The 4Cs of Diamonds: Your Guide to Quality

The 4Cs—Cut, Color, Clarity, and Carat Weight—are the global standard for evaluating diamond quality. Each factor influences a diamond’s appearance, value, and brilliance.

1. Diamond Cut: The Key to Sparkle

The Cut is the most critical factor, determining a diamond’s brilliance (light reflection), fire (color dispersion), and scintillation (sparkle). A well-cut diamond maximizes light performance, creating a mesmerizing glow.

• Cut Grades: Graded by labs like GIA and IGI as Excellent, Very Good, Good, Fair, or Poor. Riona Jewel prioritizes Excellent and Very Good cuts for maximum sparkle.

Diamond Shapes (distinct from cut):

• Round Brilliant: The most popular, offering unparalleled brilliance.
• Princess: Modern square shape with vibrant fire.
• Oval: Elegant and elongating, ideal for slender fingers.
• Emerald: Sophisticated rectangular step-cut with a hall-of-mirrors effect.
• Pear: Teardrop shape blending round and marquise elegance.
• Cushion: Romantic square or rectangular with rounded corners.
• Asscher: Unique square step-cut with cropped corners.
• Radiant: Brilliant facet patterns in a square or rectangular shape.
• Marquise: Boat-shaped, appearing larger than its carat weight.

Pro Tip: Choose an Excellent or Very Good cut for lab grown diamonds to ensure stunning sparkle in any shape.

2. Diamond Color: The Beauty of Clarity

Color refers to the absence of tint in a diamond. The less color, the higher the grade and value. Diamonds are graded from D (colorless) to Z (light yellow/brown).

• D-F (Colorless): Rare and completely clear, ideal for white gold or platinum settings.
• G-J (Near-Colorless): Appear colorless to the untrained eye, offering excellent value.
• K-M (Faint Color): Slight tint, best paired with yellow gold to mask color.

Riona Jewel offers lab grown diamonds in the D-J range, ensuring vibrant sparkle with no noticeable tint, especially in 10K, 14K, or 18K solid gold settings.

3. Diamond Clarity: Purity in Focus

Clarity measures the presence of inclusions (internal flaws) and blemishes (external flaws). Most are microscopic and invisible to the naked eye. Clarity grades range from Flawless (FL) to Included (I).

• FL/IF (Flawless/Internally Flawless): No inclusions or blemishes under 10x magnification. Extremely rare.
• VVS1/VVS2 (Very, Very Slightly Included): Inclusions barely visible under 10x magnification.
• VS1/VS2 (Very Slightly Included): Minor inclusions, often eye-clean, offering great value.
• SI1/SI2 (Slightly Included): Inclusions may be visible under 10x magnification but often eye-clean.
• I1-I3 (Included): Visible inclusions that may affect transparency or brilliance.

Riona Jewel focuses on VS2 to SI1/SI2 clarity grades, providing eye-clean lab grown diamonds that maximize beauty and affordability.

4. Diamond Carat Weight: Size Meets Value

Carat Weight measures a diamond’s weight (1 carat = 200 milligrams). While carat affects size, cut and shape influence perceived size.

• Larger carat weights are rarer and more valuable.
• Shapes like Oval or Marquise may appear larger than a Round Brilliant of the same weight.
• Total Carat Weight (TCW) applies to pieces with multiple diamonds, like bracelets or pavé rings.

With lab grown diamonds, Riona Jewel helps you achieve significant carat weights within your budget, creating show-stopping jewelry.
