The "Lie Detector" for Gold Jewelry
1. Weigh Your Chain: Put your chain on a gram scale. Be precise (e.g., 42.5g).
2. Measure Width: Use a ruler or calipers to get the width in millimeters (mm).
3. Analyze: The meter will calculate the density. If it hits RED, your chain is likely hollow or semi-hollow.
Hollow chains are sold at "Solid" prices to trick beginners. They dent easily, cannot be repaired easily, and hold 60% less gold value.
