Gold is the official state mineral of California. That fact shows up on classroom posters and trivia cards, but the citation is often missing. This page gives you the exact statute, the year it was enacted, and the context around it. Every fact below traces back to a primary or institutional source.

We keep it short and dense on purpose. If you need one page that names the law, the year, the museum, and the specimen, this is that page.

The 1965 statute, in its own words

California Government Code Section 425.1 is one sentence long. It reads: "Native gold is the official State Mineral and mineralogic emblem." The section was added by the Statutes of 1965, Chapter 89. That is the citation you want on a school worksheet, a museum label, or a wikipedia footnote.

Section 425.1 sits inside Title 1 of the Government Code, Division 2 on the state seal, flag, and emblems, Chapter 2 on the state flag and emblems. The California Legislature enacted the surrounding chapter in 1943 and has extended it over the decades. Gold and serpentine were the two mineral additions in 1965.

The word "native" in the statute matters. Native gold means gold as it occurs in nature: dust, flakes, nuggets, or crystalline specimens, without being combined into a compound. It is the metal in the form miners actually pulled out of Sierra streambeds and quartz veins.

Why gold, and why 1965

Gold and California are inseparable. The January 24, 1848 discovery at Sutter's Mill in Coloma triggered the California Gold Rush. About 300,000 migrants reached the state by 1855, and California entered the Union as the 31st state on September 9, 1850, admitted as a free state under the Compromise of 1850. Gold, in short, is the reason modern California exists as it does.

By the mid 1960s, the Legislature was formalizing state symbols across categories that had been informal for decades. The California state flower (golden poppy, 1903) and state animal (California grizzly, 1953) were already law. In 1965, lawmakers added the two geologic emblems: gold as state mineral (Section 425.1) and serpentine as state rock (Section 425.2), both in the same bill.

Native gold made the short list because it was the mineral most tied to California's origin story and economy. It is also still produced in the state on a small scale, mostly from historic districts along the Mother Lode.

The same bill made serpentine the state rock

People often assume the state mineral and the state rock come from different eras. They came from the same 1965 bill. Government Code Section 425.2 reads: "Serpentine is the official State Rock and lithologic emblem." It was added by Statutes of 1965, Chapter 89, the same chapter that added the gold statute one section earlier.

The pairing was deliberate. Gold represented the mineral wealth. Serpentine represented the geologic ground it came out of. Serpentine belts run for hundreds of miles along the Coast Ranges and the western Sierra Nevada foothills, and they are commonly found near gold-bearing quartz veins. Together, gold and serpentine encode both the treasure and the terrain.

Serpentine is not one mineral but a rock made of minerals in the serpentine subgroup. It is typically greenish, slick, and sometimes veined with white. You can see it along Interstate 280 south of San Francisco, throughout the New Almaden district, and in outcrops across the Klamath and Sierra ranges.

The other geologic and natural symbols of California

The state mineral and state rock are two of a broader set of official California emblems in the Government Code. Reading the section list gives you the full picture in one glance.

Section 425.3 designates benitoite as the official state gemstone. Benitoite is a rare blue mineral first identified in San Benito County, from which it takes its name. The state has never had a substantial commercial deposit anywhere else.

Section 425.5 designates the California gray whale (Eschrichtius robustus) as the official state marine mammal. Section 425.7(a) designates Augustynolophus morrisi, a duck-billed dinosaur, as the official state dinosaur. Section 425.7(b) designates the saber-toothed cat (Smilodon californicus) as the official state fossil. Section 425.8 designates the Chipped Stone Bear, a bear-shaped Native Californian eccentric artifact, as the official state prehistoric artifact.

Together these entries form a bench of California natural-history emblems. Gold sits at the top of that bench because it was, in every sense, the reason the state existed by the time the Legislature codified the list.

Where the official state mineral collection lives

California maintains an official state mineral collection. It sits at the California State Mining and Mineral Museum, on the Mariposa County Fairgrounds south of the town of Mariposa. California State Parks operates the museum.

The collection began in 1880, when the state's first mineralogist compiled specimens for public display in San Francisco. It grew across the late 19th and 20th centuries into a working mineralogic record of the state. The collection moved to Mariposa and became a state park in 1999. It contains over 13,000 objects, including mining artifacts, gem specimens, and rare crystallized gold from California's historic districts.

If you want to see the state mineral in specimen form, this is the place to go. The museum is not the only mineral collection in the state, but it is the one holding the official collection recognized by California State Parks.

The Fricot Nugget: the crystalline centerpiece

The centerpiece of the museum's crystalline gold collection is the Fricot Nugget. It is a 13.8-pound specimen of crystallized gold found on the American River in 1864. California State Parks describes it as "the largest remaining intact mass of crystalline gold from 19th century California".

