California has always been known for its incredible natural riches. Our mountains hide gold, our deserts conceal rare gems, and our museums showcase some of the most spectacular minerals on Earth. But where there are treasures, there are also those willing to steal them.
You might think bank robberies or art thefts get all the attention. Think again. California has a wild history of daring heists targeting everything from massive gold nuggets to priceless gemstones.
Some of these thieves were clever masterminds who planned for months. Others were opportunists who grabbed whatever sparkled and ran. Their stories are as fascinating as the treasures they stole.
From the legendary gold rush days to modern museum break-ins, these crimes have shaped our state’s history. The stolen items themselves tell amazing stories about California’s natural wealth and why people risk everything to possess it.
Let’s dig into the dirt-covered truth about the greatest rock, mineral, gem, and gold heists ever pulled off on California soil. These stories might sound like Hollywood movies, but they really happened in our state.
The Greatest Rock, Mineral, Gem, and Gold Heists In California
Here are the most notorious mineral and gemstone thefts our state has ever seen. From small-town museums to world-famous collections, these crimes shocked communities across California:
The Bahia Emerald Caper – $1,000,000,000+
The Bahia Emerald, one of the world’s largest known emeralds, weighing approximately 840 pounds, has a history as complex and multifaceted as the gem itself.
Discovered in 2001 in the beryl mines of Bahia, Brazil, this massive stone comprises numerous emerald crystals embedded in a host rock, with individual crystals measuring up to several feet in length. It was transported to the United States, where it changed hands multiple times under circumstances that remain murky.
By September 2008, the Bahia Emerald was reported stolen from a secured vault in South El Monte, Los Angeles County, California. This theft sparked a convoluted legal battle over its rightful ownership. Multiple parties emerged, each claiming legitimate possession of the emerald.
The Los Angeles Sheriff’s Department eventually seized the gem from a gem dealer in Las Vegas, placing it under governmental custody as the courts deliberated its fate.
In December 2024, a significant development occurred when a U.S. federal court ruled in favor of repatriating the emerald to Brazil, recognizing it as a national treasure that had been illicitly mined and exported.
The value of the crime today
The Bahia Emerald, discovered in 2001, has been valued at approximately $400 million, though estimates vary, with some sources suggesting it could be worth up to $1 billion.
Brink’s Armored Truck Gem Heist – $100,000,000+
In July 2022, a significant theft occurred involving a Brink’s armored truck transporting jewels between California gem shows. The truck had stopped overnight at a rest area in Lebec, north of Los Angeles. During this stop, criminals breached its lock and stole 22 bags of jewelry and gems within minutes
Brink’s estimated the stolen items’ value at $8.7 million. However, the victimized jewelers claimed the worth was up to $100 million. This discrepancy led to disputes and lawsuits between Brink’s and the jewelers.
The heist involved dozens of rare diamonds, rubies, and antique pieces from 18 different jewelry dealers. The FBI continues to investigate this sensational heist, likened to an “Ocean’s Eleven” caper. Unfortunately, the theft forced several small jewelers out of business due to the substantial losses.
The value of the crime today
The stolen jewelry’s value is disputed, with estimates ranging from $8.7 million to $100 million.
The Great Diamond Hoax – $13,000,000+
In 1872, two Kentucky prospectors, Philip Arnold and John Slack, executed one of the most notorious frauds of the era. They “salted” a remote site in the Sierra Nevada mountains with uncut diamonds, rubies, sapphires, and other precious gems.
This deceptive act led investors to believe they had discovered a rich diamond mine. Prominent financiers and businessmen, including Charles Tiffany and General George McClellan, invested heavily in the scheme.
The fraud was eventually exposed when geologist Clarence King investigated the site and identified the planted gems. This revelation led to the collapse of the scheme, but not before investors had been swindled out of a substantial fortune.
The value of the crime today
The exact amount defrauded is unclear, but estimates suggest investors lost over $600,000 in 1872, equivalent to approximately $13 million today.
San Francisco Jewelry Center Robbery – $9,000,000+
On April 6, 2003, Lang Antique & Estate Jewelry, located in San Francisco’s Union Square, was the scene of a meticulously planned and executed heist. The operation began the night before when three men clandestinely tunneled through an adjacent wall to gain entry into the store.
