The following are excerpts from "Archangel Oracle Cards" by Doreen Virtue, Ph.D.

• Ariel’s aura is a pale shade of pink, and if you wear or hold a rose quartz crystal, your heart will open further to Ariel’s magnificent love. Ask her for whatever you need, and she’ll guide you accordingly.
• Azrael’s aura is a beautiful shade of vanilla cream: a very pale yellow tone. He surrounds grieving and dying persons with this loving light to bring them comfort. When Azrael is around, you may see eggshell-colored lights in the room. The crystal, creamy yellow calcite is calibrated to Azrael’s energy, so holding or wearing this crystal may lend additional comfort.
• Chamuel’s aura is pale green, like a springtime leaf in the morning sunlight. You can feel close to Chamuel’s loving energy by wearing or carrying a green fluorite crystal.
• Gabriel’s aura is copper, like her trumpet. When you wear the crystal stone citrine, or the precious metal copper, you readily connect with her energy.
• Haniel’s aura is bluish-white, like the moon’s glow. The crystal associated with Haniel is the moonstone, which has magical, nurturing energy associated with it. Wear or hold a moonstone whenever you wish to feel close to Haniel. She will care for you with her nurturing mother energy and effect miracles with her love for you.
• Jeremiel’s aura is deep eggplant purple. When you see sparkles of dark purple light, this is one way to know that Jeremiel is with you. Each archangel has a particular type if crystal aligned with their energy and for Jeremiel, that crystal is the amethyst. When you wear the amethyst, you may feel even closer to Jeremiel’s kind and loving energy.
• Jophiel’s aura is deep rose pink, signifying her beautiful, loving, and caring nature. Dark pink crystals, such as pink rubellite, are associated with Jophiel’s energy. Anytime you’re involved with redecorating or spring cleaning, call upon Jophiel to help you. It’s like having your own spiritual interior decorator and feng shui consultant.
• Metatron’s aura is beautiful violet and sea foam-green stripes. The crystal aligned with Metatron’s energy is watermelon tourmaline.
• Michael’s aura is royal blue mixed with tinges of royal purple. When he’s nearby, you may see cobalt-blue sparkles of light. The crystal stone sugalite is aligned with Archangel Michael’s energy. If you wear a sugalite pendant you may find yourself channeling profound and loving messages from Michael when you speak.
• Raguel has beautiful pale-blue energy, like the sky on a perfect spring morning. He’s the archangel who guides people to act in fair and just ways, and Raguel also gives us faith in humanity’s essential goodness. Wearing or holding an aquamarine crystal will align you with Raguel’s kind and wise persona.
• Ask Raphael to surround anything needing healing with his emerald-green aura. The crystals that are aligned with Raphael’s healing energy are emeralds and malachite.
• Raziel’s aura holds all the colors of the rainbow, like a beautiful prism of light. Working with clear quartz crystals magnifies clairvoyance and helps you feel closer to Raziel.
• Sandalphon’s aura is a calming and cool shade of turquoise, like the translucent tropical ocean. Meditate upon this color, or hold the stone associated with his energy—turquoise—and feel your heart rate and breathing become quieter.
• Uriel’s energy is pale yellow, like a candle’s glow: Whenever you need ideas or intellectual guidance, contact Uriel. His energy is aligned with the amber crystal.
• Zadkiel’s aura is a deep indigo blue. When you wear the mineral lapis lazuli, you may feel a closer connection to Zadkiel. Hold this stone above your eyebrows to awaken your ear charkas and to clearly hear the voice of the Divine.
