Sea glass

Modern, not fossil — but a steady consolation prize on tooth hunts and a kid's gateway drug to beachcombing. Decades of tumbling in surf gravel produces frosted edges and a soft satin finish. Brown, green, and clear are most common; cobalt blue and red are jackpot rare.

How to spot it

  • Frosted, satin surface — true sea glass is never glossy
  • Edges fully rounded, no sharp facets
  • Brown (beer bottles) and green (wine, soda) dominate; clear is from old window glass
  • Cobalt blue (old medicine bottles) and red (vintage car taillights, ship lanterns) are the rare jackpots
  • Hold to the light — true sea glass is uniformly translucent, not cloudy plastic

Easy to confuse with

  • ·Beach plastic (lighter, often retains glossy spots)
  • ·Modern broken glass (sharp edges, fresh fracture)