Once inside, they expertly disabled the alarm system, ensuring that their presence remained undetected. The trio then concealed themselves within the premises, awaiting the arrival of employees the following morning.
As staff members began their workday, the robbers emerged, brandishing firearms, and took the employees hostage. Under duress, the staff was compelled to open the store’s safes, from which the thieves extracted an estimated $6 million worth of vintage jewelry.
The stolen items included an array of diamond rings, Art Deco bracelets, and brooches adorned with rare gemstones such as Burmese rubies and Kashmir sapphires.
Shortly after the robbery, George Turner, a childhood associate of the primary suspects, was arrested at a San Francisco beachfront motel. The investigation further revealed that brothers Dino and Troy Smith were the masterminds behind the operation.
Dino Smith was eventually captured outside a train station in Queens, New York, following a cross-country pursuit. However, Troy Smith remained at large for some time before being apprehended.
The value of the crime today
The $6 million stolen in 2003 is approximately equivalent to $9 million today.
San Francisco Mint Gold Heist – $4,500,000+
Over a span of ten months in 1856, the San Francisco Mint experienced a significant loss of gold, totaling $150,550. This disappearance raised alarms, leading to suspicions within the Mint’s administration.
Agoston Haraszthy, the Mint’s melter and refiner, was accused due to the gold vanishing from his department. Despite a rigorous four-year legal battle, Haraszthy was acquitted in 1861, as evidence of his involvement was lacking.
The case remained unresolved for over a century. In 1891, workers discovered a wooden box containing gold ingots and granules beneath a house in Oakland, California. This hoard amounted to approximately $143,000, nearly matching the stolen sum.
Further investigation revealed that the house’s previous owner, John Eckfeldt, a former Mint official, had purchased the property in 1871 and later committed suicide there. This discovery shed light on the long-standing mystery, suggesting Eckfeldt’s involvement in the heist.
The value of the crime today
The stolen $150,550 in 1856 would be worth approximately $4.5 million today, considering gold’s current value.
Hollywood “Bling Ring” Burglaries – $4,000,000+
Between October 2008 and August 2009, a group of teenagers and young adults from Calabasas, infamously known as the “Bling Ring,” embarked on a series of burglaries targeting the homes of Hollywood celebrities.
The group, comprising individuals such as Rachel Lee, Nick Prugo, Alexis Neiers, Diana Tamayo, and Courtney Ames, exploited the allure of celebrity culture and the accessibility of personal information online to execute their crimes.
Paris Hilton was among their primary targets, with her residence burglarized multiple times. Initially, the group pilfered cash and designer clothing, but their ambitions escalated over time. They reportedly stole over $2 million worth of jewelry, cash, and clothing from Hilton’s home during one of the heists.
Other victims included Audrina Patridge, whose home was burglarized on the night of the 2009 Academy Awards, resulting in the theft of $43,000 worth of property.
Rachel Bilson’s residence was targeted several times in the spring of 2009, with the thieves making off with nearly $300,000 in stolen goods. Lindsay Lohan’s home was also burglarized, with approximately $130,000 worth of clothes and jewelry stolen.
Nick Prugo was among the first apprehended and confessed to the burglaries, implicating other members of the group. The subsequent legal proceedings garnered extensive media attention, highlighting the intersection of youth culture, celebrity obsession, and criminal behavior.
The Bling Ring’s exploits were later dramatized in a 2013 film directed by Sofia Coppola, further cementing their place in pop culture history.

The Bling Ring’s thefts would be equivalent to around $4 million today.
Doris Payne’s Six-Decade Crime Spree – $2,000,000+
Doris Payne, born in 1930 in Slab Fork, West Virginia, embarked on a criminal career that spanned over six decades. Her journey into the world of jewel theft began in the early 1950s, and she quickly became infamous for her charm and cunning tactics.
Throughout her career, Payne targeted numerous jewelry stores across the United States and internationally, including several in California. One of her most notable heists occurred in the 1970s when she allegedly stole a 10-carat diamond ring valued at $500,000 from Monte Carlo.
Payne’s criminal activities continued well into her later years. In 2013, at the age of 83, she was arrested for stealing a $22,500 diamond ring from a Palm Desert jeweler in California.
