How to identify raw diamonds?

Have you ever examined a diamond under a loupe or microscope and noticed its round edges with tiny indented triangles? Cubic diamonds, on the other hand, will feature parallelograms or rotated squares. A genuinely raw diamond should appear to have an even coat of vaseline applied. Diamonds are highly prized gemstones for their beauty, strength, and rarity. Cut diamonds typically feature sharp edges. As a result, diamonds are among the most valuable and sought-after gems today. Diamonds come in many different shapes, sizes, and colors. Still, the most valuable and highly prized stones are those that are both rare and of exceptional quality. One way to identify such diamonds is by looking for raw uncut diamonds, which may be cheaper than cut and polished stones but still possess great worth. Here are some tips on recognizing raw diamonds.

1. Understand Diamond Properties

Before you can identify raw diamonds, it is essential to understand their fundamental properties. Diamonds are carbon crystals known for their hardness; this makes them highly resistant to scratching or wear. Furthermore, diamonds boast a high refractive index, making them excellent at bending and reflecting light, giving off their characteristic sparkle and brilliance. Lastly, diamonds may be valued based on clarity – the degree to which they are free of inclusions or blemishes.

2. Look for Rough, Uncut Stones

One of the simplest ways to identify a raw diamond is by inspecting for uncut stones. Raw diamonds typically reside in kimberlite pipes – long vertical columns of rock formed deep within Earth’s mantle that contain millions of years of crystallized diamonds created through intense pressure and heat over millions of years and brought to the surface through volcanic activity. Uncut diamonds may have dull exteriors but also possess that characteristic glassy or greasy sheen typical of diamonds.

3. Check the weight

Diamonds are renowned for their density or relative heaviness compared to their size. One way to identify a raw diamond is by weighing it and comparing it with similar-sized stones; typically, larger diamonds weigh more than smaller gems of similar shape and size.

4. Use a diamond tester

Another way to identify raw diamonds is with an electrical conductivity tester. Diamonds are excellent conductors of heat and electricity, while other stones, such as cubic zirconia or moissanite, cannot. Therefore, a diamond tester will produce a positive reading for diamonds but won’t detect other types of gemstones.

Diamond testers are instruments that use electrical conductivity to determine whether a gemstone is a genuine diamond or not. This process works by testing the gemstone’s capacity for heat conduction.

When a diamond tester is placed on a diamond, it sends an electrical charge through the gemstone. Diamonds are excellent conductors of heat, meaning they will transfer this charge quickly to give a high reading on the tester. Other gemstones, however, could be more efficient at conducting heat and thus won’t register as quickly on the instrument. This results in lower readings from other gems.

Diamond testers come in two varieties: thermal and electrical conductivity testers.

Thermal conductivity testers measure how well a material conducts heat. They do this by heating the tip of the tester and placing it on a diamond, where its cooling rate will determine whether or not the gemstone is indeed a diamond.

Electrical conductivity testers utilize a small electric current to determine whether a gemstone is a diamond. These tests measure how resistant each gemstone is to electricity flowing through them; diamonds have high electrical conductivity, meaning they allow electricity to pass through them quickly, while other gemstones have lower conductivities.

It’s essential to note that while diamond testers can accurately identify diamonds, they cannot determine their quality or value. To assess a diamond’s worth, it should be examined by an experienced gemologist.

5. Look for Specific Shapes

Diamonds come in various shapes and sizes, but some are more commonly associated with raw, uncut diamonds. These include octahedral, dodecahedral, and cubic shapes – the former looking like two pyramids joined at their bases while dodecahedral boasts 12 sides and an oval form; cubics, as the name implies, take the form of cubes.

6. Consider the source

It is essential to consider the source when identifying a raw diamond. Diamonds mined from specific regions, or mines may possess unique characteristics which make them easier to recognize. Furthermore, diamonds sold with certification from trusted organizations like the Gemological Institute of America (GIA) are genuine and of superior quality.

7. Use a microscope or 10x loupe to examine the stone closer

When trying to identify raw diamonds, using a microscope or 10x loupe can be invaluable. These instruments allow for a closer examination of their characteristics and may provide insight into their origin and potential value.

Before inspecting a diamond under a microscope or loupe, it is essential to clean it thoroughly. That can be accomplished using mild detergent and warm water, followed by an occasional wipe with a soft cloth or tissue. Any dirt or debris on the surface of the diamond will make it difficult to analyze its characteristics accurately.

Once the diamond has been cleaned, closely examine its features using a microscope or loupe. Search for any inclusions or imperfections which can help identify its origin and provide insight into its value. Inclusions are minute cracks or fissures within the stone caused by pressure, heat exposure, or minerals present during formation.

