Even though emeralds are considered to be very hard and durable gemstones, care must still be taken to keep from damaging them. The emerald is a brilliantly green stone that serves as the birthstone for May. It is commonly used for jewelry and has been popular since as early as around 2000 BC. Proper care for rough emeralds is imperative to keep these gemstones in their peak condition. Fortunately cleaning them is very simple.
Fill a bowl or basin with warm soapy water. Use a mild dish soap or Woolite.
Gently place the rough emeralds in the water.
Allow the emeralds to soak for 5 to 10 minutes.
Scrub the emeralds with an old toothbrush to remove any loose dirt or debris.
Rinse the emeralds in warm clean water and pat them dry with a clean dry cloth.
