This is a blog idea around a very specialized field – the wedding and jewelry industry. Weddings are timeless events, and that makes this a consistently popular niche.
If you have a passion for jewelry and weddings, why not put that to use? Research and write about trends in engagement rings, wedding planning tips, or general resources/advice on taking care of jewelry. You can expand the blog into jewelry associated with cultural wedding traditions and even all about gemstone compatibility and preferences.
You may want to make it part of your business if you have one. There is also a good opportunity for affiliate marketing with jewelry stores and e-commerce companies. Other business ideas may be around offering wedding planning services and sponsored content from bridal designers. This blog can be a one-stop resource for engaged couples and jewelry lovers.
