Photo 1: Dogtooth Calcite. More on the rare side being clears, whites with yellow. Found in Morcco, acts as a bridge between realms, it's ideal on ancestral altars, divination, or if you are a reader, place near you while doing your reading for clarity. Also known as the ascension stone, placing near your bed while you sleep can help you astral travel.  Many people use it to have a clear connection with deities during ritual work. This is a nice piece. 

Photo 2-4 (sizes vary) Herkimer Diamonds. Super High Vibration!
These sit deep near water in caves over thousands and thousands of years, they are used to clear and recharge other crystals, they banish all stagnat energy and when used with money work they are crazy efficient. 
These have been through all of my money workings, Some with Saint Expedite, Fortuna, and various others over the last 10 years. It's time to pass them on. all you need is a small one, in photo they are near ruler for size. weights below.
