Crystal Grades Explained: What Do A, AA, AAA and X Grade Really Mean?
Hi Sunflowers,
Have you ever looked at a crystal labelled A Grade, AA, AAA or X Grade and wondered:
Who decided that?
We certainly have.
If you've ever browsed crystals from different suppliers, you may have noticed that some are described using letter grades such as A, AA or AAA, while others might be called Premium, Extra Quality or X Grade.
But here's the important part:
There isn't one universal crystal grading system.
Unlike some gemstones that are assessed using established gemological standards, labels such as A, AA and AAA can be quality descriptions created and used by individual companies. GIA specifically notes that there is no standard quality-grading scale for amethyst, despite these labels being commonly used in the trade.
So what does a crystal's grade actually tell us?
Let's take a closer look.
What Does "Crystal Grade" Mean?
When a supplier assigns a grade to a crystal, they are generally trying to communicate something about the quality or appearance of the material.
Depending on the crystal and the supplier's own grading system, this might involve looking at things such as:
Colour and colour intensity
Clarity
Natural inclusions
Patterns and markings
Surface quality
Polish
Shape and symmetry
Chips, cracks or other damage
Overall visual appearance
The characteristics that matter can also vary considerably depending on the type of crystal.
For example, GIA identifies colour, clarity, cut and carat weight as important factors when assessing the value of amethyst. Strong, attractive colour and good clarity can increase its desirability, although visible inclusions do not automatically make a piece unattractive or without value.
This is where things get interesting.
A grade can tell you something about a crystal, but it can't tell you whether you're going to love it.
Are A, AA and AAA Official Crystal Grades?
No.
This is probably the most important thing to understand when shopping for crystals.
There is no universal industry-wide system where every crystal seller uses exactly the same criteria for A, AA, AAA or X Grade.
One supplier might use AAA to describe material with excellent colour and clarity, while another supplier could use the same term according to a slightly different set of criteria.
GIA specifically explains that companies can create their own descriptions such as A, AA and AAA to indicate ranges of quality, but these are not standardised grading scales for amethyst.
The same principle applies when you encounter terms such as:
Premium Grade
Extra Quality
Collector Grade
X Grade
AAAA
Super Grade
These names can be useful as supplier descriptions, but they shouldn't automatically be treated as internationally recognised grades.
So if you see an X Grade crystal, it doesn't mean there is a universal organisation somewhere that has officially declared:
"This crystal has achieved X Grade status."
Wouldn't that be a fun job, though?
So What Does X Grade Mean?
This is one of the questions that started this whole article for us.
X Grade is not a universal gemological grading standard.
If a supplier describes a crystal as X Grade, it is their own classification for a particular level of quality.
The supplier may be using the term to indicate things such as:
Exceptional clarity
Strong colour
Minimal visible imperfections
Excellent polish
Attractive shape
Particularly desirable material
However, the exact criteria depend on the supplier.
This is why it's important not to assume that an X Grade crystal from one supplier will necessarily meet the exact same criteria as an X Grade crystal from another.
What Makes a Crystal Higher Grade?
There isn't one checklist that applies perfectly to every crystal, but there are some characteristics that commonly influence how material is assessed.
Colour
For many coloured crystals and gemstones, colour is an important consideration.
With amethyst, for example, GIA identifies strong reddish-purple to purple colouring as particularly desirable, provided the colour isn't so dark that the stone loses brightness. Colour zoning can also affect value.
But even here, personal preference comes into play.
One person might adore pale lavender amethyst, while another is searching for the deepest purple they can find.
Clarity
Clarity generally refers to how transparent or visually clear a crystal or gemstone is and how many inclusions can be seen.
In faceted amethyst, eye-clean material is generally more valuable when other qualities are comparable. However, GIA also notes that amethyst with visible inclusions can still have attractive colour and may be fashioned into cabochons or beads.
And this brings us to one of our favourite things about crystals...
Are Inclusions Bad?
Not necessarily.
