When shopping for diamond jewelry, especially engagement rings, two popular alternatives to mined diamonds are moissanite and lab-grown diamonds. Both provide more affordable and ethical options but have distinct differences in appearance, origins, durability, pricing, etc. This guide will compare moissanite vs. lab diamonds to help you choose between these stunning center stones.
| Criteria | Moissanite | Lab Diamond |
|---|---|---|
| Appearance and Sparkle | Distinctive brilliance and fire that exceeds even diamonds. Rainbow-like dispersion and brighter flashes of light. | Same optical qualities as mined diamonds. Exceptional brilliance and "hearts and arrows" patterns. |
| Origins and Production | Mineral found in some meteorites, composed of silicon carbide. Most used in jewelry is man-made. | Grown using advanced HPHT or CVD methods. Control over the finished diamond's appearance and allows for sustainable practices. |
| Durability | Hardness of 9.25 on the Mohs scale. Resistant to scratches, chipping, and breaking over time. | Same durability as natural diamonds. Ranks highest at 10 out of 10 on the Mohs scale. |
| Price | Up to 90% less expensive than mined diamonds of comparable sizes and grades. | 30-40% cheaper than mined counterparts. Costs projected to keep dropping over the next decade. |
| Recommended Use in Jewelry | Best for accent stones on a ring's band or halo where capturing rainbow fire is desirable. | Ideal for the central engagement ring stone. Captures the classic elegance and sophistication that diamond jewelry is known for. |
What Are the Differences Between Moissanite and Lab Diamond?
Appearance and Sparkle
Lab diamonds have the same optical qualities as mined diamonds. When cut precisely, they exhibit exceptional brilliance and "hearts and arrows" patterns. Those desiring the classic look of a diamond will find it in a lab-grown alternative. It comes down to personal preferences for a dazzling rainbow sparkle or a crisp white brilliance.
The most noticeable difference between moissanite and lab diamonds is their visual properties. Moissanite has a distinctive brilliance and fire that exceeds even diamonds. Its refractive index results in a rainbow-like dispersion and brighter flashes of light. This unique sparkle is part of moissanite's appeal.
Origins and Production
The origins of these two gemstones also set them apart. Lab diamonds utilize advanced production techniques involving HPHT (high pressure, high temperature) or CVD (chemical vapor deposition) methods to grow diamonds above or below the earth's surface. This enables control over the finished diamond's appearance and allows for sustainable practices.
Moissanite is a mineral found in some meteorites, composed of silicon carbide. Most moissanite used in jewelry is man-made, efficiently producing large, flawless crystals. The manufacturing process is considered environmentally friendly.
Both moissanite and lab diamonds have ethical sourcing, unlike some mined diamonds, which carry potential environmental and humanitarian risks. This gives consumers peace of mind about their jewelry's creation.

Durability Compared
Durability is a major factor for an engagement ring or everyday jewelry. On the Mohs scale of mineral hardness, diamond ranks highest at 10 out of 10. Moissanite comes in at 9.25, with excellent hardness as well.
Lab diamonds have the same durability as natural diamonds, providing impressive strength and edge retention. They are built to last through daily wear as an extremely durable material.
Moissanite's hardness makes it resistant to scratches, chipping, and breaking over time. While moissanite is slightly softer than diamond, it still holds up beautifully as jewelry. For practical purposes, both can be worn worry-free.
Price Differences
Lab diamonds run around 30-40% cheaper than their mined counterparts. With continued advances in production technology and improved efficiency, the costs are projected to keep dropping over the next decade. The price for any diamond varies based on the 4Cs of cut, clarity, color, and carat.
Cost is often the most pressing question when shopping for diamond alternatives. High-quality moissanite is up to 90% less expensive than mined diamonds of comparable sizes and grades. The price difference can amount to thousands in savings, especially on larger stones.
How to Choose Engagement Rings Between Moissanite and Lab Diamond?
When selecting a stone for an engagement ring, moissanite, and lab diamonds work beautifully in different ways. For accent stones on a ring's band or halo, moissanite's sparkle adds striking pops of brilliance. The rainbow flashes surrounding a center diamond can make it pop.
Meanwhile, lab diamonds are an ideal option for the central engagement ring stone. A high-quality lab diamond allows a large, eye-catching diamond to be the focal point without breaking the budget. With an identical structure to mined diamonds, they bring classic elegance to this meaningful jewelry piece.
Ultimately, choosing moissanite or lab diamond depends on budget and style preferences. Setting a spending limit and selecting a design aligned with your personality is recommended over fixating on "traditional" engagement ring standards.
Which is Better: Moissanite or Lab Diamond?
When selecting a stone for an engagement ring or other fine jewelry, lab diamonds are generally the better option over moissanite.
Moissanite:
- Provides immense sparkle and rainbow fire.
- Best for fashion jewelry or accent stones where capturing rainbow fire is desirable.
Lab diamond:
- Captures the classic elegance and sophistication that diamond jewelry is known for.
- Looks identical to mined diamonds in optics, structure and durability.
- Recommended for the central focal stone in an engagement ring or pendant.
- Can be passed down for generations or reset into new designs over time.
Overall, lab diamonds provide better long-term value compared to moissanite.
Conclusion
Moissanite and lab-grown diamonds offer unique advantages compared to conventional mined diamonds. Key considerations are differences in visual properties, production methods, durability, cost savings, and styling options. For many, eco-friendly sourcing provides added appeal. By understanding these key contrasts between moissanite and lab diamonds, shoppers can decide which aligns best aesthetically and financially. Take time to explore designs and set an appropriate budget. With an informed decision, you will surely end up with a gorgeous, ethically sourced forever piece.
