If you're shopping for a ruby in Dubai or Ras Al Khaimah, you'll come across two very different products wearing the same name: natural ruby and synthetic (lab-created) ruby. Both are genuine corundum, both can look stunning, and to the naked eye, they can be almost impossible to tell apart. The catch is that they're worlds apart in rarity, value, and what you're actually paying for.
This guide walks you through exactly how natural and synthetic rubies differ, the visual cues gemologists look for, and - most importantly - why a certificate is the only way to know for certain what you're buying.
What's the Real Difference Between Natural and Synthetic Ruby?
A natural ruby forms inside the earth over millions of years, under intense heat and pressure, and is later mined. Every natural stone carries the marks of that slow, chaotic formation process - which is exactly what gives each gem its individuality.
A synthetic ruby - also called lab-created ruby or lab-grown ruby - has the same chemical composition and crystal structure as its natural counterpart, but it's grown in a laboratory over a matter of weeks. It isn't a fake in the sense of being a different material - it's real corundum - but it's manufactured, not mined, and its rarity and value are nowhere near those of a natural stone.
This is the core of the natural ruby vs synthetic ruby question: same chemistry, completely different origin story, and a very different price tag.
5 Ways to Tell a Natural Ruby from a Synthetic One
-
Inclusions Natural rubies almost always contain tiny internal characteristics - fine needle-like inclusions (often called "silk"), small mineral crystals, or subtle growth patterns. These aren't flaws; they're proof of natural formation. A lab-created ruby, by contrast, is often unusually "clean" internally, sometimes with curved growth lines that don't occur in nature.
-
Color Consistency Natural corundum typically shows gentle color zoning - slightly uneven color distribution across the stone. Its lab-grown counterpart tends to have an almost too-perfect, uniform color from every angle, which can actually be a red flag rather than a selling point.
-
Price Point This is often the fastest tell. A natural gem commands a significant premium per carat, especially in finer qualities, while the synthetic version is inexpensive and price-stable regardless of size or clarity. If a "natural ruby" is priced like a lab-created one, that's worth questioning before you buy.
- UV Light Reaction Under ultraviolet light, some lab-created stones fluoresce differently than natural ones, depending on their origin and treatment. This isn't a reliable DIY test on its own, but gemologists use it alongside other checks.
- Certification This is the only method that gives you certainty. Visual and price cues are useful indicators, but a GIA, GRS, or IGI certificate is the definitive way to confirm whether a stone is natural, its treatment history, and its exact specifications.
Why a GIA/GRS/IGI Certificate Is the Only Real Proof
Inclusions, color, and price are helpful signals - but none of them are conclusive on their own. Treated stones, high-quality synthetics, and skilled cutting can all blur the visual lines even for experienced buyers.
A certificate from a recognised lab like GIA (Gemological Institute of America), GRS, or IGI verifies:
- Whether the corundum is natural or lab-created
- Any treatments the stone has undergone (heat treatment is common and disclosed, not a defect)
- Exact carat weight and measurements
- The species and variety of the gemstone
At Rasikh Gems & Jewellers, every natural gemstone we sell - rubies included - is independently certified by GIA, GRS, or IGI. You don't have to take our word for it; the certificate is yours to verify.
How to Read a Ruby Certification Report
When you receive a certificate with your purchase, check for these key fields:
- Species & Variety - confirms it's corundum, variety ruby
- Treatment - states clearly if the stone is heat-treated, untreated, or otherwise enhanced
- Origin (where stated) - some certificates note likely geographic origin
- Carat Weight & Measurements - should match the physical stone exactly
- Report Number - allows you to verify the certificate directly with the issuing lab's database
If a seller can't provide this documentation, or is reluctant to let you verify it independently, treat that as a warning sign.
Natural Ruby vs. Synthetic Ruby: Price Comparison
Pricing for the natural gem varies widely based on origin, color saturation, clarity, and treatment history - fine-quality natural rubies are among the most valuable colored gemstones in the world. The lab-created version, by comparison, is mass-produced and priced accordingly - a fraction of the cost, with little to no variation based on "quality" in the way natural stones are valued.

Buying Natural Ruby in Dubai - What to Check Before You Purchase
The UAE has a large and reputable gemstone market, but as with any region known for jewellery trade, doing your own diligence pays off. Before buying:
- Ask for certification - GIA, GRS, or IGI, not a generic in-house lab report
- Verify the certificate independently - most labs allow you to check report numbers on their own website
- Buy from a seller with a physical presence - a real store in Dubai or Ras Al Khaimah you can visit, not just an online listing
- Compare price against market range - an unusually low price on a "natural, untreated ruby" deserves extra scrutiny

Frequently Asked Questions
Q: What is the difference between Natural ruby and synthetic ruby?
A: A natural ruby is formed naturally within the Earth over millions of years, making it rare, valuable, and unique. A synthetic ruby is created in a laboratory with the same chemical composition but lacks the rarity and long-term value of a natural ruby. For investment, fine jewellery, and astrological purposes, a certified natural ruby is the preferred choice.
Q: Does a natural ruby always have inclusions?
A: Almost always, yes - some level of internal characteristics is expected in natural rubies. A stone that's completely flawless under magnification is worth extra scrutiny.
Q: Can a lab-created ruby pass a certification test?
A: No. Reputable labs like GIA, GRS, and IGI can reliably distinguish natural from synthetic corundum using advanced testing methods, and the certificate will state this clearly.
Q: How much does a natural ruby cost compared to a lab-created one?
A: Natural ruby is significantly more expensive, with pricing driven by color, clarity, origin, and carat weight. The lab-created version is priced low and stays fairly consistent regardless of these factors.
Q: Is a lab-created ruby considered "fake"?
A: Not exactly - it's real corundum with the same chemical makeup as a natural ruby, just grown in a lab rather than formed naturally. It's not the same as a glass or paste imitation, but it's also not a substitute for a natural stone in terms of rarity or value.
Q: Do all jewellers in Dubai sell certified natural rubies?
A: No. Certification practices vary by seller, which is exactly why it's worth confirming before you buy - ask specifically for a GIA, GRS, or IGI report.
Q: Is a GIA certificate necessary when buying a ruby?
A: It's not legally required, but it's the most reliable way to confirm what you're actually purchasing, and it protects your investment for resale, insurance, or future valuation.
Final Thoughts
Natural rubies and their lab-created counterparts can look nearly identical, but they're fundamentally different purchases. If you're buying a ruby as an investment, for its rarity, or simply want certainty about what you're wearing, certification isn't optional - it's the only real proof.
At Rasikh Gems & Jewellers, every ruby we sell is independently certified by GIA, GRS, or IGI, so you can verify it yourself.
