The Hawaiian islands are actually undersea volcanoes. Most of the volcanoes are no longer active, but some continue to erupt. The sparkling black sand covering some Hawaiian beaches formed when hot lava from the volcanoes flowed into the ocean.

∙ 13y agoWhile it is tempting to say that we just wanted it to look different, the black sand (and green sand) found on a very few beaches is volcanic rock that has broken down to very fine particles. EXTREMELY hot to walk on in sunlight, it is a true deep glossy black. And kind of neat.

Where is black sand?
Black sand is sand that's been turned a black color either by a glossy partly-magnetic mix of sands (usually fine), or by tiny fragments of lava.Some gold and white beaches can also contain black sand, typically after storms have sorted out grains where heavier, darker particles remain on the surface.There are many black sand beaches around the world. Prince William Sound, in Alaska, and Lost Coast, California, both have black sand beaches named Black Sand Beach. Hawaii has Kehena Beach, Oneuli Beach, Polulu Valley Beach and Kaimu Beach. Maui hosts Oneuli Beach, Honokalani Black Sand Beach and Waianapanapa Black Sand Beach. Finally, Vik Beach in Iceland has some breathtakingly blue water surrounded by eroded rock formations beyond a beach of black sand.For more black sand beaches, try a Web or Image search on Google or your favorite search engine for black sand beach.

However, Japan has also many white sand beaches, which are made of white coral sand (southern islands) and white quartz/limestone sand (peninsulas on mainlands).

Volcanic beaches are black because the sediments on the beach come from volcanoes. In other words, if a beach is black, that means that there was or is volcanic activity in the area.
Does sand consist of sea shells?
MOST sand consists of broken down rock (silica dioxide). However, on islands, such as Hawaii, most sand is broken down coral (calcium carbonate). This is why most beaches in Hawaii are tan colored, and not white.
