The Conch is favored for its delicacy meat and prized shell but is in danger of being overfished. It takes a conch four or more years to reach its reproductive maturity, leaving them vulnerable because of demand. These Cast Concrete Conch Shells offer a realistic alternative for outdoor landscaping or as a sculptural element in the home. The detail of the spiral-shelled Cast Concrete Conch is surprisingly true to life. Available in Small and Large.
