Moissanite vs. Lab Diamonds
When considering the purchase of a lab diamond or moissanite, it's important to understand the key differences between these two popular options. Here’s a comprehensive overview:
| Feature | Lab Diamonds | Moissanite |
|---|---|---|
| Formation and Origin | Created in labs via HPHT or CVD; identical to natural diamonds (pure carbon). | Silicon carbide crystal; originally discovered in meteorites, lab-created. |
| Brilliance and Fire | Comparable to natural diamonds; classic diamond fire. | Exhibits more brilliance and fire due to higher refractive index, often showing a “rainbow” effect. |
| Hardness | Rated 10 on the Mohs scale (hardest substance). | Rated 9.25 on the Mohs scale; very durable but slightly less hard than diamonds. |
| Price | More expensive; price varies based on size, quality, and sourcing. | Typically budget-friendly, offering beauty at a lower cost. |
| Appearance | Classic diamond look; neutral colour with no visible inclusions at normal distance. | Slight colour hint possible; may show double refraction effect. |
| Ethical Considerations | Ethical and conflict-free; created in controlled environments. | Also ethical; produced synthetically without major environmental or human rights issues. |
| Resale Value | Generally holds value better; potential for appreciation. | Lower resale value compared to lab and natural diamonds. |
| Certification | Often comes with certifications from reputable gemological labs (GIA, IGI). | Can be certified, but not always on the same parameters as diamond grading. |
