THE FULL REPORT INCLUDES

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:

1. Simulant
2. Synthetic
3. 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).

In our rough diamond report, we provide the following information :

1. Authenticity and Quality of Rough Diamond.
2. Weight, colour and clarity.
3. With or without a polished surface.
4. Transparent to opaque.
5. Sawable or Makable.

THE FULL REPORT INCLUDES

Each diamond is tested to confirm whether it is Natural, Laboratory Grown, or Simulant. If it is found to be Lab-Grown, a Lab Grown Diamond Report will be issued with the clear wording on the report “LAB GROWN”.All the details like weight, measurements, colour, clarity, cut grade, symmetry, polish, fluorescence, and shape will be mentioned in the report.
