Ruby identification

Natural gemstones, "Red, Yellow, and Cracked", are very rare and naturally ruby ​​without any flaws or cracks. The artificial ruby ​​has the same color, with fewer internal defects or crystal inclusions, clean, and large blocks. As a precious gemstone, natural rubies exceeding 3 carats in the market are rare. If rubies are encountered in larger blocks, we must pay attention because natural rubies are thousands of times more valuable than man-made rubies. "Take medicine."

Natural rubies have a strong "dichroism", the so-called dichroism, that is, from the different directions, there are two colors of red and orange-red, if there is only one color, it may be red spinel, garnet or red glass. Wait.

The red spinel is very similar to the natural ruby, and the two are the most confusing, so we must be very careful.
