Natural Shell Beads

Frequently asked questions

• Is shell a gemstone?

  Technically, no — shell is organic material formed biologically by mollusks, while gemstones are minerals formed by geological processes. The bead trade groups shell with the gemstone family because it cuts, drills, polishes, and strings like stone, and because designers source it from the same wholesalers. The practical difference is durability and care: shell is Mohs 3.5–4, much softer than nearly any stone in the gemstone catalog, and sensitive to acids and chemicals in ways stone is not.
• What's the difference between mother of pearl and abalone?

  Both are the iridescent inner lining (nacre) of mollusk shells, but from different species. Mother of pearl is the nacre lining of various oysters and freshwater mussels — usually white, cream, or pale pink with subtle iridescence. Abalone is the nacre of *Haliotis* species from Pacific coastlines — strongly iridescent with vivid green, blue, pink, and bronze flash. The flash on abalone is dramatic enough to be the defining visual feature; mother of pearl reads as a soft, subtle iridescent neutral.
• Is spiny oyster shell dyed or treated?

  Spiny oyster is frequently stabilized or resin-impregnated — the natural shell is prone to chipping and cracking at the drill hole, and resin treatment improves durability and color stability. This is widespread industry practice. The vivid orange, red, purple, and pink colors are intrinsic to the shell species (not dye); the resin treatment is for structural integrity. Treatment status should appear on the product page; ask before buying if it isn't specified.
• Is queen conch shell legal to buy?

  Queen Conch (*Aliger gigas*, formerly *Strombus gigas*) is CITES Appendix II listed and has been since 1992. International commercial trade requires export permits from the source country and import documentation in the receiving country. Legal Queen Conch in the U.S. bead trade is sourced from Caribbean fisheries with appropriate CITES permits. Designers planning international resale of finished pieces should check the regulatory requirements for their destination market.
• How do I care for shell beads?

  Shell is the softest material in the gemstone catalog at Mohs 3.5–4 — softer than turquoise, softer than every quartz-family stone, and chemically sensitive in ways stone is not. Avoid acids (lemon juice, vinegar, many household cleaners), perfume and hairspray contact, chlorinated water, and prolonged moisture. Store shell beads separately from harder stones so they don't scratch. Clean with a soft dry cloth or a barely-damp cloth with plain water — no soap, no ultrasonic, no steam cleaning.
