VERY GOOD
Unique and rare gems symbolizing love and eternity, mined from nature.
These diamonds have slight color that are visible, which tends to be more noticeable in diamonds over 1 carat.
Slightly included. The inclusions are detectable under 10x magnification, but are not very visible to the naked eye.
High quality cut that reflects almost as much light as an excellent cut diamond.
GIA (Gemological Institute of America) stands at the pinnacle of credibility in diamond certification. Renowned for its uncompromising standards and precise grading, GIA ensures each diamond meets the highest level of quality. A GIA certificate is more than a report - it’s a mark of trust, excellence, and lasting value.
IGI (International Gemological Institute) is a globally recognized diamond grading authority known for its efficient and flexible evaluation standards. It uniquely includes the 'Hearts and Arrows' cut in its reports, offering a more detailed view of craftsmanship. Widely accepted in the global market, IGI certificates provide both reliability and diverse options for consumers.
Diamond color grading ranges from D to Z, with D-F being colorless, and D being the most rare and pure. G-J are near-colorless, with faint undertones that still maintain brilliance in specific lighting. As the grade decreases, the color deepens, transitioning from light yellow to the noticeable yellow of Z. RAGAZZA exclusively selects the highest-grade D color diamonds, renowned for their flawless whiteness, which sparkle with exceptional brilliance in any light, perfectly embodying their rare and incomparable value.
Diamond clarity ranges from IF+ (internally flawless) to I (included), reflecting the presence of internal and surface imperfections. RAGAZZA’s IF+ diamonds are exceptionally rare, offering flawless brilliance. VVS and VS grades feature only minute inclusions, barely visible even under magnification. While SI and I grades may show visible inclusions, a well-balanced choice across the 4Cs ensures optimal beauty and value.

Diamond Certification and Grading Explained
Cut is the key to a diamond’s brilliance - precise angles allow light to reflect and refract perfectly, creating exceptional sparkle. Graded from Excellent to Poor, only Excellent cuts fully maximize brightness. In contrast, deep or shallow cuts cause light leakage, diminishing radiance. RAGAZZA selects diamonds with Good to Excellent+ cuts, ensuring optimal light performance and unmatched brilliance.
