How to care for Gold Sheen Obsidian jewellery

Direct answer. Wear in low-impact rotation. It scratches more easily than quartz, aquamarine and garnet, and a hard knock can chip an edge or drill hole.

Mohs / exterior5 to 5.5
Toughness / cleavageBrittle glass; no mineral cleavage
Ordinary daylightSUITABLE
High heat / sudden changeREMOVE
Care boundaries

Water and hand cleaning

Use a soft dry cloth. If needed, use a brief barely damp mild-soap wipe, then dry the bead holes and clasp completely. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

Ordinary daylight is reasonable. Keep it out of long, intense sun. Do not leave the object to accumulate heat on a windowsill or dashboard.

Heat and temperature change

Volcanic glass is brittle and moderately heat-sensitive. Avoid high heat and abrupt temperature change.

Impact, abrasion and stacking

Remove before sport, weights, gardening, manual work or contact with stone, metal and concrete.

Ultrasonic and steam

Avoid. Hidden fractures in brittle glass may chip under vibration. Avoid heat and thermal stress.

Current product construction

Steel wire + round magnetic clasp. Open it at the round magnetic clasp; do not pull the beads or wire. Keep the complete strand out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam. Clean with a dry or barely damp cloth, dry the clasp seam and bead holes, then store flat or in a relaxed curve.

Earlier elastic edition

Roll the bracelet over the hand without pulling individual beads or stretching the loop wide. Keep it out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam. Store it flat, dry and unstretched; stop wearing it if the cord whitens, frays, loosens or remains elongated.

Storage and travel

Store alone in a padded pouch; do not stack against harder beads or a watch.

Identification boundary

A fresh obsidian fracture can be sharp. Stop wearing a chipped bead until it is inspected.

Evidence boundary. The weakest relevant component (stone, drill edge, wire or elastic, and clasp) sets the finished object's verdict.

Care boundaries

Water and hand cleaning

Warm soapy water is safe for an intact bare stone. Wipe the assembled strand; do not immerse it. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

Brief ordinary daylight is compatible with normal wear. Some amethyst colour can fade after repeated prolonged intense light. Normal outdoor wear is fine. Keep it off sunny windowsills and dashboards, and out of all-day beach sun.

Heat and temperature change

Do not subject amethyst to heat; abrupt temperature change can create fractures. No sauna, hot tub, steam or hot-air drying.

Impact, abrasion and stacking

Good toughness is not impact-proof. Remove it for weights, gardening, sport and hands-on work.

Ultrasonic and steam

A verified untreated, unfilled and unfractured loose stone is usually compatible. The complete drilled-bead strand is not. Steam cleaning is not recommended.

Current product construction

Stainless-steel wire core + round magnetic clasp. Open it at the round magnetic clasp; do not pull the beads or wire. Keep the complete strand out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam. Clean with a dry or barely damp cloth, dry the clasp seam and bead holes, then store flat or in a relaxed curve.

Earlier elastic edition

Storage and travel

Store dry, separately and away from prolonged strong light.

Identification boundary

Long, strong light is what fades amethyst; ordinary daylight wear is fine.

Evidence boundary. Product-level fracture and treatment status controls machine-cleaning safety. The weakest relevant component (stone, drill edge, wire or elastic, and clasp) sets the finished object's verdict.

Water and hand cleaning

Warm soapy water is safe for an intact bare stone. Wipe the assembled strand; do not soak it. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

Ordinary daylight is compatible with normal use. Some citrine colour may fade after prolonged intense light. Do not make a sunny windowsill, hot car or repeated all-day beach exposure routine.

Heat and temperature change

Abrupt temperature change can fracture citrine and heat may alter colour.

Impact, abrasion and stacking

The quartz surface resists ordinary scratches, but drill edges and existing fractures can still chip.

Ultrasonic and steam

Usually safe only for an untreated and unfractured loose stone. Avoid for the finished strand. Steam is risky because citrine should not be subjected to heat.

Current product construction

Stainless-steel wire core + round magnetic clasp. Open it at the round magnetic clasp; do not pull the beads or wire.

How to care for Smoky Quartz jewellery

Direct answer. Suitable for regular low-impact wear. This verdict applies to finished jewellery: Mohs 7 describes scratch resistance, but it does not override existing fractures, drilled bead edges, wire or elastic, and clasp limits.

Mohs / exterior7

Care boundaries

Water and hand cleaning

Brief lukewarm mild-soap cleaning suits an intact untreated bare stone; wipe the assembled strand. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

Some smoky quartz can pale after prolonged UV exposure. Ordinary daylight wear is reasonable; avoid long display exposure and do not let the finished strand heat on a windowsill or dashboard.

