Proprietary AI Rating

The ROSI Score

ROSI is RockHer's proprietary AI-driven evaluation engine — built to analyze diamonds at a depth most buyers never see. It measures and weights 30 distinct performance and value parameters, including optical behavior, structural proportions, grading factors, and real-time pricing efficiency. This diamond earns a ROSI score of $[selectedSingleDiamond.rosi_score] out of 100.

The carat is the unit of weight of a diamond. Carat is often confused with size even though it is actually a measure of weight. The visual below illustrates the actual millimeter footprint of this $[selectedSingleDiamond.visual_carat]ct diamond compared to a standard US Dime to give you a true real-world sense of scale.

US Dime
17.91 mm
$[selectedSingleDiamond.dim_width] mm ($[selectedSingleDiamond.visual_carat] Ct)

The cut refers to the angles and proportions of a diamond. The cut of a diamond - its form and finish, its depth and width, the uniformity of the facets - determines its beauty. The skill with which a diamond is cut determines how well it reflects and refracts light.

A diamond's clarity refers to the presence of impurities on and within the stone. When a rough stone is extracted from carbon deep beneath the earth, tiny traces of natural elements are almost always trapped inside and are called inclusions.

Color is the natural color visible in a diamond and does not change over time. Colorless diamonds allow more light to pass through than a colored diamond, releasing more sparkle and fire. Acting as a prism, a diamond divides light into a spectrum of colors and reflects this light as colorful flashes called fire.
