Understand the diamond. Choose with confidence.
Discover the 4Cs, explore shapes, and learn how lab-grown and mined diamonds compare. We help you find the balance of beauty, origin, and budget that suits you.
Both are diamonds. Compare their origins, appearance, pricing, and reports.
Cut, color, clarity, and carat describe different aspects of a diamond. Consider them together, then look closely at the individual stone.
01 / Light
Cut quality describes how a diamond’s proportions and craftsmanship interact with light. Shape describes its outline. A well-cut stone balances brightness, flashes of color, and sparkle.
GIA’s standard round brilliant cut grades run from Excellent to Poor. Fancy shapes require their own visual and proportion review; one set of angles does not suit every shape.

02 / Tone
For diamonds in the normal color range, the D–Z scale measures the presence of color. Small grade differences can be subtle. Fancy-color diamonds are evaluated differently.
Consider the actual stone alongside your preferred metal. A grading report describes color under controlled conditions; your ring will be seen in everyday light.

03 / Characteristics
Clarity considers internal inclusions and surface blemishes. The GIA scale has 11 grades, assessed under 10× magnification.
“Eye-clean” is a visual description, not a laboratory grade. Inclusion position, size, and visibility matter; a grade alone does not guarantee an eye-clean appearance.

04 / Weight
Carat measures weight, not face-up size. Diamonds with the same carat weight can have different visible dimensions because of their shape and proportions.
Compare measurements in millimeters as well as carats. For a setting, the diamond’s exact dimensions and shape are part of confirming fit.

The outline sets the character of a ring. These illustrations show silhouettes, not relative carat sizes.
Confirm natural or laboratory-grown origin, shape, measurements, carat weight, and disclosed treatments. Grading systems can differ by laboratory and report date. Verify the report with the issuing laboratory and review the individual diamond’s images or video. Compare lab-grown report formats.
Fluorescence is a diamond’s response to ultraviolet light. It is separate from the 4Cs. Review the individual stone’s appearance rather than treating fluorescence alone as a verdict on beauty.
Both mined and lab-grown diamonds resist scratching but can chip from a hard impact. Clean gently with mild soap, warm water, and a soft brush when suitable for the complete piece. Have the setting inspected regularly, and ask before using ultrasonic or steam cleaning, particularly for treated stones or rings with other gems. GIA: diamond care.
