A mineral is a naturally occurring solid formed through geological processes and to be classified as a true mineral it must have a crystalline structure. There are currently more than 4,000 known minerals/crystals and of these about 150 can be called common, the rest rare to extremely rare.
Calcite – forms in limestone rock and depending on the chemical reaction within the rock dictates the colour.
Opals - are found in sedimentary rock e.g when rain washes shale and gravel from the rock face.
Quartz – is common in sandstone rock as it contains a high percentage of silica (gypsum)
Selenite – is formed when the gypsum of quartz is grouped together with alabaster and calcium sulphate and this is found in base rock and clay beds. The Greek meaning of selenite is the moon.
Desert Rose – occurs when the soft gypsum or silica form in arid sandy conditions e.g the desert.
Some of the major varieties are:
Agate – Multi coloured and banded.
Amethyst – Purple to transparent.
Carnelian – reddish orange.
Citrine – Yellow, reddish orange, greenish yellow.
Jasper – Opaque crystalline, red, or brown.
Onyx – Agate where bands are straight/parallel.
Rose quartz – Various shade of pink.
Rutilated – Contains needles of rutile.
Smoky – Brown, grey, opaque.
Tigers eye – Fibrous gold, red, and brown.
Crystals can be worn on or kept close to the body – these work on the energy field and will therefore affect the whole body (used for healing/protection).
Kept under the pillow – this will help with sleep problems like insomnia, ward of nightmare or help with dream recall.
Used in the bath – this will absorb any negative energy or emotions – good for healing (aventurine, rose quartz, and amethyst).
Meditation – the energy structure impairs a stillness, helping to quieten the mind. Place the crystal in front of you or hold it in your hand (quartz, elestial quartz, moldavite, or labradorite).
Home or Workplace – crystals will alter the energy of a space and add harmony. Rose quartz, amethyst cluster or any raw cluster as they will retain more negative energy.
Gem or Crystal water – place clear and rose quartz in a jug of tap or spring water and keep in a fridge for up to 10 hours before drinking. This can also be used as a facial/body spray or added to bath water.
