Proof, explained
Watch moissanite enter the DIA range.
Thermal diamond testers measure how quickly a stone transfers heat. Moissanite can conduct heat quickly enough to enter the diamond range on many common thermal testers.
- Refractive index of approximately 2.65-2.69
- Approximately 9.25 on the Mohs hardness scale
- Animated response applies to Moissanite selections
- A thermal result alone is not complete gemstone identification
Ready for demonstration
This demonstration applies to the Moissanite option.
Measured Differences
Moissanite vs. mined diamond.
Compare measurable gemological properties without treating one material as the other.
| Property | Moissanite | Mined diamond |
|---|---|---|
| Composition | Lab-created silicon carbide (SiC) | Carbon |
| Mohs hardness | About 9.25 | 10 |
| Refractive index | About 2.65-2.69 | About 2.42 |
| Fire | Higher spectral dispersion | More restrained dispersion |
| Origin | Lab created | Earth mined |
| Tester behavior | May register on many thermal diamond testers | Registers on diamond-specific testing |
A handheld thermal tester alone is not a complete gemstone identification method. Professional instruments and product-specific documentation provide more reliable verification.

Before You Ask
Questions, answered straight.
Where will 18 Inch 925 Sterling Silver Brushed Satin Finish Eternity Pave Setting 4-Prong Moissanite Necklace sit?
Use the interactive length guide to compare the lengths offered for this product. As a starting range, the guide matches each length to a neck circumference 2 to 4 inches shorter than the chain. Shoulder width, chain width and pendant drop can move the final resting point.
How should I measure a necklace I already own?
Open the necklace, lay it straight without stretching it and measure from one end to the other, including the clasp. Measure a pendant drop separately from the listed chain length.
What is the most versatile necklace length?
For many adults, 18 inches sits near the collarbone and works as a versatile starting point. Tennis necklaces often sit higher, while heavier statement chains may be preferred slightly lower.
What if I am between two chain lengths?
Choose based on the intended placement and layering plan. Size up for a lower, more relaxed line, or choose the shorter length to frame the neck and collarbone more closely.
