Lapis lazuli is a relatively common jewelry, players most often hear is "new material" and "old material" to distinguish between good and bad lapis lazuli, today we will take a look at why old material lapis lazuli is better than new material.
The three pieces on the left are old materials, and the one on the right side are new materials
As shown in Figure 1, if you look at the rough, the "new material" and the "old material" are very well distinguished, and the "new material" can only take the thin blue part of the sandwich to make the goods, and the particles are coarser, usually only the brand and smaller beads, once the thickness of the goods is large, you can see the obvious "golden and white" layering. Because the finished products of the new material are far more on the market than the old materials, the industry has also given the color of the new material a domineering name "Emperor Qing" to raise the value, in fact, because the new material lapis lazuli has not been fully baptized by high temperature and pressure in the formation process, the mineral components are not fully integrated, and the color is more dull, so do not be intimidated by the name "Emperor Qing".
Ordinary old material
The color of the old material is much richer, from denim blue to cornflower blue to purple flare, attracting many "lustful people" to pursue lapis lazuli old material.
Fine old materials
Best Old Material (Madan No. 4 Pit)
"Old material" rough can be used parts are also more, but the quality between the old materials is also a big difference, not much to say directly look at the picture, the better the material, the higher the delicacy and purity, the richer the color, you can get "no white and no gold" goods, so the gram gap between the finished lapis lazuli products can reach a hundred times.
Comparison of three qualities
Old rough
Of course, new materials also have fine products, and they may not blindly pursue old materials.
The new material has no white and no gold shell, but I personally feel that the color is not as flexible as the old material
