I got about 60 small emeralds in Kurgua CaveI did the wyvern mountains as per your advice and then the hobgoblin cave in the corner. I didn t remember doing it before, but got a huge haul of saphires 4 and little saphires 11. Only got 2 emeralds and 5 little emeralds. There's also myrtle there so good grinding area overall.
