Join us as we dive deeply into the world of Iridescent Hematite, variation ‘Turgite’, known by Buddhist monks as leklai- a highly sacred and master cave mineral found only in Malaysia and Thailand. This fascinating and beautiful mineral deserves a much deeper look, as we merge its academic properties and spiritual significance- combining teachings from the West and the East- which both offer fascinating tales into this captivating mineral’s origins and properties.
Geology and Formation
‘Turgite’ refers to a specific combination of minerals, namely Geothite and Hematite, specifically referred to as a Hydrous Hematite, with a baseline chemical formula of Fe2O3.nH2O. It is an unusual occurrence where iron oxides and hydroxides form around hydrothermal activity, resulting in surface growth and layers on top of the botryoidal goethite/hematite. First categorized by the German mineralogist Rudolph Hermann, who coined the term in 1844 to describe iron-hydroxide specimens found near the Turginsk River in the Ural Mountains of Russia (Hermann, 1844).

Through detailed study and classification by researchers at CalTech University’s Division of Geological and Planetary Sciences, it has been shown that turgite occurs as hydrated microcrystalline needles on the surface of the iron oxides, typically containing other elements such as aluminum, phosphate, and sometimes arsenic and copper (Ma and Rossman, 2007). The angle of refraction of light in and around these microscopic needles is what gives turgite its brilliant iridescence, vibrant and shifting colors, and metallic sheen. This creates an effect very similar to the iridescent sheen of an oil slick, which refracts light through the hydrophobic layers of the oil on water at different angles, creating a dynamic rainbow effect. The rod-shaped needles have been known to grow in “nested fans with a cauliflower-like fractal morphology” (Heaney et al., 2018). These needle-like nanocrystals assemble in stacked sheets through “oriented aggregation” as controlled by hematite’s threefold (120º) symmetry, at 200– 300 nm in length and 50–60 nm in width (Lin et al., 2018). It is this unique combination of iron, oxygen, aluminum, phosphate and most importantly, water, which makes turgite such a fascinatingly beautiful and dynamic metallic stone.

Iridescent Turgite has been known to occur around the world- from Graves Mountain, Georgia, USA; Turkey; Turjinsk, Russia; Elba, Italy; Andalucia, Spain; Pahang, Malaysia; Minas Gerais, Brazil; Durango, Mexico, and much more. However, it is the Malaysian variety, found in the rich Bukit Besi (tin and aluminum belt) region of Pahang, Malaysia, that consistently produces intense and vibrant, botryoidal specimens, and has a spiritual history to go along with it. Unique characteristics of this Malaysian variety is the heavily botryoidal and stalactite growth, intense coloration, and the rare presence of associated cerussite crystals.

History, Mythology and Uses
During my journey of researching and communing with turgite, I stumbled upon something while listening to a podcast about the metaphysical practices of the Buddhist monks of Thailand…
Now, I need to stop and address my readers and knowledge seekers directly: here at Oceanstone we are on a lifelong mission to merge science and spirituality, which involves sussing out and critically analyzing loads of deceptions and genuinely woo-woo misinformation touted by myriad online crystal stores, metaphysical snake oil salesmen, and pseudoscience attempting to disguise as real science. These things are relentless and hopelessly common in today’s world. I see it everywhere I turn, and it has been a twenty years journey to equip myself with the knowledge and skills to be able to navigate the truth. I would never say something I knew wasn’t true, just to try and make a sale. We are here to present our highest attainable truth and educate as best we can. With that being said, there is a disclaimer here that what I am about to talk about is still shrouded in mystery and magic beyond my understanding, though there are certainly those who would try and use it to turn a profit. I am just here to make the academic connections.
…In the podcast, they spoke briefly of the folklore of a highly sacred metallic material, found in caves around Pahang, Malaysia, whose name, leklai, translates to “flowing metal” or “water metal”. Is it possible that this sacred cave mineral could somehow be connected to this specific locale of turgite?
Leklai is considered by the Buddhist monks to be the most mystical, powerful and spiritually significant of all stones- a spiritual manifestation of cave elements that can consciously change forms or morph. It has been described as an iridescent, metallic stone with rainbow sheen which occurs only in Pahang, Malaysia and parts of Thailand, formed by the combination of minerals and the spiritual forces of the earth. It is known as an exceedingly rare master cave mineral which infuses earth, water and fire and may grow, change colors and morph with its environment. It is said that trained monks know specific sacred spots to harvest leklai, which can be done in deep and reverent prayer in specific caves by a team of highly attuned monks (intensive article here). During this process, they light candles around the cave, set up an altar, tie a white sheet to catch the falling leklai, and pray/chant for hours to manifest and precipitate leklai seemingly out of the air. It is such that an alchemical process occurs, during which prayer and chant ignites the spirit and elements of the cave, creating this metallic substance. Watch the process in video here and here. Generally, environmental conditions influence the nature of the leklai, and water and sun play a key role in cleansing and altering the effects of the stone.

