7 Precious Gemstone Myths
Myth 1: Expensive Gemstones Are Always Genuine
The biggest myth is that price can guarantee the authenticity. Although rare gemstones are expensive, price can’t be the sole factor that ensures whether the stone is natural or not.
Gemstone 5C’s plays an important role in identifying an original stone. Sometimes, a treated or lab-grown gemstone is valued more than a natural gemstone because of quality or jewelry design.
Reality Check
- Certification does not price-confirm authenticity.
- Always compare quality before comparing cost.
- Buy from trusted gemstone sellers.
Myth 2: Bigger Gemstones Are Always More Valuable
A large-sized gemstone catches attention; it can’t decide on overall value. Professional gemologists evaluate types of precious stones using multiple quality factors, not just carat weight alone.
For example, a small-sized ruby with an exception color and clarity can be more worthy than a large-sized ruby with poor transparency or visible inclusions.
What Really Matters?
Instead of just focusing on size, always compare this:
- Color
- Clarity
- Cut
- Rarity
- Overall brilliance
Remember: The quality of the gem almost always outweighs size
Myth 3: Natural Gemstones Never Receive Treatments
Buyers believe that natural gemstones are sold directly after mining. The harsh truth is, several precious gemstones receive treatments to enhance the color and transparency of the stone.
For example:
- Rubies and sapphires are heat-treated to enhance the color of the stone.
- Emerald also undergoes treatment with oil or resins to improve clarity.
- Some gemstones undergo minor enhancements to improve durability or appearance.
Well, although all these gemstones are considered natural in the gemstone industry, till they are not closely disclosed by the seller.
Reality Check
- Natural doesn't always mean untreated.
- Most standard treatments are accepted by the trade.
- Always ask whether the gemstone has been enhanced.

Myth 4: Synthetic Gemstones Are Fake
This is one of the most misunderstood gemstone myths.
A synthetic stone carries the same chemical composition, crystal structure, and optical properties as the original gemstone. Actual differences are created in a laboratory, not in the forming process.
Know the Difference
- Natural gemstone—Formed by nature.
- Synthetic gemstone—Lab-created with the same properties as a natural stone.
- Imitation gemstone—Looks similar but is made from different materials like glass or cubic zirconia.
Reality Check
Not every lab-created gemstone is fake—but every seller should clearly disclose what they're selling.

Myth 5: Every Blue Gemstone Is a Sapphire
Many people often misunderstand that every blue gemstone is blue sapphire. Although there are many stones that look similar, they are not blue sapphire.
Well, every gemstone is natural in its own shade with unique properties, hardness, value, and appearance.
Some Other Famous Blue Gemstones:
- Blue Sapphire Stone
- Aquamarine Gemstone
- Blue Topaz Gemstone
- Tanzanite Gemstone
- Blue Zircon Gemstone
Reality Check
Remember, never identify a gemstone by color. Always check certification and gemstone type before buying.
Myth 6: Precious Gemstones Are Always Better Than Semi-Precious Stones
The precious gemstone myths are always superior to other semi-precious gemstones. The diamond, ruby, sapphire, and emerald are known as precious gemstones. While alexandrite, black opal, or tsavorite garnet are rarer and more valuable than lower-quality precious stones.

Reality Check
A gemstone's quality matters far more than whether it's called "precious" or "semi-precious."
Myth 7: You Don't Need a Gemstone Certificate
Many buyers skip certification to save money or because they trust the seller. Sadly, it may result in purchasing treated, synthetic, or imitation stones without knowing their own identity.
A gemstone certification should be recognized by a gemological laboratory. It ensures the key details about the gemstone, which include:
- Identity
- Natural or synthetic origin
- Treatments (if any)
- Weight and measurements
Reality Check
If you're investing in a valuable gemstone, certification isn't optional—it's one of the smartest parts of the purchase.
How Gemologists Evaluate a Precious Gemstone
Professional gemologists don't rely on myths—they evaluate measurable quality factors.
They look at:
Color – Rich, evenly distributed color is highly desirable.
Clarity – Natural inclusions are common and can indicate natural origin.
Cut – A precise cut enhances brilliance and beauty.
Carat Weight – Size adds value only when paired with good quality.
Treatments – Any enhancements should be clearly disclosed.
Certification – Confirms authenticity and gemstone characteristics.
Expert Insight: A gemstone is never judged by a single feature. Professionals evaluate all quality factors together before determining its value.
