Color: The absolute finest colorless stone carries a D rating, descending through each letter of the alphabet to Z. We at Bonicci recommend selecting a diamond with a color grade of H or better. Cut: The cut of a diamond refers to its proportion. Bonicci's Super ideal Cut diamond with the Hearts & Arrows effect generates an average 99% light return. GIA laboratory certifies Bonicci's diamonds as Triple Excellent (Polish, Symmetry and Cut). AGS laboratory certifies Bonicci's diamonds as Triple-0 (Light Performance, Proportion and Finish). Clarity: Almost all diamonds contain very tiny natural birthmarks known as inclusions. To determine a diamond's clarity, an expert views it under 10X power magnification. We at Bonicci recommend selecting a diamond with a clarity grade of VS2 or better. Carat: The rarity of a diamond is greatly affected by its size. However, carat weight alone does not determine a diamond’s value. Two stones of equal weight can vary widely in price because of quality differences. In fact, a smaller diamond may actually be more beautiful than a larger stone with inferior cut, clarity, color or presence. We at Bonicci recommend selecting diamonds greater than 0.30 carats. |
