Precious, semi-precious stones and crystals are more and more popular, and that unfortunately, means an increase of their counterfeits.
Understanding which stones are most often imitated—and how to spot the signs—can help you make confident and informed choices when shopping for your jewellery or crystal collection.
Let’s explore some of the most commonly counterfeited semi-precious stones and crystals, along with tips on how to identify the real deal.
1. Turquoise
Why it’s counterfeited: Turquoise’s vivid blue-green hues have made it a treasured stone for centuries, but high demand and limited supply have led to frequent counterfeiting.
- Common fakes: Dyed howlite or magnesite, which mimic turquoise’s appearance at a fraction of the cost.
- How to spot the fake: Authentic turquoise is opaque with natural matrix patterns, while dyed stones often show overly bright or uniform colours. A scratch test can reveal the white interior of dyed howlite beneath its surface.

2. Jade
Why it’s counterfeited: Jade’s cultural significance and beauty make it a prized gemstone, especially in its emerald-green variety. However, genuine jadeite is rare and expensive.
- Common fakes: Glass or dyed quartz are often sold as jade. Additionally, low-quality jade is treated with dyes and resins to improve its appearance.
- How to spot the fake: Real jade feels cool to the touch and is denser than glass. Look for irregularities under magnification—perfectly uniform colour can be a sign of artificial treatment.

3. Amethyst
Why it’s counterfeited: Amethyst is a popular quartz variety known for its stunning purple hues, making it a target for imitation.
- Common fakes: Dyed glass or synthetic quartz can be passed off as amethyst.
- How to spot the fake: Genuine amethyst has subtle colour zoning, with lighter and darker areas, whereas fake amethyst often appears overly uniform in colour.

4. Citrine
Why it’s counterfeited: Natural citrine is rare, and much of the citrine on the market is actually heat-treated amethyst or smoky quartz.
- Common fakes: Heat-treated quartz stones, which are less valuable but resemble citrine.
- How to spot the fake: Treated stones often show a more intense orange hue, while natural citrine tends to have a soft yellow or honey-like tone.

5. Garnet
Why it’s counterfeited: Garnet’s deep red hues have made it a classic choice for centuries, but its affordability means it’s often substituted with glass.
- Common fakes: Red glass or composite stones made by fusing materials.
- How to spot the fake: Garnet has a natural brilliance and refractive quality. Use a light to check for internal inclusions—glass fakes often appear too clear.
More about garnet is described in an article written by Rosec Jewels.
6. Lapis Lazuli
Why it’s counterfeited: Lapis lazuli’s rich blue colour, often accented with golden pyrite flecks, makes it a standout stone. However, its popularity has led to widespread imitation.
- Common fakes: Dyed calcite, synthetic materials, or composite stones created from crushed lapis.
- How to spot the fake: Real lapis has subtle variations in its blue tone and visible pyrite inclusions. Fakes are often overly vibrant and lack natural texture.

7. Quartz Crystals
Why it’s counterfeited: Quartz crystals, particularly clear or rose quartz, are widely used in both jewellery and spiritual practices, leading to imitations made from glass.
- Common fakes: Glass replicas often mimic quartz, as well as artificially dyed quartz to create vibrant colours not found in nature.
- How to spot the fake: Real quartz is cool to the touch and heavier than glass. Inspect for air bubbles—these are common in glass but not in natural quartz.

8. Opal
Why it’s counterfeited: Opals are cherished for their iridescent play of colour, making them highly desirable and prone to imitation.
- Common fakes: Synthetic opals or opal doublets, where a thin slice of real opal is bonded to a backing.
- How to spot the fake: Genuine opals display a complex, natural play of colour that changes with light. Synthetic opals often have a uniform, grid-like pattern.

Protect Yourself from Counterfeits
- Buy from reputable sellers: Choose trusted jewellers or crystal retailers with a history of authenticity and transparency.
- Ask for documentation: Request certificates of authenticity, especially for high-value stones.
- Learn about your stone: Research its properties, typical inclusions, and natural variations.
- Conduct tests: Use scratch, density, or light tests to verify the material when appropriate.
Counterfeit stones may dazzle at first glance, but knowing how to identify genuine semi-precious stones ensures that your collection retains its value and authenticity. With a little knowledge and attention to detail, you can confidently invest in beautiful, timeless jewellery and crystals.
