Why Do Our Moissanite Watches Pass the Diamond Tester?
Many people wonder how a stone that costs a fraction of a natural diamond can still “trip” a professional diamond tester. The answer lies in Thermal Conductivity.
Most industry-standard diamond testers (like the Presidium) work by measuring how heat travels through a gemstone. Because Moissanite is a “double refractive” stone with thermal properties nearly identical to a natural diamond, it transfers heat in the exact same way.
At IcedJewelz, we take this a step further:
- VVS1+ Selection: We only use stones with the highest clarity grades, ensuring no internal inclusions interfere with the tester’s sensors.
- D-Color Rating: By using colorless stones, we ensure the light and heat return is consistent with premium natural diamonds.
- Precision Cutting: Each stone is hand-cut to specific proportions that mimic the “hearts and arrows” of a diamond, ensuring that the tester makes perfect contact with the stone’s surface every time.
When you wear an IcedJewelz piece, you aren’t just wearing “simulated” jewelry—you are wearing a gemstone that is physically and chemically close enough to a diamond to pass the ultimate test.
