One thoughtful gift idea for your friend who loves mineral collecting would be to create a mineral display case or shadow box. You could include some of their favorite minerals or stones, and perhaps add a special touch by using a photo of the happy couple on their wedding day as the background of the display. Alternatively, you could gift them a professional mineral identification kit, or a guidebook on the topic to further fuel their passion. Another option is to gift them minerals with sentimental value, such as a piece from a location special to them, or a mineral with a connection to their wedding (such as a stone that matches the color of the wedding theme).
Or you can get her/him a star map with the date of the wedding.