Crystalline gold specimens like the Fricot are rare because most 19th century gold was melted down for coin and jewelry, or sent to the mint. The Fricot survived because it was purchased and preserved by Jules Fricot, a Placer County mine owner, and eventually donated for public display. That is why the specimen carries his name today.

The Fricot is not the biggest California nugget ever recorded. Larger masses of gold were found, weighed, and then melted or sold off. What the Fricot has is preservation. It is the largest crystalline California gold specimen that still exists in intact form and is on public view.

The 2010 attempt to remove serpentine

Serpentine has one wrinkle in its record. In February 2009, State Senator Gloria Romero introduced Senate Bill 624 in the California Legislature. The bill sought to repeal Section 425.2 and remove serpentine as the official state rock.

The bill's stated reason: serpentine can contain chrysotile asbestos, and asbestos exposure raises the risk of mesothelioma. The findings section of the bill argued that the state should not designate as its official rock a material whose fibers can be a health hazard when disturbed and inhaled. The Senate passed the bill. In the Assembly, it stalled. On November 30, 2010, the bill "died" in the Assembly Rules Committee without further action, according to the official legislative history at leginfo.legislature.ca.gov.

The practical effect: Section 425.2 remains in force. Serpentine is still California's state rock. The 2010 debate did raise public awareness that outcrops of serpentine can contain asbestos minerals, which is a genuine geologic fact worth teaching alongside the emblem itself.

Table: California's geologic and natural emblems

A compact reference to the California Government Code sections for the state mineral, state rock, and the immediately adjacent natural-history emblems. All are inside Government Code Chapter 2 on the state flag and emblems.

The visual makes the pattern easy to see. Gold and serpentine were the first two geologic emblems on the list, in the same 1965 bill. Every other natural-history emblem was added later, one section at a time, over the following half century.

When this reference will not help you

This page is a civics and heritage reference. It is not a prospecting guide. If you want to know where you can legally pan for gold today, or which claims are open on public land, that is a different question with different rules. Look at our companion guides on California panning rules and where you can pan legally.

It is also not a mineralogy textbook. If you need the crystal system, hardness, cleavage, and geologic formation environment of native gold or of the serpentine subgroup, consult the California Geological Survey and standard mineralogy references. Government Code Section 425.1 tells you the emblem, not the science.

And it is not investment guidance. Owning California-mined gold, buying gold coins, or holding gold in a retirement account are separate topics with separate rules. If you get interested in that side of the story after reading the history, our editorial coverage of gold ownership in California is one door in.

People also ask

What year did California make gold the official state mineral?
1965. The California Legislature added Government Code Section 425.1 as part of Chapter 89, Statutes of 1965. The statute reads: "Native gold is the official State Mineral and mineralogic emblem." Source: California Legislative Information.

What is the exact statute that names gold the state mineral?
California Government Code Section 425.1. It sits inside Title 1, Division 2, Chapter 2 of the code, alongside the state flag and other emblems. The section is a single sentence.

Is serpentine really California's state rock?
Yes. Government Code Section 425.2 reads: "Serpentine is the official State Rock and lithologic emblem." It was added in the same 1965 bill that named gold the state mineral. Senate Bill 624 in 2010 tried to repeal it. That bill died on November 30, 2010, so serpentine remains California's state rock.

Where is California's official state mineral collection kept?
The California State Mining and Mineral Museum in Mariposa. The collection began in 1880 and holds over 13,000 objects. It moved to Mariposa and became a state park in 1999. Its centerpiece is the 13.8-pound Fricot Nugget from the American River, found in 1864. Source: California State Parks.

Why gold and not another mineral or metal?
Gold is inseparable from the state's origin. The 1848 discovery at Sutter's Mill triggered the Gold Rush, brought about 300,000 migrants by 1855, and pushed California to statehood in 1850. When the Legislature codified state emblems in 1965, gold was the mineral most closely tied to California's identity, economy, and geology.

Does California have a state gemstone or a state fossil too?
Yes. Section 425.3 names benitoite the official state gemstone. Section 425.5 names the California gray whale the state marine mammal. Section 425.7 names Augustynolophus morrisi the state dinosaur and the saber-toothed cat the state fossil. Section 425.8 names the Chipped Stone Bear the state prehistoric artifact.

Where was gold first found in California?
James W. Marshall found gold in the tailrace of Sutter's Mill on the South Fork of the American River in Coloma, El Dorado County, on January 24, 1848. The site is preserved today as Marshall Gold Discovery State Historic Park. Source: California State Parks.

Can I see actual gold from California's official state collection?
Yes, at the California State Mining and Mineral Museum on the Mariposa County Fairgrounds. The state's official collection is on public display, along with the Fricot Nugget and other crystalline gold specimens. Check current park hours and admission with California State Parks before you go.
