Crystal Classifications

Crystals are classified by a number of categories: Internal lattice structure (as discussed in How Crystals Work); Outward Structure (Shape & Form); Colour and Mineral Composition.


Let’s start with the outward structure. Points and formations have deeply significant shapes and forms according to how they formed that affect how they transmit energy.

1. Mother and Child
A Mother and Child Crystal comprises of a large Quartz Crystal with a smaller Quartz Crystal closely attached. This Crystal shape is excellent for promoting nurturing and mothering, and for conceiving a child or a creative project. It can be especially helpful in healing a damaged inner child, and helps you reconnect to the innocent, joyful child you were meant to be.

2. Abundance Crystal
An Abundance Crystal is formed from one long Crystal with many smaller Crystals clustered around its base. It attracts abundance into one’s life. Position an Abundance Crystal in the wealth corner of your home or office (this is the furthest rear left from the front door).

3. Mentor Crystal
A Mentor Crystal can be identified as a cluster of small Crystals and one larger point that the smaller Crystals surround. This Crystal shape attracts a mentor or spiritual teacher into your life. The Mentor Crystal assists in accessing information from the Akashic Record (this is the “storehouse” of all that was and all that will be in the universe). Used in a group environment, the Mentor aids teaching and sharing knowledge in the highest spiritual dimension.

4. Barnacle Crystal
A Barnacle Crystal is when a large Crystal is partially or completely covered by many small Crystals. The large Crystal is said to be the “old soul”, whose wisdom attracts the younger Crystals.

5. Twinflame / Tantric Twin Crystal
The Twinflame Crystal is formed from a pair of Crystals that are the same size, growing from the same base, joined along one side. This Crystal can be programmed to attract a soul partner – a “Twin Flame”. Contrary to popular belief, a soul-mate is some-one that we meet in life who is part of our soul journey and not necessarily our life partner. These relationships are not as easy as one would think, because they tend to carry a lot of past life karma (talk about baggage!). A twin flame, on the other hand, is your perfect match, with whom you will spend the rest of you life, and this relationship is thankfully past life karma-free. Unfortunately this particular Crystal shape is relatively rare – in it’s perfect state both points are the exact same size. The Twinflame or Tantric Twin Crystal should be placed in the relationship corner of your home or your bedroom (this is the furthest right from the door).

6. Record Keeper Crystal
The Record Keeper Crystal has clearly etched pyramids or an incised chevron shape on one of its sides. This Crystal holds spiritual wisdom and accesses both personal and collective insight. Record Keepers are extremely personal crystals and if you are lucky enough to get one, it’s best not to let others handle it.

7. Cross Crystal
One Crystal at a right angle to another, usually larger Crystal creates a Cross Crystal. Stabilizing and centring, the Cross Crystal opens you up to the multiplicity of worlds and assists you in spiritual study. This Crystal formation removes “energy impants” and also clears and activates any chakra.

8. Bridge Crystal
A Bridge Crystal grows out of another, larger Crystal. Just like a bridge, the Bridge Crystal bridges gaps and brings things together. Joining the inner and outer world, the higher self with the ego, or oneself with another. This Crystal is helpful for public speaking, especially when you are trying to communicate new ideas.


1. Point
A Crystal may be one long point (a wand), or have several points (a cluster) or have a point at either end (called a double termination).

– Single Point
In healing, aiming the point away from yourself draws off negative energy, and pointing towards you channels energy into the body.

– Double Termination
A double termination radiates and absorbs energy at both ends at the same time. This is a stone of balance, integrating spirit and matter and creating a bridge between two energy points. These Crystals are great at absorbing negative energy and breaking old patterns like overcoming addictions. Placed on the third eye chakra they help activate our natural telepathy.

– Cluster
Many big or small points forming a group and sharing a base. These Crystals send out energy into the environment and absorb negative energy. You can programme a cluster and leave it in a spot in your home to do its work. They can also be programmed to cleanse other Crystals in a room.

– Geode
A Geode is a cluster formation surrounded by rock, forming a hollow in the middle – like a miniature Crystal cave. These Crystals can hold and amplify energy within themselves, diffusing the energy softly. Geodes are wonderful for protection, spiritual growth, breaking addictions and overindulgent personalities.

