    Kilauea volcano eruptions are raining green gems on Hawaii’s Big Island as spurts of lava and ash continue into their fifth week

    The eruptions of Hawaii’s Kilauea volcano have rained tiny green gems known as olivines onto the island’s streets and beaches.
    The minerals are found in volcanic rocks and land around Hawaii.
    They have always been there but have been dislodged by the recent eruptions and are coming shooting down on resident as a result. 
    Some have collected the minerals from beaches and streets since they were spurted out and say it is proof of the wonders of nature.   
    Olivine is a green mineral which, in its magnesium rich form, is known as Peridot. 
    Peridot has been used for centuries to make jewellery and, in some cases, can be worth as much as $450 per carat. 
    This week, locals shared photographs of the small olivines on social media after collecting them.
    They called them ‘Kilauea’s little gems’ and said: ‘It’s literally raining gems!’
    Cheryl Gansecki, a geologist at the University of Hawaii-Hilo that studies the composition of Kilauea’s lava, told Mashable that there were two reasons the gems were being discovered more frequently because of the eruptions. 
    ‘The lava that is erupting now is very crystal-rich and it is quite possible that residents might be finding olivine. 
    ‘It can be carried in the pumice [rapidly cooled lava] pieces that have been rained all over the area or left behind when weaker lava rocks are crushed,’ she said.  
    Olivine is commonly found in lava samples and in rocks around Hawaii. 
    Stanley Mertzman, a volcanologist at Franklin and Marshall College, said: ‘The olivine crystals folks are finding on the ground scattered about are from violently ejected basalt [a type of lava] blobs wherein the embedded, earlier-formed olivine crystals are freed from their surrounding pahoehoe [syrupy lava] basalt liquid.’
    Kilauea erupted again on Thursday, spewing ash onto the Big Island. 
    The volcano has been erupting for 43 consecutive days, placing homes, lives and businesses at risk.
