Crystals General Rules

Home/Crystals General Rules

The general rules below can help you and those you know stay safe.


  • *If the crystal name end with "ite", are potentially toxic and harmful to your health. They should also be treated as water soluble. Use indirect method when using  the crystal as an elixir. Research your specific crystal for more information.

  • ​Learn about the Mohs

  • Do not place any of the following stones in the sun, or store them where they will be exposed to sunlight, they can fade:

  • Amethyst, Rose Quartz, Aquamarine, Smoky Quartz, Kunzite, Hiddenite, Spodumene, and Fluorite.

  • Pyrite degrades when stored at high humidity. 

  • For the protection of the stone it should be stored in an airtight container, in areas of high humidity place silica drying gel in the container to absorb moisture and replace when necessary.

  • Calcite, Gypsum, Limestone, Marble and some other stones will dissolve in acid solutions, even weak ones such as vinegar.

  • A dilute acid solution is used to dip Calcite specimens in to get the smooth, glassy surface they generally have.

  • Amber dissolves in acetone which is contained in most nail polish remover.

  • Quartz: Iron stains can be removed from quartz crystals and other similar materials using CLR or Lime Away.

  • Be sure the mineral will not dissolve in the acid before using this method for materials other than quartz by testing on a hidden area.

  • Be sure to wear rubber gloves, and apply with a soft cloth or scrub with an old toothbrush.

  • Quartz group minerals are for all practical purposes stable in a normal household environmentBesides, amethyst, quartz group are not harmed by light, changes in temperature in the normal comfort range, or known to decompose.

  • Quartz group specimens can be fragile and should be handled with care like any other mineral specimen.

  • Quartz group minerals are not appreciably soluble in water. But ... this is a group of minerals, and all sorts of exceptions apply.


You may wish to watch out for the following:


Many Quartz crystals, including Amethyst, etc., contain small voids filled with water and gas, so-called 'enhydros'. 
Over time the water may evaporate, leaving just a void. The water will not  be 'sealed in'.


  • Water vapor easily passes through Agate and Quartz. Meaning, it doesn't require long cleansing time.

  • Such specimens may also be susceptible to damage if exposed to high temperatures or sun light.

  • Keep them in the shade, and don't cry when the water is gone. 

  • Some Amethyst and some Rose Quartz is susceptible to fade, when exposed to sun light.

  • The rule of thumb is, all Amethyst fade, but most of it fades slowly, and Rose Quartz colored due to phosphate (chiefly Rose Quartz crystals and material from a few Brazilian localities) fades rapidly, but Rose Quartz colored by Rutile does not fade.

  •  Many brightly colored Agates are dyed, and some dyes fade. Blame that on the processor, not the rock! Some natural colored Agate may fade too, though.​

  • Opal:The play of colors in precious Opal is due to the intergrowth of different crystalline and amorphous phases and to water. Consequently, the colors are often lost when the Opal 'dries out', which may be promoted, delayed, or even prevented, depending on storage conditions. Common Opal is subject to the same process, but the visual impact is rarely as profound, though specimens may literally crack.

  • Garnets: These are stable in a normal household environment - it is one of the most stable and inert minerals known.

They are not harmed by light, changes in temperature in the normal comfort range, or known to decompose.

Garnets specimens can be fragile and should be handled with care like any other mineral specimen. 

Garnets are not appreciably soluble in water.

  • ​Never heat cinnabar, realgar, or stibnite. They produce poisonous gases.​

  • Wash your hands after handling them and do not eat or smoke while working with them. ​

  • The types of stones that are toxic to ingest are minerals/ metals containing copper, lead, arsenic, cadmium, aluminum, barium, mercury, and zinc.​

  • These substances are often what gives a stone its characteristic coloring or shape.

  • Variscite - aluminum 

  • Wulfenite - lead, molybdenum​

  • Do not make conventional gemstone elixirs, gem waters, massage oils, or consumables of any stone containing metal (lead, copper, etc.)

  • ​Polished stones are less likely to allow elixirs, etc. to leach any potentially hazardous materials.

  • Rough stones are most likely.

  • ​In general, almost all blue and green stones, especially brightly colored ones, contain copper and are unsafe to use for gem elixirs, etc.

  • Shiny, metallic stones should be avoided.

  • Don't handle stones containing arsenic, such as realgar, or mercury, such as cinnabar without protective gloves. Wash hands thoroughly with soap and water after handling them. These stones are extremely toxic.

  • Do not eat, drink, or smoke while handling potentially toxic stones.

  • Keep all potentially harmful stones (including small, bite-sized stones that aren't necessarily toxic!) out of reach of children for safety.


Radioactive minerals: Precautions for storing radioactive minerals are as follows:

Handle the specimen as little as possible. A good strategy is to place the specimen in a transparent container which is sealed.

Wash your hands after handling the specimen.

Do not smoke, eat, or sleep near the specimens.

Limit the specimen size since exposure is related to the amount of mineral present.

Secure the specimen from children or curious adults.

Alpha and beta radiation is absorbed by a couple of feet of air or by a glass cabinet window.

Gamma radiation is not.

The main environmental exposure hazard from radioactive minerals comes from the buildup of Radon gas emitted by Uranium- and Thorium- bearing minerals.


Museums who display large radioactive specimens provide vents to the outside. A good strategy for personal collectors is to place a cheap aquarium pump inside a closed mineral cabinet. Route the output of the pump to the outside.


Not to be cleansed in Salt Water:

  1. *Alabaster

  2. *Calcite

  3. *Carnelian

  4. *Hematite

  5. *Labradorite (Spectrolite)

  6. *Lepidolite

  7. *Moldivate

  8. *Opal

  9. *Turquoise

  10. *Ulexite


*Use caution only with the softer Mica and crystaline stones


May fade in Sunlight:


For energy, carry the stones with you, either in a little pouch around your neck or in your pocket or pocketbook.


* For meditation , hold the stone in your hand or set it in front of you. If in a meditation group, sit the crystal in the center of the group for collective consciousness.


*For healing. In a full-scale crystal working, ask the stone for its energies and utilize them. For healing, place the crystal on the part of the body where you need it. For Chakra and Aura work , choose crystals of the appropriate color and properties. Place the stone on the afflicted area and feel it's energies work as it re-balances the energy centers.


You can hold the stone in your receptive hand to absorb the healing energies.


At the end of the process, the stone is probably depleted of much of it's energy.

Thank your crystal and then cleanse it. Remember, most stones will retain these negative energies.


* For crystal elixirs: place the stone in a bottle and fill the bottle with distilled water, Place it in the sun/moon for 24-48 hours, then use the water as a topical spritzer or rub. The water is "energetically charged" by this process.
