Emeralds are considered the traditional gift for the 55th wedding anniversary. The legendary magnificence of the emerald throughout time has led to it being one of the most popular gemstones in jewelry design.
Emeralds are a relatively hard stone, 7.5 on the Mohs, and are often coated with oil to enhance the clarity.
Care should be exercised when both wearing and cleaning emerald jewelry.
The high internal inclusions found in most emeralds make them very susceptible to sharp blows and sudden temperature changes.
The safest and best way to clean a piece of jewelry containing emeralds is with lukewarm water, a very mild soap and a soft cloth.
