar, agate and jade are essentially different. Do you know how good agate and jade are? What should we pay attention to when buying agate? Let's have a look
The difference between agate bracelet and jade bracelet
1. Jade is a broad concept, including jadeite, nephrite, Xiuyu, shuimozi and agate. Agate is very different from other kinds of jade. First of all, it is different in physical properties. The hardness of agate is 6.5-7 degrees, the refractive index is 1.53, and the density is 2.60/cm3. It presents glass luster in appearance, while the density of jadeite is about 3.33 g / cm3, and the refractive index is 1.66. Jadeite has a very bright glass luster, which is different from the glass luster of agate, Appears shiny and rigid; Nephrite (also known as Hotan jade) has a density of 2.95 g / cm3 and a refractive index of 1.606 -. 632. Nephrite is generally translucent, showing a kind of grease luster and so on.
2. Secondly, in terms of appearance, agate has a unique concentric ring banded pattern, which is circle by circle, while other kinds of jade do not have this concentric ring banded pattern structure, which is also one of the characteristics that can intuitively distinguish agate from other jade.
3. In terms of color, there are many colors of agate. As the saying goes, thousands of agates become 10000 kinds of jade, while other kinds of jade also have many colors, especially jadeite. However, the color of agate is very bright, gorgeous, evenly distributed, and the color bands are obvious, while other kinds of jade have no clear color bands.
Which is better, agate bracelet or jade bracelet
Compared with jade, agate must be more valuable than agate. However, according to the age level, young people suggest buying agate bracelets. If the age is a little older, they suggest buying jade bracelets.
Agate, also known as code agate, horse agate and horse brain, is a kind of chalcedony minerals. It is often a striped block mixed with Opal and cryptocrystalline quartz. Its hardness is 7-7.5 degrees, specific gravity is 2.65, and its color is quite hierarchical. Translucent or opaque.
Which is more expensive, agate bracelet or jade bracelet
Due to the abundant reserves of agate in the world, there are many agate accessories on the market. The price of agate is not very high. Generally speaking, an agate bracelet can be bought for hundreds or even tens of yuan, but the price of some agate varieties is also high, such as some high-quality black agates, which are not low. For example, Cartier often uses high-quality black agates for inlay. But the prices of other kinds of jade are also different. For example, jadeite and nephrite are generally higher than agate, but the quality of jadeite and nephrite is different, and their prices are also different. For example, high-quality jadeite, such as glass jadeite bracelet, can cost millions, but bean jadeite Pendant with poor quality can be bought for hundreds of yuan, Even a few tens of yuan can be bought. The same is true for nephrite. The price of high-quality lanolin white Hotan jade seed material can be as high as millions, but some ordinary sapphire can be as high as one or two hundred yuan. The price of some other kinds of jade, such as Xiuyu and shuimozi, is not very high, just like agate.
Therefore, in terms of price, we cannot make horizontal comparison between different types of jade, but should make vertical comparison according to the quality of jade in the same type.
