Amorphous Diamond Treatment

Amorphous Diamond Treatment FAQs:

Will Asha®  test positive on a diamond tester?

No, it will not.  Even though the upper layer of Asha® contains a multitude of tiny diamond crystals (Amorphous diamond), they are linked together by SP2 bonds instead of SP3 as in gem diamond.  Thus, the heat signature is different and this is reflected when testing by a diamond tester.  

Note that diamond testers simply measure *heat conductivity*, they do not actually detect the presence of "SP3 carbon, or diamond".  Thus, traditional diamond testers are sometimes also fooled by colorless sapphire and Moissanite.   

However, if you are buying Moissanite solely because you believe it will test positive on a diamond tester, this should keep you on your toes:

How hard is the latest version of Asha®?

The current version of Asha® is similar in hardness to sapphire, or 9.0 on the Mohs scale.  
Diamond - 10
Moissanite - 9.25 (approx)
Asha®:  9.00 (approx)
Sapphire (corundrum) - 9.0
New generation zirconium simulants:  8.5-8.7 (approx)
Typical CZ - 8.0
Emerald - 7.5
Tanzanite - 7.0

Under the durability testing (abrasion via grinding wheel) it was a no-contest win for the latest version of Asha® as compared to any other type of zirconium based simulant. 

Will the amorphous diamond coating on the Asha® come off?

Atomic force microscope testing has shown the amorphous  diamond is literally blasted into the upper layers of the substrate, making it more like an infusion process and less of an actual coating or layering. Amorphous diamond also has a much more flexible molecular structure than crystalline diamond, which greatly impedes chipping.
