Product Care

Cast fine jewelry is designed and crafted with care. To keep your pieces looking their best, we recommend wearing your jewelry often, wiping it with a polishing cloth after each wear, and storing it in its Cast clutch.

Please follow the care instructions for the metals, gemstones, and materials used in your piece.

Metals & Materials

Gold, Silver, and two-tone products - without stones 

Precious metals, both gold, and silver, will tarnish in the natural environment. Tarnishing is the result of metals present in the alloy, mostly copper, reacting to the environment, particularly sulfur compounds in the air. Salty air, chlorine, humidity perspiration, cosmetics, bleach, and strong chemicals will accelerate this reaction causing a discoloration of the metal surface.

CARE TIPS

  • Avoid saltwater and chlorinated water.
  • Avoid exposure to harsh chemicals.
  • Minor metal surface abrasion, scratches, and dents can be the result of impact against hard surfaces during normal wear. Having your jewelry professionally cleaned from time to time (annually) will help in keeping your jewelry looking its best.
  • Clean your jewelry at the first sign of tarnishing by soaking it in warm water and a few drops of mild dish soap. Hand wash with a soft cloth and a soft-bristle brush and rinse under warm water. Dry by patting them with a clean, soft cotton cloth.

Ceramic and HyCeram

Ceramic boasts a hardness that is unlike any traditional metal used in jewelry. It is considered to be scratch proof and will not show signs of wearing, even after years. Ceramic is also unaffected by the ultraviolet rays produced by the sun, meaning that its colors won’t fade.

While ceramic and HyCeram are extremely durable and can resist scratches and common damages, due to the molecular structure they are not resistant to shattering.

CARE TIPS

  • Protect your jewelry from an impact on hard surfaces.
  • Follow the same cleaning instructions as gold and silver jewelry.

Enamel

CARE TIPS

  • To maintain enamel’s luster, avoid exposure to extreme temperature, lotions, cosmetics, acetone, and harsh chemicals.
  • Follow the same cleaning instructions as gold and silver Jewelry.

Opaque Gemstones

Opaque gemstones - such as lapis, turquoise, malachite, and opals - tend to be  softer, more porous and easily absorb unwanted chemicals and foreign materials in the environment. Dirt and oils can build up and damage the polish or discolor the stone. It is important to properly care for and maintain your gemstone jewelry. 

CARE TIPS

  • Colored stones can chip, scratch and break. Protect your jewelry from an impact on hard surfaces. 
  • Do not wear while doing exercise or yard work.
  • Do not wear in a swimming pool.
  • Avoid harsh chemicals including bleach, ammonia, chlorine, and many household cleaning products.
  • Avoid fragrances, lotions, and cosmetics coming into direct contact with the stone. 
  • Never use an ultrasonic cleaner or steam clean.
  • Never soak for an extended period in hot water.
  • To clean, dip in warm water with a mild dish soap (do not soak). Wipe down stone with a clean cotton cloth. Use with a clean, soft cotton cloth to dry.

Translucent Gemstones

Transparent -to-translucent gemstones, such as blue topaz, citrine, amethyst and iolite can develop a dirty film on the exterior, making them appear dull.

CARE TIPS

  • Colored stones can chip, scratch and break. Protect your jewelry from an impact on hard surfaces.
  • Follow the same cleaning instructions as gold and silver jewelry.

Pearls

CARE TIPS

  • Wearing pearls regularly will help maintain their natural beauty and luster. Wipe down the pears with a very soft clean cloth after wearing.
  • Avoid exposure to fragrances, cosmetics, lotions and hairspray.
  • Avoid ammonia and other harsh chemicals.
  • Do not wear while exercising as perspiration should be avoided.
  • Never use ultrasonic cleaning or steam clean.
  • Wash pearls from time to time in a solution of warm water and mild, non-abrasive soap. Rinse, and pat dry with a soft cloth. Pearls like moisture so no need to thoroughly dry. However, if your pearls are strung make sure the string is dry before wearing.
  • Check stringing for security often and have restrung every one to two years if worn often.

Metal Prongs, Clasps and Mechanisms

Precious metals do wear over time. Cast engineers test all pieces to ensure durability. However, when a piece is constantly used, metal fatigue can occur.

CARE TIPS

  • Check your mechanisms regularly. Make sure that when the clasps and bales are engaged, there is a firm and reliable connection. If you notice fatigue, send the piece in for repair. Cast will build up the metal to ensure security.
  • Prongs also wear over time. Regularly check that your prongs are adequately securing diamonds and colored stones. If you notice vulnerability, send the piece in for repair. Cast will build up the metal and ensure the stones are set securely.
