Choosing the perfect gemstone can feel confusing, especially when terms like simulated diamonds, synthetic diamonds, and moissanite get mixed together. This post breaks down everything you need to know about Simulated vs Synthetic Diamonds, helping you make a clear, confident decision, while also exploring why Nakshu Jewels’ Moissanite Jewelry is becoming a loved choice for modern buyers.
Understanding the Difference Between Simulated and Synthetic Diamonds
Knowing what you’re buying is more important than ever. These words sound similar, but they’re completely different in meaning, quality, and value.
What Are Simulated Diamonds?
Simulated diamonds are stones that look like diamonds but are not diamonds in composition. They mimic appearance only, not structure.
Common Types of Simulated Stones
-
Cubic Zirconia (CZ)
Affordable, sparkly, but prone to scratches and dullness. -
Glass Stones
Cheapest option with very low durability. -
White Sapphire
Natural but noticeably less brilliant. -
Moissanite (IMPORTANT NOTE)
Often labeled a “simulant,” but its durability, brilliance, and fire exceed most stones, making it a premium simulant and the best modern alternative.
Simulants are ideal for budget-friendly or fashion-forward jewelry pieces, but quality varies widely.
What Are Synthetic Diamonds?
Synthetic diamonds, often called lab-grown diamonds, are real diamonds created in a controlled lab environment. They have the same physical, chemical, and optical properties as mined diamonds.
HPHT vs CVD Lab-Grown Diamonds
-
HPHT (High Pressure High Temperature):
Mimics how diamonds form underground. -
CVD (Chemical Vapor Deposition):
Creates diamonds layer by layer in a chamber.
Both are real diamonds, the main difference is just how they're grown.
Key Differences: Simulated vs Synthetic Diamonds
| Category | Simulated Diamonds | Synthetic (Lab-Grown) Diamonds |
|---|---|---|
| What They Are | Materials made to look like diamonds but not made of carbon and not true diamonds. | Real diamonds grown in a lab with the same carbon crystal structure as natural diamonds. |
| Chemical Composition | Varies (e.g., CZ = zirconium oxide; Moissanite = silicon carbide). | Pure carbon (C), same as natural diamonds. |
| Crystal Structure | Not diamond structure; depends on material. | Genuine diamond cubic crystal structure. |
| Optical Properties | Often more sparkly or colorful; different brilliance and fire than real diamonds. | Indistinguishable from natural diamonds to the naked eye; same refractive index and brilliance. |
| Durability (Mohs Hardness) | CZ ≈ 8–8.5; Moissanite ≈ 9.25. Less durable than diamonds (except Moissanite is close). | Hardness = 10 (same as natural diamond). Extremely durable. |
| Will It Scratch Easily? | More prone to scratching and clouding over time (CZ especially). | Extremely scratch-resistant—same longevity as natural diamonds. |
| How They’re Made | Manufactured materials created in factories (not using diamond-growth methods). | Grown using CVD or HPHT processes that replicate natural diamond formation. |
| Cost | Very inexpensive ($10–$300). | Less expensive than natural diamonds but still premium ($500–$10,000+ depending on size/quality). |
| Value/Resale | Little to no resale value. | Retains some resale value, similar to natural diamonds, but generally lower resale pressure. |
| Certification | Typically not certified by diamond labs. | Can be certified by GIA, IGI, AGS, etc., just like natural diamonds. |
| Detectable With Tools? | Easily identified as non-diamond using basic gem testers. | Requires advanced laboratory testing to distinguish from natural diamonds. |
| Ethical/Sustainability Profile | Considered ethical, but depends on material production practices. | Highly ethical and environmentally cleaner than mined diamonds, though energy use varies. |
| Best For | Fashion jewelry, budget options, temporary engagement rings, travel jewelry. | Engagement rings, fine jewelry, long-term wear—same use cases as natural diamonds. |
Why Moissanite Outshines Both Simulated and Synthetic Diamonds
Moissanite isn’t just a “diamond look-alike.” It’s a luxury gemstone in its own right, known for extraordinary fire, durability, and sparkle.
Brilliance and Fire
Moissanite has 2.5× more fire than diamonds, giving it a rainbow-like sparkle that stands out.
Durability and Daily Wear
With a hardness of 9.25, it’s suitable for engagement rings and everyday jewelry.
Moissanite vs Lab-Grown Diamonds
| Feature | Moissanite | Lab-Grown Diamonds |
|---|---|---|
| Brilliance | Higher | Moderate |
| Price | Lower | Higher |
| Durability | Excellent | Excellent |
| Eco-Friendliness | Very high | Very high |
Moissanite vs CZ
CZ loses shine over time, Moissanite keeps sparkling for life.
