What Is an American Diamond?
American Diamond is a popular term used to describe premium-quality diamond simulants, most commonly cubic zirconia. These stones are engineered to visually resemble natural diamonds while remaining highly affordable.
Key Characteristics of American Diamonds
- Man-made simulant, not a real diamond
- High brilliance and clarity when new
- Significantly lower cost
- Ideal for fashion and daily wear jewelry
What Is a Lab Grown Diamond?
Lab Grown Diamonds are real diamonds created using advanced technological processes that replicate natural diamond formation. Chemically, physically, and optically, they are identical to mined diamonds.
How Lab Grown Diamonds Are Created
- HPHT (High Pressure High Temperature)
- CVD (Chemical Vapor Deposition)
American Diamond vs Lab Grown Diamond: Core Differences
| Feature | American Diamond | Lab Grown Diamond |
|---|---|---|
| Material | Cubic Zirconia (Simulant) | Real Diamond |
| Hardness (Mohs) | 8–8.5 | 10 |
| Brilliance Longevity | Moderate | Permanent |
| Price | Very Affordable | Mid to High |
| Resale Value | None | Limited but present |
Appearance & Brilliance
At first glance, both stones can look stunning. However, under professional lighting and long-term use, differences emerge. American Diamonds often show more rainbow-like flashes, while Lab Grown Diamonds exhibit the crisp white brilliance associated with natural diamonds.
Durability & Hardness
Durability is where Lab Grown Diamonds clearly win. With a Mohs hardness of 10, they resist scratches indefinitely. American Diamonds, while durable, may develop surface wear over years of daily use.
Price & Long-Term Value
If budget is your primary concern, American Diamonds are unbeatable. However, Lab Grown Diamonds offer emotional and intrinsic value closer to natural diamonds, making them suitable for milestone jewelry.
Ethical & Environmental Impact
Both options avoid traditional mining concerns. American Diamonds have minimal environmental impact due to simple manufacturing, while Lab Grown Diamonds significantly reduce ecological and ethical issues compared to mined diamonds.
