Lab-grown diamonds are often referred to as man-made or synthetic diamonds. Rather than forming on Earth through geological processes, these diamonds are produced in laboratories using techniques such as high temperature and pressure or chemical vapor deposition.
Here are some ways to identify lab-grown diamonds:
- Preço: Lab-grown diamonds are usually much less expensive than natural diamonds. If you find an inexpensive diamond that is similar in size and color to a natural diamond of the same grade, it is likely lab-grown.
- Cor: Lab-grown diamonds tend to have different colors, such as light yellow or light brown, while natural diamonds are often colorless or have a faint hue. If you see a diamond that is very dark or light in color and it is inexpensive, it is probably lab-grown.
- Internal Features: Lab-grown diamonds often have distinct internal features such as spots, lines, or air bubbles. These characteristics are rarely found in natural diamonds. If you see these features inside the diamond, the diamond is probably lab-grown.
- Certificado: If you’re buying a diamond, make sure it comes with a reputable report, such as one from the Gemological Institute of America (GIA). These reports detail the diamond’s quality, weight, size, and color, among other characteristics, and indicate whether it is natural or lab-grown.
In conclusion, if you want to determine whether a diamond is natural or lab-grown, it is best to find a professionally trained jewelry appraiser to do it. They can use a variety of instruments and techniques to identify a diamond’s origin.
