Why purchase certified loose diamonds?

Before purchasing a diamond, it is critical to verify that it has undergone an unbiased and professional examination through an independent and accredited certification company. This protects you from paying for overrated and falsely advertised diamond quality.

What is a Diamond Certificate?

A diamond certificate, also called diamond grading report, diamond dossier®, Diamond Full Certificate, and Hearts & Arrows Diamond Report, is a report created by a team of certified gemologists. The diamond is evaluated, measured, and scrutinized using trained eyes, a jeweler’s loupe, a microscope, and other industry tools. A completed certificate includes an analysis of the diamond’s dimensions, clarity, color, polish, symmetry, and other characteristics. Many round diamonds will also include a cut grade on the report.

San Diego Jewelry Brokers Diamonds Are Certified

Every certified loose diamond sold by San Diego Jewelry Brokers has been analyzed and graded by either the Gemological Institute of America (GIA) or the European Gemological Institute (EGL USA). These two laboratories are among the most respected laboratories in the diamond industry and are known for their consistency and unbiased diamond grading systems. Diamonds that are accompanied by these grading reports are the most highly valued in the industry.
