Two Ethical Alternatives Compared
Both moissanite and lab-grown diamonds offer conflict-free, environmentally conscious alternatives to mined diamonds. Understanding their differences helps you make the right choice for your needs and budget.
Price Comparison
Moissanite costs 80-90% less than lab-grown diamonds of comparable size and quality. Lab-grown diamonds, whilst cheaper than mined diamonds, still carry premium pricing. Moissanite delivers maximum value.
Optical Properties
Lab-grown diamonds match natural diamond's refractive index (2.42), whilst moissanite exceeds it (2.65). Moissanite produces more fire and rainbow flashes; lab-grown diamonds offer traditional diamond aesthetics.
Hardness and Durability
Lab-grown diamonds score 10 on the Mohs scale; moissanite scores 9.25. Both are exceptionally durable for daily wear, with negligible practical difference for jewellery applications.
Resale Value Considerations
Neither moissanite nor lab-grown diamonds hold significant resale value compared to natural diamonds. If you're purchasing jewellery to wear and enjoy rather than as an investment, this distinction is irrelevant.
Environmental Impact
Both options are environmentally superior to mining. Lab-grown diamonds require more energy to produce than moissanite, making moissanite the greener choice overall.
The Smart Choice
For maximum brilliance, value, and sustainability, moissanite leads. For those who specifically want a diamond (even lab-created), lab-grown diamonds offer that option. Both are excellent ethical choices.
