When you heard that Chinese people like jade for thousands of years, in fact, there is no place in China for production. Will it be a bit shocking? To be honest, in the gem of the world today, the dynasty of the dynasty is not a big name. Many people are used to going abroad to jewellery, and even like to go to the country of origin. In fact, it may not be good. If you have a long history, you will not be sure that the gems are true, or the certificate is true. Gems, China is also there, but you may not know it. China really does not only produce Hetian jade! There are still many quality stones. Hebei Zhangjiakou Peridot Olivine is known as the emerald at dusk and enjoys a good reputation in the international market. The olivine green is slightly yellowish, bright and not thick, beautiful and not delicate, giving people a simple, soft, intimate and natural beauty, which is loved by many simple and pure ladies. As an olivine, it must have three characteristics: color positive, pure color and strong color. The three complement each other and are indispensable.

Among them, the quality of sapphire in Shandong Changle is the best. The crystal has a hexagonal barrel shape and a large particle size, generally above 1 cm, and the largest can reach several thousand carats. Due to its high iron content, sapphire is mostly indigo, blue, green and yellow near carbon black, mainly indigo. There are very few inclusions in gem-quality sapphires. In addition to the black solid inclusions, fingerprint-like inclusions are still visible. There are no silky rutile and diffuse liquid inclusions. The flat ribbon in the sapphire is obvious, and the polycrystalline twin crystal is not developed. The outer edge of the large crystal can be seen as a growth line parallel to the hexagonal cylinder. Shandong sapphire is a high quality sapphire because of its internal defects.
