Precious material analysis using vibration signature comparison

A precious material analyzer for determining one or more characteristics of an unidentified precious material comprising:

• a vibration injector that causes the unidentified precious material to vibrate with a vibration signature that is dependent on the one or more characteristics of the unidentified precious material;
• a vibration detector that detects and extracts the vibration signature from the vibration of the unidentified precious material caused by the vibration injector;
• and
• a vibration signature comparator that:
• compares the detected vibration signature of the unidentified precious material with vibration signatures of multiple identified precious materials having one or more identified characteristics;
• and
• flags one or more of the identified precious materials that have vibration signatures that match the vibration signature of the unidentified precious material,
• wherein the unidentified precious material includes at least one selected from the group consisting of gemstones, gold, silver, platinum, rhodium, iridium, and palladium, and
• wherein the vibration injector causes the unidentified precious material to vibrate simultaneously at multiple different frequencies;
• the vibration detector detects the vibration signature of the unidentified precious material at each of the multiple different frequencies;
• and
• the vibration signature comparator:
• compares the detected vibration signature of the unidentified precious material at each of the multiple different frequencies with vibration signatures of the multiple identified precious materials at each of the multiple different frequencies;
• and
• flags at least one of the one or more of the identified precious materials that have vibration signatures at the multiple different frequencies that match the vibration signature of the unidentified precious material at the multiple different frequencies.
