Stone, structure, and the way a piece is chosen.
Field notes for understanding BE. materials, comparing stones, choosing size, and caring for what you wear.
A science-first answer to whether crystals are radioactive — which minerals contain uranium or thorium, measured emission levels, and which stones are safe to wear.
An honest scientific assessment of whether crystals affect the human body — the placebo evidence, the physical-property evidence, and what we actually know.
A science-first reframe of crystals as geology — how they form, what they actually do, and why the mineralogy is more interesting than the metaphysics.
How long crystals actually take to form — million-year timescales for quartz, decades for opal, and what time tells you about a mineral.
A geology-first guide to hematoid quartz — quartz with iron oxide inclusions, why colours range from rust to dusky red, top deposits and how to read a strand.
A geology-first guide to emerald phantom quartz — what makes the green colour rare, how the chlorite ghosts form, and how to read a strand.
A geology-first guide to rose quartz — what gives quartz its pink colour, why some pieces show asterism, where the best material forms, and how to read a strand.
A geology-first guide to prehnite — calcium-aluminium silicate formation, why some pieces show epidote needles, top deposits and how to read a strand.
A geology-first guide to clear quartz — its lattice, why some specimens are flawless and others milky, where the best material forms, and how to read a strand.
A geology-first guide to garnet — the garnet group of minerals, why colour varies from red to green, top deposits and how to read a strand.
The chemistry of crystal colour — Fe / Mn / Cr / Cu / Ti trace elements and how each shifts mineral hue across the gem spectrum.
A geology-first guide to obsidian — volcanic glass formation, black/snowflake/rainbow/sheen varieties, top deposits, and how to read a strand.
