Basic Introduction of Changle Sapphire

The mineral name of sapphire is corundum, which belongs to the corundum group of minerals. Sapphire, with its crystal clear and beautiful color, was shrouded in mysterious and supernatural hues by ancient people and regarded as an auspicious object. Sapphire can be divided into blue sapphire and bright (non blue) sapphire. In the 1980s, many sapphire deposits were discovered in the basalt along the eastern coast of China, among which Shandong (Changle) sapphire had the best quality. What are the product features of Changle Sapphire? Changle Sapphire was formed by a volcanic eruption 18 million years ago. The primary ore body is mainly alkaline olivine basalt. The gemstones produced by Changle have the characteristics of large crystal particles, complete crystals, pure color, strong bichromaticity, high purity, few cracks, many unique gemstones, and high yield. The crystals are mostly hexagonal double cones and plate shaped aggregates, forming waist drum and plate shapes, with particle sizes ranging from 3-20 millimeters. The largest discovered crystal diameter is 80 millimeters and weighs over 700 carats. How did the history of Changle Sapphire come about? In the world of gemstone culture, sapphire is endowed with wisdom and auspiciousness due to its mysterious and dreamlike color, while also symbolizing romantic love. In fact, as early as the Zhou Dynasty 3000 years ago, this place was once glorious. Today, Yingqiu Village in Changle County was the earliest capital of Qi State at that time. The first ruler of Qi State was the famous ancient Chinese scholar Jiang Ziya - Jiang Taigong, who ruled the country for 50 years. It can be said that this is the pioneering place of Qilu culture. In the folk of Changle, there are countless stories about the ingenious schemes of Jiang Taigong, but it is amusing to say that he predicted the existence of sapphires in this area 3000 years ago... There are two types of sapphire deposits. One is primary ore, and the other is sapphire sand ore. The coexistence of primary and sand minerals in Changle sapphire is also unique in the world. Sapphire primary ore is formed by the crystallization of molten magma under high temperature conditions in the deep surface during volcanic eruptions. These crystals are enveloped by cooled lava, thus forming sapphire primary ore. Sapphire sand mines are exposed primary minerals that have been eroded by nature over time, gradually weathered and stripped away. Basalt formed from magma is weathered into gravel, and sapphire crystals wrapped in it are stripped off and mixed with basalt gravel. They are washed down from high to low by water flow, and then washed and transported by floods, forming vast sand mines.
