A Firth Diamond

Diamonds are among the rarest and most celebrated of all precious stones. Harder than any other known substance, diamonds also possess special light refracting and reflecting abilities, making them the brightest and most colorful of all gems. Mined in just a few exotic locations, with only a select portion being selected as gem-grade, the meticulously cut diamond has come to symbolize beauty, hope, and the promise of eternal love.
