The 4 Cs of Certified Loose Diamonds

Cut: The Key to Brilliance

And the way a diamond is cut dictates its brilliance and fire. Light travels through and bounces back, creating a brilliant sparkle. The cut is graded on a scale ranging from Excellent to Poor, with brilliant cut diamonds having the most brilliance.

• Round Brilliant Cut: The most common and sparkliest diamond shape.

• Princess Cut: A contemporary square-shaped cut.

• Cushion Cut: A soft square or rectangular vintage-inspired cut.

• Emerald Cut: A sleek, step-cut diamond that has less sparkle but more clarity.

Color: The Absence of Hue

Diamonds are graded for color on a scale from D (colorless) to Z (light yellow or brown). The less color in a diamond, the more it is worth.

• D-F (Colorless): Very rare and valuable.

• G-J (Near Colorless): the great compromise between value and looks.

• K-M (Faint Yellow): Slightly warm in tone, less expensive.

• N-Z (Noticeable Yellow/Brown Tint): Less desirable for $ but affordable.

GETTING CLARITY: Reviews of Inclusions & Blemishes

Clarity describes internal inclusions and external blemishes. Diamonds range from Flawless (FL) to Included (I1, I2, I3):

• FL-IF (Flawless, Internally Flawless): Very Rare Expensive

• VVS1-VVS2 (Very Very Slightly Included): Minor inclusions not detectable.

• VS1-VS2 (Very Slightly Included): Very small inclusions, only visible with a magnifying glass.

• SI1-SI2 (Slightly Included): Inclusions visible only under magnification but the best value.

• I1-I3 (Included): Noticeable inclusions can affect durability and brilliance.

Carat Weight: Size and Perceived Value

Carat weight reflects a diamond’s size. Carat weight affects size but a better cut delivers more perceived size and brilliance than carat weight alone.

• 0.50-1.00 Carat: Classic and elegant.

• 1.00-2.00 Carat: Common for engagement rings.

• 2.00+ Carats: The ultimate luxury statement piece.