Over the years, Payne used multiple aliases and social security numbers to evade law enforcement. Her life of crime has been the subject of documentaries and is reportedly being adapted into a film, highlighting her notoriety and the public’s fascination with her story.
The value of the crime today
Estimating the total value of Payne’s thefts is challenging due to the span of her career and the numerous heists she conducted. However, it is believed that she stole approximately $2 million worth of jewelry over her lifetime.
Siskiyou County Courthouse Gold Heist – $2,000,000+
In the early hours of February 1, 2012, two masked men broke into the Siskiyou County Courthouse in Yreka. They stole approximately 351 ounces of gold, valued at around $1.3 million at the time.
The stolen collection included significant pieces, such as the “Shoe” nugget, a well-known specimen. The theft was discovered the following morning by courthouse staff.
Investigators from multiple agencies, including the Siskiyou County Sheriff’s Department and the FBI, collaborated on the case.
The investigation led authorities to two suspects: David Dean Johnson and Scott Wayne Bailey. Evidence included DNA matches from items left at the scene and records of gold sales shortly after the theft. Both suspects had prior criminal records.
In August 2013, Bailey pleaded guilty to second-degree burglary and admitted to a loss exceeding $200,000, resulting in a five-year prison sentence. Johnson chose to go to trial but was ultimately convicted and sentenced to a longer term.
Despite these convictions, the majority of the stolen gold was never recovered, leaving a significant cultural and historical loss for Siskiyou County.

The 351 ounces of gold stolen in 2012 were valued at approximately $1.3 million at the time. Given the increase in gold prices, this amount would be worth approximately $2 million today.
Mariposa Mining Museum Armed Robbery – $3,000,000+
On September 28, 2012, the California State Mining and Mineral Museum in Mariposa experienced a bold daytime robbery. At least two robbers, wearing hoods and armed with pickaxes, threatened workers during the heist. They smashed display cases and attempted to access the museum’s vault.
The thieves aimed to steal the Fricot Nugget, a nearly 14-pound crystalline gold mass from the Gold Rush era. However, they triggered an alarm during their attempt, forcing them to flee without it. Despite this, they managed to steal an estimated $2 million worth of gold and gems.
The California Highway Patrol led the investigation, collaborating with local law enforcement. Authorities believed the unique nature of the stolen items would make them difficult to sell.
Within weeks, authorities arrested four suspects in connection with the robbery. Some of the stolen items were recovered, but a significant portion remained missing.
The value of the crime today
The stolen gold and gems, valued at approximately $2 million in 2012, would be worth around $3 million today.
Ruggles Brothers Gold Stage Robbery – $150,000+
On May 12, 1892, brothers John and Charles Ruggles ambushed a stagecoach north of Redding. They managed to steal about $5,000 in gold coins from an express box.
The robbery turned violent when a guard, Amos “Buck” Montgomery, was killed during the heist. Charles was wounded during the robbery and captured shortly after. John was apprehended later in Woodland, California.
Both brothers were held in the Redding jail awaiting trial. However, on July 24, 1892, a vigilante mob forcibly removed them from their cells and lynched them in downtown Redding.
This event marked the end of the last major Old West stage robbery in California. The stolen gold was never recovered, fueling local legends of hidden treasure.

Walter Dimmick, an employee at the San Francisco Mint, orchestrated a daring theft in 1901. He managed to steal 1,500 gold $20 coins, known as Double Eagles, amounting to $30,000 at the time.
Dimmick was subsequently caught, convicted, and sentenced to prison for his crime. Despite his conviction, the stolen coins were never recovered.
This absence of evidence led to various theories over the years. One such theory speculated that these coins were part of the famous Saddle Ridge Hoard discovered in California in 2013.
However, experts have since debunked this theory, clarifying that the hoard was unrelated to Dimmick’s theft.
The value of the crime today
The $30,000 stolen in 1901 would be worth approximately $900,000 today.

Notably, Black Bart was recognized for his courteous demeanor and the poetic messages he left behind after some of his robberies. He never fired a shot during his heists, relying instead on intimidation and his reputation.
His criminal activities continued for eight years until a clue left at his final holdup in 1883 led to his arrest. Despite his capture, much of the stolen loot was never recovered, adding to the legend surrounding his exploits.
