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.
