Sapphire Beach is a popular tourist destination on the island of St. Thomas in the U.S. Virgin Islands. The beach is known for its clear, turquoise waters and white sand.

The history of Sapphire Beach can be traced back to the indigenous Carib and Arawak tribes, who were the first inhabitants of the Virgin Islands. The island of St. Thomas was later claimed by the Danish West India Company in 1671, and the beach would have been used by the Danish colonizers for activities such as farming and trade.

In 1917, the U.S. Virgin Islands were officially acquired by the United States from Denmark. During the 20th century, tourism began to develop as a major industry in the Virgin Islands, and Sapphire Beach became a popular destination for visitors looking for beautiful beaches, snorkeling, and other water activities. Today, it's one of the most visited beach in St. Thomas, USVI.
