Lab-Created Gemstones: Are Created Rubies, Opals, and Sapphires Real?
Yes, many lab-created gemstones are real gemstones. Lab-created rubies and sapphires have essentially the same chemical composition and crystal structure as their natural counterparts. Their main difference is origin. Natural gemstones form within the earth, while lab-created gemstones grow in controlled environments. Created opals are slightly different because of opal's unique structure, but high-quality lab-created opals can reproduce the distinctive color and play-of-color associated with natural opal.
Gemstones have been treasured for generations because of their color, brilliance, symbolism, and natural beauty. Today, however, some of those same gemstone materials can be grown in carefully controlled laboratories rather than forming deep within the earth.
That leads to an important question for jewelry shoppers: are lab-created gemstones actually real?
In many cases, yes. Lab-created rubies, sapphires, and other gemstones can share the same essential chemical and physical properties as natural stones. The biggest difference is how they came into existence.
What are lab-created gemstones?
Lab-created gemstones are stones grown in controlled environments using processes designed to reproduce the conditions that allow gemstones to form naturally.
Instead of developing underground over long periods of time, the gemstone grows inside specialized equipment where temperature, pressure, chemistry, and other conditions can be carefully managed.
The result is not necessarily an imitation. In many cases, the laboratory-grown gemstone has essentially the same chemical composition and crystal structure as the natural stone it represents.
A lab-created gemstone can be made from the same fundamental material as its natural counterpart. An imitation stone simply resembles another gemstone visually without sharing the same composition.
Are lab-created gemstones considered real?
Yes, many lab-created gemstones are considered real gemstone material because they share the defining chemical, physical, and optical characteristics of the corresponding natural stone.
A lab-created ruby is still corundum. A lab-created sapphire is also corundum. Their origin is different, but the gemstone material itself is fundamentally the same.
This is why terminology matters when shopping for jewelry. Words such as "lab-created," "laboratory-grown," or "synthetic" tell you that the stone was produced in a controlled environment rather than mined from the earth.
That distinction should always be clear so you know exactly what type of gemstone you are purchasing.
Are lab-created rubies real rubies?
Yes. Lab-created rubies are made from corundum, the same mineral that forms natural ruby.
Ruby receives its famous red color primarily from chromium within the material. When ruby is created in a laboratory, scientists reproduce the conditions necessary for corundum crystals to grow while introducing the elements responsible for its red color.
Because the growing environment can be controlled, lab-created rubies often display very consistent color and excellent clarity.
Natural rubies may contain more visible inclusions, mineral crystals, growth patterns, or small fractures created during their geological formation. These features can contribute to a natural stone's individuality and rarity.
Are lab-created sapphires real sapphires?
Yes. Lab-created sapphires have essentially the same mineral composition as natural sapphires.
Ruby and sapphire are actually closely related because both belong to the corundum mineral family. Red corundum is classified as ruby, while gem-quality corundum in other colors is generally classified as sapphire.
Blue remains the color most strongly associated with sapphire, but sapphires can appear in many shades. Laboratory methods can produce a variety of these colors while maintaining the fundamental properties of sapphire.
Because sapphire is naturally a very hard gemstone, lab-created sapphires can also be well suited to jewelry designed for frequent wear.
Both ruby and sapphire are varieties of corundum. Their colors come from different trace elements within the gemstone, which is why these two very different-looking stones are actually closely related.
Are lab-created opals real opals?
Lab-created opals require a slightly different explanation because opal has a different internal structure from crystalline gemstones such as ruby and sapphire.
Natural opal forms when silica-rich water moves through cracks and spaces in rock. As the water gradually disappears, microscopic silica particles can remain behind.
When those particles form an orderly internal structure, light can interact with them to create the shifting flashes of color known as play-of-color.
Lab-created opals are produced using methods designed to reproduce many of these structural and visual characteristics.
High-quality created opals can display beautiful flashes of blue, green, pink, orange, red, and other colors depending on the material and pattern.
What is the difference between lab-created and simulated gemstones?
The difference comes down to what the stone is actually made from.
A lab-created gemstone is produced to have essentially the same composition and properties as its natural counterpart. A simulated gemstone is a different material chosen because it looks similar.
| Gemstone Type | Origin | Material |
|---|---|---|
| Natural Gemstone | Forms through geological processes | Natural gemstone material |
| Lab-Created Gemstone | Grown under controlled laboratory conditions | Essentially the same material as the natural gemstone |
| Simulated Gemstone | Manufactured or selected to imitate another stone | Different material with a similar appearance |
How are lab-created gemstones made?
There is no single method used to create every laboratory gemstone.
Different processes use combinations of heat, pressure, mineral ingredients, chemical solutions, and carefully controlled cooling or crystal growth.
Some methods begin with melted material that gradually forms a crystal as it cools. Others grow gemstones from a solution over time.
The method used can influence color distribution, clarity, internal growth patterns, and the overall appearance of the finished gemstone.
