Will the Asha simulated diamond scratch glass?
Yes, the Asha diamond simulant will readily scratch glass.
While other sim makers tout the ability to scratch glass as something impressive, it is not. Glass is quite soft at 6.0Mohs, so virtually any diamond simulant will scratch glass.
The reason the 'glass scratch' test was ever given any import was that many years ago, the most common diamond simulant 'was glass'....hence it was a valid test..in the 1800s.
Nowadays, any established diamond simulant will scratch glass and we therefore don't recommend that this test be even a concern when shopping for imitation diamonds.
