Screening & Testing

A screening procedure indentifies a simulant diamond, a synthetic or lab grown diamond, or a natural diamond.

There are three types of diamonds available in the market.

  • Simulant
  • Synthetic
  • Natural

Simulants and synthetic diamonds differ hugely in terms of value from natural diamonds. Simulants are stones that only resemble diamonds, (example cubic zirconia (CZ), moissanite, zircon etc.)

Synthetic diamond is also known as Lab grown diamond. To the naked eye or with 10x or higher magnification, a lab grown diamond and a natural diamond appear identical since they both have the same chemical composition and hardness but differ hugely in terms of value, example CVD (Chemical Vapor Deposition) and HPHT (High Temperature High Pressure).
