Nugget said:Very nice, it might be worth doing a scratch test to confirm but I'd be very surprised if it wasn't a Sapphire.
Walnliz said:Scratch test mate. Hardness scale: Diamond 10...Sapphire 9....Topaz 8....Quartz 7 same as glass.
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. wink
Cheers Wal.
