KnowMastery The stones traditionally worked with at the crown chakra, at the top of the head.
The crown is the seventh and highest centre in the scheme, at the top of the head, and it is associated with perspective, meaning and the sense of being part of something larger. Its stones are the clears, whites and violets, and they are the ones used to end a practice rather than to start one, after the lower centres have been settled.
Chrysoberyl
Green in daylight and red under lamplight, which is why it became the stone of the two-sided life.
Worth knowing: Genuine alexandrite is rarer than diamond. Nearly everything sold under the name is lab-grown alexandrite or colour-change synthetic corundum.
Quartz · Mohs 7
The purple quartz people reach for first, kept by the bed for a quieter head at night.
Phyllosilicate
Glassy clear pyramids that grow on basalt, kept for the sense of a room being aired out.
Phosphate inclusion
Golden needles growing inside amethyst or quartz, sold as a stone of large-scale change.
Worth knowing: Cacoxenite is an inclusion rather than a standalone crystal. What is sold as cacoxenite is host quartz or amethyst with the mineral growing inside it.
Sulfate · Mohs 3–3.5
Pale sky-blue crystals, tied to a very quiet kind of stillness.
Quartz
Doubly terminated quartz from Herkimer County, New York, so clear it was mistaken for diamond.
Worth knowing: A Herkimer diamond is quartz, not diamond. It sits at 7 on the Mohs scale rather than 10.
Mica · Mohs 2.5–3
Lilac mica that genuinely contains lithium, and traditionally the anxiety stone.
Nacre (organic)
The iridescent lining of a shell, worn as a protective and motherly charm in coastal cultures.
Worth knowing: Mother of pearl is organic, made of aragonite platelets laid down by a mollusc. Acids, perfume and vinegar etch it.
Glass
Milky and blue-glowing against the light, popular for transitions and for how it looks.
Worth knowing: Opalite is man-made opalescent glass. It is not opal, not moonstone and not a mineral, and honest sellers say so.
Gypsum · Mohs 2
Translucent white gypsum, used to clear rather than to add. It dissolves in water.
Cyclosilicate
Deep magenta-purple, only identified in 1944, and traditionally given to people who absorb the mood of a room.
Anhydrite · Mohs 3–3.5
Chalky blue anhydrite, associated with comfort and a sense of company.
Quartz · Mohs 7
The blank stone. It holds no agenda of its own, which is why it is used to strengthen whatever sits beside it.
Borate · Mohs 3.5
Chalk-white with grey veining, and traditionally the patience stone.
Worth knowing: Dyed howlite is the most common turquoise substitute on the market. If a blue stone is cheap, evenly coloured and scratches easily, this is usually what it is.
Tektite glass · Mohs 5.5
Green glass formed by a meteorite impact, with a reputation for rearranging lives fast.
Worth knowing: Moldavite is a tektite, glass formed by a meteorite impact about 15 million years ago, and it is one of the most faked stones sold. Green bottle glass is the usual substitute.
Feldspar · Mohs 6–6.5
White with a floating sheen, linked to cycles, patience and your own timing.
The traditional practice is simple and physical: one stone, placed at the top of the head or held in the hand, for as long as it takes to notice your breathing change. Tradition treats more stones as less effect rather than more, and the usual advice is to finish at a lower centre than you started so you do not get up light-headed. If you are new to the scheme, the full guide to the seven chakras explains what each centre is said to govern.
The mineral family, the Mohs hardness and the water verdict on each card are checkable physical fact, drawn from standard mineralogical and gemmological references. The chakra, element and purpose associations are tradition, published across the modern crystal-healing literature and offered here for reflection rather than as fact.
