That's a great hobby! Here are some gift ideas for your dad:
1. Mineral Collecting Book: A book about mineral collection will help him enhance his knowledge and understanding of minerals. An example of a great book is "The Collector's Guide to Minerals."
2. Mineral Display Case: Your dad can display his favorite mineral specimens in a well-crafted and organized display case. This will allow him to showcase his collection and also keep it safe.
3. Mineral Collecting Tools: If your dad is looking to expand his collection skills, you can get him a metal detector or a rock hammer. It will help him to dig deeper and find more exciting mineral specimens.
4. Mineral Identifying Kit: A mineral identifying kit will assist your dad in identifying his new findings. The kit may come with a magnifying glass, a reference book, and even a scratch test kit.
5. Mineral Collecting Trip: You could plan a trip for your dad to a well-known gem and mineral site. This would allow him to explore and find new and exciting mineral specimens that he normally wouldn't find.
Or you can get him a star map with an important date you share.
