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.
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 of exceptional cut quality, ensuring optimal light performance and unmatched brilliance.
