The Diamond, Revealed.
An education in brilliance — understanding the stone that has captivated humanity for centuries, and the mastery behind its future.
What Is a Caratoir Diamond?
A Caratoir diamond is a real diamond — created in a controlled environment using the same carbon, pressure, and heat that the earth employs over billions of years. Same crystal structure. Same hardness. Same fire. The only difference is the address of its creation.
HPHT
High-Pressure High-TemperatureThis method mimics the natural diamond formation process. A diamond seed is placed in carbon, then exposed to extreme heat (around 1,500°C) and pressure (1.5 million PSI). The carbon melts and forms a diamond around the seed.
CVD
Chemical Vapor DepositionA diamond seed is placed in a sealed chamber and filled with carbon-rich gas (usually methane). The gas is heated until carbon atoms separate and deposit onto the seed, building the diamond layer by layer.
Are They Real Diamonds?
Oui. Absolument. Sans équivoque.
Lab grown diamonds ARE:
- Made of pure crystallized carbon
- Optically identical to mined diamonds
- Chemically identical to mined diamonds
- Physically identical to mined diamonds
- Graded using the same 4Cs
- Certified by the same gemological institutes
Lab grown diamonds are NOT:
- Cubic zirconia (a synthetic material)
- Moissanite (silicon carbide)
- Crystal or glass simulants
- "Fake" diamonds
Lab Grown vs. Mined: The Comparison
| Aspect | Lab Grown | Mined |
|---|---|---|
| Composition | Pure carbon | Pure carbon |
| Hardness | 10 Mohs | 10 Mohs |
| Brilliance | Identical | Identical |
| Formation Time | 1-4 weeks | Millions of years |
| Price | 40-70% less | Traditional markup |
| Environmental Impact | Minimal | Mining required |
| Certification | IGI/GIA | IGI/GIA |
Why Choose Lab Grown?
Value
Get a larger, higher-quality diamond for your budget. Or get the same diamond and save significantly.
Ethics
No mining means no conflict concerns. Lab grown diamonds are guaranteed conflict-free.
Environment
No earth displacement, no mining operations. A more sustainable choice.
Quality
Lab conditions allow for greater control, often resulting in fewer inclusions and better color.
The 4Cs Guide
Understanding the four characteristics used to evaluate every diamond.
Cut
Most Important
Cut determines how well the diamond reflects light. It's the most important factor in a diamond's beauty.
Tip: Don't compromise on cut. An excellent cut can make a lower color or clarity grade appear more brilliant.
Color
Very Important
Diamond color grades measure the absence of color. The scale runs from D (colorless) to Z (light yellow/brown).
Tip: G-I offers the best balance of quality and value. Most people can't distinguish from D-F.
Clarity
Important
Clarity measures the presence of inclusions (internal) and blemishes (external).
Tip: VS2 and SI1 often appear "eye clean"—no visible inclusions to the naked eye—at significant savings.
Carat
Personal Preference
Carat measures diamond weight, not size (though they correlate).
Tip: Diamonds just under popular weights (0.9ct vs 1.0ct) offer better value with minimal visual difference.
Ring Size Guide
How to Measure
Method 1: Existing Ring
Measure the internal diameter of a ring that fits the intended finger.
Method 2: String/Paper
Wrap string or paper around the finger, mark where it meets, and measure the length.
Method 3: Professional
Visit a local jeweler for professional sizing.
Size Chart
| US Size | Diameter (mm) | Circumference (mm) |
|---|---|---|
| 4 | 14.9 | 46.8 |
| 5 | 15.7 | 49.3 |
| 6 | 16.5 | 51.8 |
| 7 | 17.3 | 54.4 |
| 8 | 18.1 | 56.9 |
| 9 | 18.9 | 59.5 |
| 10 | 19.8 | 62.1 |
Tips for Accurate Sizing
- Fingers swell in heat; measure at normal temperature
- Measure at the end of the day when fingers are largest
- Wider bands require slightly larger sizes
- When in doubt, size up (resizing down is easier)
