Star sand is a biogenic "sand" made of the star-shaped exoskeletons of tiny, single-celled sea creatures belonging to the Foraminifera group.
Foraminifera, Latin for "hole bearers", are single-celled organisms, members of a phylum or class of amoeboid protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly an external shell (called a "test") of diverse forms and materials.
Most foraminifera are marine, the majority of which live on or within the seafloor sediment, while a smaller number float in the water column at various depths are planktonic. Star sand is considered planktonic foraminifera.
This sample is from Ishigaki Island in Okinawa, Japan. This type of sand can only be found on a few beaches in the world.
This delivered very quickly and it was just as beautiful as the photos. Love it!
I’ve been wanting star sand from Japan for a while. What sold me on this was the round container that it comes in…I can look at it without opening it and it looks great displayed as is! Very happy with this purchase.
Awesome product! Exactly as advertised

Neat! The flat plastic case makes it easy to observe without spilling it, but I love that all of the containers from this shop are unsealed so I *can* touch it if I want. Lots of little spiky guys in this star sand.
Order came quickly and my grandson is on his way to learning some science!!
Arrived quickly and was of great quality - thanks!
