How to Grade Crystals

This topic actually came from a comment on TikTok after I originally created this course, and I knew it deserved a place here—because it’s something almost every new seller wonders about.

Crystal grading, like AAA, AA, A, B, C, and D is completely subjective. While there are general, unspoken industry norms, there is no official or regulated system. In reality, grading in the crystal world is fluid it’s very much the Wild Wild West.

Because of this, it’s important to understand that grades are not universal they are seller-defined.

The best way to begin understanding grading is to research each mineral you source and pay attention to how different suppliers describe quality. Over time, your eye will naturally develop.

That said, you do not need to use grading labels in your shop to be successful. Many highly reputable shops don’t use them at all. What matters most is how clearly and honestly you communicate the quality of your pieces.

In the video, I walk through an example of how I would personally grade Citrine so you can see this in practice.

At Bella Luna we loosely borrow from the Gemological Institute of America (GIA) “4 C’s,” although this is not a strict rule in the crystal space. The 4 C’s are:

• Cut
• Clarity
• Color
• Carat

In the crystal community, we don’t typically use carats, instead, we measure in grams or kilograms, but clarity, color, and overall formation can serve as helpful reference points when assessing quality.

For example, rutile-included quartz can vary significantly in appearance and grade. A higher-grade (AAA) piece would typically have:

• High clarity
• Minimal cloudiness
• Well-defined, visually striking rutile inclusions

However, grading isn’t just about appearance, it’s also influenced by rarity and availability. In some cases, a crystal may be considered “high grade” simply because it is difficult to source.

Because there are thousands of minerals, it’s not possible to define grading for each one, but this framework will give you a strong, intuitive foundation.

Most importantly, remember this:

Clarity in your descriptions will always matter more than labels.

Instead of relying solely on grades like “AAA,” you can describe your pieces in a way that builds trust and connection with your customers. For example:

• “High clarity with minimal inclusions”
• “Deep, saturated color with natural variations”
• “Beautiful internal texture with visible inclusions”

This approach educates your customer and it positions your brand as transparent, intentional, and elevated.

And the truth is, you can build a highly successful crystal business without using grading labels at all.
