Diamonds have long been the ultimate symbol of luxury, elegance, and commitment, but not every sparkling gemstone is a natural or lab-grown diamond. Enter diamond simulants—stunning alternatives that mimic the appearance of diamonds while offering their own unique advantages.
But what exactly is a diamond simulant, and how does it compare to a real diamond? In this guide, we’ll explore the characteristics, types, and best uses for diamond simulants, helping you make an informed choice when shopping for fine jewelry.
Understanding Diamond Simulants
A diamond simulant is any gemstone that looks like a diamond but has a different chemical composition and physical properties. While they can be dazzling, they do not share the same hardness, durability, or brilliance as natural or lab-grown diamonds.
- Not a real diamond – Simulants are visually similar but chemically different.
- Different hardness levels – Most are softer than diamonds, making them more prone to scratches over time.
- More affordable – They offer a diamond-like look at a fraction of the cost.
Diamond simulants are a great choice for fashion jewelry, statement pieces, or those looking for a budget-friendly alternative.
How Are Diamond Simulants Different from Natural and Lab-Grown Diamonds?
While all three options sparkle, their differences lie in composition, strength, and longevity.
- Natural Diamonds – Formed deep in the Earth over billions of years, made entirely of carbon.
- Lab-Grown Diamonds – Created in a controlled environment, but chemically identical to natural diamonds.
- Diamond Simulants – Different gemstones (or materials) that only mimic a diamond’s appearance.
Unlike lab-grown diamonds, which are real diamonds, simulants are an entirely different type of gemstone.
Types of Diamond Simulants
Not all diamond simulants are the same. Some are natural gemstones, while others are man-made materials. Here are the most common types:
1. Cubic Zirconia (CZ)
- The most well-known diamond alternative.
- Offers brilliant sparkle but lacks the hardness of a real diamond.
- Tends to lose its shine and become cloudy over time.
Best for: Fashion jewelry and affordable statement pieces.
2. Moissanite
- One of the best diamond simulants in terms of brilliance and fire.
- More durable than cubic zirconia, ranking 9.25 on the Mohs scale.
- Slightly different sparkle, with more rainbow flashes compared to a diamond.
Best for: Engagement rings and fine jewelry that needs extra durability.
3. White Sapphire
- A natural gemstone that can be cut to resemble a diamond.
- Less brilliance than diamonds but offers a soft, elegant glow.
- Can appear slightly cloudy over time if not well-maintained.
Best for: Those who want a natural gemstone alternative to diamonds.
4. Glass Imitations & Synthetic Materials
- Used in costume jewelry, often found in budget accessories.
- Lacks durability and can scratch easily.
- Not recommended for everyday wear.
Best for: Temporary jewelry and decorative accessories.
How to Tell a Diamond from a Simulant
If you’re unsure whether a gemstone is a real diamond or a simulant, consider these quick checks:
- Hardness Test – Diamonds are the hardest substance (10 on the Mohs scale). If a stone scratches easily, it’s not a diamond.
- Brilliance Check – Diamonds reflect white light, while some simulants (like moissanite) show more rainbow-colored flashes.
- Fog Test – Breathe on the stone. Diamonds disperse heat instantly, while simulants may fog up for a few seconds.
- Certification – A real diamond will come with a GIA or IGI certificate confirming its authenticity.

Should You Buy a Diamond Simulant?
Choosing a diamond simulant depends on your needs and priorities. Consider a simulant if you:
- Want the look of a diamond without the cost.
- Need a temporary engagement ring before investing in a real diamond.
- Love experimenting with jewelry styles and want a variety of affordable options.
- Prefer ethical, non-diamond alternatives for your jewelry collection.
For those looking for a long-lasting, heirloom-quality piece, a natural or lab-grown diamond is the better investment.
Caring for Diamond Simulants
To keep your diamond simulant jewelry looking its best:
- Clean regularly – Use mild soap, warm water, and a soft brush to remove buildup.
- Store separately – Keep away from harder gemstones like diamonds to avoid scratches.
- Avoid harsh chemicals – Perfumes, lotions, and cleaning products can dull the sparkle.
- Check settings frequently – Simulants are softer and may need occasional tightening.
Proper care will help extend the beauty and brilliance of your diamond simulant jewelry.
