Some samples of zeolites and associated cavity minerals.
I had to take the pictures from behind a glass pane so excuse the lack of extreme close ups.
Take a stab at identifying the minerals and post your answers in the comments. I will put up the correct answers in this post in a few days.
Update: Answers at the bottom.
These palm sized samples were selling in the range of Rs 5000 to Rs 10,000 (~ $100 to $200). Larger samples were in the range of Rs 25,000 to Rs 60,000. These are prices for the Indian market. I imagine there will be a significant markup for sale in the U.S and Europe, Japan etc.
Ornamental zeolites have become quite a lucrative business.

A) pink - stilbite, green - apophyllite, needles - scolecite , few crystals of heulandite in the centre of the sample.
