by paperunicorn » Jan 6, 2019 Hi friends! I've decided that I'd like to start saving for a ruby or an emerald and have been doing some research. Obviously a ruby is probably going to be more expensive due to rarity, but in my searching I've found so few unheated rubies, with such a huge price difference between them and the heated gems, that I'm hoping to get some thoughts from PSers with more gemstone experience than I. Could you share your thoughts about completely natural vs. heat treated gemstones? Thank you in advance.
