Pourquoi cela vaut le détour
Washing gravel and then deciding which rough stones are worth heat treating and cutting is the first real judgement call in the chain from deposit to gemstone.
Avant de partir
The site states that all equipment is provided at no additional charge and that rough sapphires are weighed and bagged free of charge, with a separate fee for gem-quality evaluation. Mine visits are first come, first served with a VIP section available for groups; there is no mobile signal at the mine, the wash trough is outdoors with little cover, and visitors are advised to bring a chair and shade if they need them.
