Crystal Healing

The New Age healing setting

A 2022 review of New Age healing by Jeff Levin traces its emergence into popular culture in the 1980s to interest in human potential and holistic health in the 1960s and 1970s, which in turn drew on Theosophy, New Thought and spiritualism in the nineteenth century. The review lists the therapeutic use of quartz crystals and gems among the practices most popularly identified with the New Age. It is a general study of New Age healing and does not give a dated account of how crystal healing in particular took its present form.

Levin reports that the New Age label has mostly disappeared from popular usage since the 1990s, while associated beliefs and practices have found their way into contemporary medicine and mainline religion in Western settings. He also records three lines of criticism of New Age healing: conservative religious, secular-rationalist and biomedical.

Claims of earlier use

An EBSCO reference entry states that the use of crystals to promote healing and well-being is attested in many traditional cultures, including Egyptian, Indian and Native American cultures, and that traditional and mythological lore about crystals has continued from the Middle Ages to the present. Levin describes crystal healing as one of several techniques popularised since the 1970s that are older than their present context.

Neither source gives dated primary evidence, and neither separates ornamental, ritual, protective and medicinal uses of stones. Continuity between those cultures and the contemporary commercial practice cannot be established from the sources reviewed, and the traditions named should not be treated as interchangeable with one another.

The piezoelectric argument

The EBSCO entry notes that Jacques and Pierre Curie found in 1880 that certain crystals under mechanical pressure produce a measurable electrical charge, called the piezoelectric effect. It reports that proponents cite this finding as scientific support for crystal healing, and states that such explanations are classified as pseudoscience, with no evidence actually supporting the supposed healing properties of crystals.

Names for the practice

The EBSCO entry defines crystal healing as a therapy that employs crystals to effect or facilitate physical, emotional and psychospiritual healing. In everyday use, crystals covers quartz and other gemstones in a wide range of forms, and the entry says that individual examples run into the thousands, grouped into seven structural types.

Stones sold for this purpose are not always the same material as the name suggests, and trials need look-alikes. A 2025 trial used solid glass pebbles as visually matched look-alikes for rose quartz, so its comparison was between a mineral and a similar-looking glass object.

Scholarly labels and energy vocabulary

Researchers place the practice within wider labels. Levin writes of New Age healing, while Tenno Teidearu studies crystal wearing in Estonia as part of New Spirituality, using the frameworks of material culture and vernacular religion. These labels describe how people practise and interpret the use of stones and do not refer to a single organised tradition.

The EBSCO entry states that the supposed mechanism varies by culture, giving the example of an energy system of the body that includes the aura and seven chakras. These are practitioner concepts and are not measured biomedical constructs.

Ways stones are used

The EBSCO entry describes several forms of use: wearing or carrying crystals, temporarily applying a crystal to a person seeking care, placing crystals around a person in a circular pattern, and placing them in view for contemplation. It states that remedies vary from one crystal directory to another and depend on cultural context, tradition and mythology, and on the practitioner's own usage or intuition. No standard directory is recognised across practitioners.

Wearing crystals in everyday life

Teidearu's study of crystal wearing in Estonia reports that people wear crystals to support their human qualities and daily activities, and that the stones come to be described as having a close relationship with their wearers. The study treats crystals as part of the materiality of New Spirituality and notes that wearing them is not an entirely novel trend. Only the abstract and bibliographic record were available for this draft, so participant numbers and methods are not reported here.

Protocols used in studies

Research protocols give some picture of how stones are handled, although they do not describe practitioner-led sessions. In a 2025 trial, participants washed a rose quartz overnight in salt water, dried it each morning and carried it in a wallet or bag for 14 days. A Danish trial asked hospital staff to carry an amethyst in a sealed cloth bag for four weeks, and a 2026 pilot had participants hold a rock crystal for ten minutes while seated.

The sources reviewed do not describe the length, sequence, intake or consent practices of sessions led by a crystal practitioner, or any training standard for practitioners, so no typical session can be described here without going beyond them.

Health claims in reference works

The EBSCO entry lists anxiety, arthritis, back problems, blood pressure and the common cold as principal proposed uses, and a longer set of others, including depression, alcoholism, gastritis, kidney function, skin diseases and vision problems. It gives examples of directory pairings: agate for gastritis and skin diseases, chrysoprase for depression and alcoholism, and jade for kidney function and emotional balance. These are claims recorded by the entry and are not findings.

Meanings reported by users and outcomes studied

Not every use is a health claim. In Teidearu's account, wearers describe stones as supporting personal qualities and daily activities. Of the uses listed in reference works, the sources reviewed include controlled tests of only a few outcomes: anxiety symptoms after carrying a rose quartz, lifestyle factors and self-rated health after carrying an amethyst, and short-term changes in a biophoton imaging measure after holding a rock crystal.

