Not all diamond alternatives are created equal. This guide compares the most popular simulants across brilliance, durability, and value.
What Is a Diamond Simulant?
A diamond simulant is any gemstone that resembles diamond but has different chemical composition. Moissanite, cubic zirconia, and white sapphire are the most common alternatives.
Side-by-Side Comparison
TABLE:
| Property | Moissanite | CZ | White Sapphire |
|---|---|---|---|
| Hardness | 9.25 | 8.0-8.5 | 9.0 |
| Refractive Index | 2.65 | 2.15-2.18 | 1.77 |
| Dispersion | 0.104 | 0.065 | 0.018 |
| Durability | Excellent | Good | Very Good |
| Cost (1ct) | $50-150 | $5-20 | $100-300 |
Why Moissanite Stands Out
Moissanite is the only simulant that exceeds diamond in fire (dispersion), creating more color flashes. Its 9.25 hardness ensures lifetime durability. CZ is affordable but scratches easily and may cloud over time. White sapphire is durable but has much less brilliance.
Recommendation for Bespoke Pieces
For custom jewelry meant to last, moissanite is the clear choice among simulants. It offers the best combination of brilliance, durability, and value.
Frequently Asked Questions
Does CZ look fake?
High-quality CZ can look convincing when new, but it scratches and clouds more easily than moissanite, revealing its nature over time.
Is white sapphire a good alternative?
White sapphire is durable but lacks the fire and brilliance of moissanite. It appears more 'sleepy' under light.
