Clarity, as defined by the prestigious Gemological Institute of America (GIA) in its 4C grading system, refers to the presence of natural inclusions, internal characteristics such as microscopic crystals, gas bubbles, or tiny fractures - as well as surface blemishes on a diamond. These formations develop over millions of years deep within the Earth, serving as a unique imprint of the diamond’s geological history. The fewer such imperfections, the rarer, more transparent, and more valuable the diamond becomes. GIA assesses clarity under 10x magnification, classifying diamonds with a precise scale that determines their exceptional quality and worth.

We take immense pride in the fact that all BELLER diamonds belong to the prestigious VVS1 (Very Very Slightly Included) category, a testament to their extraordinary collector’s value and uncompromising brilliance.

Cut, according to the 4C grading system, refers to the way a diamond has been shaped and polished, directly influencing its brilliance, proportions, and ability to reflect light. It is the only factor in the 4C system that is entirely dependent on human craftsmanship. Precision cutting can either maximize a diamond’s radiance or diminish its sparkle.

A perfectly cut diamond reflects light from one facet to another, directing it back through the crown and creating the mesmerizing effect known as ‘brilliance’ and ‘fire’. Even a diamond with flawless clarity and exceptional color will not shine to its full potential if its cut is not executed to perfection.

At BELLER, we believe that cut is the heart of a diamond,  bringing it to life, shaping its character, and unlocking its unparalleled brilliance.

Carat, in the 4C scale, is determined by the weight of the diamond, measured in carats (ct). One carat is equal to 0.2 grams, roughly the weight of a single grain of sugar. While larger diamonds are rarer and more valuable, the weight itself does not dictate their quality. Equally important are the cut, color, and clarity, which influence the optical appearance of the stone.

Two diamonds of the same weight can appear quite different. If a diamond is poorly cut and too flat, it may seem larger but won’t reflect light well. On the other hand, a perfectly cut diamond with a smaller weight may shine much more intensely than a larger diamond with poor proportions.

In the world of luxury jewelry, carat is a number, but brilliance is an art.

Color, in the 4C scale, refers to the natural hue of a diamond, or more accurately, the absence of it. The most valuable diamonds are colorless because the purity of their structure allows light to pass through and reflect freely, creating an intense brilliance.

The Gemological Institute of America (GIA) classifies diamonds on a scale from D to Z, with D representing colorless stones: the rarest and most sought-after diamonds. All diamonds used by BELLER are distinguished by the highest color quality, ranging from D to F. 

Aware of their value, we carefully select stones that tell the story of light in its purest and most beautiful form.