Although laboratory growth happens much faster than natural geological formation, producing attractive gemstones still requires precise control throughout the process.
Do lab-created gemstones look different from natural gemstones?
Often, the differences are difficult to identify with the unaided eye.
High-quality lab-created gemstones can closely resemble natural stones in color, brilliance, transparency, and overall appearance.
Laboratory-grown gemstones may sometimes look cleaner because their growing environment can reduce some of the inclusions commonly found in natural gemstones.
Natural stones frequently contain tiny internal characteristics such as mineral inclusions, fractures, color zoning, or irregular growth patterns created during formation.
Laboratory gemstones can have their own growth patterns as well. Gemologists may use magnification and specialized equipment to study these characteristics and determine a stone's origin.
A beautiful, clear gemstone is not automatically lab-created, and a gemstone with inclusions is not automatically natural. Clear product descriptions and professional gemological testing are more reliable than appearance alone.
Are lab-created gemstones durable?
Durability depends primarily on the gemstone itself rather than whether it formed naturally or in a laboratory.
Lab-created rubies and lab-created sapphires share the same basic mineral structure as natural corundum, so they also offer excellent hardness.
That makes them practical choices for rings, earrings, necklaces, bracelets, and other jewelry that may be worn frequently.
Opal is naturally more delicate. Both natural and created opal materials generally require more careful handling because they can be more vulnerable to scratching and impact than ruby or sapphire.
Why do people choose lab-created gemstones?
There are several reasons someone may prefer lab-created gemstones over natural alternatives.
- Color: Controlled growing conditions can produce vibrant and consistent gemstone colors.
- Clarity: Laboratory-created stones may contain fewer visible inclusions.
- Price: Created gemstones are typically more affordable than comparable natural stones.
- Size: Larger gemstones may be available at more accessible prices.
- Consistency: Specific colors, shapes, and sizes can often be sourced more predictably.
For someone primarily interested in color and design, a laboratory-created gemstone can offer a beautiful centerpiece without the price associated with an equally impressive natural stone.
Are lab-created gemstones less valuable than natural gemstones?
Generally, yes. Natural gemstones and lab-created gemstones usually occupy different parts of the jewelry market.
Part of a natural gemstone's value comes from scarcity. It must form under the correct geological conditions, be discovered, mined, sorted, cut, and polished before becoming jewelry.
Exceptional natural rubies and sapphires can be particularly valuable when they combine desirable color, clarity, size, and rarity.
Lab-created gemstones can be produced more consistently, so their supply is not restricted in the same way. This generally results in lower pricing.
That difference in market value does not determine whether a gemstone is beautiful or meaningful. It simply reflects differences in origin, scarcity, and supply.
How can you tell if a gemstone is lab-created?
It can be difficult to determine a gemstone's origin simply by looking at it.
Gemologists may examine inclusions, growth patterns, fluorescence, trace elements, and other internal characteristics using specialized equipment.
Certain patterns can provide clues about whether a gemstone developed naturally or under laboratory conditions.
For everyday jewelry shopping, one of the most practical tools is the product description. Jewelry should clearly state whether its gemstones are natural, lab-created, synthetic, or simulated.
Are lab-created gemstones good for everyday jewelry?
They can be an excellent choice, especially when the gemstone itself is naturally durable.
Lab-created sapphires and rubies are particularly well suited to frequent wear because corundum is one of the harder gemstone materials commonly used in jewelry.
Earrings and pendants are also naturally protected from some of the impacts that rings and bracelets experience, making many gemstone types suitable for those designs.
Opal jewelry deserves more care because of the stone's more delicate nature.
As with natural gemstones, the design of the setting is also important. Secure prongs, smooth edges, dependable clasps, and thoughtful construction all help protect the stone during wear.
How should you choose between natural and lab-created gemstones?
Start with what matters most to you.
If geological origin, rarity, and natural individuality are especially meaningful, you may prefer a natural gemstone.
If your priorities are vibrant color, clarity, size, and approachable pricing, a lab-created stone may be a better fit.
You should also consider how the jewelry will be worn. An everyday ring may benefit from the durability of ruby or sapphire, while a delicate opal pendant can be a beautiful choice for someone who does not mind giving the stone a little extra care.
Neither option has to be universally better. They simply offer different combinations of origin, rarity, appearance, and price.
So, are lab-created rubies, opals, and sapphires real?
In many cases, yes.
Lab-created rubies and lab-created sapphires have essentially the same chemical composition and mineral structure as natural ruby and sapphire.
Lab-created opals are produced differently because of opal's unusual internal structure, but high-quality created opals can reproduce many of the visual qualities that make natural opal so distinctive.
The most important thing is knowing what you are purchasing. Natural, lab-created, and simulated stones are different categories, and jewelry descriptions should make those differences clear.
Once you understand the distinction, the choice becomes personal. Some people love the geological story behind a natural stone. Others prefer the color, clarity, size, or accessibility available through lab-created gemstones.
Either way, the meaning of jewelry ultimately comes from the person wearing it and the moments connected to the piece.
