This kind of bracelet can be identified by color and light transmittance.

1, color: dragon blood string is as red as blood. This kind of red is very bright and even, without any impurities. The fake dragon blood string is light or dark, even mottled. The red color of the dragon blood string comes from the rich red pigment and resin, which is formed by long-term natural growth.

2, light transmittance: the real dragon blood string has a certain light transmittance. When illuminated by strong light, the bracelet will show obvious red light transmission, because its internal resin and delicate texture can refract and reflect light. The fake dragon blood release string does not have this transparency, or the light transmission color is obviously different from the real dragon blood release string.
