Product｜Blue-purple bicolor sapphire・Quality｜<<Unheated>> Colored sapphires mined from Luc Yen, VietNam, North Vietnam. The sapphires in North Vietnam are hidden in the mountains. The terrain is an extension of the limestone karst terrain of Guilin, Guangxi, China. Mining is extremely difficult, and the external transportation is extremely unchanged. Therefore, Vietnamese red and blue sapphires have always been rare in the international market. However, most of the sapphires produced are small in size and have a certain degree of silk inclusions, which makes the sapphires of various colors look very dreamy and lovely, which is very pleasing. Although most of them are not so-called top-level sapphires, from the perspective of individualism, gems should be selected according to personal aesthetic preferences, rather than purchased according to market prices or scoring standards. Vietnamese sapphires have very charming colors, and because heating will change the color, Vietnamese sapphires are almost not heated or processed. Sapphire is the most profound and complex top field in the industry. Vietnamese small sapphires are nothing more than a simple existence and a favorite of the niche market!
