Aquamarine Cleaning Aquamarines are best cared for by washing them in warm, soapy water: Fill a small basin halfway with warm water and add a few drops of dish soap. Allow your jewelry to soak for a few minutes before cleaning the stone with a soft-bristled toothbrush. Rinse well in cold water and dry completely before placing back in its pouch or storage box. If you want to remove any residue left behind from previous owners, use a soft brush to scrub away any dust particles. You can also use a mild cleaner to help preserve the color of your gemstone. Aquamarines are natural gems that usually have a greenish tint. However, they can also be blue, red, or white. The color depends on how much iron is present in the rock underneath the surface. As well as being used for jewelry, aquamarines were once popular for their decorative value as stained glass. Today, they are used to make beads for necklaces, bracelets, and other accessories. The word "aquamarine" comes from two Latin words: aqua (water) and marinus (sea). Thus, it means "marine water." In mythology, Aquaman was a Atlantean prince who became king after his father's death. He had two hearts which allowed him to survive in water even if his body was drowning.
