We always meet the building labeled “MOST times here” in the photo below. Bonus: The “sometimes here” is much easier to find and also hosts the lapidary lab upstairs.

As of November 2024: Due to continuous A/C problem in the ʻadmin buildingʻ, we relocated all of 2022, 2023 and 2024 to the first floor of the lapidary building (DH or across from admin, the ʻMOST times hereʻ on the photo).
Rock & Mineral Society of Hawai‘i Meetings
Established in 1970, the Rock & Mineral Society of Hawaiʻi, Inc. is a non-profit, educational organization dedicated to mineral and rock collecting and appreciation and the lapidary arts.
- We meet on the 4th Wednesday of each month in the Makiki Distict Park in Honolulu.
We welcome anybody interested in minerals and gem stones and hope you can join us at one of our club meetings to meet kindred spirits and talk story about ‘rocks’.
If you have made it this far, and found us on the web – Congratulations!
Rock and Mineral Society of Hawaii: Monthly Meetings
Easy part first: We meet in the “most times here” on the 4th Wednesday of each month from 6:15 – 8:00 pm at Makiki District Park in Honolulu (except for adjusted dates in November and December).
We hold the ‘club business’ part of the meeting first, followed by an educational part. We discuss the mineral of the month and members bring examples from their collection for “show and tell”. Occasionally we have a guest speaker or a slide or video presentation. The meeting ends with ‘talk story’ until we need to vacate the room around 8 PM.
Please check our Facebook Page for current updates and the meeting topic of the month. Club members get a reminder email and newsletter with the mineral of the month.
Now the real ‘tricky’ part:
All buildings at the Makiki District Park have the same street address of ‘1527 Keeaumoku St’ (This might be a walk in the park for people born and raised in Makiki, but sure makes it hard for ʻoutsidersʻ.)
Parking
Please enter the parking lot from Ke‘e’aumoku Street. Parking is free but limited, due to the frequented tennis courts, pool and skateboard facilities in the park, the lot might fill up fast.
There is often parking available on the other side of the park next to the community gardens, if you know the area. Street parking along Ke‘e‘aumoku Street may be your best option, if you come right after 5:30 PM when it becomes legal and you are brave enough to park in rush hour traffic.
If you park in the (ewa) parking lot next to the tennis court walk mauka towards the buildings in the park (see map below). Take the walkway between the first two buildings and you see a smaller building in the to the right (DH).

Yes, that’s why we called it ‘tricky’. We met since 2024 in the same building as he lapidary lab, labeled “sometimes here” in the photo.
Please note that if a month happens to have 5 Wednesdays we do not meet at the ‘last’ but still the 4th of that month.
Lapidary Classes More
Lapidary classes are normally held on Thursday evenings from 6:00-8:00 pm (clean up at 7:45 p.m) and are open to all Rock & Mineral Society of Hawai’i members. Please attend a meeting to find out more and if the classes are being held (and how to find it).
Lapidary for Non-members: The City and County of Honolulu, Parks and Recreation, offers a lapidary class for adults at Makiki District Park, three times a year: Spring, Summer, and Fall. Interested people need to sign up for this course with the C&C Parks and Recreation or directly with Makiki District Park. Please don’t you “just show up“, since there is no guarantee that an instructor might be available to teach you. You are not covered by insurance is you did not sign up with Parks and Rec and we can not allow you to use the equipment. More
Our 18th Annual Hawaii Rock and Mineral Show Oct 19 & 20, 2019 was cancelled. Details click here. In January 2020 we had voted and decided on the dates for our first three 2020 Gem and Mineral Shows in Hawaii… Little did we know back then…
