Image Description: A skilled jeweler carefully operates an advanced electronic gold tester, expertly analyzing the purity of a shimmering gold ring. The device emits a soft hum as it calibrates, the jeweler's focused eyes watch the digital screen closely. As the probe makes contact with the polished surface of the ring, subtle beeping signals the machine’s readings. The jeweler meticulously records the results, ensuring the ring's quality and authenticity are verified before presenting it to a discerning customer.

Traditional Tools for Testing Gold
