Step-by-Step Guide: How to Identify a Raw Diamond

Step 1: Look for Unique Characteristics

Raw diamonds have unique characteristics that distinguish them from other minerals. They are typically transparent or translucent and have a crystal-like shape. However, they can also be opaque or appear as rough and irregular shapes.

Step 2: Test for Hardness

One of the key characteristics of a raw diamond is its hardness. Diamonds are the hardest mineral on Earth, with a rating of 10 on the Mohs hardness scale. You can test for hardness by scratching the suspected diamond against a piece of glass. If it leaves a scratch, it is likely a diamond.

Step 3: Check for Refractivity

Diamonds also have high refractive indexes, which means they bend light in a unique way. To check for refractivity, place the suspected diamond over a piece of text or a dot on a white paper. If you see a doubled reflection, it is likely a diamond.

Step 4: Use Specialized Equipment

For a more accurate identification, you may need specialized equipment such as a diamond tester or a loupe. These tools can help you determine the properties of the diamond, such as its thermal conductivity or fluorescence.

Conclusion

Identifying a raw diamond can be a difficult task, but with the right tools and knowledge, you can increase your chances of success. Remember to look for unique characteristics, test for hardness, check for refractivity, and use specialized equipment if necessary. If you are unsure about the identification, it’s always best to consult with a professional gemologist.
