Turquoise Jewelry Care: Porous, Soft, and Usually Stabilized

Natural, stabilized, reconstituted

Natural: porous phosphate, color from copper (blue) and iron (green). Oils from skin can shift a sky-blue cab toward green over years. Stabilized: resin pulled into pores under pressure — the usual honest commercial stone. Reconstituted: ground turquoise plus binder, sometimes called block. Dye exists. “Sleeping Beauty” on a $25 earring is often a story.

Stabilization is fine. Lying about it is not. Ask. A 10× loupe showing plastic-looking grain and bubbles is block.

Water and chemistry

Turquoise drinks. Soapy water, chlorine, and perfume sit in pores and in the 0.3 mm gaps of a cheap bezel. A splash is survivable on stabilized material. A hot tub is not. Clean the silver or 14k around it the way you would clean around opal — damp cloth, not a mug soak. If the stone sits in a silver setting that needs a foil bath, take the stone’s welfare first and skip the bath.

• Last on, first off, same as pearls
• No ultrasonic, steam, acetone, or dip
• Store dry, separate, so a 2 mm chain does not grind the 5 Mohs face
• Green shift on skin may be copper chemistry in the stone plus oils, or a brass bezel — different problems

Settings that do not sabotage the stone

A silver or 14k bezel around an 8–12 mm cab is traditional because the rim takes the hit. Glue-in fashion bezels fail in heat. Prongs on a 3 mm-thick cab chip corners. A $90 Kingman (or Kingman-labeled) pendant on a 1.5 mm 14k box chain is a coherent piece. A $18 dyed block on a 0.5 micron plate chain is a season.
