Diamond Certification

Diamond Certification at Voogmechic

When you purchase from Voogmechic, your lab-created diamond jewelry is accompanied by an International Gemological Institute (IGI) certificate. IGI is one of the most respected gemological laboratories in the world, with offices in over 20 countries. Every certificate includes a unique verification number and provides a detailed breakdown of the diamond or gemstone’s quality. The report covers all four Cs—carat, cut, color, and clarity—as well as symmetry, polish, proportions, and fluorescence. IGI’s reputation for consistency and precision ensures that the stone you receive has been independently graded by professional gemologists using advanced equipment.

What Is a Diamond Certificate?

A diamond certificate, also called a grading report, is issued by an independent laboratory to confirm a diamond’s authenticity and quality. It records key characteristics such as shape, measurements, weight, clarity, color, finish, and overall cut evaluation. With this document, buyers can shop with confidence, knowing the stone’s attributes are verified by experts.

About GIA

The Gemological Institute of America (GIA) is widely considered the pioneer of diamond grading and the authority that introduced the 4Cs. A GIA report includes full details of polish, symmetry, fluorescence, and proportions, together with a laser inscription for verification. Each GIA certificate also carries a distinct serial number, which can be validated through the GIA website.

About GCAL

The Gem Certification & Assurance Lab (GCAL) is known for its grading guarantee. Their certificates include a unique optical fingerprint of the diamond, along with light performance and 360° imaging. GCAL also introduced the 8X cut grading standard, which evaluates eight aspects of cut precision, including brilliance, fire, and symmetry.
