Sapphire
Sapphires can be divided into two categories: one is solid colored sapphire, which is blue gemstone, and the other is colored sapphire, which has a wide variety of types, including purple, yellow, green, orange, pink, and so on.
The British once said, "Mary in blue, love is true." In European tradition, sapphire is seen as a symbol of loyal marriage, with a unique blue tone symbolizing eternal and steadfast love.
In Greek and Roman culture, wearing sapphires can bring endless wisdom and courage.
