[QUOTE="Ditch, post: 313201, member: 9183"] Cheers goldierocks, definitely hexagonal in cross section (did a bit more research on crystal systems). As you suggested I used a piece of quartz crystal to scratch it but it didn't leave a mark. Just for the sake of practice I tried a piece of sapphire which did leave powder behind. Also tried a piece of garnet (6-7.5) with no result. Thanks for the tips on simple things to test hardness & I will keep an eye out for some broken porcelain plates to use as streak plates. New to gem & mineral fossicking, mainly concentrated on gold in the past, looking forward to learning more about it! [/QUOTE]
