If you’ve ever paused mid-scroll and wondered, “Wait… are lab-created gemstones real?” you’re not alone. It’s one of the most common questions I get — especially when you’re shopping for jewelry that’s meant to mean something, not just look pretty.
Here’s the reassuring truth: lab-grown gemstones can be real gemstones (same crystal structure + chemical composition as mined stones). The difference is where they form — not whether they’re “fake.”
In this guide, I’ll explain how lab-grown gemstones are made, what hydrothermal quartz actually is, how aura quartz gets its shine, and how to shop with total confidence — no geology degree required.

Are lab-created gemstones real?
Yes — when they’re truly lab-grown. Lab-grown (lab-created) gemstones are crystals produced in a controlled environment using the same crystal structure and same chemical composition as gemstones formed in the earth.
So why the confusion? Because the jewelry world also includes glass imitations, resins, coatings, and treatments — and people often lump everything together under the word “fake.” That’s not fair to shoppers, and it’s not helpful for trust.
The quick truth (30 seconds):
- Lab-grown gemstones are real gemstones — they are crystals, not molded materials.
- They are not glass, resin, or plastic.
- Many people choose lab-grown stones intentionally for clarity + ethics + affordability without sacrificing beauty.
If you love choosing jewelry by symbolism, energy, and vibe… this matters. Because trust is part of the magic.
How lab-grown gemstones are made (HPHT + CVD)
Lab-grown gemstones are created with processes designed to replicate natural crystal growth — just with the variables (heat, pressure, chemistry) carefully controlled.
High-Pressure High-Temperature (HPHT)
HPHT mimics the intense conditions found deep within the earth.
- Temperatures can exceed 1,300°C
- Pressure reaches tens of thousands of atmospheres
- Crystals grow around a “seed” over days to weeks (sometimes longer depending on the material)
This method is commonly used for lab-grown ruby, sapphire, spinel, and some diamonds. The results can have the same durability and hardness as their natural counterparts.
Chemical Vapor Deposition (CVD)
CVD is a modern crystal-growth method often used for diamonds.
- A sealed chamber is filled with carbon-rich gases
- Energy turns the gas into plasma
- Atoms deposit onto a seed crystal layer by layer
Important note: these processes build crystal structure — they aren’t molding material into a shape.
Lab-grown ruby, sapphire & pink spinel
Many vivid colored gemstones are lab-grown to provide consistency, durability, and ethical sourcing.
Lab-grown ruby
Ruby is a variety of corundum colored by chromium. Lab-grown rubies share the same structure and hardness as natural rubies, often with cleaner color and fewer inclusions.
Lab-grown sapphire
Sapphires are also corundum and come in many colors. Lab-grown sapphires can offer rich saturation without the environmental impact of mining.
Lab-grown pink spinel
Spinel is a naturally occurring gemstone often mistaken for ruby. Lab-grown pink spinel is valued for its brilliance, durability, and soft yet vibrant hue.

What is hydrothermal quartz?
Hydrothermal quartz is genuine quartz. It’s grown using a process that replicates how quartz forms in water-rich environments underground — which is why “hydrothermal quartz” is the most accurate term (and the one we recommend using consistently).
How hydrothermal quartz is grown
- Quartz components are dissolved in a heated water solution
- High pressure allows crystals to slowly form over time
- Trace minerals may be introduced during growth to create color
The key point: the result is still quartz crystal — with clarity, durability, and consistent color throughout the stone.

What is aura quartz?
Aura quartz starts as real quartz (natural or lab-grown) and then receives a surface treatment that creates the distinctive iridescent or metallic sheen.
How aura quartz is created
- The quartz is placed in a vacuum chamber
- Metals such as titanium, gold, or platinum are vaporized
- The metal bonds to the surface at a molecular level
This treatment affects the surface — the shimmer is not part of the internal crystal structure. That doesn’t make it “bad.” It just means it deserves respectful care (like plated metals).
Is aura quartz durable?
Aura quartz is stable for normal wear, but the finish can be affected by:
- Harsh chemicals
- Abrasive cleaning
- Repeated friction over time

What is lab-grown rutilated quartz?
Lab-grown rutilated quartz is quartz grown in a controlled environment where rutile-like inclusions are intentionally introduced during the crystal-growth process.
Unlike surface treatments, the “rutilated” effect in lab-grown rutilated quartz is:
- Internal to the stone
- Part of the crystal formation
- Not painted or coated
The result can resemble natural rutilated quartz — often with more consistent thread-like inclusions and clearer quartz. This is one reason lab-grown options can be so popular: they deliver the look while keeping designs durable and accessible.
Lab-grown vs treated vs stabilized stones
This is where a lot of “is it real?” confusion actually lives. Not everything is either “natural” or “fake.” There are several legitimate categories — and the key is transparency.
Lab-grown
- Stone is grown from scratch
- Same chemical composition as natural
- Color/structure are internal
Color-enhanced (treated)
- Natural stones altered through heat, irradiation, or other common industry treatments
- Often stable and widely accepted
- Transparency matters
Stabilized
- Porous natural stones reinforced (often with resin) to improve durability
- Common with softer materials (turquoise is a classic example)
None of these categories are automatically “bad.” The difference is whether the treatment is internal, surface-applied, and whether the seller is clear about it.
How to shop with confidence (the 60-second checklist)
- Ask what it is: natural, lab-grown, or treated (a good brand will tell you clearly).
- Ask what’s internal vs surface: internal color/inclusions wear differently than a surface finish.
- Ask how it wears: is it suitable for everyday life (work, water, friction, cleaning)?
- Ask about care: gentle cleaning + storage protects plated metals and specialty finishes.
- Ask what it means to you: symbolism + intention is the real magic — origin is just one part of the story.

FAQ
Are lab-grown gemstones fake?
No. True lab-grown gemstones are crystals with the same chemical composition and crystal structure as mined gemstones. They’re not glass or resin.
Is hydrothermal quartz real quartz?
Yes. Hydrothermal quartz is genuine quartz grown under controlled conditions that replicate water-rich crystal formation.
Is aura quartz real?
Aura quartz starts as real quartz and receives a surface-bonded metallic finish for its signature shimmer. It’s real quartz with a specialty surface treatment.
Does lab-grown change the “meaning” of crystals?
Meaning comes from symbolism, intention, and how you choose to wear a piece — not only from where a stone formed. Many people choose lab-grown stones because sustainability and transparency are part of their values.
Final thoughts
Natural stones carry history. Lab-grown stones carry intention. Treated stones carry artistry.
There is no single “best” gemstone — only what feels right for you, your values, and how you live. Understanding the differences simply gives you power: you get to choose jewelry you can wear with confidence.
As always: Wear what you love & the rest will follow.