Heat and temperature change

High heat can anneal smoky colour centres and lighten or alter the brown. Abrupt temperature change can also stress existing fractures and drilled bead edges; remove the finished strand before saunas, steam, hot-car exposure or rapid cooling.

Impact, abrasion and stacking

Remove for rough work, weights and impact; quartz hardness does not prevent chipping.

Ultrasonic and steam

Loose-stone guidance does not authorise machine-cleaning assembled jewellery. For a BE. wire or elastic strand, avoid ultrasonic and steam cleaning: vibration and heat can stress fractures and drill edges and can affect the clasp or stringing.

Current product construction

Stainless-steel wire core + round magnetic clasp. Open it at the round magnetic clasp; do not pull the beads or wire. Keep the complete strand out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam.

Water and hand cleaning

Warm soapy water is safe for the bare stone. Wipe the complete strand; do not immerse it. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

GIA describes rose quartz as generally stable to light. The stone is generally light-stable, but the finished piece should not be left to accumulate heat on a dashboard or sunny sill.

Water and hand cleaning

Brief lukewarm mild-soap cleaning is appropriate for an intact untreated bare stone; wipe the complete strand. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

Untreated colourless quartz has no colour-fade concern relevant to its appearance. Light itself does not remove a colour that is absent, but this scenario also includes heat accumulation in a hot car or on a sunny sill.

Heat and temperature change

Avoid high heat and abrupt temperature change, especially when fractures or liquid inclusions are visible.

Impact, abrasion and stacking

Good scratch resistance does not stop a drilled edge from chipping under a hard blow.

Ultrasonic and steam

Only conditionally compatible when untreated and free of significant fractures. Avoid for the assembled bracelet. Avoid steam; heat can stress fractures and inclusions.

Care boundaries

Water and hand cleaning

Use a dry cloth first, then a barely damp wipe only if needed. Never immerse the elastic strand. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

Ordinary indoor and passing daylight wear is fine. Avoid prolonged intense sun.

Heat and temperature change

Avoid high heat and abrupt temperature change.

Impact, abrasion and stacking

Quartz host gives useful scratch resistance, but elastic, drill edges and internal fractures remain limits.

Ultrasonic and steam

Never machine-clean the complete elastic strand.

Current product construction

Reinforced elastic cord. Roll the bracelet over the hand without pulling individual beads or stretching the loop wide. Keep it out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam. Store it flat, dry and unstretched; stop wearing it if the cord whitens, frays, loosens or remains elongated.

Storage and travel

Store flat, dry and unstretched. Inspect for whitening, fraying or permanent elongation.

Identification boundary

BE.'s current lot record attributes the blue appearance to Tyndall scattering from a submicroscopic-particle haze.

Evidence boundary. The weakest relevant component (stone, drill edge, wire or elastic, and clasp) sets the finished object's verdict.

Care boundaries

Water and hand cleaning

Use a brief lukewarm mild-soap wipe; no soaking; dry holes and fractures fully. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

Ordinary indoor and daylight wear is fine. Avoid prolonged intense sun.

Heat and temperature change

Avoid high heat and thermal shock.

Impact, abrasion and stacking

Inspect each bead; toughness varies from bead to bead.

Ultrasonic and steam

Avoid ultrasonic cleaning; inclusions and fractures vary from bead to bead. Avoid steam; heat can stress the inclusions.

Current product construction

Steel wire + round magnetic clasp. Open it at the round magnetic clasp; do not pull the beads or wire. Keep the complete strand out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam. Clean with a dry or barely damp cloth, dry the clasp seam and bead holes, then store flat or in a relaxed curve.

Earlier elastic edition

Roll the bracelet over the hand without pulling individual beads or stretching the loop wide. Keep it out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam. Store it flat, dry and unstretched; stop wearing it if the cord whitens, frays, loosens or remains elongated.

Storage and travel

Store alone and padded.

Identification boundary

A fixed seven-mineral composition must not be presented as fact.

Care boundaries

Water and hand cleaning

Use warm water, mild detergent and a soft brush; clean briefly and gently, then dry. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

Ordinary indoor and daylight use is fine. Avoid prolonged heat accumulation.

Heat and temperature change

Cleavage and common inclusions increase fracture risk under high heat or abrupt temperature change.

Impact, abrasion and stacking

It can scratch more easily in another direction and split along cleavage. Remove for manual work and sport.

Ultrasonic and steam

Mechanical cleaning is not recommended. Avoid heat and cleavage stress.

Current product construction

Stainless-steel wire core + round magnetic clasp. Open it at the round magnetic clasp; do not pull the beads or wire. Keep the complete strand out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam. Clean with a dry or barely damp cloth, dry the clasp seam and bead holes, then store flat or in a relaxed curve.

Earlier elastic edition

Roll the bracelet over the hand without pulling individual beads or stretching the loop wide. Keep it out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam. Store it flat, dry and unstretched; stop wearing it if the cord whitens, frays, loosens or remains elongated.

