Glass and quartz will both scratch each other. Glass won't scratch Topaz. Topaz won't scratch Sapphire. Sapphire won't scratch diamond. Try scratching it with glass or quartz first.
Can send you up a couple of each to use as scratch testers if you like.
Cheers Wal.

Thanks Wal, if you could spare a couple of low graders that would be great.
P.S. I haven't forgotten about that Gem book, I'll send it back sometime this week. Thanks again for letting me borrow it.
