Summarize this article in one sentence.
An easy and efficient way to separate your crystals is by their finishing method. Some crystals have a shiny, smooth outside, and they go through a polishing process to tumble them. Raw crystals refer to stones that are not tumbled and still look as if they came out of the ground. Separate your crystals based on these categories before you place them in your storage solution.  In addition, some crystals such as Selenite or Labradorite are really sensitive and can break easily. For instance, you can place all of your tumbled stones in a box and put your raw specimens on a bookshelf. If you collect crystals to use for their healing potential, you may find it helpful to group your crystals by color. Make a pile for any red, orange, yellow, green, blue, purple, clear/white, and black crystals. This way, you can easily pick out a perfect stone to use during your healing session.  For example, if you want to feel more grounded and secure, select a piece of garnet to use while you’re meditating. To increase clarity and focus, pick a piece of quartz to keep on your body throughout the day. If you have a few favorite types of crystals and have several in your collection, it may work best for you to sort your collection based on individual crystal type. You can also arrange your crystals based on size. Put the large crystals toward the back, and place the small ones along the front. For instance, do this if you have a lot of amethyst, tourmaline, or smoky quartz.

Summary:
Sort your crystals based on if they are tumbled, raw, or fragile. Group crystals based on color or chakra to work with a certain energy. Organize your crystals based on type and or size for uniform options.
