Matters needing attention in buying jewelry

Weigh. If the object is gold, it feels heavy, which is what people call "gold falling into the hand", and vice versa.

Look at the color. Pure gold will shine brilliantly in strong light, which other metals, including copper, do not have.

Listen to the rhyme. Gold jewelry was thrown on the ground with a plop sound. The falsetto is sharp and bright, jumping higher than gold.

Fold hard and soft. Gold has the characteristics of good ductility and low hardness. Pure gold is very soft to fold, and copper bars are very laborious to fold.

Use acid. Gold is insoluble in acid, but it will react with acid solution because it is mixed with other active metals such as copper.
