Healing crystals are mostly sold by them who deals in metaphysical crystals and its products like citrine, rose quartz, malachite and others. Online metaphysical stores are where you can buy these types of powerful crystals easily at good prices.
In general, sedimentary rock crystals would be crystals that are found in sedimentary rocks. Normally they are calcite or quartz as they are the minerals most likely to cement sediments to form sedimentary rocks. There is a group of sedimentary rocks called evaporites that include crystals of salt, gypsum, sylvite, glauberite, thenardite, mirabilite and a few others. However, there is a tremendous variety of other minerals that can produce crystals in sedimentary rocks. Geodes from Indiana, Illinois, and Kentucky can have crystals of barite, millerite, sphalerite, galena, fluorite, and aragonite. In other areas of the planet crystals of azurite and malachite can be found in sedimentary rocks. There are many, many other types of crystals that have been found in sedimentary rocks.
Ceramics, glasses, minerals and aggregates of cemented of minerals (i.e. rocks) are all examples of brittle solids. There are probably many others you can think of!
The size of the crystals depend on the time it took the rock to cool. Slow cooling rocks have larger crystals because they had a longer time to grow their crystals. For example Basalt is an volcanic extrusive igneous rock that forms from rapid cooling of the magma and are usually located near the surface or on the ocean floor, it has finer crystals not visible by the naked eye. Granite is an intrusive igneous rock that forms from slow cooling of the magma within the earth crust, it has larger crystals.
Different igneous rocks have different crystal sizes because they have cooled at different rates. Those with larger crystals have cooled at a slower rate. A single rock sample can have varying crystal sizes because there are different minerals within it. It is consistently the Quartz crystals in Granite which cool fastest, leaving less space for the Mica, which forms later. This means that the Quartz crystals are larger than others in the rock, resulting in an inconsistency in size.
Some crystals do, such as sugar. Others, like salt, don't depend on the temperature of the liquid. All crystals are different.

Partial melt. Some crystals will melt at lower temperatures then others, so during a given temperature range, only a part of the crystals in a rock will be molten.
Minerals can do many things. They can balance out with the vitamins you need in your body. They are able to make your hair and others grow faster on your body.

Because of their chemical composition, feldspars are more easily attacked by mildly acidic rainwater than say a quartz would be.
Some are, not others.
.Making work faster .finding the answer faster through research in the internet than just reading a book .communicating others easily and faster by using e-mail than sending a letter.
it will cool faster in a metal cup. - the others retain heat better.
why are some objects faster than other
Certain minerals are stronger than others because of the way their atomic structures are arranged.
Fluorite does not go with the others. It belongs to Halide minerals, while the others (quartz, feldspar, and hornblende) belong to Silicate family of minerals.