– Natural Long Point
This Crystal focuses energy in a straight line. It rapidly transmits energy in healing.

– Phantom
A Phantom Crystal has a ghost-like appearance of another, smaller Crystal within it. This Crystal formed when its growth stopped for some time and a layer of minerals and dust settled on the point before the process continued. These Crystals are useful for putting the past into perspective, pointing the way towards growth and overcoming stagnation or procrastination.

2. Ball (Sphere)
Crystal balls are shaped artificially, however their shape allows energy to radiate in all directions equally. They can be used as a window into the past and future as they move energy through time – this is called “scrying”. The fortune tellers of old were on to something!

3. Square
This Crystal consolidates energy within itself. It’s a great Crystal to anchor intentions and for grounding. They can also draw off negative energy and transform it into positive energy. Flourite and Iron Pyrite can both be found naturally in this form.

4. Pyramid
Pyramids amplify and then tightly focus energy through the apex, and are able to assist you in manifesting (think “The Secret”). They can draw off negative energy and blockages from the chakra and replenish it with vibrant energy. Artificially shaped pyramids enhance and focus the inherent properties of the original Crystal used. Apophyllite is an example of a naturally occurring pyramid form.

5. Egg
Egg-shaped Crystals confine and shape energy and can be used to detect and rebalance blockages in the body. The more pointed end is also great as a massage, reflexology or acupuncture tool. They are great “hand comforters” during stressful times.

6. Layered
Crystals that form in layers or plates (like Agate and Lepidolite) are wonderful for working on several levels at once as they spread their energy out in layers. They can help you get to the bottom of things and find resolve.


Crystals can be grouped into 11 colour groups according to Judy Hall (Author of many well known Crystal books, my favourites including “The Crystal Bible” and “The Encyclopaedia of Crystals”) Each colour group share certain properties in addition to their shape and mineral properties.


Pink Crystals resonate unconditional love and work with our heart chakra. Comforting and calming, they help us to relax and release anxiety. They are amazing emotional healers; helping us forgive, let go and overcome loss, while allowing us to tune into the vibration of universal love. Crystals that are peach in colour are gentle energizers that unite the heart and the sacral chakra – combining love with action. This colour group is perfect for wearing for long periods of time.


Red Crystals resonate with the base and sacral chakra, energizing us and spurring us into action. These Crystals relight the fires of our libido and stimulate our creativity. They are extremely stimulating – but onto to be used short-term! Orange Crystals are the colour of vitality, and resonate with the energy of the sun – working with our sacral chakra. They stimulate both creativity and assertiveness – giving us the inspiration and grounding to get things done.


Yellow Crystals work with the solar plexus chakra, balancing emotion and intellect. These Crystals are wonderful for cheering us up in the winter months by bringing us the warmth and energy of the sun. Gold Crystals represent wealth and abundance. This colour group resonates with the sun and intellect.


Green Crystals resonate with the heart chakra, giving us emotional healing and inspiring more compassion. Green is the colour of nature, which is calming and soothing.


This colour group resonates with higher levels of being. Turquoise Crystals stimulate spiritual awareness and our metaphysical abilities. They instil a profound sense of peace and relaxation. Working with the third eye, these Crystals unite the heart with our intuition.


Blue Crystals resonate with the throat chakra and are the best stones to stimulate self-expression. These Crystals bring spirits of light to assist us and counteract darkness. Indigo Crystals link to the highest states of consciousness. They stimulate intuition and metaphysical abilities. Placed on the third eye chakra, they bring about a “mystical perception of the world”, whilst placed at the soma chakra they join together our spiritual identity.


Purple Crystals resonate with the crown chakra and are very spiritual. They encourage a sense of selflessness in serving others. Lavender and violet Crystals have a lighter and finer vibration that links to the highest state of awareness.


Brown Crystals are connected with the earth chakra and resonate cleansing and purifying energy. These Crystals are both grounding and protective. They are able to absorb negative energy and harmful substances, while bringing us stability.


Black Crystals are strongly protective because they trap negative energy and transform it, making them also excellent detoxifiers.


White and colourless Crystals carry the vibration of pure light, linking to the highest realms of being, and resonate with the crown chakra. These Crystals are extremely powerful energizers, purifying and healing our auras and radiating energy out into our environments.
