Diamond Clarity and Inclusions Guide: What Actually Matters

Diamond Clarity Guide: Eye Clean Value
Use the actual diamond, not the clarity label, as the final decision.
By Josh Allen, Co-Founder of YourDiamondGuys.com. Fifth generation diamantaire with 30 plus years in the global diamond trade. Former supplier to Tiffany & Co., Cartier, and Harry Winston.
Diamond clarity only matters when the inclusion changes beauty, durability, price, or confidence. A clean looking SI1 can be a better buy than a higher clarity stone with a dark mark under the table. A paper grade starts the search. The actual diamond finishes it.
For natural diamonds, start with GIA. Then use video, the clarity plot, normal viewing distance, and inclusion type to decide whether the tradeoff is smart or just discounted trouble.
The central entity here is diamond clarity. The real buyer intent is simple: find the lowest safe clarity that still looks clean, holds up in the setting, and leaves more budget for the parts of the diamond you actually see.
What This Clarity Hub Covers
This page is the parent guide for diamond clarity. It connects eye clean standards, GIA clarity grades, inclusion type, inclusion location, shape visibility, durability risk, clarity plots, videos, setting strategy, and budget tradeoffs into one buying decision.
Eye clean reality
How a diamond looks from normal distance, in real lighting, and in motion.
Inclusion identity
Crystals, feathers, clouds, needles, twinning wisps, graining, knots, chips, cavities, and naturals.
Location and shape
Why table, girdle, pavilion, prong position, and diamond shape change what buyers notice.
Value and risk
When to save money on clarity, when to spend on cut or carat, and when to skip the stone.
Trade Insider Moment: Inside the trade, nobody stops at VS2, SI1, or I1. We ask what set the grade, where it sits, whether it reaches the surface, whether the video keeps pulling the eye there, and whether the price actually pays you for taking the tradeoff. Same grade. Different diamond. Different decision.
The Diamond Clarity Map
This is the order I like for buyers. Start with what the naked eye sees, then work toward the report details that change safety, price, and setting decisions.
| Cluster Area | Buyer Question | Best Starting Guides |
|---|---|---|
| Clarity foundation | What does clarity actually change in a buying decision? | Diamond Clarity and Inclusions Guide, Eye Clean Diamonds |
| Visibility checks | Will I see the inclusion without magnification? | Black vs White Inclusions, Busy Inclusions, Clouds and Haze |
| Report and video proof | How do I connect the GIA plot to the actual diamond? | Read a Clarity Plot, Inclusion Location |
| Durability risk | Which inclusions can become setting or wear problems? | Feathers, Knots, Cavities and Chips |
| Budget tradeoffs | Where should clarity give way to cut, size, or setting strategy? | Clarity vs Cut, Clarity vs Carat, Prong Hide Strategy |
Quick Diamond Clarity Orientation
Use these terms as a buyer screen, not as a lab exam. The name of the inclusion matters less than what it does in the actual diamond.
| Term | What It Means For Buyers | What To Do Next |
|---|---|---|
| Eye clean | The inclusion does not show to your naked eye from normal viewing distance. | Check video slowly, then confirm the mark does not create durability risk. |
| Table inclusion | A mark under the top center of the diamond usually gets noticed faster. | Be stricter with dark crystals, busy clusters, or anything your eye keeps finding. |
| Girdle inclusion | An edge mark can hide better, but it can also affect setting safety. | Review feathers, chips, cavities, naturals, and indented naturals before setting. |
| Cloud or graining | The issue is not always a single mark. Sometimes the whole stone looks sleepy. | Reject haze, milkiness, or transparency loss even when the report sounds clean. |
| Clarity enhancement | Laser drilling or fracture filling changes value, durability, and disclosure risk. | Treat enhancement as a separate buying category, not a normal clarity discount. |
What This Hub Does Not Try To Do
This hub does not tell you to buy the highest clarity grade you can afford. That is how buyers waste budget. It also does not excuse every lower clarity diamond. The point is to separate smart eye clean value from visible, risky, or poorly disclosed clarity problems.
Use These Guides In This Order
Do not read these like homework. Use them like a buying route. Start with eye clean value, then move into the specific inclusion risks that can make the grade lie.

The Real Clarity Test
A diamond passes clarity when the beauty, durability, setting plan, report, video, and price all make sense together.
That sounds simple. It is not how most listings are sold. Sellers like the one label that makes the stone look clean. VS2. SI1. Eye clean. Loupe clean. Pick the wrong label and you can miss the real issue.
Use this sequence before you buy
- For natural diamonds, start with GIA.
- Check whether the diamond looks clean from 8 to 12 inches.
- Find the grade setting inclusion on the clarity plot.
- Watch the actual video slowly, not a sample video.
- Check whether the inclusion sits under the table, near the girdle, or near a prong.
- Reject risky issues like bruise, chip, cavity, knot, etched channel, or indented natural when the price does not pay you for the risk.
- Compare the clarity tradeoff against cut, size, setting, and total price.
Mistakes That Make Clarity Look Safer Than It Is
- Judging clarity from the grade alone instead of the actual diamond.
- Ignoring black crystals under the table because the report says VS2 or SI1.
- Treating a surface reaching feather, knot, cavity, chip, etched channel, or indented natural like a harmless internal mark.
- Accepting haze, milkiness, or a sleepy center because the inclusion list sounds minor.
- Letting prong strategy hide a real durability issue instead of solving it.
A Simple Buyer Example
Say two round diamonds both look good on paper. One is VS2 with a dark crystal under the table. The other is SI1 with a pale edge feather that does not reach the surface and disappears in normal viewing. I would study the SI1 harder. The grade is not the prize. The actual diamond is.

Questions To Ask Before You Buy
- What inclusion sets the clarity grade?
- Where is the inclusion on the GIA plot?
- Can I see the actual diamond video, not a sample video?
- Is the mark visible from 8 to 12 inches in normal light?
- Does the inclusion reach the surface, sit near the girdle, or affect setting safety?
- Is the price adjusted for the real clarity tradeoff?
Where I Would Compare Clarity Videos
Use these sites as comparison tools, not automatic recommendations. I would compare similar GIA natural diamonds on Ritani and Blue Nile, then use the guides here to judge the plot, video, inclusion location, shape visibility, return terms, and price before trusting the clarity grade.

Questions Buyers Ask Us
Start with the main clarity guide. Then read eye clean diamonds before you compare feather, crystal, cloud, knot, or other inclusion pages.
You want the lowest clarity that still looks clean, stays safe in the setting, and is priced fairly for the actual stone.
Surface reaching feathers, knots, cavities, chips, etched channels, indented naturals, hazy clouds, and clarity enhancement need the strictest review.
No. A clean looking SI1 with a safe edge inclusion can beat a VS2 with a dark mark under the table. The grade helps you sort. The actual diamond makes the decision.
Yes. For natural diamonds, start with GIA. It gives you a stricter baseline before the video, plot, inclusion location, and price get the final vote.
