How to Identify a Raw Diamond

Diamonds are a valuable and sought-after gemstone that have been treasured for centuries. However, not all diamonds are created equal and it's essential to know how to identify raw diamonds to make an informed decision when buying one. In this guide, we will take a closer look at the characteristics of raw diamonds and how to identify them.

Characteristics of Raw Diamonds

Raw diamonds, also known as rough diamonds, are diamonds that have not been cut or polished. They are typically found in the form of a rough stone that has a natural crystal shape. Raw diamonds can be any color, but the most common color is yellow or brown.

These diamonds can also have inclusions, which are natural imperfections found inside the diamond. Inclusions can be anything from other minerals or crystals to fractures or bubbles. The presence of inclusions does not necessarily mean that the diamond is of lower quality, but it can affect the value of the stone.

Identifying Raw Diamonds

There are a few key things to look for when identifying raw diamonds:

1. Hardness: 

Diamonds are the hardest known mineral and they should be able to scratch any other mineral. If a stone can be scratched with another mineral, it is likely not a diamond.

2. Sparkle: 

Raw diamonds have a natural sparkle, but it will be less intense than a cut and polished stone. Hold the diamond in the light and observe the sparkle. If the gemstone reflects light in all the colors of the rainbow, it’s a good indication that it might be a diamond.

3. Transparency: 

Rough diamonds are partially transparent, so if you hold the stone to the light you should be able to see through it.

4. Luster: 

With a unique luster, a raw diamond stands out. The stone should have a smooth surface that looks like it could be oily.

5. Carat weight: 

Diamonds are measured in carats. A higher carat weight means a bigger diamond. Keep in mind that bigger isn't always better when it comes to diamonds, as the value of a diamond is also determined by its overall quality.

6. Certification: 

If you're unsure whether a diamond is real or not, you can have it certified by a professional. A diamond certification is an independent evaluation that confirms the stone’s characteristics and quality.

Identifying raw diamonds can be a tricky task. Still, by looking at its characteristics, such as hardness, sparkle, transparency, luster, carat weight and certification, you can make a more informed decision when buying one.
