The beach sands collected from Clearwater beach contains many transparent crystals. These crystals are very hard. Rather than being grinded and polished into rounded shape. They seems to maintain the original shape.
I put them in the homemade polarized light microscope. The color of the crystal turns into brilliant colors due to the deflection of light by the irregular shape of the sand. The color pattern is very much like the color of the lace agate’s quartz under the polarized light microscope.
The above picture was taken with Canon EOS T1i camera in manual mode. The camera was attached to the microscope with a 0.5 X reduction adapter.
The beach sand of Gulf Mexico: the beaches on the gulf of mexico are famous for their sparkling water and sugar white sand. On my spring camping trip, I collected some beach sand on several beaches, including Siesta Beach which ranked #1 on Dr. Beach’s top 10 beach in the US.
