Product｜Aquamarine・Sea Sapphire Quality｜Pure, transparent, cool sea sapphire from Malawi, Africa. Compared to normal sea sapphire, its blue is thicker. Of course, in the category of treasure gems, there is no gem that has been processed, without exception. Because the main ways to change the color of sea sapphire are heating and radiation (this is the way many gems are optimized), and heating to deepen the color of sea sapphire is a common method used by many merchants; and the current inspection technology cannot measure whether the blue color of sea sapphire is achieved through heating and radiation. As for whether consumers buy it, it is actually a matter of opinion, but it is more reasonable for the store to proactively inform. Sea sapphire belongs to the beryl category, with a Mohs hardness of 8, which is a gem that is quite suitable for wearing. Clean｜FL [Flawless means flawless.
