Diamond Verification

Our team of skilled gemologists, armed with specialized tools, meticulously measures the weight and dimensions of diamonds, examining key quality attributes such as cut, color, and clarity. The Pandia diamonds go through a thorough independent check to carefully assess their quality characteristics and origin. A diamond certificate or grading report, expertly issued by an independent gemology lab, provides a detailed assessment of the diamond's quality. Importantly, The Pandia diamonds proudly bear certifications from the world's foremost gem grading lab, IGI. Feel free to reach out to us if you'd like to request a digital copy of a diamond's lab certificate.

What Features Define The Quality Of A Diamond?

One of the interesting things about diamonds is that not all diamonds are created equal. In fact, every diamond is unique. Diamonds come in many sizes, shapes, colors, and with various internal characteristics. Jewelry professionals use a systematic way to evaluate and discuss these factors. Otherwise, there would be no way to compare one diamond to another. And there would be no way to evaluate and discuss the qualities of an individual diamond. Diamond professionals use the grading system developed by GIA in the 1950s, which established the use of four important factors to describe and classify diamonds: Clarity, Color, Cut, and Carat Weight. These are known as the 4Cs. When used together, they describe the quality of a finished diamond. The value of a finished diamond is based on this combination.

How Are The Quality And Value Of Diamonds Classified?

Diamond quality is assessed based on a set of criteria commonly known as the "Four Cs": Carat weight, Cut, Color, and Clarity. These factors help determine the overall quality and value of a diamond. 

Carat Weight: Carat is the unit of measurement for a diamond's weight. Larger diamonds are generally more valuable, but the overall value also depends on the other three Cs.

Cut: The cut refers to how well a diamond has been shaped and faceted. It's not just about the diamond's shape (round, princess, emerald, etc.) but how well it interacts with light. A well-cut diamond will reflect and refract light in a way that enhances its brilliance.
     ● Excellent Cut: Reflects most light that enters, creating maximum sparkle.
     ● Very Good Cut: Reflects nearly as much light as an excellent cut but may be less expensive.
     ● Good Cut: Reflects a majority of the light that enters but may not be as brilliant as a very good or excellent cut.
     ● Fair and Poor Cuts: May allow light to escape, resulting in less brilliance.

Color: The Gemological Institute of America (GIA) grades diamonds on a color scale from D (colorless) to Z (light yellow or brown). The less color a diamond has, the more valuable it is. Clarity: Clarity refers to the presence of internal or external flaws, known as inclusions and blemishes, respectively. The GIA grades clarity on a scale from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions and/or blemishes visible to the naked eye).

What Is The Form Or Structure Of A Diamond?

Diamond shape refers to the overall outline of a cut diamond when viewed from the top. It is distinct from the cut, which pertains to the diamond's facets and interaction with light. Common shapes include the classic round brilliant, the elegant princess, the rectangular emerald and Asscher cuts, the elongated marquise and oval shapes, the square radiant, and the unique pear and heart shapes. Each shape contributes to the diamond's aesthetics, and personal preferences often guide the choice of shape when selecting a diamond for jewelry.
