Our museums remain closed due to COVID-19. While LA County Public Health has entered Phase 3 of the Roadmap to Recovery, allowing for the reopening of museums on June 12, our museums are still slowly welcoming back staff and are in the process of planning for new health and safety protocols in our galleries and gardens. Therefore, we will not be reopening until later in the summer. Sign up here to be the first to know when we will safely re-open to the public and in the meantime, stay connected from home.

Motivated by their passion for mineral sciences, the Gem and Mineral Council is a group of museum supporters who work with curator Dr. Aaron Celestian to help us continue groundbreaking mineralogy research, while enjoying special content and behind-the-scenes access to some of our most exciting work.

Your support helps us

  • Grow our gem and mineral collection to keep it at a world-class level, securing minerals for research and education and fascinating specimens for the Gem and Mineral Hall
  • Launch groundbreaking rotating exhibitions and develop our existing (and fabulous) Gem and Mineral Hall
  • Create fun educational programs around gems, minerals and meteorites—sharing our treasures and knowledge by increasing our online outreach
  • Support our innovative research: help the discovery of new minerals, the investigation of the deep earth using exciting clues from diamonds or fund the next generation of scientists.
