This Sprawling Texas Rock Shop Is Stacked Floor to Ceiling With Fossils, Crystals and Giant Geodes

I have never once left a rock shop with only the one thing I went in for. Somebody hands you a chunk of amethyst, you feel the weight of it, and suddenly your windowsill needs six. That is a personality flaw, and I have made peace with it.

Which is exactly why Nature’s Treasures in Austin is dangerous. This is the largest metaphysical rock shop in the country by its own count, and the showroom is glittering, crowded, cool-stone aisles stacked floor to ceiling with crystals, fossils and geodes big enough to climb into.

Below, I will walk you through the giant geodes, the ancient fossils, the outdoor rock yard, the story of the woman who built it all from one shelf, and everything you need to plan a visit.

The Geode You Can Sit Inside

Start with the reason people drive in from three counties away. Near the front of the showroom sits a hollowed amethyst geode from Brazil that the shop calls the largest sit-in amethyst geode in the United States. Two or three grown adults can fit inside it at once.

It is technically a smoky amethyst, a deep purple shot through with bands of milky white calcite. Those calcite pockets are smoother than the crystal points, which is the reason you can actually sit in it without regretting your choices.

The shop has used it as a mascot for years. Owner Karen Richards was photographed inside it for a billboard along Interstate 35 with two words underneath: “We Rock!” If you ever drove that stretch and wondered where the purple cave went, this is the answer.

And yes, it is for sale. The price tag on the big pieces runs to six figures. The shop says its inventory ranges from 25-cent tumbled stones all the way up to a $125,000 amethyst, so the geode sits at the very top of that ladder.

That one is the showpiece, but geodes are everywhere here. Cathedral geodes taller than a toddler stand along the walls like purple doorways. Smaller ones are split into pairs so you can see the crystal lining on both halves. Some are cut into hearts, some into bookends.

Pro tip: bring a tape measure if you are shopping for a big one. People fall in love with a cathedral geode and then discover it will not fit through the front door at home.

Fossils From a Sea That Dried Up Long Ago

The fossil cases are my favorite corner, and I say that as someone who came for the sparkle. The shop stocks sea creatures it dates at around 350 million years old, which means they were swimming long before there were dinosaurs to step on them.

You will find ammonites, the coiled shells that look like a ram’s horn cut in half and polished until the chambers show. There are trilobites, the little armored bugs that scuttled across ancient sea floors.

Slabs and plates of other ancient sea life turn up too, and the mix changes with what the buyers bring back. I could spend an hour at these cases alone, reading the little cards and trying to picture the ocean that used to be here.

What makes the fossil section fun is the price spread. It runs from small starter pieces a kid can afford up to museum-grade specimens on display stands. Both are real, and both come with staff who will happily tell you what you are holding.

Did you know? Central Texas itself was underwater for much of that ancient history, which is why Hill Country creek beds are full of fossil shells. The shop is a good place to learn what you have been picking up on hikes for years.

Crystals, Crystals, and Then More Crystals

The retail showroom is the heart of the place, and the shop puts it at roughly 15,000 square feet. Picture bins of tumbled stones sorted by color, walls of quartz points, trays of rings and pendants, and singing bowls lined up by size.

Amethyst, citrine, rose quartz and turquoise are the crowd pleasers. Then you get into the stranger stuff: moldavite, that green glassy stone that people swear was born from a meteorite strike, or selenite towers that glow when a lamp is behind them.

Carvings fill whole shelves. Animals, skulls, hearts, eggs, spheres and pyramids, all cut from stone. Salt lamps throw an orange glow across one section. Nearby you will find tarot decks, candles, incense and a wall of books.

The singing bowls deserve a stop of their own. Run the mallet around the rim of a quartz bowl and the whole aisle hums. Staff will show you how, and nobody minds if you try three sizes before picking one.

One Yelp reviewer summed up the effect of walking in better than I could: “never have I seen so many gems under one roof.”

The shop also gives space to independent vendors, with dozens of booths selling their own crystal art, jewelry and gifts. So the mix changes from visit to visit, which is the shop’s excuse and mine for going back.

