Diamond Finder is a collector research tool for Pokémon cards and LEGO sets. Search live eBay listings, narrow results to exact cards or sets, separate auctions from Buy It Now, and research Pokémon cards in Collector Lab. It’s still being actively built, and I’m launching it here mainly to get honest feedback from collectors about what works, what doesn’t, and what would make the tool more useful
