Domestic sapphire quality analysis
Many people may not know that China is also one of the major producers of sapphire in the world. China's sapphire is not famous for its quality, because of its poor quality, has not been able to walk in the ranks of the world's high-end sapphire. However, I have produced a lot of sapphire, and the production of sapphire in Shandong Changle is the most prominent. Other places where I have passed sapphire are: Heilongjiang, Hainan, Jiangsu, Fujian and other places. Let us introduce you one by one. The sapphire features of Hainan and Fujian are similar. Most of the colors are pure and the transparency is high, but the particles are small. Occasionally, the sapphire with larger particles is surrounded by a layer of white opaque ring. The sapphire produced in Jiangsu is more colorful and the transparency can reach the gem level. Unfortunately, there are too many internal cracks in the gemstone, and the sapphire with large particles and high clarity is rare. The sapphire produced in Heilongjiang is characterized by a small inclusion and a very positive color, but the production of large particles of gems is almost non-existent. The final Shandong Changle sapphire is the best quality in domestic sapphire. The color is slightly deeper and the other qualities are excellent.
