Welcome to Forever JH Diamond

Our JH Diamonds are the most perfect man-made diamond clones ever created. They refract light into perfect “hearts and arrows”, and they have superb fire and brilliance. They closely match the optical and physical properties of expensive natural diamonds as their clarity and color are perfect on their respective scales. In almost all measurable tests, our JH Diamond simulants match or are superior to natural diamonds.

In fact, our JH diamond is so close to natural diamond that most gemologists require scientific testing equipment to tell the difference. Yet, for all their glittering beauty, JH Diamond only cost a fraction of what natural diamonds do, allowing you to own magnificent fine jewelry at a fair and realistic price.

We invite you to learn more about lab-created diamonds in general and also our diamond in our Diamond Education. Here you can learn everything you need to know about our JH Diamond; not only the science and technical specifications of our creations, but also the history and story of man-made diamonds.

Customer feedback

It looks really great, better than my real diamond pendant. When I put
these two next to each other, JH diamond looks much better than my real one.

I am going to wear it to my Christmas dinner and New year party.
Thank you for answering so many my questions. You are very helpful....
