How to Identify a Well-Cut Diamond

How to Identify a Well-Cut Diamond

Diamonds are like people—some shine brighter than others. And the secret to that show-stopping sparkle? It’s not size, clarity, or even the price tag—it’s the cut.

You could have a massive diamond, but if it’s not cut right, it won’t shine—it’ll just sit there looking awkward. So, how do you spot a well-cut diamond? How do you know if your gem is dripping in brilliance or just taking up space? Let’s break it down.

Lab Grown Diamond

Why Diamond Cut is a Big Deal

When we talk about a diamond’s cut, we’re not talking about its shape (round, oval, princess, etc.). The cut determines how well the diamond interacts with light, affecting its:

  • Brilliance – The amount of white light reflected.

  • Fire – How light disperses into rainbow colors.

  • Scintillation – The sparkle effect when the diamond moves.

Think of it like this: a bad cut lets light escape, making the diamond look dull and lifeless. A perfect cut traps the light inside and reflects it back—that’s where the magic happens.

The 3 Main Types of Diamond Cuts

Types of Diamond Cuts

Not all cuts are created equal. Diamonds are generally classified into three major cut styles, each offering a different look and level of brilliance.

Cut Type

Key Features

Example Shapes

Best For

Brilliant Cut

Triangular facets, max sparkle, masks imperfections

Round, Princess, Cushion, Oval

People who love high shine & timeless styles

Step Cut

Rectangular facets, mirrors effect, elegant look

Emerald, Asscher, Baguette

Fans of sleek, modern, sophisticated diamonds

Mixed Cut

Combines brilliant & step cut features, unique look

Radiant

Those who want a balance of fire & clarity

Each cut has its own personality—so pick one that fits yours!

How to Spot a Well-Cut Diamond (Like a Pro)

Now that you know the basics, let’s talk about red flags and green flags when choosing a diamond.

1. The “Too Deep, Too Shallow” Test

Diamonds need perfect proportions to reflect light properly.

  • Too Deep – Light leaks out the bottom → Dull, lifeless diamond

  • Too Shallow – Light escapes from the sides → Low sparkle, poor brilliance

  • Just Right – Light bounces perfectly inside → Blinding brilliance

Tip: Hold the diamond under a light and see how evenly it sparkles. If there are dull spots, it’s not an ideal cut.

2. Symmetry & Facets – The Light Show Effect

Facets are like tiny mirrors inside a diamond, reflecting and refracting light. Perfect symmetry = better light performance.

Well-cut diamonds have uniform, precise facets.

Uneven facets create dark zones (“dead spots”) that kill the sparkle.

Tip: Look for diamonds with a GIA cut grade of Excellent or Very Good—anything lower could have symmetry issues.

3. The “Mirror Shine” Polish Test

A highly polished diamond has a glass-like shine that enhances its brilliance. If the polish isn’t good, light will scatter instead of reflecting properly.

Smooth, mirror-like polish = high brilliance

Rough, scratched surfaces = dull appearance

Tip: Inspect the diamond under a 10x magnification loupe—a top-tier polish will be free from any surface marks.

4. The Sparkle Test – The Ultimate Check

This one’s easy—just move the diamond under different lighting conditions:

  • Sunlight – Does it throw out rainbow colors (fire)?

  • Soft indoor lighting – Does it glow beautifully?

  • Dim settings – Does it still shimmer?

A well-cut diamond will sparkle in every light—if it looks dull in some settings, it’s probably not the best cut.

Diamond Cut Grades – What You Should Look For

Diamond Cut Grades

If you want the best sparkle, don’t settle for anything less than this:

Cut Grade

What It Means

Should You Buy It?

Excellent

Maximum brilliance, perfect proportions

Best choice!

Very Good

High brilliance, minor differences from Excellent

Still a great pick

Good

Decent sparkle, but less light return

Only if you're on a budget

Fair/Poor

Light leakage, reduced brilliance

Hard pass

Always aim for Excellent or Very Good if you want top-tier sparkle.

Lab-Grown Diamonds & Cut Perfection

Here’s something most people don’t realize—lab-grown diamonds have an edge when it comes to cut quality.

  • More Precision – Since they’re grown in a lab, they can be cut with laser accuracy.

  • Better Clarity – No weird inclusions to block light.

  • Sustainable & Ethical – All the luxury, none of the guilt.

At Ivana Jewels, we handpick and craft every lab-grown diamond to optimize cut quality, so you always get flawless brilliance.

What’s the Best Cut for Maximum Sparkle?

If you want serious brilliance, here’s your go-to guide:

  • For insane sparkle → 57-facet round brilliant cut (Excellent grade)

  • For a refined, mirror-like glow → Emerald or Asscher cut

  • For a soft, glowing shimmer → Cushion or oval cut

And remember—size means nothing if the cut isn’t right. A smaller well-cut diamond will outshine a larger poorly-cut one every single time.