What the searches found

Searches of PubMed and a second academic search service on 5 October 2026 for crystal healing, crystal therapy, lithotherapy, gemstone therapy and healing crystals found no systematic review or meta-analysis of the practice. They found no trial of sessions led by a practitioner, and three small experimental studies of stones, described below. The searches were not exhaustive, and non-English or unindexed work may exist.

Rose quartz and anxiety symptoms

A randomised controlled study published in 2025 enrolled 138 adults from the general population, none reporting a diagnosed mental disorder. Seventy were classed as believers in the healing power of crystals and 68 as nonbelievers, and within each group they received a polished rose quartz or a look-alike glass pebble for 14 days. Anxiety was measured before and after with the Beck Anxiety Inventory and the Spanish Kuwait University Anxiety Scale.

Anxiety scores fell only among believers, whichever stone they held, and no differences between rose quartz and glass were detected. Bayesian estimates favoured no specific effect. The authors concluded that the findings do not support attributing inherent therapeutic value to crystals and that belief and expectancy accounted for the change. Participants had subclinical anxiety, so the result should not be transferred to people with an anxiety disorder.

Amethyst and lifestyle or health ratings

A randomised, double-blind, placebo-controlled trial in a Danish hospital assigned 38 healthcare workers to carry an amethyst or a similar-looking stone for four weeks after Christmas. Questionnaires covered diet, smoking, alcohol, exercise, sleep and self-rated health. Neither group changed measurably, and belief in alternative medicine, reported by 52 per cent, did not alter the outcomes. Drop-out was 18 per cent. The participants were already in good health, which limits what could be detected. This summary rests on the published abstract.

A biophoton imaging pilot

A 2026 pilot reported two experiments with the Bio-Well imaging device. In the first, 120 participants were measured before and after holding a rock crystal for ten minutes, and in the second, 28 women went through baseline, placebo and rock crystal conditions. Statistically significant changes in some indicators followed crystal exposure, but the glass placebo produced similar changes. The authors note that the device is viewed critically for reliability and that factors such as caffeine and sleep were not controlled.

Limits of the studies

The three studies differ in stone, outcome, population and design, and none can be pooled. The rose quartz trial drew on people who had earlier attended an alternative therapies fair and did not experimentally manipulate belief. Its authors also note that participants might have recognised the glass as an imitation. The amethyst trial was small, and its participants were already healthy. The imaging pilot used a measure whose reliability is disputed. None tested practitioner-led sessions, repeated use over months, or people seeking care for a condition.

Placebo, meaning and the difficulty of testing

The EBSCO entry attributes reported effects such as stress relief to placebo responses or to the meditation and mindfulness that often accompany crystal use, and says that the absence of a standard directory makes biomedical testing difficult. The trials above address whether a particular stone adds anything beyond a look-alike. They do not show that people who value the practice have no experience of calm or meaning, and the rose quartz authors suggest that expectancy and therapeutic relationships may amplify placebo responses in clinical settings.

Effects reported in studies and handling risks

The EBSCO entry states that, with some exceptions, there is no obvious risk in wearing or carrying crystals, applying one temporarily to a person or placing stones around them. It names irradiated gemstones, such as some imported blue topaz, as an exception, because repeated or prolonged exposure to their radioactivity could be harmful. The studies reviewed did not present adverse-event analyses, and the amethyst trial was read at abstract level only.

Mineral hazards

A museum-curation paper explains that the hazard of a mineral depends on its chemical composition, solubility and form. It identifies inhalation, ingestion and skin absorption as routes of exposure. Quartz is described as stable but capable of causing silicosis through prolonged exposure to dust from grinding, and some minerals are poisonous and water soluble. Others contain arsenic, mercury, lead or antimony, or are radioactive.

The paper concerns specimens in museum collections, not stones sold for personal use, jewellery or water infused with stones. It does not say which stones in the crystal trade carry these hazards, and its findings should not be read as describing typical risk from wearing a polished stone.

Delayed care, claims and sourcing

The EBSCO entry says that crystal healing has no industry regulation or professional certification, that people may be exposed to scams or fraud, and that relying on it alone could allow a condition to progress when it might otherwise be treated successfully.

The EBSCO entry also notes that sellers rarely state where stones come from and that mining for some stones has been criticised for dangerous working conditions and environmental harm. New, persistent or worsening symptoms, and any emergency, call for assessment by a qualified health professional and should not be routed through a crystal practice.
