    Seal of Authority - Diamond Certification and Grading Explained

    cert giaiai.jpg

    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.

    cert cut.jpg

    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
    Natural diamonds showcase natural beauty and rarity, while lab grown diamonds offer affordability and functionality.

    • What is the difference between platinum, 18K gold and 925 silver?"
      18K white gold (AU750) 18K white gold is made up of 75% precious metal "gold" plus 25% other white metals, making it a silver-white combination. It is a common material for high-end jewelry. 18K gold is characterized by its strength and durability, and is suitable for long-term wear. We recommend customers to choose 18K gold. Platinum (PT950) PT950 is composed of 95% precious metal "Platinum" plus 5% other hard metals. The natural silver white color is extremely durable and will not oxidize, making it the most ideal high-grade material. Platinum is heavy and hard. It is suitable for long-term wear. If you perfer PT950 for your jewelry, please contact us. Sterling Silver (S925) S925 sterling silver is a more common silver-white precious metal. Because it is not very hard and can oxidize easily, other white metals is plated on the surface of pure silver to make it harder to oxidize. However, frequent cleaning is still needed to maintain its shine.
