Lab-grown diamonds have increasingly gained popularity due to their ethical and environmental advantages over mined diamonds. With their growing presence in the market, it's natural to wonder whether these diamonds can pass a diamond tester, an instrument commonly used to verify the authenticity of diamonds. In this article, we'll explore the capabilities of diamond testers and their effectiveness in distinguishing lab-grown diamonds from natural ones.
Diamond testers operate by measuring the thermal or electrical conductivity of a gemstone. Since diamonds are exceptional conductors of heat and electricity, unique among other gemstones, these measurements often suffice for confirming a stone's identity. However, lab-grown diamonds possess the same chemical, physical, and optical properties as mined diamonds, making the differentiation between the two challenging by conventional testing methods alone.
Advanced testing techniques at gemological laboratories may be necessary to accurately identify lab-grown diamonds, especially when dealing with smaller gemstones of less than 0.10 ct. The use of specialized equipment and the expertise of qualified gemologists is crucial in determining whether a diamond is indeed grown in a lab or formed naturally in the earth's crust. In the following sections, we will delve deeper into various testing methods and their effectiveness in separating lab-grown diamonds from their natural counterparts.
Understanding Lab-Grown Diamonds
Lab-grown diamonds, also called lab-created or lab-made diamonds, are becoming a popular and sustainable alternative to natural diamonds. These diamonds are created using advanced technologies that replicate the conditions found in the Earth's mantle, giving them the same physical, chemical, and optical properties as natural diamonds.
There are two primary methods for producing lab-grown diamonds: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). HPHT recreates the natural process by exposing carbon to extreme heat and pressure, while CVD deposits carbon gas onto a substrate, allowing the diamond to grow layer by layer. Both methods result in high-quality diamonds suitable for jewelry and industrial use.
A common question is whether lab-grown diamonds can pass a diamond tester. These testers measure properties like thermal conductivity, which is higher in diamonds than in stones like cubic zirconia or moissanite. Since lab-grown diamonds have the same characteristics as natural diamonds, they do pass standard diamond tests.
However, specialized tools and tests can distinguish lab-grown diamonds from natural ones. These advanced tests examine growth patterns, inclusions, and trace elements. Additionally, many lab-grown diamonds come with laser inscriptions on their girdles, identifying them as lab-created, which helps prevent confusion.
In conclusion, lab-grown diamonds are nearly indistinguishable from natural diamonds in terms of appearance, durability, and properties. While they pass basic diamond testers, more advanced methods can differentiate them. As awareness of their benefits grows, lab-grown diamonds are becoming more accepted and favored by consumers.
The Science Behind Diamond Testing
Diamond testing is essential for determining a diamond’s authenticity. It typically involves assessing key properties like thermal and electrical conductivity to differentiate between natural diamonds, lab-grown diamonds, and simulants.
Thermal conductivity is the primary property measured, as diamonds have a unique ability to disperse heat more efficiently than most gemstones, such as cubic zirconia or moissanite. Diamond testers detect this heat transfer to confirm the stone’s authenticity.
Electrical conductivity is another factor tested. Natural diamonds usually have low electrical conductivity due to their pure crystal structure, but lab-grown diamonds created using the High Pressure High Temperature (HPHT) method may contain metallic impurities, which can increase conductivity. This can make it challenging to distinguish between lab-grown and natural diamonds using basic tests.
While superconductivity, a phenomenon where materials exhibit zero electrical resistance, isn’t directly involved in diamond testing, boron-doped diamonds can show superconductivity under specific conditions. However, this property has minimal impact on standard diamond testing.
To enhance accuracy, many diamond testers now use a multi-stage approach, combining thermal and electrical conductivity measurements with other testing methods. This comprehensive approach ensures more precise identification of natural versus lab-grown diamonds.
In conclusion, diamond testing is a detailed process that relies on advanced techniques to accurately distinguish between diamond types. Multi-stage tests improve accuracy, ensuring that lab-grown and natural diamonds are properly identified.

Natural and lab-grown diamonds share many similarities but exhibit key differences in physical and optical characteristics. Both types score 10 on the Mohs hardness scale and have nearly identical densities, making them indistinguishable in these aspects. However, lab-grown diamonds often display more uniform, intense colors due to controlled manufacturing, while natural diamonds offer a wider color range. Lab-grown diamonds also tend to have fewer inclusions, whereas natural diamonds may feature unique internal characteristics.
