Chinese Sapphires Gemstone

As with most gemstones that originate from China, the amount of data and information we are aware of is very limited. What we do know is that most of the gem quality Sapphires mined in the country come from the Shandong Province, which is situated on the East coast of the country. As the gem is mined in basaltic or magmatic deposits, they tend to have a tone that is very dark, often in excess of 95%. Under a microscope if you ever find small dark orange inclusions in your Sapphire, there is every chance that these are due to the presence of uranpyrochlore crystals which are often found in Sapphires from the Shandong Province.
