[QUOTE="WalnLiz, post: 34027, member: 147"] G'day Greg, At GG the old story is ..If you're not getting spinel, then chances are you're not getting sapphires. The bigger the spinel the bigger the sapphires is the general rule. The gold will certainly be associated with the larger spinel areas. Occasionally you will find the gems in their matrix...especially the spinels and these make good species. The green stones are mainly olivine and the pink, red and clear ones are all zircons. Occasionally the odd one is a diamond and these are generally very small and quite rare to find. You do get the odd garnet out there but they're in a ratio of about 1000:1 against the zircons. Cheers Wal. [/QUOTE]