Inclusions are natural features within a crystal. Depending on the material, they can include other minerals, internal fractures, clouds, veils, growth features and other fascinating structures.
From a commercial perspective, certain inclusions may reduce the value of a particular type of gemstone.
But from a crystal lover's perspective?
Sometimes they're the best bit.
We absolutely love finding crystals with unusual inclusions, interesting patterns and little features that make us stop and look twice.
A crystal doesn't have to be perfectly clear to be fascinating.
In fact, sometimes the things that make a crystal less commercially desirable are exactly what make it interesting to look at.
Can Lower-Grade Crystals Have Rainbows?
Absolutely.
A rainbow isn't a certificate of quality.
Natural quartz can display iridescence through optical effects involving very fine structures and thin-film interference. GIA research has documented natural iridescent quartz, also known as iris quartz or rainbow quartz, and has examined the microscopic structures responsible for its colours.
Iridescence can also occur in mineral fractures because thin-film effects can interfere with reflected light.
That means a crystal with visible internal features or fractures can sometimes contain a spectacular rainbow.
And that's rather wonderful.
Something that might be considered an imperfection from one perspective can be responsible for one of the most beautiful things you'll see inside a crystal.
It also means that:
A high-grade crystal can have a rainbow.
A lower-grade crystal can have a rainbow.
A rainbow does not determine the grade.
And not every colourful or iridescent-looking quartz is naturally formed in the same way. Some quartz has been treated or coated to create an iridescent appearance, so it's important not to assume that every rainbow effect has the same origin.
Does a Higher Grade Mean a Better Crystal?
This is where we think the answer gets a little more interesting.
A higher grade can indicate that a crystal has certain qualities that are considered desirable.
But "higher grade" doesn't necessarily mean more beautiful.
Beauty is subjective.
You might hold a crystal that is exceptionally clear and polished and think:
"Wow."
Then you might pick up another crystal covered in inclusions and unusual markings and have exactly the same reaction.
We do.
Some of our favourite crystals are the ones where you can spend ages looking into them and discovering something new.
And then, every now and again, we find an exceptionally high-grade specimen and get ridiculously excited about that too.
There's room for both.
Why Do Some Sunflower Hollows Crystals Have Grades?
This is where we want to be completely transparent about how we source our crystals.
Some of our crystals are supplied to us with a quality grade from our wholesalers.
When you see a grade such as A, AA, AAA or X Grade on one of our products, that grade comes from our supplier.
It isn't a grading system that we have created ourselves, and we don't claim that it represents a universal industry standard.
We pass the supplier's information on to you because we think it's useful information when deciding whether a particular crystal is right for you.
Where a supplier doesn't provide a grade, we don't invent one.
We'd much rather tell you that a crystal is not graded than create a fancy-sounding grade simply to make it sound more impressive.
But We Personally Handpick Every Crystal
There's another important part of our sourcing process that a product label can't tell you.
We handpick our crystals ourselves.
One of our favourite parts of running Sunflower Hollows is visiting our suppliers' warehouses and choosing the crystals we want to bring home.
We don't simply place an order for a certain number of crystals and have a warehouse randomly select them for us.
We physically look through what's available and choose the pieces ourselves.
Sometimes we're looking for something specific.
Sometimes a particular colour catches our eye.
Sometimes we find an unusual inclusion or pattern.
Sometimes we pick up a crystal and immediately think:
"Yep. You're coming home with me."
And sometimes we find an exceptionally clear, high-grade specimen and get ridiculously excited about it.
The supplier's grade is one piece of information.
The actual crystal in front of us is what makes the final decision.
Why We Don't Only Buy the Highest Grades
If we only bought the highest-graded crystals we could find, our collection would be missing some of the things we love most about crystals.
We love the weird ones.
The cloudy ones.
The ones with fascinating inclusions.
The ones with unusual patterns.
The ones that aren't perfectly symmetrical.
The ones where you turn them around and suddenly discover something completely different on the other side.
And we also love the exceptional ones.
