2. Caring for Opal and Tourmaline:
Both opal and tourmaline are relatively softer gemstones compared to diamonds, so
care should be taken to avoid scratches.
Opals contain water and are sensitive to changes in temperature and humidity. It's best
to store them away from direct sunlight and extreme conditions.
Tourmaline is generally more durable but can still be sensitive to heat and certain
chemicals. It's advisable to clean them with mild soap and warm water.
Both opal and tourmaline offer a wide range of colors and variations, making them
popular choices for jewelry. Their unique characteristics and vibrant hues make them
prized additions to any collection.
