What is a lab-grown diamond?

    • A lab-grown diamond is a diamond. It is chemically, optically, and physically identical to a mined diamond. The difference is where they are grown.  Mined diamonds are formed in the earth's mantle, while lab-grown diamonds are grown above ground, in a laboratory.
    • A lab-grown diamond is NOT a simulant (like a cubic zirconia)

    What are the benefits of a lab-grown diamond?

      • Lab-grown diamonds are absolutely, 100% conflict and blood free.
      • Lab-grown diamonds require zero mining.
      • Lab-grown diamonds cost up to 40% less than comparable mined diamonds, which means you can get a bigger, better diamond, or opt to save money.
      • Lastly, lab-grown diamonds are among the most pure diamond on earth; type IIa. Only 2% of mined diamonds are of this quality.                                                                  

        What's the difference between a lab-grown diamond and a mined one?

          • The main difference is in where they are grown. A mined diamond is formed in the earth’s mantle over millions of years. Lab-grown diamonds are grown above ground, in a laboratory, over a period of time. The growth process typically takes about two months, but can take as long as a year for some gemstones. Other differences include the benefits of lab-grown; mined diamonds are more expensive (when compared to a lab-grown of the same quality), mined diamonds are more detrimental to the environment, and 98% of mined diamonds are less pure than their lab-grown counterparts.

          How is a lab-grown diamond made?

            • There are two ways to grow a diamond above-ground: HPHT and CVD. Both processes produce beautiful, pure diamonds.
            • HPHT (High-Pressure-High-Temperature) mimics the environment below the earth by placing a diamond seed in a growth chamber of extreme temperatures and pressure, as the name suggests. These parameters have to be maintained throughout the growth process, or else the growth may stop or cause the diamond to become heavily included. If all goes well, the rough diamond is then taken to be cut and polished.
            • CVD (Chemical Vapor Deposition), in this process, methane gas is activated using microwave energy to an extreme temperature, causing it to break and release carbon atoms. This carbon then deposits onto a diamond substrate, where it slowly grows layer by layer, atom by atom, as a crystal.

            How long have lab-grown diamonds been around?

              • Since the 1950’s, when they were first created by General Electric for industrial purposes. Not until recently did those gemstones become gem quality, similar to how not all mined diamonds are gem quality (in terms of the 4 C’s).

              How can you tell a difference between a lab-grown diamond and a mined one?

                • Not even a trained and experienced gemologist or jeweler can diagnostically separate lab-grown diamonds from mined ones. There are tools out there to help in determining whether a stone may or may not be a laboratory-grown diamond, however, the best and most accurate method is by sending them to a 3rd-party lab, like the GIA, IGI, or GCAL. 
                • As lab-grown diamonds ARE diamonds, they do test positive on a diamond tester.

                Is a lab-grown diamond as hard as a mined one?

                  • Yes! The Mohs scale of hardness characterizes scratch resistance of various minerals through the ability of a harder material to scratch a softer material. The scale is 1-10 (10 being the hardest). A diamond is a 10. Gemstones like rubies and sapphires are 9, and emeralds are an 8. However, the scale isn’t completely linear; a diamond (10) is still four times as hard as a ruby or sapphire (9). While a diamond is at the top of the scale, meaning nothing below it on the scale can scratch it, that doesn’t mean it’s indestructible. It can still break if hit very hard in the right place. Always take care when wearing your fine jewelry, even diamonds!

                  Do you use lab-grown diamonds in your side stones?

                    • Absolutely! We are one of the very few lab-grown retailers to use only 100% lab-grown diamonds in all of our jewelry, including the tiny side stones. Most of our competitors use “recycled” mined diamonds. We think this is a no-no. We take great pride in not only offering lab-grown side stones, but the best quality side stones you’ll find. Ours are VVS quality and D-G in color. For comparison, the industry standard is I clarity range (included) quality and H-J in color.

                    Do you sell any diamond alternatives, like hybrids or simulants?

                    • No, we take pride in selling only laboratory-grown diamonds and colored gemstones. We do not sell any simulated diamonds like cubic zirconia (CZ), hybrids or anything closely resembling a simulant.

                    Recycled Precious Metals

                    • At Soha Diamond Co., we believe that gold, platinum, palladium, silver, and other precious metals should be mined and refined in a sustainable manner that respects the needs of humanity and our environment. We accept only specific, branded gold bars or grain in our production operations and all materials used in production are recycled internally. In addition, we require that our manufacturers, suppliers, and business partners maintain policies and procedures that mandate social and environmental responsibility, thereby certifying our 100% recycled content.

                    What diamond sizes and shapes do you have?

                    • We offer diamonds in a variety of sizes and shapes. If you have your heart set on a specific size and/or shape that you do not see listed on our website, please contact us and one of our in-house gemologists will help you find what you’re looking for!

                    • Additionally, please refer to our mobile-friendly interactive virtual try-on where you can see different ring styles, shapes (cut), and sizes of lab-grown diamonds in carats (ct.) or millimeters (mm) on an interactive, virtual hand.

                     Do your diamonds come with a grading report?

                    • Yes! All of our center stone diamonds will come with their accompanying Grading Report, either from IGI or GCAL. These reports will show the identification of the lab-grown diamond, grade the diamond on its four C's (carat weight, color, cut and clarity), plus show all measurements, proportions, symmetry, and polish.