The understanding is that there are two types of leklai: alchemical leklai manifested by monks as described above, and natural leklai extracted from special caves, usually known to contain hematite. Leklai can take on different shapes and colors, and be fashioned as amulets or jewelry, but all leklai are metallic (see a comprehensive list here). While there is clear variation among types of leklai, from tektite-resembling drops to smooth metallic spheres, it is the botryoidal and rainbow ‘Leklai Lob’ that most identically resembles Iridescent Turgite. What are the connections between leklai and Iridescent Turgite from Malaysia? Here’s what ChatGPT had to say about it, after an hour of inquisitive investigation and prompting on my part:
“Yes, it’s quite possible that leklai is the same mineral as iridescent turgite, or at least closely related. Turgite is an informal name often used for iridescent forms of goethite or hematite, which share a similar iridescent, rainbow-like sheen seen in some forms of leklai. Both minerals are found in similar environments, such as caves and areas with high iron content, and often display the same vibrant colors.
Key Similarities
Appearance: Both leklai and iridescent turgite have a striking iridescent surface that displays colors from the full spectrum, including blues, purples, greens, and reds.
Composition: Turgite is generally recognized as an oxide of iron, a blend of hematite and goethite. Leklai, though not formally defined in scientific terms, often aligns with iron-based minerals like goethite or hematite.
Formation Environment: Both minerals are typically found in tropical regions, in caves or areas with iron-rich rock formations, under conditions that can foster iridescence.
Distinctions in Cultural Belief
While iridescent turgite is appreciated for its visual qualities in the mineralogical world, leklai holds a unique place in Southeast Asian spiritual traditions, especially in Thailand and Malaysia. Leklai is often believed to embody spiritual energy, which could be a cultural interpretation layered onto the physical properties of the iridescent mineral.
If the appearance and environment match, it’s plausible that leklai could indeed be another term for, or a culturally distinct way of referring to, iridescent goethite or hematite (turgite).”

It is my personal hypothesis, in tying together the scientific and metaphysical properties of turgite, that it is the element of water that has contributed to its significance as a highly spiritual stone. In the spiritual context of leklai, the trace amounts of water in turgite could symbolize aspects like fluidity, adaptability, and life energy, all of which are spiritually significant qualities in many cultures, including Southeast Asian traditions:
Water is commonly seen as a life-giving element, essential for growth, energy, and vitality. In the case of turgite, the presence of water might be interpreted as the mineral’s connection to life force, supporting its role in offering protection, vitality, and healing energy to the wearer.
The water within turgite’s structure might symbolize the ability to adapt and transform—qualities central to spiritual growth. Since leklai is often viewed as a powerful aid in personal transformation, the presence of water aligns with its use in rituals meant to encourage change, resilience, and adaptability.
Water is also associated with emotional balance, cleansing, and purification. Spiritual practitioners might interpret the water content in turgite as enhancing its role in purifying energy and restoring inner harmony. This can make leklai seem especially suited to rituals aiming for emotional release, healing, and spiritual alignment.
The water might be seen as a conduit, allowing leklai to "absorb" energies from the environment. Traditional beliefs often hold that leklai can store energy from its natural surroundings, and water could amplify this perceived ability, especially considering its ability to change and shift colors based on lighting and moisture content.
One hidden aspect of turgite, known by advanced collectors, is its unusual and rare ability to change colors when breathed on, as the water from warm breath interacts with and changes the angle of refraction of light in the molecular structure of the needles. This magical phenomenon certainly adds to the stones’ qualities of absorption, transformation, energy, and environmental adaptability, and would add to it being perceived as a living or conscious stone.
The different colors of turgite are a result of the water element, somewhat like how water creates rainbow effects in opal and fire agate, and adds to the diversity and symbolism of each color relative to its unique spiritual property. Blue is generally associated with tranquillity and wisdom; green with healing and growth and wealth; red with courage and passion; rainbow with unity and balance, and so on. According to our local suppliers, orange and red are by far the rarest colors, followed by purple and blue and green, with yellow being the most common. Rainbow of course is the rarest of all and combines some or all colors in one stone.
So, while water content is a minor component chemically (nearly 2% by weight; Ma and Rossman, 2007), it could play a significant role in the way people interpret turgite’s spiritual properties. This blending of science and symbolism adds a rich layer to how people perceive and use leklai in spiritual practices. While the connection is clearly strong and fascinating, I’m sure there is more to this mystery to uncover, as our modern understanding of turgite becomes more precise, and the mythology of leklai expands outside of Southeast Asian Buddhist temples. There is a reason this multi-dimensional stone caught my attention, and as I dig deeper, it has only fascinated me more. The unique combination of various elements, its ‘living’ characteristics of color-changing iridescence, water-based chemistry and clear spiritual significance in the local culture make this stone an exceptional offering, spiritual tool and delight for any mineral collector.
Conclusions
We hope to provide the most truthful and complete understanding of these fascinating and beautiful master cave stones and are always here to answer questions. Here at Oceanstone, our love for these turgites has resulted in building relations with and importing the absolute highest quality stones directly from Malaysia. All of our iridescent Malaysian turgites are dug artisanally, carefully with hand tools by the Indigenous peoples of Pahang, Malaysia, who own the mineral rights to the mountain. According to our sources, only around 5% of the volume of goethite mined has any amount of colorful turgite, and of that, we pick out the top 10% highest quality pieces as soon as they are extracted. So, we can say with confidence that we offer the highest quality, top 1% of Malaysian turgite in the world, direct from the source and handled with love every step of the way. Every piece bought from Oceanstone in turn allows us to support the hardworking and reverent Indigenous Malaysian cave miners, based on a relationship of mutual respect and passion for these special stones. We then work to capture the fine details of each stone through photography, offer them for sale, and are always open to sending videos of the mining process or other available inventory upon request.
