Diamond Cut Grades: How A Diamond Is Cut Affects It's Brilliance

The way a diamond is cut has the biggest impact on how it looks in real life—its sparkle, brightness, and overall personality. Here’s how each cut grade plays into your custom engagement ring, custom pendant, or custom earrings design.

Look
On the Hand
Best For
Excellent (EX)
Excellent Cut
Top Performance • Maximum Sparkle

Exceptional brilliance and fire with even, bright light return from every angle.

Clean, crisp sparkle that looks lively in all lighting—perfect for center stones.

Clients who want the most radiant look and prioritize cut quality.

Very Good (VG)
Very Good Cut
Bright & Beautiful • Near-Top Sparkle

Strong brilliance and fire with only minor differences from Excellent to the naked eye.

Beautiful, lively sparkle that performs very well in everyday lighting.

Custom pieces where you want a balance of high performance and budget flexibility.

Good (GD)
Good Cut
Pretty Sparkle • Thoughtful Value

Noticeable sparkle with some areas of darkness or reduced light return.

Still attractive, especially in smaller stones or designs with multiple diamonds.

Accent stones, pavé, or clients who prefer to prioritize size over top-tier cut.

Fair (F)
Fair Cut
Subtle Sparkle • Compromised Light

Limited brilliance; the diamond can appear slightly dull or flat.

Less “wow” factor, especially in larger sizes or center stones.

Only specific design situations where cut is less visible and budget is primary.

Poor (P)
Poor Cut
Low Sparkle • Noticeable Light Loss

Dull appearance with obvious dark areas and minimal fire.

Often looks smaller and less lively than its carat weight suggests.

Custom Jewelry Online vs. a Local Jeweler: What's Actually Different — new article. Covered in the article: the three setups sold as "custom," why gram weight changes a quote more than most buyers realize, what a properly itemized quote lists, how virtual stone inventory compares to a local case, typical three-to-five-week timelines, and the cases where a local jeweler is the better choice — sizing, hand engraving, antique restoration, and short deadlines. https://thecustomjeweler.com/custom-jewelry-articles
