Erupting Kilauea volcano not raining gemstones

University of Hawaii geology professor Michael Garcia shows a piece of olivine embedded in a chunk of lava from a prehistoric eruption of Kilauea volcano in his office in Honolulu on Tuesday. Olivine is a common mineral in Hawaiian lava, but the olivine from a current Kilauea eruption is much smaller and harder to extract. (AP Photo/Jennifer Sinco Kelleher)

Olivine is the reason Hawaii Island has a green sandy beach called Papakolea, which is pictured. (Chelsea Jensen/West Hawaii Today)

HONOLULU— The ongoing eruption of the Kilauea volcano is not causing crystals to rain from the sky despite reports of residents finding little green gems in the area.
