LAB GROWN DIAMONDS

  • Lab Grown Diamonds are real man-made Diamonds. These Lab Grown Diamonds are created in Lab and have the same physical, chemical, and optical properties as Natural Diamonds..
  • Lab Grown Diamonds have gained increased popularity in recent times. Our Lab Grown Diamonds are CVD (Chemical Vapor Deposition) (type IIa) Diamonds that are specifically engineered to have a high level of purity, with little to no impurities or defects in the crystal lattice structure.
  • In today's rapidly changing Diamond Industry, GURUDIAM use of cutting-edge CVD Technology in-house has made it possible to replicate a perfect Diamondâs natural growth in highly controlled environments.
  • The CVD process for Lab Grown Diamonds is highly versatile, and this allows the production of Diamonds in a variety of shapes, sizes, and colors. With the added benefits of being Sustainable, and often more affordable.
  • The CVD Lab Grown Diamond process has been perfected in India, where the CVD Diamond technique is the best in the world.
