Scientists found olivines among the stones thrown by the volcano Cumbre Vieja in La Palma. These are semi-precious stones used by jewelers. Since the end of last week, a sandy beach on the lava flow after falling into the ocean is visible on the Canary Island.

“Sometimes small volcanoes produce something huge, like olivine crystals found in recently ejected lava,” tweeted the Canary Volcanology Institute (Involcan), posting a photo documenting the discovery.

Olivine is a mineral of volcanic origin, one of the silicates present in igneous rocks. Usually it is light green in color, it is considered a semi-precious stone, often used by jewelers for the production of jewelry. It is found in many volcanic areas in the Canary Islands, but as the geological heritage of the islands, collection is prohibited.

“The beauty of nature always amazes, even in terrible devastation,” commented the Spanish daily ABC on Monday.

A new beach has been built

In addition, as a result of the volcanic eruption, the youngest beach in Spain was created on the strip of the first lava tongue, which solidified after falling into the ocean. According to data from the Canary Government, the island has gained an area 500 meters deep into the sea and about 820 meters maximum width, and erosion caused by the waves has created sandy spots. This first solidified lava tongue destroyed the city of Todoque 10 days after the volcanic eruption began.

So far, the lava flowing from several volcanic crevices has covered more than 1,000 hectares of La Palma, has destroyed over a thousand buildings and many agricultural crops. It forced the evacuation of over seven thousand inhabitants.
