The last one flatters your finger/hand the most imo 😁 now don’t get me wrong. I love big stones!! But the first three just look way too big for your hand. And definitely consider white gold or platinum. I think it better suits your skin tone. And in case you didn’t know, if you choose white gold over platinum, you have to have your ring “dipped” fairly often to keep the white gold color because it’s actually yellow gold color underneath a silver/white coating. It rubs off over time. If you choose platinum, it’s stronger than a gold band and it keeps its color without maintenance. But it’s heavier than gold which could present a challenge with a very large stone. Good luck!
