Why Opt for Lab Created Diamonds?

Lab created diamonds offer tremendous value. If you’re looking for diamonds that fall within your budget, they provide affordable options as opposed to mined diamonds. Not to mention, they do so without compromising on quality and size.


Engineered diamonds feature similar optical, chemical, and physical properties as natural diamonds, allowing them to offer the highest quality.

No Mining

Lab created diamonds don't require mining, preventing any environmental damage.

What are Lab created diamonds?

Lab created diamonds, commonly known as engineered diamonds, man-made diamonds, and cultured diamonds, are produced or grown using cutting-edge technology in a highly controlled environment. Using this equipment, experts mimic the natural procedure that allows for the production of earth-grown diamonds in the mantle beneath the earth's crust. Engineered diamonds also contain real carbon atoms that are arranged in the same way as mined diamonds. Since they are made from the same material, carbon, they show the same chemical and optical properties.
Diamond USA features a variety of lab-grown diamonds. Our diamonds are also available in various colors, including unique shades that are hard to find in mined diamonds, such as vivid yellow. Also, unique colored diamonds come with a reasonable price tag compared to natural diamonds.

How are Man-Made Diamonds Made?

Diamond USA prepares lab diamonds from the tiny carbon seeds of mined diamonds. Advanced technology, like the special deposition process, called CVD or extreme heat and pressure, replicates the natural process that creates mined diamonds. At Diamond USA, some engineered diamonds are processed under pressure and heat treatment after they’re created. Engineered colored diamonds are made by introducing a small number of specific residue elements during the growth stage of man-made diamonds. This is the same way naturally grown diamonds end up colored.

But in fancy and white-colored diamonds, the number of introduced trace elements may differ from that of naturally growing diamonds. An engineered diamond can only be identified using special methods and equipment to indicate minor differences in crystal growth and trace elements.

What are the Advantages of Lab created diamonds?

Diamonds produced in laboratories offer the same appeal and look as natural diamonds. Both diamonds have the same chemical and physical properties and experience the same pressure and temperature conditions. However, the creation of lab created diamonds doesn’t involve questionable ethical procedures that are commonly used to mine diamonds. Plus, engineered diamonds offer much better quality since they’re produced in a thoroughly monitored process and controlled environment. Some of the benefits of man-made diamonds are:

  • Minimal to no defects
  • More attractive appearance due to higher purity and brighter quality
  • Cost-effective
  • No environmental damages
  • Offer unique colors that are not found in nature, allowing you to benefit from unique pieces.
  • Companies offering lab created diamonds also offer pretty ring settings
  • Engineered diamonds require a sustainable process for production, such as chemical vapor deposition (CVD). This allows companies to keep up with demand without impacting the environment and sacrificing quality.

What are Sustainably Produced Diamonds?

Diamond USA has been producing sustainable and beautiful diamonds. They are sustainable lab created diamonds since they don’t use harmful techniques that pollute the environment. We also use technology that doesn't cause harm, like the mining procedure, making man-made diamonds a better option to protect the environment.

How are Engineered Diamonds Graded and Certified?

At Diamond USA, all lab created diamonds are made with the same process. After production, we send them to a gemological laboratory to get them certified.

Grading Engineered diamonds is similar to the process of grading mined diamonds. We pay great attention to the colors, carat, clarity, and cut of a gemstone. Clarity is an important factor that limits defects and cracks in the diamond and improves appearance. The cut is another factor that refers to the brilliance and finish of the diamond, while carat is the measurement of the gemstone's weight and size. Our team inspects each diamond and ensures that they offer the highest quality.

Diamond rings are the best gift you can give someone. However, purchasing a beautiful diamond ring with fantastic accents and a center diamond can cost you a lot. Affordable lab created diamonds make it easy to show your spouse how much you cherish them. You’ll be able to gift an exceptional piece that falls within your budget and doesn’t harm the environment.

Lab-Created Diamonds vs. Diamonds Stimulants

It’s important to understand the difference between diamondstimulants and lab-created diamonds. Like moissanite and cubic zirconia,Diamond stimulants look similar to diamonds but don't have the same carboncomposition. Therefore, stimulants don't offer the same physical and chemicalproperties as natural diamonds and sell at much lower prices compared to engineereddiamonds. It’s also easy to differentiate stimulants from lab-created or naturaldiamonds.

Lab-created and natural diamonds have thermic conductivity propertiesthat help experts identify them using a hand diamond checker, differentiatingthem from cubic zirconia. Some natural or lab-created diamonds can mistakenly beidentified as moissanite when using specific diamond testers. This is because theyhave similar electrical conductivity properties. A gemologist can easily identifythe moissanite and diamond just by looking. This is because of their differentrefractive properties, as diamonds are single refractive, and moissanite is doublerefractive.
