20-30 minutes

Issuance of a certificate or opinion

Stone examination process

In order for the process to be fast and high-quality, we use modern equipment. The characteristics of the study are determined by international standards.

1

We determine the naturalness of the mineral

There are natural minerals, and there are those grown in a laboratory.

To determine naturalness, we analyze the absorption of UV radiation. This will help weed out Type IIA diamonds that are likely lab-grown.

We use the tester SYNTHETIC DIAMOND SCREENER II OF PRESIDIUM
2

We check the authenticity

This technology is the latest technological advancement to reliably verify the authenticity of diamonds and moissanites.

The high expansion of the thermal imager and electrical conductivity prevents damage to the stones during testing.

We use the tester DIAMOND AND MOISSONITŠ• TESTER SAM OF PRESIDIUM
3

We identify the origin

So we can distinguish diamonds from other types and identify diamonds grown in the laboratory by CVD and HPHT methods, Moissanites, Fianites, Glass, etc.

We have the ability to test jewelry inlays and stones unmounted and in jewelry. The device scans stones weighing from 0.02 ct or more.

We use the tester ARTIUM BY OGI SYSTEMS
4

We analyze the faces

The quality of the cut is the most important factor that affects the brilliance of a diamond.

Like tiny mirrors, the diamond's facets are precisely sized and proportioned, allowing the diamond to gather and reflect light as much as possible.

This is how we learn complete information about the stone: weight, diameter, angle and height of the crown, angle and height of the pavilion, etc.

We use SCANOX ZOOM BY OGI SYSTEMS
5

We make high-quality video and 3D-photos

We make stunning HD images and 360-degree videos of precious stones or jewelry.

You will receive these photos and videos after certification.

We use DIAPIX BY OGI SYSTEMS
