Diamonds are natural gemstones formed under the conditions of high temperature and high pressure deep in the earth. Through some knowledge of diamond knowledge, we know that diamond has the characteristics of high hardness, high refractive index and high dispersion rate, and its melting point also reaches 3550°C-4000°C, so can diamond be burned with fire? …

Many people know that the formation of rough diamonds takes more than one billion years, and a rough-looking rough diamond needs to go through complicated cutting and polishing to turn into a diamond with a beautiful appearance. Today we will reveal the secret of the cosmetic procedure of a rough diamond. Planning and marking is …
The visual identificSince the outbreak of the epidemic, there have been several obvious changes in the international diamond market: 1.The downstream of the industry (retail) first declined and then increased, directly affecting the midstream (processing industry) and upstream (mining) of the industry; 2.The market in the post-epidemic era has developed rapidly, helping the midstream and …
The visual identification of rough diamonds Manpower from the following aspects: (1) Observe the gloss Because diamonds have a special diamond luster, the refractive index of diamonds is as high as 2.417. There are few natural gemstones with a refractive index as high as mineral oil. The rough diamonds can see strong luster even on …
Lab-grown diamonds rough are known by several different names, including synthetic diamonds rough, man-made diamonds rough, and cultured diamonds . They have the same physical properties of natural diamonds rough because they are created in a lab using technology that replicates the natural diamond rough growing process. Rather than taking billions of years to form …

While they may look similar, diamond simulants (like cubic zirconia) are chemically not diamonds at all. They’re completely different gems and materials. On the other hand, lab-grown diamonds are chemically the same as natural diamonds, but their creation process is sped up by science. What is a simulated diamond? Diamond simulants and lab-created diamonds often …
