Diamond Buying Guide
In this guide, we share clear and friendly advice to help you confidently select a diamond that reflects your personality and meets your expectations.
Understand the 4Cs of Diamonds
The 4Cs—Cut, Color, Clarity, and Carat—are key to understanding diamond quality:
Color: Finding Your Shade
Diamonds are graded on a color scale that follows the alphabet from D to Z. Grade D diamonds are completely colorless and highly prized. As you move down the scale toward Z, diamonds show increasing visible tint. Colorless diamonds fall within grades D to F, while near-colorless diamonds are graded G to H and often offer excellent value without obvious tint.
Clarity: Embracing Imperfections
Almost all diamonds have natural inclusions. Clarity grades measure how visible these inclusions are. Selecting a diamond graded VS1 to SI1 typically means imperfections aren’t visible to the naked eye but offer great value.
Cut: Bringing Out the Sparkle
The cut of a diamond determines how brilliantly it reflects light. A well-cut diamond catches the eye and dazzles with sparkle and fire. Aim for an "Excellent" or "Very Good" cut to ensure maximum brilliance.
Carat: Size and Value
Carat weight indicates a diamond’s size. Keep in mind that diamonds slightly below popular carat weights (like 0.95 ct instead of 1 ct) can provide significant savings without a noticeable difference in appearance.
Choose a Diamond Shape That Fits You
Diamond shapes express your individual style. Visualize how each shape complements your hand or browse inspiration photos to discover your perfect match.
Diamond Fluorescence: Hidden Value in the Glow
Diamond fluorescence is a gentle glow some diamonds emit under ultraviolet (UV) rays, usually appearing blue. Around a third of diamonds exhibit some fluorescence, but noticeable intensity is less common. Bluish fluorescence can enhance lower color grades (I–M), making faintly yellow diamonds appear whiter in daylight, sometimes increasing their value. In higher grades (D–H), strong fluorescence may lower the price due to perceived haziness, although actual clarity impact is rare, providing opportunities for excellent value.
Importance of Certification
Always select diamonds certified by reputable labs such as GIA, IGI, or HRD. Certification ensures authenticity, quality, and peace of mind. Additionally, check the laser inscription on the diamond’s girdle to verify its certification number, which confirms the diamond matches the report and guarantees its traceability.
The Rapaport Price List: Diamond Pricing Guide
The Rapaport Price List is the diamond industry's primary reference for pricing diamonds. It provides suggested prices—not actual selling prices—based on what Rapaport believes dealers typically ask for diamonds that meet certain quality standards. Jewelers and traders worldwide use this guide as a starting point to negotiate and determine fair market prices.
