No. Soluble salts, gypsum, unstable sulfides, porous and treated stones, organic gems, delicate clusters, glued objects, and mixed-mineral specimens may be damaged.

Keep it dry, use a hand air bulb for loose dust, and choose a no-contact symbolic method.

No. Hardness measures scratch resistance. Water safety also depends on solubility, porosity, cleavage, toughness, treatment, matrix, glue, and purpose.

No. The suffix appears in thousands of mineral names and has no universal relationship to water behavior.

Sound untreated quartz commonly tolerates brief lukewarm washing. Avoid soaking crackle quartz, dyed material, fracture-filled stones, glued bases, and matrix specimens with softer minerals.

Solid untreated amethyst usually tolerates brief mild washing. Avoid prolonged heat, strong sunlight, thermal shock, coatings, glue, and delicate clusters.

Solid untreated rose quartz commonly tolerates brief cleaning. Fractures, dye, coatings, assembled jewelry, and matrix can require stricter care.

Most solid untreated pieces tolerate brief lukewarm water and mild soap. Dyed, resin-filled, backed, fractured, or mixed-mineral pieces should not be soaked.

Selenite is gypsum. It is soft and measurably soluble, so water can dull, etch, or weaken the surface. Keep it dry.

Rinsing is unnecessary and can affect the fibrous surface. Use dry low-contact care instead.

No. Halite dissolves readily in water and should be kept dry.

Pyrite is best kept dry. Moisture and oxygen can support oxidation, and salt water adds further risk.

Hematite is iron oxide, not raw iron metal, so the simple statement that it always rusts is inaccurate. Matrix, earthy surfaces, coatings, magnetic composites, associated sulfides, and metal findings can still respond poorly to moisture.

Use dry or localized barely damp care. Malachite is relatively soft, may be porous or treated, and should not be soaked or placed in drinking water.

Azurite should generally remain dry or receive only highly localized moisture on a stable polished surface. Avoid immersion, acids, and drinking-water contact.

Some stabilized turquoise jewelry tolerates gentle mild washing, but porous, dyed, waxed, or untreated material can change. Avoid soaking and harsh products.

Chrysocolla-rich material is often porous, mixed, stabilized, or difficult to identify precisely. Keep it dry or use localized damp care.

Soaking is not recommended because mica cleaves and can flake, while rough material may contain several associated minerals. Keep it out of drinking water.

A brief rinse does not create a concentrated lithium preparation. The practical concerns are cleavage, flaking, intergrowths, treatment, and uncontrolled drinking-water use.

A brief localized damp cleaning may be possible, but soaking and forceful rinsing are unnecessary. Fluorite is soft, perfectly cleavable, and vulnerable to thermal shock.

No. Its water solubility is limited under ordinary household conditions. Cleavage, softness, fractures, coatings, and temperature change are usually more important care concerns.

Calcite is not as water-soluble as halite, but it is soft, cleavable, and acid-sensitive. Avoid soaking and use dry or localized damp care.

Sound untreated feldspar commonly tolerates gentle brief washing. Avoid ultrasonic cleaning, steam, strong impact, and rapid temperature change because of cleavage and fractures.

No. Lapis is a mixed rock that can contain calcite, pyrite, dye, wax, and resin. Use a soft cloth or localized damp cleaning.

Prolonged soaking is not a good general practice. Solid, hydrophane, porous, dyed, smoked, doublet, and triplet opals behave differently.

Do not immerse it. Water can enter the layered construction and affect adhesive or backing.

Amber can receive occasional gentle lukewarm damp cleaning, but it should not be soaked or exposed to alcohol, solvents, acids, steam, or heat.

Pearls may be cleaned occasionally with mild lukewarm water, but soaking is unnecessary. Strung pearls must dry completely, and perfume, acids, steam, and ultrasonic cleaning should be avoided.

Only after every mineral, matrix component, coating, and repair is known to tolerate it. A hand air bulb is the safer starting point.

Delicate zeolite sprays and associated matrix are best kept dry. Needles, perfect cleavage, hydration behavior, and attached minerals make rinsing risky.

Solid obsidian generally tolerates water, but sharp edges, coatings, metallic inclusions, glue, and assembled jewelry still require inspection.

Solid moldavite generally tolerates brief water contact, but thin edges can chip and imitation or wire-wrapped pieces may include other materials. It should not be placed in drinking water.

Not as a general method. Salt water can enter pores, damage metal, support corrosion, affect treatment, and leave crystals behind during drying.

Not necessarily. Dry salt can scratch, enter pores and drill holes, attract moisture, and become difficult to remove.

No. It may reduce spotting, but it does not remove solubility, porosity, cleavage, treatment, glue, oxidation, or toxicity concerns.

Hot water is unnecessary and can soften treatments or adhesives and increase thermal-shock risk.

Not as a general method. Vinegar attacks carbonates, organic gems, metals, settings, treatments, and many associated minerals.

Strong bleach and oxidizers can alter color, attack treatments and metal, weaken adhesives, and remove natural surface evidence.

Oils can stain porous stone, enter fractures, soften adhesives, leave residue, and create separate skin or ingestion concerns. Keep fragrance and minerals separate.

Direct bath placement is not recommended for unknown, porous, soluble, metallic, treated, organic, or mixed materials. Place the stone on a dry stable shelf instead.

Pool chemicals, heat, jets, salt, impacts, and prolonged exposure can affect stones, treatments, metals, and adhesives.

Sea water adds salt, sand, microorganisms, impact, loss risk, and legal or environmental concerns. Use a symbolic shoreline practice without immersion.

Keep quartz outside the sealed drinking-water vessel. Chemical durability does not establish food-contact cleanliness or rule out coatings, matrix, polishing residue, or contamination.

Place a sealed container of potable water beside the dry stone. Do not place the mineral in an open inner cup sharing the same water.

No physical contact means the stone is not intentionally dissolving into the water. The arrangement is symbolic rather than a mineral extraction method.

No. Water used to wash a specimen may contain soap, dust, treatment residue, matrix particles, metal, or dissolved material.

Blot gently and allow it to air-dry in shade at room temperature. Avoid direct heat, sun, compressed air, and aggressive rubbing.

Stop cleaning, remove the stone, blot without rubbing, allow controlled drying, and document the affected area. Dye, coating, pigment, or unstable material may be releasing.

Isolate it from other specimens and paper labels, keep it dry, avoid further washing, and arrange appropriate conservation assessment.

Direct sun can heat the object unevenly, fade sensitive color, age resin, and create thermal stress. Dry in shade at room temperature.

Inspect the setting, remove loose grit, use lukewarm water and mild soap only when the stone and construction are compatible, rinse in a bowl, and dry completely.

A loose stone, bead, or entire piece can disappear down the drain, and faucet pressure can worsen an already loose setting.

Use only materials specifically sold and tested for aquarium use. Collector specimens can alter water chemistry, release contaminants, or contain unsuitable matrix and treatments.

Collector specimens may alter pH or release salts, metals, dye, treatment, or residue. Keep them outside the watering container unless the material is specifically intended for horticultural use.

Place the dry stone on a clean cloth beside a sealed glass or bowl of water, take several slow breaths, name one intention, and complete one related practical action.
