These unique crystals are energetically connected to all other seed crystals and excellent to use for channeling work. They are said to have been planted in the last days by an ancient civilization known as the Lemurians programmed to transmit a message of oneness, with a message of love and equality. Lemuria is said to have been a civilization whose consciousness was centered on the spiritual and emotional. The striated edges of these crystals resemble a bar code and are said to hold the Lemurian knowledge left for future generations to contemplate. Activated by rubbing the striated surface. Aids chakra clearing, healing and dreams.
Lemurian crystals are attracted to people who will actively assist in enhancing the energies that aid the planet. It has been said that Lemurian crystals are the perfect stone for opening the heart. They put one in touch with the purity of innocent emotions and enhance one’s intuitive gifts. Great for removing energy blockages and opening to Divine love and Compassion.
 
Trigger Crystals are quartz crystals with a smaller crystal that is growing out of the side of the body of the bigger, older crystal.
You can use them during meditation or when doing a healing, and they are activated by squeezing the smaller crystal.
This will send an extra burst or surge of energy through the main crystal, which may elevate the metaphysical attributes of the bigger crystal.
Trigger crystals are particularly useful, when they are of a quartz variety, or formation that you feel would be helpful for healing a specific physical, emotional or spiritual problem that you wish to have healed. 
By boosting the intensity of the energy of the bigger crystal you may receive a better healing outcome. I particularly like the fact that this trigger crystal shown here is a Golden Healer Lemurian, and as well it is a double terminated crystal and a barnacle crystal.
So if you had a need for any of these quartz configurations, the trigger crystal could accentuate the energy, and this crystal has an amazing energy which the trigger is powerful to boost.
 
Barnacle Crystals - These are tiny sparkling crystals which form on and around a larger crystals. They give the piece a purpose of uniting and healing groups and gatherings.
 
ISIS CRYSTALS have five edges surrounding the largest sloping face. These crystals strongly amplify the feminine energy, and can help you get in touch with the 'female' or unselfish side of yourself, no matter whether you are a man or a woman. These crystals are useful in balancing your male-female energy if the female energy has been suppressed, or if you need a greater balance of female energy for any reason. Isis crystals put you in touch with the power of the Goddess.
For men, the Isis crystal will help you become more in tune with your feminine side and to become more aware of the aspects of women that you may find troubling.
For women, the Isis crystal will help you regain some of the power and energy that society has taken from you. Teaches that feminine is not weak. Anyone doing healing work with another person needs the Isis energy to be effective.  The Isis crystal should be carried or held when dealing with issues that are emotional and difficult.
Exercise: Isis crystals can be used to project nurturing energy toward another person. To do this, sit quietly with the Isis crystal in your hand with the point directed away from you. Visualize the person that you wish to help and visualize white light going from the point of the crystal and surrounding the person.
To nurture yourself, sit with the Isis crystal in your hand with the point directed toward you. Visualize white light going from the point of the crystal and surrounding you. After doing this you should feel strong and cared for.
