Two etched laser crystals. Both crystals are about 2" square. The taller one with the teddy bear, hearts, stars.... is 4-3/4" tall while the shorter one with the dolphins is 3-1/4" tall. I don't happen to have any of the light bases for these but they are easily obtained online and if you get a color changing one it adds some pretty nice effects to the crystal. A picture of a light base is shown in the last image. Set in the proper sunlight you get a prismatic effect from the sunlight passing through the crystals.
