A report issued by the IDIC laboratory provides clear details of the item that accompanies it, giving confidence to both the buyer and the seller.

IDIC diamond report give an accurate assessment of a diamond cuts, color, clarity and carat weight according to strict international standard. 

IDIC screen every diamond using state of the art technology to determine naturally mind, laboratory grown or simulant origin.

IDIC will not issued reports for diamonds non permanent treatments.

Some examples of stone testing methods are:

  • Petrographic analysis: This test involves examining the mineral composition, texture, structure, and origin of the stone using a microscope or other instruments. It can reveal important information about the stone’s formation, weathering, alteration, and suitability for various uses.
  • Absorption test: This test measures the amount of water that a stone can absorb when immersed in water. It indicates the porosity and density of the stone and its resistance to frost damage. The test involves drying test specimens of the stone in a ventilated oven for 48 hours and then weighing them.  The specimens are then submerged in water for 48 hours and weighed again. The absorption value, expressed as a percentage, is the difference between the dry wight and wet saturated weight.
  • Hardness test: This test measures the resistance of a stone to scratching by another material. It can indicate the durability and wear resistance of the stone. The most common method is to use Mohs scale of hardness, which ranges from 1 (softest) to 10 (hardest). A harder material can scratch a softer one, but not vice versa. For example, a diamond (Hardness 10) can scratch quartz (hardness 7), but quartz cannot scratch diamond.
  • Compressive strength test: This test measures the maximum load that a stone can withstand before failure under compression. It indicates the load-bearing capacity and structural stability of the stone. The test involves applying a gradually increasing load on a cube or cylinder of stone until it cracks or breaks. The compressive strength is calculated by dividing the maximum load by the cross-sectional area of the specimen.
