The authenticity of gold is not judged by the sound of landing, because the density of gold is higher than other metals, so its sound is usually dull and continuous. If gold falls to the ground and makes a crisp sound, it may be because it contains other metals or alloys, or it may be processed into a hollow or hollow shape.

Huicuilou is a well-known gold brand, and its jewelry and ornaments are usually made of real gold. If the gold purchased by Huiju Building has a steel seal, it is probably real gold. However, if the sound of falling on the ground is abnormal, it is recommended to send it to a professional jewelry appraisal institution for testing to ensure its authenticity.
