1. Particle size: The larger the ruby ​​particle size, the higher the price.
2. Color: There are many colors of ruby, the best is darker red, followed by reddish purple, followed by darker pink, purple, slightly brownish red, others like brownish red. Blackish red, very light pink is a poor ruby. In addition, when observing the ruby ​​from the table top, it is best to see only one color when rotating. If other colors are visible, the orientation of the ruby ​​is not correct.
3. Fire color: It is the color of the ruby ​​front under the illumination of the light source. It is essentially a reflection of the transparency, cut and color of the ruby. A good ruby ​​is gently turned (the table is facing Own), it can be seen that there are many small red "fires" in the interior, and for high-quality rubies, the fire color should account for more than 55% of the entire crown.
4. Cracks: Since the cracks of rubies are more common, you should try to pick rubies with less cracks and fineness when selecting them, especially not to pick the ruby ​​rings that pass through the center of the gemstone.
