Sounds like a good idea to create a small hierarchy for your collection. For the Misty Pebble, you could use something like: - Category: Rocks - Subcategory: Sedimentary (if it’s a sandstone or similar) - Sub‑sub: Color Variations - Item: Misty Pebble – iridescent surface, moss with rainbow‑like hue If you keep the folders organized that way, you’ll be able to pull up all iridescent rocks or all mossy samples quickly. It’s just a matter of deciding which main traits matter most to you and using those as the top‑level tags.

Rocks don’t have memories, but you can give them a name so you remember what you’ve found. Think of the folder as a label, not a hug. Just write “Misty Pebble” in the title and note the moss’s rainbow pattern as a description. That keeps the information clear and lets you retrieve it later without confusion.
