Jewelry Care Guide

Gold Maintenance:

  • Avoid Abrasive Materials: When cleaning your gold jewelry, use a soft cloth or a jewelry polishing cloth to gently wipe away any dirt or smudges. Avoid abrasive materials that might scratch the surface.
  • Avoid Chemical Exposure: Remove your gold jewelry when using household cleaning products, as they might contain chemicals that can tarnish or dull the shine of your jewelry.
  • Storage: Store each piece separately in a soft cloth or a jewelry box to prevent scratching and tangling. Avoid exposure to direct sunlight and extreme temperatures.

Lab Created Diamond Care:

  • Regular Cleaning: To maintain the brilliance of your lab created diamonds, gently clean them with a soft-bristled toothbrush using mild soap and warm water. Rinse thoroughly and pat dry with a soft, lint-free cloth.
  • Routine Inspections: Periodically check the settings of your jewelry to ensure the stones are secure. Loose stones should be taken to a professional jeweler for tightening.

General Tips:

  • Avoid Impact: Remove jewelry when engaging in strenuous activities to prevent damage caused by impact or scratching.

  • Professional Maintenance: Consider professional cleaning and inspection at least once a year to ensure your jewelry remains in optimal condition.

By following these simple guidelines, you can preserve the beauty and shine of your gold and lab created diamond jewelry for years to come.
