This jewelry piece combines a relatively durable gemstone (snowflake obsidian) with a metal (sterling silver) known for its shine but also its tendency to tarnish. Proper care focuses on protecting both materials.

Understanding the materials
Snowflake Obsidian:
• A natural volcanic glass, rating 5 to 5.5 on the Mohs hardness scale. It is relatively durable but can be scratched by harder materials and is sensitive to strong impacts. It is opaque with a vitreous to dull luster.
Sterling Silver:
• An alloy of 92.5% pure silver and 7.5% other metals, usually copper. It is known for its shine but is susceptible to tarnishing over time when exposed to air, moisture, and certain chemicals.

General care guidelines
Handle Gently:
• Snowflake obsidian can be scratched by harder materials, so handle the jewelry with care.
Put Jewelry on Last:
• Apply cosmetics, lotions, perfumes, and hairspray before putting on your jewelry to minimize exposure to chemicals that can damage the beads or tarnish the silver.
Remove Before Activities:
• Take off the jewelry before showering, swimming, cleaning with harsh detergents, or engaging in strenuous physical activity. Prolonged water exposure can accelerate tarnishing of sterling silver.
Avoid Impacts:
• Do not drop the jewelry or knock it against hard surfaces, as this can chip or break the obsidian beads.
Check Settings:
• Regularly inspect the jewelry for any loose beads or settings and have them repaired by a professional jeweler to avoid loss or further damage.
Avoid Harsh Chemicals:
• Never use commercial jewelry cleaners, ammonia, bleach, or abrasive cleaners on this jewelry. These can scratch the obsidian and tarnish or corrode the sterling silver.
Wipe Gently:
• After each wear, gently wipe the beads with a soft, lint-free cloth to remove oils, dust, and residues.

Snowflake Obsidian Care:
• You can gently wipe snowflake obsidian with a soft, damp cloth, but avoid leaving it submerged for longer periods. Ensure it is thoroughly dried immediately after any contact with moisture.

Sterling Silver Care:
• For light tarnish, use a specialized sterling silver polishing cloth to buff the initial beads. Avoid using abrasive towels or tissues, and polish back and forth, not in a circular motion.
• Do not submerge the jewelry in liquid silver cleaning solutions. If the tarnish is heavy, consider professional cleaning by a jeweler.
No Ultrasonic or Steam Cleaners:
• Avoid these methods as they can damage both components of the jewelry.

Storage
Cool, Dry, Dark Place:
• Store the jewelry in a cool, dry, and dark environment, away from direct sunlight, which can fade colors or damage the materials. Avoid storing in humid areas like bathrooms.
Separate Storage:
• Store the piece individually in a soft pouch or a lined compartment in a jewelry box to prevent scratching, especially between the obsidian beads.
Anti-Tarnish Precautions:
• Since sterling silver can tarnish, store the jewelry in an airtight bag or with anti-tarnish strips or tabs to absorb moisture and slow down the tarnishing process. Avoid storing near sulfur-containing items like rubber, wool, or certain papers.

By following these specific care instructions, you can help preserve the unique beauty and ensure the longevity of your snowflake obsidian and sterling silver initial bead jewelry.