Storage and travel

Store separately in a padded compartment.

Identification boundary

Directional hardness is the central care fact: resistance changes with crystal direction.

Evidence boundary. Inclusion and fracture density remain specimen-specific. The weakest relevant component (stone, drill edge, wire or elastic, and clasp) sets the finished object's verdict.

How to care for Almandine Garnet jewellery

Direct answer. Suitable for regular and long low-impact wear. Garnet has fair-to-good toughness, but daily does not mean sleep, sport, weights, gardening or 24/7 wear.

Mohs / exterior7 to 7.5
Toughness / cleavageFair-to-good jewellery toughness; no true cleavage
Ordinary daylightSUITABLE
High heat / sudden changeLIMIT
Care boundaries

Water and hand cleaning

Warm soapy water is always a safe choice for the bare stone. Wipe the finished strand; do not soak it. A bare-stone cleaning method is not permission to wear the complete bracelet in water.

Sun and ordinary light

Garnet is stable to light. Ordinary and longer outdoor daylight are not the amethyst-style fading concern. Garnet is stable to light. The limit in this combined scenario is heat accumulation and the finished strand.

Heat and temperature change

Avoid unnecessary high heat; abrupt temperature change may cause fractures.

Impact, abrasion and stacking

Fair-to-good toughness is durable. A hard knock can still chip a bead. Remove for gardening, weights, contact sport and hard surfaces.

Ultrasonic and steam

Usually safe only for a loose stone without fractures or filling. The complete strand remains excluded. Steam cleaning is not recommended.

Current product construction

Stainless-steel wire core + round magnetic clasp. Open it at the round magnetic clasp; do not pull the beads or wire. Keep the complete strand out of showers, baths, pools, sea water, saunas, hot tubs, ultrasonic cleaners and steam. Clean with a dry or barely damp cloth, dry the clasp seam and bead holes, then store flat or in a relaxed curve.

Storage and travel

Store clean, dry and separate; garnet can scratch moonstone.

Identification boundary

Garnet is a mineral group. For the specific garnet identity and treatment disclosure, refer to the individual BE. product page. Do not apply almandine's 7 to 7.5 range to every garnet.

Evidence boundary. Fracture and filling status still control machine-cleaning safety. The weakest relevant component (stone, drill edge, wire or elastic, and clasp) sets the finished object's verdict.

Tiger’s EyeReviewed 3 October 2026

How to care for Tiger’s Eye jewellery

Direct answer. Wear for a low-impact day. Clean gently by hand and put the bracelet away before water, rough work or heat.

Mohs hardness7

High heat / sudden changeREMOVE
Care boundaries

Water and hand cleaning

Wipe with a soft cloth. For residue, use a barely damp cloth with a little mild soap, then remove the soap with a clean damp cloth and dry. For the assembled bracelet, remove before showering, bathing or swimming. After a splash, blot the bead holes and fastening and let the piece dry before storing.

Sun and ordinary light

Ordinary daylight is reasonable. If dyed, prolonged sunlight may affect the colour. Keep the piece off sunny windowsills and out of hot cars.

Heat and temperature change

Avoid saunas, hot tubs and steam cleaning. Let a warm piece return to room temperature naturally; do not plunge it into cold water.

Impact, abrasion and stacking

Take it off for weights, sport and manual work. Hardness describes resistance to scratching; drilled beads can still chip. Keep a gap between the bracelet and a watch or another strand.

Perfume, cleaners and treatments

Put the bracelet on after cosmetics have dried. If dyed, alcohol or acetone may affect the colour. Avoid these solvents and household cleaners. Do not use a solvent to test whether a bead is dyed.

Ultrasonic and steam

BE. recommends hand cleaning for this complete bracelet. Any treatment, existing damage and the fastening must be considered before professional cleaning.

If your piece has a magnetic clasp

Open at the clasp without pulling the beads. Check that it closes securely. Dry the seam after accidental wetting; store with the wire in a relaxed curve. Stop wearing it if a fitting loosens or the wire kinks.

If your piece has elastic cord

Roll it gently over your hand without pulling individual beads. Store flat with the cord relaxed. If it frays, loosens or stays stretched, set the bracelet aside for repair.

Storage and travel

Use its own soft pouch or padded compartment. Put it away dry; leave it off overnight. Before wearing it again, check for a new chip, crack or damaged drill edge.

Material and treatment

Tiger’s Eye is a quartz gem. GIA lists hardness 7, good toughness and possible heat, dye or bleach treatments. Avoid abrupt temperature changes.

Your piece. Choose the fastening that matches your bracelet. Treatment information is material-level guidance; it does not identify the treatment of an individual BE. piece.
