Lab Grown Diamonds



Lab Grown Diamonds are chemically, physically, and optically identical to natural diamonds. Significantly less expensive and more sustainable.

  • Brilliance

    Lab Grown Diamonds are optically identical to Natural Diamonds. This means that Lab Diamonds are graded using the same 4C's as a mined Diamond and provide the same visual appearance full of brilliance and luster..

  • Sustainable

    Lab Grown Diamonds are real diamonds that are created in a laboratory setting using advanced technological processes making them a more sustainable option. When selecting a Lab Created Diamond you're keeping the earth in mind by not having to disrupt ecosystems with natural diamond mining.

  • Durability

    Lab Grown Diamonds are chemically and physically identical to natural diamonds. This means they have the same strength and durability that a naturally mined diamond has. Ranking 10 on the Mohs scale of hardness Lab Diamonds create superior center stones strong enough to withstand everyday wear.

  • Value

    Slate & Tell's Lab Grown Diamonds are an excellent value compared to Natural Diamonds of the same carat size and quality.



Discover the differences between Lab Diamonds & Natural Diamonds including durability, brilliance, and value.

Lab-grown diamonds have the same physical and chemical properties as natural diamonds, including hardness and durability. On the Mohs scale ofmineral hardness, lab diamonds are rated as a 10, the highest possible rating. This means that diamonds are extremely hard and are resistant to scratching and abrasions. However, lab-grown diamonds may not be as durable as natural diamonds because they may have a lower density, and may be more prone to chipping or breaking under certain conditions..
Natural diamonds are extremely hard and durable due to their unique crystal structure. On the Mohs scale of mineral hardness, diamonds are rated as a 10, the highest possible rating. This means that diamonds are resistant to scratching and abrasions from other minerals and materials. They are also very durable and can withstand high temperatures and pressures. They can only be scratched by another diamond.
Lab-grown diamonds have the same opticalvproperties as natural diamonds, which means they have the same level of brilliance. Brilliance refers to the amount of white light reflected by a diamond and is determined by the diamond's cut, shape, and faceting. Lab Diamonds often have a higher degree of symmetry and a more precise cut than many natural diamonds, which can result in a higher level of brilliance and contain fewer internal inclusions.
Natural diamonds are cut and polished in a way that maximizes their brilliance and sparkle. The unique properties of natural diamonds allow them to reflect light in a way that creates a bright , white sparkle. The way a natural diamond is cut can also affect its brilliance, a well-cut diamond will reflect more light and will have a higher brilliance than a poorly cut diamond. However, it is important to note that the internal characteristics of a natural diamond, such as inclusions or impurities, can affect the diamond's brilliance and overall appearance.
Lab-grown diamonds can come in a variety of colors, depending on the specific growth process used to create them. Our lab-grown diamonds are hand-selected with a Color of H-I and Clarity of SI1-SI2 and are cut with precision to display brilliance from all sides.
Colorless Natural Diamonds are the most common and highly valued, as they are considered the purest and rare. These diamonds are graded on a D-to-Z scale by the Gemological Institute of America (GIA), with D being the highest grade, indicating a completely colorless diamond.
Lab Grown Diamonds are generally less expensive than natural diamonds, due to the lower cost of producing them. Lab Diamonds are usually cheaper than Natural Diamonds of similar size and quality. The cost can vary, but on average, lab-grown diamonds are around 30-40% less expensive than natural diamonds.
Colorless Natural Diamonds are the most common and highly valued, as they are considered the purest and rare. The cost of colorless Natural Diamonds can vary widely depending on the diamond's specific characteristics, such as its carat weight, cut, clarity, and color grade. As a general rule, the larger the diamond, the more expensive it will be.
Lab-grown diamonds are created in a controlled laboratory environment, using one of two methods: High Pressure High Temperature (HPHT), or Chemical Vapor Deposition (CVD). HPHT lab-grown diamonds are created by mimicking the high pressure and high temperature conditions found in the Earth's mantle, where natural diamonds form.
CVD lab-grown diamonds are created using a chemical vapor deposition process, where a diamond seed is placed in a chamber and a mixture of gasses is introduced. These gasses are then broken down by a high-energy plasma, and the carbon atoms in the gas deposit onto the seed, forming a diamond crystal.
Natural diamonds are formed deep within the Earth's crust, typically at depths of more than 150 kilometers, and brought to the surface by volcanic eruptions. Most natural diamonds are mined from kimberlite and lamproite pipes, which are formed by volcanic eruptions that brought diamonds to the surface.
Diamonds are typically mined in open pits or underground mines, using large excavating equipment and diamond recovery technology. The mining process can be quite complex and can take several years to complete.

Produced in a controlled environment, lab-grown diamonds share identical chemical properties with natural diamonds. Because they share the same crystal structure, they have indistinguishable properties from a natural diamond. Lab-grown diamonds also have the same scratch resistance as a natural diamond as they both score 10 on the Mohs hardness scale.

Lab-grown diamonds cost less per carat than natural diamonds. The rarity of a natural diamond contributes to its higher price.

You may hear these diamonds referred to as lab-made, lab-grown, lab-created, synthetic, and cultured which can all describe diamonds made in a laboratory.

Since lab-grown diamonds are chemically and physically identical to natural diamonds, they are not regarded as fake. Throughout history, fake diamonds have been made of glass and carry no value. Plastic, glass, or white gemstones do not possess the properties of a diamond that create its infamous sparkle and scratch resistance.

The lab-diamond crystal is grown in a highly controlled environment. One method, called HPHT, begins with carbon placed under a high pressure, high temperature environment resulting in a diamond crystal. Another common method is called Chemical Vapor Deposition, CVD. This method begins with a seed crystal and develops the diamond using gas and heat to grow the crystal. Once a lab-grown diamond is complete, it still must be cut and polished.
