Quality｜Ruby｜<<Unheated>> Natural rubies produced in the north of Hanoi, Vietnam. Without any processing, the unique crystal texture of rubies is clearly visible, and no matter the type or strength of the light source, you can see a few flames of light flickering in the gemstone (see the video below), which is the most important and unique feature of rubies. In recent years, various evidences show that the global production of rubies has approached 0, and it is a gemstone that is on the verge of extinction. In the past, Myanmar, a well-known production area, almost no rubies can be dug. Now, the rubies circulating in the market are all produced in Mozambique, Africa. In addition, although there are also rubies in other places such as Thailand, Vietnam, etc., they are all sporadic production at this stage. It is said that emeralds have many inclusions, but in fact, there is another gemstone in the world whose clarity can compete with emeralds, that is ruby. Clarity will widely affect the color of gemstones. Most rubies are flat and dull if they are not treated. Even after treatment, they still look like a piece of dark red plastic without any transparency, just like a ruby that has been in a grandmother's drawer for 40 years. This is what most natural rubies look like. In contrast, the color of this ruby seems to be full of vitality, full of chromium, and bright and sparkling! Ruby is a red gem-grade corundum with a Mohs hardness of 9. It is the hardest natural substance on earth besides diamond. It has been called the king of gemstones since ancient times. The Bible describes ruby as representing the wisdom of the universe and has the supreme status among all gem minerals. Clarity | I-1: This grade of gemstone means that there are many inclusions in it and they are visible to the naked eye. This grade of clarity is enough to affect the beauty of the gemstone, but it is not completely applicable to emeralds and rubies. Because these two gemstones are extremely rare, if you want a flawless grade, you may have to wait for a long time. The waiting time can be calculated every ten years. Quantity | 0.45 carats.
