How to tell if diamonds are real?

Aug 25, 2024

Diamonds have long been associated with luxury and timeless beauty, so knowing how to authenticate diamonds when purchasing wedding ring sets or an impressive gold engagement ring set is essential when shopping. Given all the counterfeit stones on the market today, knowing the differences between authentic and fake diamonds can help identify real ones quickly and accurately. But, How to tell if diamonds are real?

1. The Water Test

One of the easiest and fastest methods of verifying diamond authenticity is with the water test; all it requires is some clean drinking water and the item being tested - including, of course, your diamond!

How to Conduct the Water Test:

  • Fill a glass with water. Carefully drop the diamond into it.

Results:

  • A diamond that sinks to the bottom may well be real.
  • If something floats just beneath the surface, it could be fake.

Diamonds are denser than most imitation stones and will therefore sink when submerged in water; however, this test alone cannot provide accurate results; therefore it's recommended to use it alongside additional methods of verification.

2. Fog Test

A quick and straightforward method for verifying whether a diamond is real is to conduct the "Fog Test", taking advantage of their high conductivity of heat to gauge authenticity. This test relies on their natural ability to transmit heat inefficiently such that any fog from heating a surface won't affect it as quickly.

How to Do the Fog Test:

  • Hold the diamond between two fingers.
  • Breathe into a stone to produce a light fog.

Results:

  • If the fog dissipates quickly, then your diamond is real.
  • If the fog hangs around for more than several seconds, it might be faked.

Diamonds radiate heat rapidly, which allows any moisture present to evaporate quickly - this provides an effective method of differentiating between an authentic and an imitation diamond.

3. Assessing the Environment and Mount

As part of a diamond's examination process, it's also vitally important to take note of its setting and mount. Real diamonds usually feature high-grade metal settings like gold or platinum to complete their beauty and value.

What to Look For:

  • Stamp Markings: Real diamonds often feature hallmarks such as 10K, 14K, or 18K for gold settings or "PT" (for platinum). If a stone bears "C.Z" markings it could indicate its status as cubic zirconia instead.
  • Prongs: Prongs or bezel settings often secure diamonds to their settings; if these appear cheap or poorly made, there could be reason to suspect the diamond may not be real.

At Pompeii3, our selection of gold engagement rings and wedding ring sets feature only premium-grade diamonds set into premium materials to guarantee authenticity and long-term performance.

4. The Newspaper Test

This test relies on the diamond's ability to disperse light, making it hard for us to see through.

How to Conduct the Newspaper Test:

  • Flip your diamond upside-down on a piece of newspaper for easy display.
  • Use the diamond as a guide to read your print out loud.

Results:

  • When letters can't be seen, then it means the diamond is real.
  • If the letters on a diamond can easily be seen, this indicates its falsity.

Real diamonds boast a high refractive index that bends light so strongly, that its path cannot be seen through. This makes real diamonds so brilliantly reflective in light.

5. Professional Appraisal

Although at-home tests may provide some indication, the only reliable way to verify whether a diamond is real is through having it professionally appraised by certified gemologists using advanced equipment to analyze the authenticity and provide you with a detailed report.