The crystal-clear spheres.
The incredibly saturated colours.
The beautifully polished pieces.
The specimens that make you stop in the warehouse and stare at them for a moment.
We don't think one kind of beauty cancels out the other.
Crystals for Different Budgets
We also believe crystals should be accessible to people with different budgets.
Not everyone can spend hundreds of dollars on a crystal, and we don't think they should have to.
When we're choosing stock, we look for beautiful pieces across a range of price points so that someone can find something special whether they're spending a few dollars or saving for a more exceptional specimen.
That's another reason we don't simply chase the highest grades.
A fascinating crystal with plenty of natural inclusions can be an affordable and wonderful addition to someone's collection, while a particularly rare or exceptional specimen might command a much higher price.
Both can be worth bringing home.
What matters is finding the crystal that speaks to you.
Crystal Grades and the Beauty of Imperfection
Perhaps this is where crystals have something to teach us.
We can sometimes become very focused on the things that aren't perfectly clear, smooth, symmetrical or uniform.
But look closely at a crystal.
The inclusions.
The fractures.
The colour variations.
The little imperfections.
The unusual patterns.
They're part of its story.
And perhaps we're a little like that too.
None of us comes without quirks, imperfections or things we'd change about ourselves. But those differences are part of what makes each person uniquely themselves.
A crystal doesn't have to be commercially "high grade" to be extraordinary.
Sometimes the very feature that affects its grade is the feature that makes you stop and stare.
How Should You Choose a Crystal?
If you're shopping for crystals, we'd recommend using grades as one piece of information rather than the whole decision.
Consider:
Do you love the colour?
Do you like the natural inclusions or patterns?
Does the shape appeal to you?
Is the quality appropriate for what you want to use it for?
Does the price fit your budget?
Are you drawn to the individual piece?
And perhaps most importantly:
Do you actually like it?
Because there's not much point buying a supposedly "higher grade" crystal if you don't love looking at it.
Frequently Asked Questions
Is AAA crystal better than AA?
Not necessarily in every sense. A, AA and AAA are supplier-created quality descriptions rather than universal grading standards, so the exact meaning can vary between sellers. GIA specifically confirms that no standard quality-grading scale exists for amethyst.
Is X Grade higher than AAA?
There is no universal answer. X Grade is not a standardised gemological grade, so its meaning depends on the supplier using the term.
Can a lower-grade crystal have beautiful inclusions?
Absolutely. Inclusions can create fascinating patterns and visual features, and their presence doesn't automatically make a crystal unattractive.
Can high-grade crystals have inclusions?
Yes. The amount and type of inclusions that are considered desirable or undesirable depend on the material and how it is being evaluated.
Can any grade of quartz have a rainbow?
Natural iridescence can occur in different quartz specimens and isn't itself an indicator of grade. Some rainbow effects are associated with internal structures or fractures, while natural iris quartz can display iridescence through other microscopic structures.
Why doesn't Sunflower Hollows grade its own crystals?
Because we don't want to invent a grading system and present it as an industry standard. Where a supplier provides a grade, we pass that information on as supplier-provided information. Our own role is to personally select the individual crystals we want to bring into the shop.
Does a high-grade crystal cost more?
It can, but not always. Price depends on many factors, including the type of crystal, size, colour, rarity, quality, workmanship and market demand.
Final Thoughts
Crystal grades can be useful, but they aren't the final word on a crystal's beauty.
A supplier's grade can tell you something about how that material has been classified, but it can't tell you which crystal you'll fall in love with.
That's why we love choosing our crystals ourselves.
Sometimes it's the exceptionally clear, high-grade specimen that makes us stop in our tracks.
Sometimes it's the crystal full of inclusions that we could happily spend ten minutes examining.
And sometimes it's a little crystal that doesn't tick every traditional quality box but somehow feels like exactly the right one.
There is room for all of them.
Because perhaps the best crystal isn't necessarily the one with the highest grade.
It's the one you can't stop looking at.
