Jewelry Care by Material

Gold Fill
  • Gold-filled jewelry is generally safe to wear in water, except in oceans, pools, and baths. The chemicals in chlorine and saltwater can break down the gold layer over time.
  • Avoid contact with sweat, lotions, perfumes, and cleaning agents to preserve its shine.
  • To clean, gently wipe with a soft jewelry cloth then dry completely.
  • Store in a dry, airtight pouch or box to protect it from moisture and scratches.
Gold Vermeil
  • Gold vermeil is safe for light water exposure but avoid oceans, pools, and baths as the chemicals and salt can wear down the gold plating.
  • Limit contact with perfumes, lotions, and sweat to maintain the thickness and longevity of the gold layer.
  • Clean gently with a soft cloth—avoid abrasive materials or ultrasonic cleaners, which can strip the plating.
  • Store in a dry pouch or box to keep it from tarnishing and scratching.
Sterling Silver
  • Keep sterling silver away from moisture, perfumes, and harsh chemicals to prevent tarnishing.
  • For anti-tarnish coated or rhodium-plated silver, gently clean with a soft jewelry cloth.
  • Surprisingly, wearing your silver jewelry regularly can help prolong its shine—the natural oils from your skin help slow down oxidation.
  • Store in a dry pouch to maintain its brilliance.
9k & 14k Solid Gold
  • Our 9k and 14k solid gold pieces are designed for everyday wear—durable, timeless, and safe for most water conditions.

  • Use a jewelry polishing cloth occasionally for extra shine.
  • Store separately to avoid scratches and maintain their brilliance.
Natural Gemstones

  • Clean with a soft, damp cloth—avoid ultrasonic cleaners, as they can damage certain stones.

Freshwater & Akoya Pearls
  • Pearls are delicate treasures from shells; avoid contact with perfumes, lotions, sweat, and harsh chemicals as they can dull their natural luster.
  • Wipe pearls with a soft, damp cloth periodically to remove residue.
  • Store flat in a soft pouch to prevent scratches.
  • Wearing your pearls often can help maintain their longevity—natural oils from your skin create a protective layer that keeps them hydrated and enhances their shine.

Frequently Asked Questions

What is gold-filled jewelry?
Gold-filled jewelry features a thick layer of 14k or 18k gold pressure-bonded to a brass core. It's more durable than gold-plated and more affordable than solid gold. Our 14k gold-filled pieces contain 5% solid gold by weight; our 18k pieces contain 3% solid gold by weight.
Does gold-filled jewelry tarnish?
Gold-filled jewelry is highly tarnish-resistant thanks to its thick, pressure-bonded gold layer. With proper care, it maintains its shine for years. Avoid contact with sweat, lotions, perfumes, and cleaning agents to preserve the finish long-term.
Can I shower with gold-filled jewelry?
Yes. Gold-filled is generally safe to wear in water, including in the shower. Keep it away from oceans, swimming pools, and baths — the chemicals in chlorine and saltwater can break down the gold layer over time.
Will gold-filled jewelry turn my skin green?
No. Gold-filled is hypoallergenic and safe for sensitive skin. The thick, bonded gold layer prevents the brass core from contacting your skin, making it a reliable option for people with sensitive skin or ears.
How long does gold-filled jewelry last?
With proper care, gold-filled jewelry maintains its shine and finish for many years. Apply perfumes and lotions before putting jewelry on, wipe gently with a soft jewelry cloth after wear, and store each piece in a dry pouch or box to protect it from moisture and scratches.
Is gold-filled the same as gold-plated?
No. Gold-plated jewelry has a very thin gold layer that typically wears off within weeks. Gold-filled has a much thicker gold layer that's pressure-bonded to the core, which is why it lasts significantly longer and doesn't flake, chip, or turn skin green.
