When we create space to heal our spirits – we transform the world.


Kristen Sonntag is a Reiki Master, musician, and writer. Her line of crystal essence and aromatherapy mists, SPIRIT WORK, is a tool to assist in healing work, meditation, and the creative process.

SPIRIT WORK is a ritual mist made with crystal essences in distilled water, pure high-quality essential oils, and Reiki energy, available in four different energetic vibrations: Creator, Ground, Open, and Space. Every bottle comes with a sound and guidebook download.

SPIRIT WORK is handcrafted to order in Brooklyn, NY. Each crystal essence is prepared in small batches, seasonally, in harmony with the moon cycle. Sunday Diamond is committed to the ethical and sustainable sourcing of untreated crystals and high-quality essential oils. Every effort is made to find and use materials responsibly. Packaging is made and printed in the USA.


Kristen’s psychic abilities were activated as a child in Virginia Beach, an area known for its metaphysical energies, where she received her introduction to crystal healing, Tarot, past life memories, and communication with spirit.

The spiritual gateway reopened to her as an adult following a near-death experience after the birth of her son. After training with psychic medium Betsy LeFae, Kristen received her Reiki I attunement in 2015 with Erika Spring and Reiki II in 2016 with Padma Gonzalez, at Maha Rose in Brooklyn, NY. In the spring of 2019 she became a certified Reiki Master in the Usui/Holy Fire III system of healing, studying with William Lee Rand in Glastonbury.

Kristen’s work is informed by the traditions of Western Esotericism and Hermeticism, Tibetan Buddhist philosophy, and matrilineal/earth-based magic. As the sister of a developmentally disabled brother, her activism is focused on advocacy and civil rights for adults with disabilities. Her current studies include healing and integrating past life experiences and ancestral trauma, and fostering compassion and inclusivity through community.

The name Sunday Diamond is a union of names; the English translation of Kristen’s last name and a storied surname on her husband’s side. Kristen is a daughter of the Navy and was born in Honolulu and raised in California and Virginia. She returned to her familial New York roots in 2001. Kristen is also an Emmy-nominated television producer, and a graduate of the University of Virginia, with a BA in Psychology and Studio Art.
