  1. She said yes 👍
  2. Having the ring tell a story was the key to making this work. Without a story it’s impossible to make decisions.
  3. Finding an incredible designer was the key. I actually hired two designers. One on Fiverr and one Upwork. The Upwork designer blew everyone out of the water and make this whole project possible.
  1. Get your ring measurements right! I measured a ring she wore on her middle finger instead of one she wears on her ring finger so the engagement ring fits the wrong finger 🤦‍♀️
  2. Materials. I’m super happy with my material choices and was very picky about them, but they did make the project take much, much longer than necessary not to mention the extra cost of needing to hire a project manager.
