The lustrous, transparent, doubly-terminated quartz crystals from mines around Herkimer, New York, called Herkimer diamonds, present a dilemma for collectors. They are quite brittle, and found in very tough silicified dolostone.
Crystals in matrix are more interesting and more valuable than crystals without matrix, so you generally don't really want to remove them.
Trimming is best done with a diamond saw, or a pressure trimmer. If you really want to just pop the crystals off, a hammer and chisel will do that just fine.
The beautiful clear colorless doubly terminated quartz crystals called "Herkimer Diamonds" found near Herkimer, NY, can very quickly be removed from their hard rock matrix with a hammer and chisel. A diamond bladed saw would ensure a greater likelihood of success; even little diamond blades on a Dremel or Foredom tool will do. (Protect your lungs and eyes!) Bear in mind that nice crystals in matrix are more interesting, and more valued by collectors than crystals that have been broken off the matrix.
Yes, herkimer diamonds are real herkimer diamonds. From their Wikipedia page: "Herkimer diamond is a generic name for a double-terminated quartz crystal discovered within exposed outcrops of dolostone in and around Herkimer County, New York and the Mohawk River Valley." Chemically, they are different from diamond mineral, which is formed from carbon. Quartz is formed from silica, or silicon dioxide, SiO2, and is a common mineral on earth.

The same way any stone is cut, Herkimer diamonds are not diamonds, its a type of quartz.
One way to separate diamonds from Herkimer diamonds is through their hardness. A diamond is the hardest mineral (10 on the Mohs scale), so it can scratch a Herkimer diamond (7.5-8 on the Mohs scale). Another way is through specific gravity testing, as diamonds have a higher specific gravity compared to Herkimer diamonds. Additionally, professional gemologists can use advanced testing methods to differentiate between the two based on their unique chemical and physical properties.
