I apologize for any formatting issues, I am on mobile and have also never posted on Reddit before. I am planning on purchasing a small diamond necklace for myself and I am hoping for some advice. This will be the most money I have spent on jewelry and I want to make the right choice. I am hoping to not spend much more than $300. I prefer yellow gold and am looking for a small diamond necklace appropriate for everyday wear. Sustainability and ethical sourcing are also important to me.
