The stone that this girl picked up is significantly lighter than other stones of the same size. It wasn’t until the stone broke in half that she understood why.
Recently, a girl living in the United States shared a lucky moment of “finding treasure” on social media. While playing on the beach, she discovered a strange stone that was remarkably light compared to other stones of similar size.
When she brought the stone home, she accidentally dropped it, causing it to break in two. Regretting her mishap, she picked it up and noticed a long scratch on the stone. Curious, she broke it apart and realized that the stone was hollow inside. This was the reason it was lighter than the others!
As if that wasn’t enough, the interior of the stone was lined with transparent crystals resembling those of quartz and crystal. It turns out that this is not just an ordinary stone but a geode.
This stone is actually hollow inside.
A geode is a type of rock formation found in sedimentary rocks and some types of volcanic rocks, which can be understood as an unfinished quartz.
The outer layer of a geode is typically limestone, while the interior contains quartz crystals. The quartz grows to fill the stone, and then the outer layer gradually erodes and breaks down, exposing the quartz. Geodes are always in a state of “rough on the outside, beautiful on the inside”, which is why rock collectors especially cherish them as treasures.
This is not an ordinary stone but a geode.
Geodes are commonly found in certain geological systems in the United States (primarily in the states of Indiana, Iowa, Missouri, Kentucky, and Utah). In 1967, the state of Iowa even chose a massive geode cave as the state rock and established the Geode State Park.
Let’s admire the beauty of geodes in nature:
Clear crystal geodes are the most common type.
