Storing and Displaying Your Stone Collection: Safety, Light, Humidity

← Back to Care and safety for stones

How to store, display and label your stones so that they do not scratch, do not fade and pose no danger: sorting by hardness, light, humidity, shelves.

Key points

Golden rule	Hard stones do not sit next to soft stones
Enemies	Direct sunlight, humidity, heat, dust, knocks
Set apart	Selenite, pyrite, pearls, toxic minerals
Labelling	Name, origin, date, known treatment, precautions
Shelves	Sturdy, stable, non-slip, out of reach of small children
Hidden danger	Transparent spheres near a window

Three principles for storing everything

A stone collection, however modest, is best stored according to three simple ideas.

Separate by hardness. A quartz (hardness 7) scratches anything softer. Stored loose together, selenite (2) and amethyst will end up marking each other. See the Mohs scale explained.
Protect from light, humidity and heat. Too much sun fades some colours, too much humidity damages selenite and makes pyrite oxidise, and too much heat cracks opal and amber.
Keep them safe. A heavy piece that falls, a toxic mineral within a child's reach, a sphere that concentrates the sun: these are avoidable accidents.

Storing stone by stone

Stone or object	Where and how to store it
Selenite, angelite, celestine	Dry box or shelf, wedged with foam or paper, away from other stones
Pyrite, hematite, bornite, copper	Dry air, silica gel sachet, away from the bathroom
Amethyst, rose quartz, kunzite	In the shade, away from direct sun
Pearls, mother-of-pearl, coral, amber	Soft fabric pouch (not a sealed plastic bag), somewhere cool, away from perfumes
Opal	Neither near a radiator nor in air that is too dry; a box at a stable temperature
Toxic minerals (raw malachite, stibnite, galena...)	Closed, labelled box, out of reach of children and animals
Tumbled hard stones (quartz, jasper, agate)	A bowl or dish is fine; avoid mixing them with soft stones
Spheres and large transparent crystals	On a stable stand, away from sunny windows

Choosing the right place

Avoid the bathroom and kitchen (steam, humidity), a south-facing windowsill, the space above a radiator and the car dashboard.
Prefer an indoor shelf, a display cabinet or a chest of drawers, in a room with a stable temperature. Fairly dry air suits most stones, especially pyrite; conversely, extreme dryness cracks opal and pearls.
For dust, a soft brush or a dry cloth is enough; a display cabinet or a box limits upkeep.
For weight, check the shelf's load capacity: an amethyst geode or a large cluster of crystals can weigh several kilos.

Boxes, wedges and jewellery

A compartment box, a tray lined with felt or a jewellery case with separate cells prevents rubbing. Wrap each fragile stone in soft fabric or tissue paper. Store jewellery in separate pouches, with chains closed so they do not tangle. For silver, an anti-tarnish sachet or a small silica gel sachet slows darkening. Pearls are best stored flat in fabric: they dislike sealed plastic and very dry air.

For mounted jewellery, see also cleaning stone jewellery.

Labelling and keeping a notebook

A collection is more enjoyable when you know what you own. For each piece, note: the name (distinguishing the trade name from the mineralogical name), the origin if known, the date and place of acquisition, any announced treatments (dyeing, heating) and the precautions. A photo next to a label helps you find a piece and report an anomaly later. If you give a stone as a gift, attach this information.

Safety at home

Children and animals: small tumbled stones and pearls can be swallowed. Large pointed crystals can cut. Keep them out of reach.
Toxic minerals: closed and labelled box; see stones and toxic minerals.
Fire and light: do not place a transparent sphere at a window; never put a candle or an incense burner next to stones resting on fabric or paper.
Earthquakes and falls: place heavy pieces on the lowest shelf, with a non-slip wedge.

Frequently asked questions

Can everything be stored in the same bowl?

Only stones of the same hardness, or very hard ones (quartz, jasper). A hard stone scratches softer stones: keep selenite, fluorite, amber and the like separate.

How do I keep selenite from deteriorating?

Keep it dry, away from the bathroom, on a clean support; do not wash it. Avoid placing it in a damp container.

Should stones be kept out of the light?

Only sensitive stones (amethyst, rose quartz, kunzite, turquoise, opal, amber...). Hard stones such as rock crystal or jasper tolerate daylight.

Where should I put a crystal ball?

On its stand, in a room, well away from the window: a transparent sphere can focus the sun onto fabric or wood.

How do I remove dust from my stones?

With a soft brush or a dry cloth. For stones that tolerate water, a barely damp cloth is enough, followed by drying.