Under a microscope or loupe, carefully examine the diamond’s color. Look for any variations in hue or saturation which could indicate its origin and potential worth. Completely colorless diamonds are considered the most valuable; those with yellowish or brownish tints may be less valuable.

Another key characteristic to assess when buying a diamond is its shape and cut. Be looking for any irregularities or asymmetry in its shape, which could indicate the lower quality or possibly man-made material. To enhance its brilliance and value, a properly cut diamond should have perfectly symmetrical and proportionate facets.

How do you know whether the diamond was discovered near kimberlite pipes?

One way to determine whether a diamond was discovered near kimberlite pipes is by inspecting its characteristics. Kimberlite pipes are long, narrow columns of rock formed deep within the Earth’s mantle that contain diamonds. When these minerals are brought up by volcanic activity, they often end up near nearby kimberlite pipes.

One way to identify a diamond found near a kimberlite pipe is its shape. Diamonds near these pipes typically have an oval shape with a flat or rounded bottom and pointed top, known as an octahedron. This formation occurs when a smaller diamond crystal breaks off from another giant crystal within the kimberlite pipe.

Another characteristic that can identify a diamond found near a kimberlite pipe is its color. Diamonds found near these rocks tend to be less saturated in hue and may exhibit a slight grayish or brown tint due to other minerals present.

Finally, when determining whether a diamond was found near a kimberlite pipe, it’s essential to consider its source. Diamonds certified by an authoritative organization such as the Gemological Institute of America (GIA) may include information regarding the location and conditions in which it was discovered, which can help pinpoint whether it was indeed near one.

Though it can be difficult to confirm whether a diamond was discovered near a kimberlite pipe, several characteristics and factors can help make an educated guess. For example, examining a diamond’s shape, color, and source all provide clues as to its possible connection; this helps diamond experts and collectors better comprehend its history and value.

How to tell the difference between a real diamond and a fake one?

Spotting the difference between an authentic diamond and a fake can be tricky, but there are some telltale signs. Here are some tips on recognizing a genuine gemstone:

1. Check for reflection: A real diamond will reflect light and sparkle, while a fake may not have the same level of brilliance. Hold the stone to a light source and observe how it reflects it.

2. Look for inclusions: Real diamonds typically have minor inclusions or imperfections within their stone, while fakes may appear too flawless. Utilizing a microscope or 10x loupe, scrutinize the stone for any cracks or spots which could indicate that it is indeed a genuine diamond.

3. Check the weight: Real diamonds are dense and heavy so a real stone will feel heavier than a fake of similar size. That can be tested by weighing the stone against an established weight for that size stone.

4. Use a Diamond Tester: Silver testers are sophisticated devices that determine whether a stone is real or fake. They work by measuring the thermal conductivity of the stone, which is unique to diamonds.

5. Look for a hallmark: Some diamonds have certification from trusted organizations, such as the Gemological Institute of America (GIA). This can give you peace of mind that the stone is real and provide helpful information about its characteristics and value.

6. Check the price: If a diamond appears too good to be true in terms of its price, it could be an imitation. On the other hand, real diamonds are valuable and usually quite costly, so any significantly reduced value could indicate that you’ve found something fraudulent.

How to identify raw diamonds in rocks?

Finding raw diamonds in rocks can be difficult, but there are some methods you can use to increase your chances of finding them. Here are some steps you should take:

Look for diamond-bearing rock formations: Diamonds are often found in kimberlite pipes, which bring diamonds from deep within the Earth’s mantle to the surface. Look out for exposed rock formations that contain diamonds, such as those in Australia’s Northern Territory, Canada’s Shield, and Africa.

Know What to Look For: Raw diamonds are octahedral in shape with a distinctive metallic luster. They may appear greasy or waxy and have an even surface with few small pits or flat faces.

Use a black light: Diamonds fluoresce under ultraviolet (UV) light, so using a black light to spot them can be helpful. Shine the light on the rocks you are inspecting and look for any bright, glowing areas which could indicate diamonds present.

Conduct a Hardness Test: Diamonds are the hardest mineral on the Mohs scale, with an intensity rating of 10. It means they can scratch any mineral. To test for hardness, scratch the rock with either a glass or metal file; if it scratches neither, it is not likely to be diamonds but another hard mineral.

Conduct a Density Test: Diamonds have an exceptionally high density compared to most other minerals. To test for diamonds, fill a container with water and measure its volume. Then, weigh the rock you inspect before submerging it in the liquid; measure how much water it displaces by dividing its weight by the volume displaced. If the density comes close to 3.52 g/cm3, chances are good that you have found yourself a diamond!
