Color can distinguish the authenticity of Nanhong by color. Natural South Red has bright colors and obvious stripes. If you look closely, you can see a lot of densely arranged little red dot, while the fakes are brightly colored and unnatural.
Glossy natural Nanhong has a high gloss, giving people a feeling of crystal clear and bright, and it is highly reflective and feels good in the hand, while fake Nanhong has a rough texture and a dull surface luster.
There are more or less waterlines on the naturally formed Nanhong bracelet, which is easier to see under the illumination of light, and the trend is irregular, while the fake Nanhong has no texture, and even if it does, it is evenly distributed.
