Seal of Authority - Diamond Certification and Grading Explained

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.

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.

Natural Diamond VS Lab Grown

18K Gold (AU750): 18K white gold is composed of 75% precious metal "yellow gold" and 25% other white metals, giving it a silvery white color. 18K gold is characterized by its high hardness, providing enhanced protection for gemstones, and is extremely durable, making it suitable for long-term wear. We recommend 18K gold for your permanent jewelry.

Platinum (PT950) is composed of 95% precious metal platinum and 5% other hard metals. Its natural silvery white color is highly durable and resists oxidation, making it an ideal premium material. Platinum is also heavy and durable, making it suitable for long-term wear. We also recommend PT950 platinum for permanent jewelry.

Pure Silver (S925): S925 pure silver is a common silvery-white precious metal. Due to its low hardness and easy oxidation, we plate it with 18K white gold, giving it the same appearance as 18K white gold. However, it requires frequent cleaning over time to maintain its luster. We recommend S925 for occasional wear.
