At least 3 small Milarite prisms rest on the crystalline muscovite base of this cabinet piece. The crystals reach maximum dimensions of 5 x 2 mm, though two of them are much smaller than the third. All are in excellent condition, showing no damage, and show good though somewhat warped hexagonal prismatic form. Their color is white and their luster is silky, and they are translucent at best. The muscovite base is in good condition and consists of countless intersecting "books".

Dims: 1.7 x 1.2 x 0.9" (4.3 x 3.0 x 2.2 cm)

Several stubby, white Milarite crystals rest on the base of this small hand piece. These crystals do not exceed 0.3" (8 mm) in length or 0.1" (3 mm) in diameter but I believe that this size is considered large for crystals of this specie. All have a somewhat warped hexagonal prismatic form, as a hexagonal outline is not very clear, and have a white color and a surprisingly silky luster. Their crystalline base appears to be made up of albite, of the variety known as cleavelandite, due to its strong pseudotrigonal patterning.

Two complete and two partial Milarite crystals rest on the albite base of this hand specimen. The largest complete crystal has dimensions of 4 x 2 mm, and the other complete one is much smaller. They show a moderately good hexagonal prismatic form; the broken ones show it better, with definable hexagonal cross-sections. All have a white color and a silky luster, and are transparent. The albite base on which they rest is of the variety called cleavelandite, and shows excellent pseudohexagonal blades.
