Beaches Around the World
Sand derives its color from minerals that compose it, which vary from place to place. Quartz, often clear or translucent, is commonly the dominant ingredient, lending sand its generally light color.
Pfeiffer Beach, Big Sur, California
Pfeiffer Beach’s purple color comes from manganese garnet deposits.
Red Sand Beach, Rabida, Galapagos
The red sands on Rabida Island are due to the oxidization of lava but some others say that it's because of dead corals.
Punaluu Black Sand Beach, Hawaii
Green Sand In Kourou, French Guiana
The mineral olivine causes the green color.

Unique Glass Beach in California
Glass Beach is a beach in MacKerricher State Park near Fort Bragg, California that is abundant in sea glass created from years of dumping garbage into an area of coastline near the northern part of the town.
In the early 20th century, Fort Bragg residents threw their household garbage over cliffs owned by the Union Lumber Company onto what is now Glass Beach, discarding glass, appliances, and even vehicles. Locals referred to it as "The Dumps." Fires were lit to reduce the size of the trash pile.
The California State Water Resources Control Board and city leaders closed the area in 1967.
