Moissanite, Lab Diamonds, Zircon & Other Stones: A Comprehensive Comparison
Choosing the right gemstone means balancing beauty, durability, ethics, and cost. Here’s a deep dive into the most commonly used alternatives to mined diamonds:
Moissanite
·Brilliance: Exceptional sparkle, even more than diamonds. Famous for its fire (rainbow light reflections).
Durability: 9.25 on the Mohs scale, making it suitable for everyday wear.
Origin: Lab-created (natural moissanite is extremely rare).
Cost: Much more affordable than mined or lab-grown diamonds.
Ethical Factor: Fully ethical, with a minimal environmental footprint.
Ideal for: Those who love sparkle, want durability, and prefer a budget-friendly option.
Lab Grown Diamonds
Brilliance: Identical optical properties to mined diamonds.
Durability: 10 on the Mohs scale — the hardest gemstone.
Origin: Grown in labs using HPHT or CVD methods.
Cost: Typically 30–60% less than mined diamonds of the same grade.
Ethical Factor: More sustainable and traceable than mined stones.
Certification: Often certified by GIA, IGI, or GCAL.
Ideal for: Traditional diamond lovers looking for a modern, ethical alternative.
Cubic Zirconia (CZ)
Brilliance: Good sparkle, though less fire and depth than diamonds.
Durability: Softer (8–8.5 Mohs), more prone to scratches over time.
Origin: Synthetic, mass-produced.
Cost: Extremely affordable.
Ethical Factor: No mining involved; environmentally benign.
Ideal for: Occasional wear or fashion jewellery on a tight budget.
White Sapphire
Brilliance: Subtle sparkle, more understated than diamond or moissanite.
Durability: Very durable (9 Mohs), suitable for daily wear.
Origin: Natural or lab-created.
Cost: Lower than diamonds but higher than CZ.
Ideal for: Those wanting a natural gem with durability and elegance.
Zircon (Not CZ!)
Brilliance: Strong brilliance and fire, often confused with diamonds.
Durability: Softer than sapphire (6–7.5 Mohs), should be worn with care.
