If you've ever shopped for gemstone jewelry and found yourself wondering what natural, lab-created, synthetic, or simulated actually means, you're definitely not alone. The jewelry industry has a lot of terminology, and sometimes I think we make buying something beautiful way more complicated than it needs to be.
Here's what I believe: you shouldn't need to become a gemologist to buy gemstone jewelry. But you should understand what you're paying for.
This is something that's become increasingly important to me as I've learned more about gemstones and become more intentional about what I source for The Always Busy Mama. I work primarily with natural gemstones because I love the idea that these stones were created by the earth, each with its own variations, inclusions, colors, and characteristics. But choosing natural gemstones doesn't mean lab-created gemstones are "fake" or that there's something inherently wrong with choosing them.
They're simply different.
And understanding that difference makes you a much more confident jewelry shopper.
What Is a Natural Gemstone?
A natural gemstone is exactly what it sounds like: a gemstone that formed in nature without human intervention. Depending on the stone and the geological conditions required to create it, that process can take an incredibly long time.
Once the gemstone is recovered, humans obviously become involved. Stones are cut, shaped, polished, and eventually transformed into the gemstones we see in jewelry. Some natural gemstones may also receive treatments to improve characteristics such as their color or clarity, which is another topic we'll dig into more deeply in this gemstone education series.
What I love most about natural gemstones is their individuality.
Two pieces of Rose Quartz may be slightly different shades of pink. One Labradorite may flash brilliant blue while another shows green or gold. Tourmaline can vary tremendously from stone to stone. You might see inclusions, changes in transparency, slight color variations, or patterns created entirely by nature.
For me, those aren't necessarily imperfections.
They're part of the story.
What Is a Lab-Created Gemstone?
Here's where one of the biggest misconceptions comes in.
A lab-created gemstone is not automatically a fake gemstone.
The Gemological Institute of America explains that synthetic, or laboratory-created, gemstones are grown in a laboratory but have essentially the same chemical composition, crystal structure, and optical and physical properties as their natural counterparts. The major difference is where and how they formed: one developed in nature, while the other was created under controlled laboratory conditions.
Take a lab-created ruby as an example. It isn't simply a piece of red glass designed to look like ruby. A laboratory-grown ruby has essentially the same chemical composition and crystal structure as a natural ruby. Gemologists can distinguish natural and synthetic stones through characteristics such as their growth patterns and inclusions, but to the average person looking at a finished piece of jewelry, the distinction may not be obvious.
That's also why you'll sometimes see the words lab-created, laboratory-grown, or synthetic used when describing these gemstones. While "synthetic" may sound like it means fake in everyday conversation, it has a much more specific meaning in gemology.
Lab-Created and Simulated Are NOT the Same Thing
This is probably the distinction I most want you to remember.
A lab-created gemstone is created to have essentially the same chemical, physical, and optical properties as the natural gemstone it represents.
A simulated gemstone, sometimes called an imitation, is something that simply looks like another gemstone but does not have those same properties. GIA defines a simulant as a material used because it resembles another gem, and that material can actually be either natural or man-made.
Cubic zirconia being used in place of a diamond is an easy example. It can give you a similar visual appearance, but cubic zirconia and diamond are different materials.
That doesn't automatically make a simulant bad either. There are plenty of reasons someone may intentionally choose one, including price.
The important word here is intentionally.
You should know what you're buying.
In fact, FTC guidance says sellers should clearly disclose when a gemstone is laboratory-created or simulated rather than mined. Transparency isn't simply something I personally value as a jewelry maker; there are consumer-protection standards around how these materials should be represented.
Why Are Lab-Created Gemstones Usually Less Expensive?
One of the things that makes natural gemstones valuable is rarity.
Nature doesn't allow us to place an order for 100 perfectly matched sapphires in exactly the same shade and clarity. Natural gemstones form under specific conditions, and what comes out of the earth varies.
Laboratory-created gemstones are different because their growth conditions can be controlled. GIA notes that synthetic gemstones can essentially be "made to order" with more consistent color and crystal shape, making them far less rare than comparable natural gemstones.
That difference in rarity is one reason natural and lab-created gemstones can have very different prices even when they look remarkably similar.
And this brings us back to something we talked about in my article about AAA vs. AA gemstone quality: price isn't determined by one factor alone. Rarity, color, clarity, size, cut, treatments, origin, and overall quality can all play a role in what a gemstone is worth.
Does Natural Automatically Mean Untreated?
No, and this is another misconception worth clearing up. A gemstone can be natural and still have been treated.
Gemstone treatments have been used for a very long time to alter or enhance characteristics such as color or clarity. Heat treatment, for example, is commonly associated with certain gemstones. Other types of treatments also exist, and some may affect the value, durability, or care requirements of a stone.
GIA notes that gemstone treatments aren't always obvious to an untrained eye, which is one reason disclosure is so important.
We're going to talk much more about treatments in another article because that topic deserves its own conversation. For now, I simply want you to remember that natural and untreated are not interchangeable terms.
Why Does The Always Busy Mama Choose Natural Gemstones?
For me, this is where gemstone education becomes personal.
I choose to work primarily with natural gemstones because their individuality aligns so beautifully with what The Always Busy Mama represents.
Our jewelry is meant to tell your story.
And your story isn't perfect or mass-produced either.
You've changed. You've grown. You've walked through hard seasons and beautiful ones. There are probably pieces of your life you wouldn't have chosen but that helped shape the woman you are today.
There's something about a natural gemstone that feels incredibly connected to that idea.
I love picking up a strand of gemstones and seeing slight variations from one stone to another. I love the inclusions, the color differences, and the little characteristics that remind you this material came from nature.
It means your gemstone may not look exactly like someone else's.
And I think that's pretty special.
So, Are Natural Gemstones Better Than Lab-Created Gemstones?
I don't think that's the right question.
The better question is: What matters to you?
If owning a gemstone that formed naturally in the earth and carries its own unique characteristics matters to you, a natural gemstone may feel more meaningful.
If you love the look of a particular gemstone but prefer the consistency or price point that can come with a laboratory-created option, there's nothing inherently wrong with making that choice either.
What matters to me is that you aren't paying for a natural gemstone when you're actually receiving something lab-created or simulated.
You deserve transparency.
The Best Gemstone Is the One You Choose With Intention
That's really what this entire gemstone education series comes back to.
I'm not trying to turn you into a gemologist. I'm trying to give you enough information to walk into a boutique, browse jewelry online, or shop with me and understand what you're buying.
Ask whether the gemstone is natural or lab-created. Pay attention to how materials are described. Don't assume "synthetic" necessarily means fake. Understand that "simulated" means something different. And don't be afraid to ask the person selling you jewelry questions.
A good jewelry maker should want you to understand what you're buying.
At The Always Busy Mama, I'll continue choosing natural gemstones because I love their individuality, their history, and the connection they create between the jewelry you wear and the story you're living.
Because ultimately, that's what matters most to me.
Not simply wearing something beautiful.
Wearing something that means something.
