天然開採而來的鑽石，每粒都獨一無二，珍稀罕有。是愛和永恆的象徵之物。
F級鑽石帶些微顏色，只有專業的寶石學家能分辨。雖然F級鑽石比D、E級較具顏色，但它仍屬於無色級別。
放大10倍後可辨視得到，但肉眼不易看見。
在極佳的切工下，鑽石能從火彩及光澤兩者間取得出色的平衡。世上只有3%鑽石的切工能被評為優異。

EXCELLENT
Unique and rare gems symbolizing love and eternity, mined from nature.
F grade diamonds have slight color which can only be detected by a professional gemologist. Although F diamonds have slightly more color than D and E diamonds, they are still under colorless grade.
Slightly included. The inclusions are detectable under 10x magnification, but are not very visible to the naked eye.
Superior quality cut that produces a striking balance of fire and brilliance. Only 3% of the world’s diamonds are graded as excellent.
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.
