Unusual Discovery: Romanian Woman’s Doorstop Revealed as Million-euro Amber Treasure

BUCHAREST, ROMANIA – In a remarkable tale of overlooked value, a colossal chunk of amber, once casually used as a doorstop by a Romanian woman, has been identified as one of the largest intact amber pieces in the world, with an estimated value of €1 million (approximately Rp. 19.2 billion). The discovery, first reported by Science Alert on July 28, 2025, underscores the hidden treasures that can exist in plain sight.

The 3.5 kg stone was found at the bottom of a river in southeastern Romania, a region historically known for its amber deposits. The amber, locally known as “Romanite,” originates from the village of Colți on the banks of the Buzău River, where amber mining has taken place as the 1920s. Romanite is especially prized for its rich, reddish hues.

The extraordinary amber piece was reportedly used for decades by an elderly villager in Colți to prop open her door, rendering it inconspicuous and safe from potential thieves. It wasn’t until after her passing in 1991 that her family, inheriting the house, began to suspect the doorstop held more significance than its utilitarian function suggested.

Upon realizing the immense value of their inherited possession, the family sold the amber to the Romanian government. Experts from the ancient museum in Krakow, Poland, were then commissioned to assess the artifact. Their analysis revealed that the Romanite chunk is an astonishing 38 to 70 million years old.

“The discovery is very important both at the scientific level and for the museum,” stated daniel Costache, Director of the Buzău Province Museum. This significant find is now considered a national treasure of Romania and has been housed at the Buzău Province Museum since 2022,the region where it was unearthed.

Evergreen Insight: This extraordinary discovery serves as a potent reminder of the potential for immense value hidden within the ordinary. Throughout history, countless artifacts and natural wonders have been overlooked or repurposed due to a lack of immediate recognition. This incident mirrors the story of a man in Michigan, USA, who found out many years later that a large rock he’d used as a doorstop was actually a meteorite worth $100,000. such instances highlight the importance of curiosity, historical preservation, and the ongoing potential for scientific and monetary revelations in unexpected places. They also underscore the enduring value of natural resources and the stories they hold, often dating back to the dawn of civilization.

Rare Stone Sparks Billion-Dollar Auction: Indonesian Grandmother’s Mystical Find

The Discovery in Sulawesi

A seemingly ordinary stone discovered by an Indonesian grandmother in the remote region of Sulawesi has ignited a global frenzy, culminating in a hotly anticipated billion-dollar auction. The stone, initially believed to be a common rock, has been identified as a remarkably rare Serendibite – a mineral so elusive that gem-quality specimens are exceptionally scarce. This particular stone, weighing in at an astonishing 170 carats, boasts an unparalleled clarity and vibrant blue hue, contributing to its exceptional valuation. Sulawesi, known for its rich biodiversity and geological formations, is increasingly becoming a hotspot for rare mineral discoveries.

What is Serendibite? A Deep Dive

Serendibite is a magnesium aluminum borosilicate mineral first discovered in Sri Lanka (formerly Serendib) in 1902. Its chemical formula is (Mg,Fe)Al2(BO3)(SiO4)O2. Here’s a breakdown of what makes it so special:

Rarity: Fewer than a handful of gem-quality Serendibite stones have ever been found. Most specimens are opaque or heavily included.

Color: While Serendibite can occur in various colors, including green, brown, and black, the blue variety is the most prized and incredibly rare. The intense blue color is attributed to trace elements within the crystal structure.

Hardness: With a Mohs hardness of 6-7, Serendibite is durable enough for jewelry applications, though it requires careful handling.

Geological Formation: Serendibite typically forms in high-grade metamorphic rocks, specifically those rich in boron.

The Grandmother’s Story & Initial Assessment

Pakde Aminah, the 72-year-old grandmother who unearthed the stone, initially used it as a paperweight. She noticed its unusual shimmer but didn’t realize its potential value.Local gemologists were initially skeptical, accustomed to more common finds. Though, a visiting mineralogist from Jakarta recognized the stone’s unique characteristics and recommended further analysis. Autonomous laboratory testing confirmed its authenticity and exceptional quality, sending shockwaves through the gemological community. the initial assessment valued the stone at $3 million, a figure quickly surpassed as news spread.

Auction Details & Bidding War

The auction,hosted by Christie’s in Hong Kong,is scheduled for August 15th,2025. Pre-auction estimates now range between $800 million and $1.2 billion,driven by intense interest from private collectors,museums,and high-end jewelry houses.

Key Bidders: Rumored bidders include Sheikh Al Maktoum of Dubai, renowned gem collector Robert Mouawad, and representatives from the smithsonian institution.

Auction Format: The auction will be a sealed-bid format, with bids accepted until the closing date.

Proceeds: Pakde Aminah has stated she intends to use the proceeds to improve infrastructure and education in her village,as well as establish a foundation to support local artisans.

The Impact on Indonesia’s Gemstone Industry

This discovery has the potential to significantly boost Indonesia’s gemstone industry. While Indonesia is known for sapphires, rubies, and emeralds, the Serendibite find highlights the country’s untapped potential for rare mineral discoveries.

Increased Exploration: The Indonesian government is expected to invest in geological surveys and exploration programs to identify other potential gemstone deposits.

Local Economy: The influx of investment and tourism related to the gemstone industry could create jobs and stimulate economic growth in remote regions like sulawesi.

Ethical Sourcing: The story emphasizes the importance of ethical gemstone sourcing and ensuring that local communities benefit from natural resource extraction.
