Gemstones are not just pretty; they’re also fascinating because new ones are being found all the time. For example, recently discovered gems include aquadité, Welo opal, and new types of rubies and sapphires. 

Finding new gemstones is like uncovering hidden treasures from the earth. Each new discovery adds to our understanding of the beautiful and diverse world of gemstones.

Recent Significant Gemstone Discoveries

In the past 100 years, there have been some exciting finds in the world of gemstones. These discoveries include both completely new gemstones and new variations of ones we already know.

Aquadité was first found in April 2022 on the Maluka Islands in Indonesia. It was discovered by accident when miners hit a rock while clearing a road.

This gemstone is a type of chalcedony, which is a form of quartz, and it has high amounts of copper in it. The copper is what gives aquadité its distinct color.

Aquadité has a striking blue-green color, similar to the hues of tropical ocean waters. When light hits it just right, the stone appears to glow from within, which is really neat to see.

Yooperlite is a type of syenite rock that contains fluorescent sodalite. This composition is what makes the stone glow under ultraviolet light.

In daylight, yooperlite looks like a regular gray rock. But under UV light, it glows with bright orange or yellow colors.
