1. What Does A Raw Diamond Look Like In Nature?
Yes, raw diamonds look different from the polished gems you see in jewelry. Raw diamonds often appear as unassuming, uncut crystals with distinct features that set them apart from ordinary rocks. Understanding these characteristics is the first step in identifying a potential diamond in its natural form.
- Crystal Form: Raw diamonds often exhibit distinct crystalline structures. The most common forms include octahedral (eight-sided), dodecahedral (twelve-sided), and cubic. These shapes can be subtle but are key indicators.
- Color and Clarity: Unlike the clear and sparkling appearance of cut diamonds, raw diamonds can appear cloudy or opaque. The color varies from colorless to shades of yellow, brown, and even green. Inclusions, or internal imperfections, are also common.
- Surface Texture: The surface of a raw diamond is typically rough and lacks the smooth, polished facets of a finished gem. This texture reflects its natural state after being extracted from the earth.

2. How Can I Identify A Raw Diamond?
There are several methods to help you identify a raw diamond, but keep in mind that none are foolproof without professional verification. Here’s a breakdown of common techniques:
- Visual Inspection: Start by closely examining the stone. Look for the crystal forms mentioned above (octahedral, dodecahedral, cubic). Note the surface texture and color. Does it have a greasy or adamantine (diamond-like) luster?
- Scratch Test: Diamonds are incredibly hard, ranking 10 on the Mohs Hardness Scale. According to the Gemological Institute of America (GIA), only a diamond can scratch another diamond. Try to scratch a piece of corundum (like a sapphire or ruby) with the suspected diamond. If it scratches the corundum, that’s a very strong indication it could be a diamond.
- Water Test: Diamonds are exceptionally dense. Drop the stone into a glass of water. A real diamond will sink quickly. Less dense materials might float or sink slowly.
- Diamond Tester: Electronic diamond testers measure thermal conductivity. Diamonds disperse heat rapidly, unlike most other stones. These testers are relatively inexpensive and can provide a quick indication, though they aren’t always definitive.
- Mineral Testing Kit: A mineral testing kit includes tools and samples to test a stone’s hardness and other properties. Follow the kit’s instructions carefully.
- Professional Assessment: When in doubt, consult a certified gemologist. They have the expertise and equipment to accurately identify a raw diamond.
3. What Tools Do I Need To Identify A Raw Diamond?
Having the right tools can greatly assist in identifying raw diamonds, but it’s essential to understand that these tools are aids, not guarantees. Combining them with a keen eye and knowledge of diamond characteristics will increase your accuracy.
- Magnifying Glass or Loupe: A magnifying glass or jeweler’s loupe (10x magnification is standard) is crucial for examining the crystal structure, surface texture, and inclusions of a raw diamond. This allows you to spot subtle features that are not visible to the naked eye.
- Hardness Testing Kit (Mohs Scale): This kit includes a set of minerals with known hardness values, allowing you to perform scratch tests. A diamond should scratch all the minerals in the kit, confirming its superior hardness.
- Diamond Tester (Thermal Conductivity Meter): These handheld devices measure how quickly a stone conducts heat. Diamonds have high thermal conductivity, distinguishing them from many simulants. Be sure to calibrate the tester and follow the instructions carefully.
- Scale: A precise scale can help determine the density of the stone. Diamonds have a relatively high density, so comparing the weight to the volume can provide a clue.
- Ultraviolet (UV) Light: Some diamonds fluoresce under UV light. While not all diamonds fluoresce, observing the reaction can be another piece of the puzzle.
- Reference Materials: Keep a guidebook or chart of common minerals and their properties handy for comparison.
4. How Can I Tell A Raw Diamond From Quartz?
Distinguishing a raw diamond from quartz can be tricky for the untrained eye, as both can appear translucent and are found in similar environments. However, several key differences can help you tell them apart.
| Feature | Raw Diamond | Quartz |
|---|---|---|
| Hardness | 10 on the Mohs scale (extremely hard) | 7 on the Mohs scale (relatively hard but softer than diamond) |
| Crystal Structure | Typically octahedral, dodecahedral, or cubic | Hexagonal with pointed terminations |
| Luster | Adamantine (brilliant, diamond-like) or greasy | Vitreous (glassy) |
| Density | High (3.5 – 3.53 g/cm³) | Lower (2.65 g/cm³) |
| Inclusions | Often contains inclusions (small minerals or imperfections) | May contain inclusions, but they are typically different in appearance from those found in diamonds |
| Scratch Test | Will scratch corundum (ruby or sapphire) | Will not scratch corundum |

5. What Are Common Diamond Imitations?
Several materials are used to imitate diamonds, and it’s essential to be aware of them when trying to identify a raw diamond. Here are some of the most common diamond simulants:
- Cubic Zirconia (CZ): A synthetic material that closely resembles diamonds in appearance. CZ is much softer than diamond and lacks the same fire and brilliance.
- Moissanite: Another lab-created stone that is very convincing. Moissanite is harder than CZ but still not as hard as diamond. It also exhibits a different type of sparkle, often described as more “fiery” or rainbow-like.
- White Topaz: A natural gemstone that can look similar to diamond. White topaz is softer and lacks the brilliance of a diamond.
- Glass: Glass is sometimes used as a cheap diamond simulant. It is very soft and easily scratched.
- Synthetic Rutile: An older simulant that has a high refractive index and strong dispersion, giving it a lot of fire. However, it has a yellowish tint and is softer than diamond.
- Strontium Titanate: Also known as “Fabulite,” this simulant has a very high dispersion, giving it more fire than diamond. However, it is very soft and easily scratched.
6. How Does A Diamond Tester Work?
Diamond testers are handheld devices that help distinguish diamonds from simulants based on their thermal conductivity. The basic principle is that diamonds conduct heat much more efficiently than most other materials, including common diamond imitations.
Here’s how a typical diamond tester works:
- Preparation: The tester usually consists of a probe with a fine tip and a display screen. The device needs to be calibrated according to the ambient temperature.
- Testing: The probe is placed on the surface of the stone being tested. The tester sends a small electrical current through the probe.
- Measurement: The device measures how quickly the stone conducts heat away from the probe.
- Display: The results are displayed on the screen. A diamond will typically register with a high thermal conductivity reading, indicating that it is likely a diamond. Simulants will have lower readings.
It’s important to note that diamond testers are not foolproof:
- Moissanite: Some advanced testers can distinguish between diamond and moissanite, as moissanite also has relatively high thermal conductivity.
- Surface Coatings: Coatings on simulants can sometimes give false readings.
- Accuracy: Testers are best used as an initial screening tool, not as a definitive identification method.
7. What Should I Do If I Think I Found A Raw Diamond?
If you believe you’ve found a raw diamond, it’s essential to proceed with care and caution. Here’s a step-by-step guide:
- Handle with Care: Avoid excessive handling to prevent any potential damage to the stone.
- Document the Find: Note the location where you found the stone, as well as any other relevant details. This information can be helpful for future reference.
- Perform Initial Tests: Conduct the basic tests described earlier, such as visual inspection, scratch test, and water test.
- Seek Professional Verification: The most important step is to have the stone examined by a qualified gemologist or diamond expert. They have the knowledge and equipment to accurately identify the stone.
- Get an Appraisal: If the stone is confirmed to be a diamond, get it appraised to determine its value. The appraisal will consider factors such as size, color, clarity, and cut potential.
- Consider Your Options: Decide what you want to do with the diamond. You can keep it, sell it, or have it cut and polished into a finished gem.
- Legal Considerations: Be aware of any laws or regulations regarding the ownership and sale of diamonds in your area.