Lights Off in the Observatory

One room is worth hunting for. The shop calls it the Rockstar Observatory, and it is a darkened space where fluorescent minerals sit under black light. Rocks that look dull gray under normal light turn electric green, orange and pink in there.

I love this kind of thing because it is science pretending to be a magic trick. Certain minerals absorb ultraviolet light and throw it back at a wavelength your eyes can see. Fluorite, calcite and willemite are the classic performers.

Kids tend to lose their minds in this room, in the good way. It is a nice reset between the crowded aisles, and a good excuse to let your eyes adjust before heading back out to the bins.

Out Back in the Rock Yard

Step outside and the mood changes from jewelry store to quarry. The Rock Yard is exactly what it sounds like: mounds of rough, unpolished rock heaped along a path, most of it sold by the pound.

This is where the bargains hide. That same reviewer picked up a rose quartz piece out here for three dollars. Bins of raw agate, jasper, quartz and petrified wood sit next to boulders and big decorator slabs meant for gardens and entryways.

I would budget real time for the yard. It is the kind of place where you go in for a doorstop and come out with a plan for a rock garden.

The path leads to the Rock Depot at the southeast end of the big building. This is the lapidary shop, the department for people who cut and polish their own stone. It sells rough and polished material, tools and jewelry-making supplies, and it runs cutting, drilling and polishing services.

The prices are posted plainly. Drilling starts at $9 for a simple job. Cutting is $1.65 per inch around the piece. A cabochon, a polished dome shape for jewelry, runs about $43. Expect roughly two weeks on any order, so drop it off before a trip rather than after.

From One Shelf to the Biggest in the Country

The story behind all this starts with a single shelf. Founder and owner Karen Richards, a California native, got hooked on minerals in the early 1980s while living in San Diego. She moved to Austin for good in 1989.

The way the shop tells it, she had been using amethyst clusters to dress up the displays at her furniture store. Customers kept trying to buy the rocks instead of the sofas. One shelf of crystals became a room, and in 2000 Nature’s Treasures opened on East Fifth Street.

By 2005 there were three small stores. Around 2011 Richards pulled them together into one 14,000-square-foot building at 4103 North Interstate 35. The showroom, the Rock Yard, the Rock Depot and an event center all shared one lot. That was the home most Austinites remember.

Then the highway came for it. The I-35 expansion through central Austin claimed the property, and in 2025, the shop’s 25th year, Nature’s Treasures moved a few miles north to a bigger campus near the Braker exit. The City of Austin has even declared August 8 “Nature’s Treasures Day.”

Richards has said the idea was born on a back porch in Phoenix in 1987, in a conversation with her mother. In her own words, she wanted “to blend my love of rocks and this new metaphysical energy and have the largest metaphysical and rock store in the United States.”

Retail manager Michael Kallstrom put the growth more simply. “We started with just one shelf with a few crystals,” he told Community Impact in early 2025. Twenty-five years later, the shelf is a campus.

Classes, Readings and Full Moon Nights

The new campus includes a 5,000-square-foot Community Event Center, and the calendar stays busy. Think crystal workshops, sound baths with those singing bowls, author talks, plant swaps and full moon gatherings.

Practitioners work in the store daily. Depending on the day you might find tarot readers, astrologers, reiki sessions or an aura photographer set up near the back. The event center also hosts a monthly metaphysical fair and jewelry bazaars a couple of times a year.

None of it is required. Plenty of people come purely for the rocks and never look at a tarot card. But if you are curious, this is a low-pressure place to try something new.

Tips Before You Go

Give yourself at least an hour. Between the showroom, the observatory, the yard and the depot, there are really four stops here, and the reviewer who warned that you will be “entrapped for at least an hour” was not exaggerating.

Bring a small bag or a box with towels if you plan to buy anything heavy from the yard. Rough rock scratches car upholstery, and a fifteen-pound slab of agate does not want to ride loose in a trunk.

Doors close ten minutes before the posted closing time, so arrive with room to spare. And go on a weekday if you can. Weekends bring families, and the geode gets busy.

Pro tip: the tumbled-stone bins are the cheapest way to leave happy. Pick a handful by color for a few dollars each, and ask a staff member what each one is. They know.
