How the Daimond teater works:

Diamond testers work by measuring the thermal conductivity of a material to determine whether it is a genuine diamond. Diamonds have a unique ability to conduct heat efficiently, more so than most other gemstones. This characteristic is due to the strong covalent bonding between carbon atoms in a diamond’s crystal lattice, which allows heat to dissipate quickly through the structure.

A diamond tester features a small, probe-like tip that is applied to the gemstone. When the tip touches the stone, the device sends a small amount of heat into the stone and then measures the rate at which the heat moves away from the probe. If the heat disperses quickly, indicative of high thermal conductivity, the device signals that the stone is likely a diamond. If the heat disperses slowly, it indicates lower thermal conductivity, suggesting that the stone is not a diamond but perhaps a different gemstone or a synthetic substitute with similar appearance but different physical properties.
