For many years, diamonds have been the most coveted gemstone due to their durability, rarity, and sparkle. However, the rise of man-made diamonds has given buyers a more ethical and affordable option while still maintaining the beauty and quality of natural diamonds. In this article, we will discuss the top man-made diamonds available in the market today and why they are worth considering.

  1. Pure Grown Diamonds

Pure Grown Diamonds is one of the leading best man made diamonds NZ companies that uses a process called Chemical Vapor Deposition (CVD) to create lab-grown diamonds. Their diamonds are made from a small diamond seed that is placed in a vacuum chamber and then exposed to a carbon-rich gas. The gas then heats up and breaks down, causing the carbon atoms to stick to the seed and form a diamond.

What sets Pure Grown Diamonds apart is their commitment to sustainability. Their diamonds are grown using renewable energy sources and recycled water, which greatly reduces their carbon footprint. In addition, their diamonds are certified by the International Gemological Institute (IGI) and have the same physical and chemical properties as natural diamonds.

  1. MiaDonna

MiaDonna is another popular man-made diamond company that offers lab-grown diamonds in a variety of cuts and colors. They use a process called High Pressure High Temperature (HPHT) to create their diamonds, which simulates the conditions in which natural diamonds are formed.

MiaDonna is also committed to sustainability and ethical practices. They donate a portion of their profits to the Greener Diamond Foundation, which helps fund education and development projects in diamond-mining communities. Their diamonds are also certified by the IGI and have the same quality and beauty as natural diamonds.

  1. Diamond Foundry

Diamond Foundry is a Silicon Valley-based company that uses renewable energy sources to grow their diamonds in a plasma reactor. Their process is unique because it produces diamonds that are both eco-friendly and of the highest quality. Their diamonds are certified by the Gem Certification and Assurance Lab (GCAL), which is known for its strict grading standards.

What sets Diamond Foundry apart is their commitment to transparency. They provide a unique diamond identification number that allows customers to track their diamond’s origin and history. This ensures that their best man made diamonds are conflict-free and ethically sourced.


Man-made diamonds are becoming increasingly popular due to their affordability, sustainability, and ethical practices. Companies like Pure Grown Diamonds, MiaDonna, and Diamond Foundry are leading the way in producing high-quality lab-grown diamonds that are virtually identical to natural diamonds. These diamonds not only offer buyers an alternative to traditional mined diamonds, but also provide a more ethical and sustainable option for those who want to make a positive impact on the environment and society.
