While digging a well, a worker hit a 'rock' worth more than 2,300 billion VND.

A group of workers in the city of Ratnapura, southern Sri Lanka, accidentally dug up a large rock while digging a well. This rock weighs up to 510 kg and has a very strange appearance. This rock is light blue and shines iridescently under the sun.

Seeing this, they immediately informed the homeowner. Gamaga - the homeowner, a gem businessman, knew at first glance that this rock was not ordinary. It could be a giant sapphire.

Many gem experts were invited to examine it, and they confirmed that this was a star sapphire. According to the experts, this is a group of stones bonded together by mud and clay. It took them more than a year to clean the impurities and mud stuck on this gemstone. Many high-quality star sapphires fell out of the cluster after cleaning, and they could not determine how many there were. According to the estimated market price, this sapphire block is worth up to 100 million USD (more than 2,300 billion VND).

They decided to name this sapphire "Serendipity Sapphire" (meaning Accidental Sapphire) after the nature in which it was found.

Star sapphires are sapphires that, when illuminated, reveal a six-pointed star. Star sapphires are rare and highly sought after gemstones. Their value depends on many factors: weight, color, shape, and the sparkle of the star hidden within.

Star sapphires are mainly indigo blue, gray, and blue-gray. In the gemstone, three groups of densely arranged silk-like inclusions can be seen with the naked eye. The formation of starlight is due to the reflection of light by impurities in three groups of directions. There are bright spots concentrated in the center of the starlight, and the star lines gradually become thinner as they extend to the edges. Because the bottom surface of natural star sapphires is mostly unpolished, straight or angular bands and small step cracks can be seen. The luster of star sapphires is oily and feels heavy when held in the hand.

If the color of the raw sapphire is not beautiful, the tone is not suitable and the transparency is poor, the value will be relatively low. But if it has a star effect, its value will increase. The "Starlight" sapphire is as clear and transparent as the blue sky of the Indian Ocean, and is known as the best type of sapphire.

In the natural environment, such stones can be found in the form of ordinary nuggets, while they come in different sizes, sometimes resembling ordinary pebbles. So you can find a lot of stories when ordinary people use stones in their homes, not even knowing their real price.

Star sapphire is a special type of sapphire and the price of good quality star sapphire is 10,000 USD/1 carat. In addition, the price of sapphire is also related to the quality and origin, for example, sapphire produced in Myanmar, Sri Lanka, Kashmir, India is often high value and has many high quality products.
