This statement is not accurate. A thousand pieces of cigarette paper can't make a gold bracelet, let alone burn it to verify its authenticity.
First of all, a gold bracelet is a valuable metal ornament, usually made of gold. Gold is a precious metal with high value, which is usually used to make jewelry, investment products and so on.
Secondly, cigarette paper is a kind of paper used to pack cigarettes, usually made of fiber and glue. Its texture is thin and easy to break, and it can't bear heavy weight or pressure.
Therefore, a thousand pieces of cigarette paper can't make a gold bracelet. This statement is incorrect and should not be believed. If you want to identify the authenticity of the gold bracelet, you'd better send it to a professional jewelry testing institution for testing.
