Discovery Near Rathnapura: The Pure Earth Star Had Rare Asterism Confirmed in January After Independent Assessments and Entered the Radar of the Global Market for Historical Gems
A unique purple star sapphire was discovered in Sri Lanka, weighing 3,563 carats, named the Pure Earth Star, potentially one of the most valuable gems ever found, following a recent technical evaluation.
Found in 2023 in a mine near Rathnapura, known as the city of gems, the stone had its potential recognized two years later, after independent certifications.
The confirmation occurred this January, according to consulting gemologist Ashan Amarasinghe, responsible for the technical evaluation requested by the owners, who remain anonymous for safety.

After China, it’s now the turn of the USA to ‘secure’ a share of Brazil’s natural resources: the country buys critical rare earths for R$ 3 billion and enters the center of the global technology dispute.

Rare earths are in everything, from cell phones to bullet trains, and what almost no one realizes is why they have become the target of such a delicate global war.

Brazil extracts 26.3 million tons of ore from what was previously treated as waste, transforming residues into wealth, producing over 3 million tons of sand, and demonstrating how national mining is relearning to generate value.

A $3.5 billion megaproject in Latin America pumps desalinated seawater at 1,050 liters per second over 194 km to keep a copper supermine in the Andes operational for another 20 years.
Rare Asterism Distinguishes the Gem
According to Amarasinghe, the Pure Earth Star exhibits exceptional asterism, an optical effect that creates a well-defined star with six visible rays on the surface.
The phenomenon occurs due to the presence of microscopic needle-like inclusions of the mineral rutile, responsible for reflecting light precisely.
According to The Natural Sapphire Company, an ideal star sapphire displays a centered star, continuous rays, and balanced proportions from top to bottom.
These characteristics are considered extremely rare and are said to be fully present in the gem found in Sri Lanka, according to recent technical evaluations.
Evaluation and Value Projection of the Rare Sapphire
The official value has not yet been determined, but international appraisers estimate a price between US$ 300 million and US$ 400 million, as informed by Amarasinghe.
If confirmed, this figure would place the Pure Earth Star above famous stones like the Oppenheimer Blue, which sold for US$ 57.5 million in 2016.
Another parameter cited is the Williamson Pink Star, sold for US$ 57.7 million in 2022, amounts significantly lower than the current estimates.
Factors That Increase Value
Experts from Jeweler’s Touch explain that exceptional gems combine beauty, unique color, structural rarity, and a singular journey over time.
These elements transform certain stones into historical references in the international market, with symbolic and financial value that is practically immeasurable.
The discovery reinforces the relevance of Sri Lanka as a source of rare gems, maintaining the local tradition associated with specialized mining and cutting.
Before the recent certification, the stone remained under private analysis, without public exposure, awaiting complete technical confirmation of its characteristics.
With official recognition, the Pure Earth Star becomes part of the exclusive group of historical gems that redefine rarity parameters.
