14k gold ring means that the ring is made from 58.3% gold and 41.7% other metals. As pure gold (24k) is too soft, gold jewelry often contains other metals, such as silver, copper, nickel or zinc, to make the piece more durable. 14k on a gold ring is an expression of the gold content in the ring (or any gold item). As other have stated, 14k means that the ring is 14 parts gold out of 24 parts metal since pure gold is called 24k. So 14 divided by 24 equals .583333 which means 14k is 58.3% gold and 41.7% other metals.
