RAGAZZA DAII (Diamond Artificial Intelligence Index) is a diamond quality model that combines Marcel Tolkowsky’s brilliant cut proportions with modern AI analysis. Its main purpose is to transform scattered and complex data from diamond certificates into a single, quantifiable, and easy-to-compare quality score: the DAII Score.

Emerald cut diamonds are celebrated for their elegant, sleek, and vintage silhouettes. Unlike the intense fire and scintillation sought in round brilliant diamonds, the emerald cut prioritizes clarity, clean lines, and an architectural beauty characterized by its "hall of mirrors" light play.

Lab grown diamonds (LGD) have expanded rapidly over the past decade and are now widely used in engagement rings and fine jewelry. As demand increases, one of the most common questions buyers face is whether to choose a GIA or IGI certificate.

Family Jewelry is a popular new family keepsake in Europe and America, designed exclusively for fathers, mothers, and babies. RAGAZZA offers bespoke designs — from pendants and rings to complete sets — creating a one-of-a-kind family emblem that turns love into eternity.
