Here is a great sample of square prismatic Apophyllite from Nashik District, Maharashtra, India.
The size is 130 x 70 x 45 mm, and the weight is 399 grams.
It is damage free and a great specimen for display.
Please watch the videos for the best view.

My father bought this one from miners in India about 30 years ago, and have kept it ever since then.
