Mined vs. Lab-Grown Diamond Testing
At Canadian Expert Jewellery, we understand that every diamond tells a story — whether it’s naturally mined over millions of years or created in a laboratory with advanced technology. To ensure authenticity, quality, and peace of mind, we offer professional diamond testing and verification for both mined and lab-grown stones.
Knowing the origin of your diamond is important for valuation, insurance, and personal confidence. Our expert jewellers use precise testing methods to confirm whether a diamond is naturally mined or lab-grown, without compromising the integrity of your piece.
Why Testing Matters
Mined diamonds and lab-grown diamonds can look identical to the naked eye, but their origins, value, and sometimes composition differ. Professional testing provides:
- Accurate identification of mined vs. lab-grown diamonds
- Verification of authenticity and certification
- Confidence for resale, insurance, or personal knowledge
- Insight into quality, cut, clarity, and carat weight
Whether you’re designing a custom engagement ring, purchasing an investment diamond, or inheriting a family piece, testing ensures you know exactly what you own.
Our Diamond Testing Process
- Visual and Microscopic Inspection – We examine inclusions, growth patterns, and optical properties.
- Advanced Electronic Testing – Using specialized instruments, we analyze the diamond’s unique light and thermal properties.
- Certification Verification – We cross-check with GIA, IGI, or other recognized certificates to confirm authenticity and grading.
- Optional Laboratory Analysis – For high-value or rare diamonds, we can provide detailed lab analysis that documents the diamond’s origin and quality.
After testing, you receive a clear, written assessment detailing whether the diamond is mined or lab-grown, along with any relevant information on cut, clarity, color, and carat.
Mined vs. Lab-Grown: Making the Right Choice
Both mined and lab-grown diamonds offer their own unique benefits. Mined diamonds carry natural history and rarity, while lab-grown diamonds offer ethical sourcing and often more affordable options. By testing your diamond, you gain transparency and confidence in your choice, ensuring your jewellery reflects both your taste and values.