The diamond's girdle can provide clues: lab-grown diamonds typically have a polished or faceted girdle, while natural diamonds often have an unpolished one, though this distinction is not always reliable. Optical properties also differ, as natural diamonds may exhibit double refraction, while lab-grown diamonds might not.
To distinguish between the two, advanced tools like spectroscopy and diamond testers measuring thermal conductivity are necessary.
Simulants and Counterparts
Diamond simulants, like cubic zirconia, moissanite, white sapphire, white topaz, and glass, imitate diamonds but have different chemical and physical properties. These materials are popular in jewelry due to their affordability and availability compared to natural diamonds.
Among simulants, cubic zirconia and moissanite are the most common. Cubic zirconia, a synthetic gemstone, resembles diamonds but is softer and less durable. Moissanite, a naturally occurring crystal, is lab-grown, offering brilliance and hardness similar to diamonds, making it a popular alternative.
Other simulants include white sapphire, white topaz, and glass. White sapphire, a natural gemstone, sparkles similarly to diamonds but is less durable. White topaz, softer than diamonds, is prone to scratching. Glass, although inexpensive and widely available, lacks both the durability and brilliance of diamonds.
Lab-grown diamonds, unlike simulants, share the same chemical and physical properties as natural diamonds. They are created through advanced methods, offering an environmentally friendly and ethical alternative. Lab-grown diamonds, when tested, are usually indistinguishable from natural diamonds, unlike simulants.
Diamond testers measure the thermal or electrical conductivity of gemstones to determine if they are genuine diamonds. Lab-grown diamonds pass these tests, but most simulants do not, allowing testers to differentiate between them.
In conclusion, while diamond simulants resemble real diamonds, their differing properties set them apart. Lab-grown diamonds, however, pass diamond testers just like natural diamonds, while simulants are recognized as non-diamond materials.
Role of Diamond Testers
Diamond testers are vital tools in the gem industry, helping to determine a diamond's authenticity by measuring thermal and electrical conductivity. Thermal conductivity refers to how quickly a material absorbs and dissipates heat. Diamond testers evaluate this by measuring the speed at which heat transfers from the tester’s tip to the stone. Natural diamonds exhibit high thermal conductivity, but lab-grown diamonds can sometimes show similar values, making it difficult to rely solely on this test.
Electrical conductivity testing adds another layer of analysis by measuring the flow of electrical currents through a diamond. While diamonds generally have low electrical conductivity, some lab-grown diamonds, especially those created using the High-Pressure High-Temperature (HPHT) method, can exhibit higher conductivity, providing an important clue to their origin.
However, diamond testers are not always foolproof. False negatives can occur, especially with lab-grown diamonds that mimic the thermal and electrical properties of natural diamonds. In some cases, are lab grown diamonds real diamonds are optically identical to natural ones, making them difficult to differentiate through visual inspection alone.
In conclusion, use diamond testers to evaluate a diamond's thermal and electrical properties alongside optical inspection and advanced laboratory analysis to determine its true origin.
Technological Processes in Diamond Creation

These carbon atoms then deposit onto a substrate, forming layers that eventually grow into a diamond. The CVD method enables the production of high-quality diamonds with precise control over their properties, such as size, clarity, and color.
- High Pressure High Temperature (HPHT), on the other hand, replicates the natural conditions deep within the Earth's mantle, where diamonds typically form. During HPHT, a carbon source is place within a press that exerts immense pressure and heat. The carbon atoms are force together under these extreme conditions, creating a diamond structure. HPHT produces diamonds with remarkable traits, similar to those found in nature.
Both CVD and HPHT diamonds can be subject to various post-growth treatments to enhance their appearance and properties. Some diamonds might undergo irradiation to modify their color or high temperature treatments to increase their clarity.
When it comes to detecting lab-grown diamonds, standard diamond testers may not always provide conclusive results. Most diamond testers measure thermal or electrical conductivity, but advanced methods like spectroscopy can distinguish lab-grown from natural diamonds.
In conclusion, the technological processes of CVD and HPHT have enabled the creation of high-quality lab-grown diamonds that have similar properties to natural diamonds. While standard diamond testers might not distinguish them from natural diamonds, more advanced detection techniques can uncover the differences between the two.
