Do lab grown diamond look different?

To the naked eye, lab diamonds look exactly the same as the mined ones to even the most trained and experienced jewelers and gemologists. Because synthetic diamonds have the same physical and chemical properties as natural diamonds that cannot be discerned by the naked eye alone. And lab created diamonds cut and polish specifications, like natural diamonds, are also divided according to the 4Cs. Therefore, to distinguish, experts need to use specialized equipment to decipher the physical and spectral differences with natural diamonds.
What is high pressure and high temperature?

HPHT, the full name is High Pressure High Temperature, that is, high temperature and high pressure. To be clear, the term HPHT has two concepts in diamonds: HPHT lab-grown diamond and HPHT treated processed. For example, brown diamonds can be turned into yellow or colorless through HPHT treatment.
