Key Takeaways

  • Nexus diamonds have a patent formula composition instead of a carbon element.
  • Authentic Diamond Nexus doesn’t get cloudy.
  • Diamond Nexus are cheaper than actual diamonds.
  • Nexus diamonds are flawless.
  • The simulant has a specific proprietary formula and extra coating of materials making the surface hard. As such, the diamond doesn't get cloudy over a long period. Keep reading to learn what is Diamond Nexus, its characteristics and why you should choose a diamond alternative.

    Let's dive in!

    What is Diamond Nexus?

    Diamond Nexus is a diamond alternative. It is a diamond created in the lab that imitates the different chemical compositions of a diamond closely without having the carbon element. 

    The Nexus Diamond is divided into three artificial diamonds categories:

    • Diamonds- Companies grow them in a controlled environment in the labs.
    • Diamond simulants- They include Nexus Diamonds alternatives and moissanite. Companies make them in labs. Nexus Diamond's chemical structure is a proprietary formula and patented coating material, while moissanite has silicon carbide. 
    • Costume jewelry simulants, including cubic zirconia (companies make them in labs), and cubic zirconia has zirconium dioxide as the chemical composition. 

    Nexus Diamond looks like real diamonds but has a different chemical makeup and is cheaper. The diamonds are perfect for making engagement rings, wedding bands, and jewelry. 

    Characteristics of Nexus Diamonds

    People characterize diamonds based on color, carat, clarity, and cut. Let's look at each:


    The American Gem Society Color Grade has a scale from 0(colorless) to 10(light brown or light yellow), showing where diamond colors fall. The scale also has letters ranging from D to Z. D means it's completely colorless, while Z is light yellow. Most lab made diamonds use D as the best color. 

    Nexus Diamond company grades their diamonds' color as D, meaning colorless. A lot of diamond simulants fall into this category. 


    The feature that gives a diamond the sparkly effect is the cut. The most precious real diamonds can look dull without a proper cut. Nexus diamond alternatives have a variety of cuts, from round brilliant to princess cuts and many more.

    Capetown Diamond Museum states that the most popular diamond cut is Round brilliant with 57 facets. Other famous diamonds include the Cushion Cut Diamond and Princess Cut Diamonds, which you can find in Nexus diamonds. 


    Diamond Nexus are flawless diamonds because they are lab-made diamonds. You measure the clarity of a diamond depending on the imperfections that affect any gem's natural beauty. Diamonds Clarity Scale run from Flawless to Include. Include means that you can locate defects and their location quickly. On the other hand, flawless means that gem experts find it challenging to give negative reviews.


    Diamond carat weight is a standard indicator that shows the size of a diamond. Large-sized mined diamonds are rare. However, companies can manipulate the size of lab-created diamonds. You will find Diamond Nexus in different sizes, including big and small.

    Why Choose a Diamond Alternative?

    Natural diamonds are the hardest gemstones and are significantly pricy. Due to their beauty and rareness, people have been using them as engagement rings for years. With the rise in popularity of diamond alternatives, people are starting to rethink buying mined diamonds. But why? Let's look at some of the reasons:


    Natural diamonds are valuable but have more flaws than lab-grown diamonds. Companies can manipulate the growth of artificial diamonds in controlled environments hence fewer flaws.

    Concern About the Source

    Diamond mining has been the cause of the mining industry's violence, exploitation of workers, and environmental devastation. The miners are tortured, beaten, and sometimes murdered. Additionally, people exploit workers, kids, and communities to harvest natural diamonds. These workers work in unsafe conditions with no proper tools and safety equipment. Diamond mining causes severe damage to water and land, leading to deforestation and soil erosion.

    The Kimberly system that claims to have resolved conflicts in diamond mining still overlooks other issues. The system ignores poverty, violence, human rights abuses, and environmental degradation.


    Natural diamonds are rare. Their cost increases as the clarity, color, and carat increase. The average price of diamonds is $1500(0.5 carats) to $21000(two-carat diamond). Factors such as clarity, color, cut, carat, diamond fluorescence, and shape of the diamond affect the cost. With the high price of natural diamonds, people are seeking lab-grown diamonds because they are cheaper, internally flawless, and almost like the real deal.

    The Best Alternative to Natural Diamonds

    The best alternative for natural diamonds is Moissanite and lab-grown diamonds because they come close to variety, closeness, and appearance. Due to their popularity, moissanite and lab-grown diamonds come in various cuts and styles of your choice. Jewelry stores will use these alternatives as engagement rings and jewelry: Moissanite and cubic zirconia.

    The cheapest diamond alternative is cubic zirconia or simulated diamonds, which are easy to find. However, they are soft on the Mohs hardness scale and do not resist dirt well. A Nexus diamond, moissanite, and cubic zirconia are great alternatives depending on your budget.

    Is Diamond Nexus Worth It?

    Yes, Diamond Nexus is worth it since you pay a quarter of a natural diamond's price. Mohs scale shows that the Diamond Nexus has a hardness of 9.2. As such, your perfect engagement ring or other jewelry pieces won't scratch or damage easily. The diamonds are also flawless, which means that even a gem expert finds it hard to find flaws in lab-made diamonds.

    Does a Diamond Nexus Get Cloudy?

    No, a real Diamond Nexus doesn't get cloudy with time. The protective layer on the stones prevents the accumulation of grime or dirt over time. If your engagement ring gets cloudy, it means that the quality is substandard.

    Should I Go With Moissanite or Nexus Synthetic Diamonds?

    You should go with moissanite or Nexus synthetic diamonds, depending on some factors. First, a Diamond Nexus is cheaper than moissanite. Picking between the two depends on your budget. For example, when it comes to hardness on a Moh's scale, Moissanite stone is at 9.5 while Diamond Nexus is at 9.2.

    Are Diamond Nexus Good?

    Yes, Diamond Nexus are good even though they do not have the same chemical properties as natural diamonds. Diamond Nexus are lab-grown diamond simulants. They are also cheaper and flawless.

    Can You Differentiate a Diamond Nexus From a Mined Diamond?

    Yes, you can differentiate a Diamond Nexus from a mined diamond with the help of experienced jewelers or gemologists. These experts can tell if a stone is lab created since only some natural diamonds are perfect. They will test to see if the stone has a crystallized carbon structure. If it is not, that means it's not a natural diamond since Nexus diamond composition is a patented formula.

    Can You Differentiate Between Moissanite and Mined Diamond?

    Yes, you can differentiate between moissanite and mined diamonds because they are not similar in appearance. The refractive quality will help you learn the difference. Moissanite will refract multiple colors. Still, some moissanite qualities resemble a natural diamond, such as clarity and cuts.
