This is a lot of two specimens of catapleiite of rather different habits.  

The first specimen is an interesting 7 mm “rosette of rosettes” of thin platy catapleiite. The dimensions given are for this specimen. It isn’t exactly a micro, but you will need some magnification – perhaps 3-5X to see the structure clearly. This specimen is shown in the first pair of photos.

The second specimen (1.2 x 1.7 x 1.1 cm) features numerous inter-grown crystals of catapleiite. The next pair of photos is a close-up of one of these crystals. It is 4.2 mm in diameter. There are several similar crystals on the specimen. But you will need a scope (10-15X) to appreciate them. The specimen looks good in the full-view photo - becuase macro makes it look "larger than life". But hand-held, it doesn’t look very impressive. It's really a micro!

Combined shipping weight 3.0 oz. Outside the USA, the stated postage and packing rate applies up to a total weight of 8 oz (225 g). Within the USA, there is a nominal increase of $0.20 for each additional ounce. Above 13 oz, I will use Priority Mail. Up to 16 oz, the “own box” Priority rate is $9.25 (including packing).

These specimens could be sent in a padded envelope, but the postage is the same.
