Caveman Rocks: Quality Minerals: Fair Prices.

Caveman Rocks started in 2012. The owner, Dave Leppert, is a professional geologist in Boise, Idaho and has been collecting minerals for over 30 years. The name simply comes from the fact that my wife calls me the "Caveman". Caveman Rocks is the transition from my mineral collecting hobby to a business, to share my enjoyment of minerals with others, and to grow my personal collection while providing minerals to the public at reasonable prices. I mostly collect mineral specimens, though occasionally will pick up agates, petrified wood, and other materials of geologic interest. There will eventually be a section with jewelry and I also purchase cut gems and other items which will be posted on the site, though initially I will focus on minerals.

Another facet of Caveman Rocks is to provide information on the geology of southwest Idaho. As a part time ski instructor at Bogus Basin, I enjoy pointing out various aspects of the local geography and geology to my students and it makes their experience on the mountain more meaningful. There is a display I made on the 3rd Floor of the JR Simplot Lodge that shows various aspects of the local geography and geology.

I travel as part of my work as a consulting geologist and sometimes can acquire minerals from unusual localities. I also have collected at a variety of localities throughout the western US, many that you rarely see material from on the market.

At times I may be out of town and not able to fulfill orders immediately. I normally will have email access and will respond promptly to any inquiries even if not able to ship anything and can put things on hold for you. If you don't hear back from me within 24 hours, it probably means I don't have internet access.

Only a relatively small portion of my inventory is shown on the website. If there is something you are particularly interested in, let me know. I may have other pieces available.

Mineral Photos:
I take my mineral photos using a Nikon D3200. Though I have used digital cameras for many years, and film SLRs for many years prior to that, this is my first digital SLR and I still have a lot to learn about using it.

Photo lighting is primarily with LED strip lights, the same lights I use in my mineral cabinets, which I purchase at I'm using the 24v ultrabright strip lights that have a color temperature of 6000 to 6500K, though some of my cabinets had been retrofitted with their 12 v strips. These are much brighter than most of the LED strip lights I've seen elsewhere. has a good selection of accessories and mounting hardware.

Some minerals may be backlit, which will be noted, but most are taken with the lights directly overhead. In some photos you will see the reflection of the lights. Some have too much glare, I obviously need more practice taking mineral photos.
E-Mailing List:
If you wish to be added to my email list, simply contact me at I will not flood you with emails, but will send periodic notices when new material is posted, etc. Contact me at: OR
The geoleppert is my primary email which I generally check several times per day and I usually try to check the other at least once per day.

Website Updates:
I will try to add new pages on a regular basis. I will add the links to them at the bottom of this page, and elsewhere on the site as appropriate. My original design only had 8 pages and as I progress with this, I'm figuring out better ways to organize it. I will try to update the site every 2 months or so depending how busy I am with other jobs.
