Multicolor lapis lazuli, with its striking deep blue hue and inclusions of pyrite (golden flecks) and calcite (white streaks), is a beautiful and unique gemstone that requires thoughtful care due to its specific characteristics. Here's how to ensure your multicolor lapis lazuli jewelry remains vibrant and well-preserved:

Understanding lapis lazuli's properties
• Lapis lazuli is a composite rock, not a single mineral, and is primarily composed of lazurite, calcite, and pyrite.
It has a Mohs hardness of 5 to 5.5, meaning it's relatively soft and can be easily scratched by harder materials.
• Lapis lazuli is porous and can be dyed to enhance its color, making it sensitive to certain cleaning agents and prolonged exposure to water.
• The calcite inclusions within lapis lazuli can dissolve with prolonged exposure to water, potentially leaving small holes.
• Pyrite inclusions can release toxins, like sulfur, when in contact with water, potentially causing skin irritation, according to the Planderful Shop.
• Lapis lazuli can be treated with wax or oil to improve its luster, and these treatments have fair stability but can be affected by heat or solvents.

Cleaning multicolor lapis lazuli
Avoid harsh chemicals:
• Never use harsh chemicals, bleach, ammonia, or abrasive substances like toothbrushes or cleaning pads as they can damage the stone, according to MOONIQUE creation.
Gentle cleaning is key:
• The safest way to clean lapis lazuli is with warm, soapy water and a soft cloth, recommends GIA.
• Wipe, rinse, and dry: Gently wipe the jewelry with a soft, damp cloth. You can use a mild soap solution, but be sure to rinse it well and dry it thoroughly with a soft, dry cloth.
Avoid soaking:
• Do not soak lapis lazuli in water as it's porous and can absorb moisture, leading to discoloration or damage over time. If you must remove dirt quickly, use a quick rinse with warm water and dry it immediately with a soft cloth.
No ultrasonic or steam cleaners:
• Avoid these as they can damage the stone.

Wearing lapis lazuli jewelry
Put it on last:
• Apply cosmetics, perfume, hairspray, and lotion before putting on your lapis lazuli jewelry, according to MOONIQUE creation.
Keep it dry:
• Avoid wearing lapis lazuli in the shower, while swimming, or during activities that involve prolonged exposure to water.
Handle gently:
• Avoid dropping the jewelry onto hard surfaces as lapis lazuli can chip or break.
Avoid chemicals and harsh impacts:
• Remove lapis lazuli jewelry before engaging in physical activities or household tasks to prevent scratches or exposure to chemicals.
Don't sleep in it:
• Remove lapis lazuli jewelry before sleeping to prevent unnecessary pressure on the stone, which could lead to chipping or breakage.

Storing lapis lazuli jewelry
Separate storage:
• Store lapis lazuli jewelry separately from harder gemstones to prevent scratches, recommends MOONIQUE creation.
Soft pouch or lined box:
• Keep the jewelry in a soft cloth pouch or a lined jewelry box.
Cool, dry place:
• Store lapis lazuli in a cool, dry place away from direct sunlight or heat, which can fade its color over time.
Consider silica gel:
• Some sources suggest placing silica gel packets in the storage area to help absorb moisture.

By following these care instructions, you can ensure that your beautiful multicolor lapis lazuli jewelry remains in excellent condition for many years to come.
