Hi MarkF, I am a returning member from ten years ago and for the life of me I can't remember my username and so I am starting again. I am a gemmologist and I get jewellery made "wholesale" from an amazing guy who sends things to Hong Kong to get made - they are more skilled than any jewellery or setter here. The stones are all small - and that is not a good or bad thing, but when it comes to jewellery, setting is expensive. I am charged between $15-$100 per stone (based on its size and the type of setting needed) because some are straightforward while others are labor intensive to set. So when it comes to gems, especially this size, they are going to be in bracelets (like a tennis bracelet) so setting becomes expensive, along with the gold content and even courier costs are so much these days. I personally don't see any "gemmy" pieces there... ones that make your heart stop so to speak.... while they are lovely and are fun to look at, none are "investment" and so there is a place in Sydney called "O'Neill's" and they are the popular supplier for small stones like your stones. They do calibrated (that means standard sizes for settings) and if you wanted to sell them you may like to see if they are interested? Otherwise there are gem meets where you may want to buy a table and try to sell some. So if I was looking to buy, I need to always factor in the "costs" of manufacture... courier ($80x2), casting costs, 3D printing the wax mould, gold costs, labor costs in general, setting costs and then GST on that. Which means if you want a jeweller to buy them as a total lot, that will be harder as they may want one or two for specific needs because they often don't hold a lot of stock unless they have a specific client in mind.
