Can a Jeweler Tell if a Diamond Has Been Enhanced? 5 Key Methods Explained

A jeweler can indeed tell if a diamond has been enhanced or is synthetic through various methods and tools.

5 Key Methods Explained

Can a Jeweler Tell if a Diamond Has Been Enhanced? 5 Key Methods Explained

1. Diamond Testers

Specialized diamond testers can distinguish between natural and synthetic diamonds, as well as detect if a diamond has been treated.

These testers use different technologies such as ultraviolet short waves, which differ from traditional heat and electrical conductivity methods.

They can identify various characteristics like color range (D to J), and can test both mounted and loose diamonds.

2. Magnification

Examining the diamond under magnification can reveal differences between lab-grown and natural diamonds.

Lab-grown diamonds typically have fewer surface imperfections due to their controlled growth environment.

This method helps in identifying the presence of inclusions or surface scratches that are common in natural diamonds but less frequent in synthetic ones.

3. Spectroscopy and Luminescence

Laboratories employ advanced techniques like spectroscopy, microscopy, and luminescence under shortwave ultraviolet light to determine a diamond's origin.

Tools such as the DiamondSure and DiamondView, developed by De Beers and marketed by the GIA, are used for this purpose.

These tools can detect specific characteristics like orange fluorescence in CVD diamonds or minor imperfections in natural diamonds that are not present in synthetic ones.

4. Chemical and Physical Properties

While lab-grown diamonds closely match the chemical and physical properties of natural diamonds, they can still be differentiated by their slight variations in radioisotope emissions, which are often carbon-11 enriched.

This requires specialized knowledge and equipment but provides a reliable method for distinguishing between the two.

5. Electrical Conductivity

Some diamond testers measure electrical conductivity, which is particularly useful in differentiating diamonds from simulants like moissanite, which can be challenging to distinguish using traditional heat-based testers.
